Dear

I am working on the uses of the mosses on biomapping of the atmospheric metal precipitration in the klarger areas.

In this connection, we we want to examine the the moss for the toleranceb before inducting them for biomapping programm.

We want to know that by using PEA (photosynthesis Efficiency Analyser) is it possible to measure (to get an idea w that which species is tolerance) the tolerance so that we can identify the tolerance and sensitive species.

It is my presumption that upon metal treatment, if there is abrupt change in the fluorescence value ( 0.9) then species can not be put in the category of the tolerance.

Please give your opinion.

regards

Question regarding photosynthesis -- PSI & II

2009-09-23T13:05:19Z

Question regarding photosynthesis -- PSI & II

I am reposting this message for a librarian seeking information. Please reply here and directly to LTYLER@...

I have a researcher who thinks that there is either a specific calculation, a standard formula or particular known quantity for the amount of power ( or charge or energy ) that is transferred from Photosystem II to Photosystem I within a photosynthetic system of a plant or algae.

I have discovered many calculations for the process; I see a lot about the timing of the transfer but not the amount of transfer. Some articles deal with the percent of energy transferred from PS I to PS II or vise versa but don't give an actual measurement of the amount of charge transferred, just the percent. One paper seemed to reference it and seemed to make it look like it was a known quantity which makes us think we are making this too hard.

Any enlightenment your professors may provide for our understanding would be greatly appreciated.

Thank you for your time.

Sincerely,

Re: Re:

Dear Colleagues,
Good afternoon. We are trying to perform a photosynthesis
experiment that requires us to directly measure O2 production levels
from leaves. Our equipment only allows us to measure O2 concentrations
greater than 50 ppm, but we need a more sensitive sensor that allows
for measurements less 50ppm.
Could you advise us on how to proceed on obtaining such a sensor?
Thank you,
Stephane & Ronex

Chlorophyll Fluorescence

2009-04-13T19:08:15Z

To the Photosynthesis Depart at net.bio.net,

I have an interested inquiry regarding the topic of chlorophyll fluorescence, I have recently been posed a question from one of my colleagues regarding the result of fluorescence of a chlorophyll a molecule (a. maxima of lambda 662) under visible green light (lambda 510). I believe that there was a mathematical way to determine this, however knowing that visible green light isn't fully composed of "green" light, would the flurorescence remain red?

Thank you,

James Hong

Anthony San Pietro (1922--2008) is deceased

2008-09-21T22:42:22Z

Readers of Photosyn@...
President of ISPR Jim Barber
Past President of ISPR Eva-Mari Aro
Treasurer of ISPR: Barry Osmond

I am extremely sad to share with you the news of Tony San Pietro's death
on September, 13, 2008. Please read the letter from Tony's family.
Hopefully, ISPR will be able to inform its members about it through its
web site.
Kind regards,

Govindjee
--------------------------------------------------------------------------

It is with great sadness that I inform you of the passing of our beloved
father Anthony (Tony) San Pietro.

Jodie San Pietro
-------------------------------------------------------------------

Anthony G. San Pietro, 86
April 22, 1922 - September 13, 2008

Anthony G. San Pietro passed away on September 13, 2008 at the Meadowood
Health Pavilion at the age of 86.

Born on April 22, 1922 in Brooklyn, New York, Tony (as he was known to
friends and colleagues) originally aspired to become a singer. When he
was in high school, he purchased booklets of song lyrics from street
vendors and emulated the popular singers of the time. Despite his
obvious talent, he chose instead a career path in scientific research
and education, which spanned fifty years.

Tony graduated from New York University in 1942. He was inducted into
the Army in October 1942 and entered the Army Specialized Training
Program (ASTP) where he studied electrical engineering. Upon completion
of the ASTP, he spent the remainder of his military service at the
Manhattan Project, Los Alamos, New Mexico as a member of the
Biochemistry Group. After military service, he attended graduate school
at Columbia University where he was awarded his Ph.D. in Biochemistry in
1951.

The decade Tony spent at Johns Hopkins University was memorable both on
a scientific and personal level. He held a post-doctoral position in
biochemistry from 1952 to 1954. In 1954, he joined the faculty as an
Assistant Professor in Biology and the McCollum- Pratt Institute. He
became an Associate Professor in 1959. It was during his time at Johns
Hopkins that Tony met his future wife, Alice King, who was working as an
X-ray technician. Even fifty years later, he still fondly remembered
every detail of their first date.

He joined the Charles F. Kettering Research Laboratory in Yellow
Springs, Ohio in 1962, where he was involved in the creation of a
first-rate laboratory in Photosynthesis and Nitrogen Fixation Research.
While in Yellow Springs, he also made time to teach a biochemistry
course at Antioch College.

Tony San Pietro served as the Chairman of the Plant Science Department
at Indiana University, Bloomington from 1968 until 1977. He became a
Charter Member of the Johns Hopkins Society of Scholars in 1969. He
was given the title of Distinguished Professor of Plant Biochemistry by
Indiana University in 1975. He was especially proud to be elected to
the National Academy of Sciences in 1983. He was also awarded an
Honorary Doctor of Science Degree by Purdue University in 1992 and
retired from the Indiana University faculty that same year.

During his fifty years in science, Tony was fortunate to have
collaborated with a large number of scientists from around the country
and all over the world. He traveled extensively -- including fourteen
trips to Japan before he retired. A number of Japanese scientists came
to do research in his laboratory both in Yellow Springs and Bloomington.
Similarly, he had extensive collaboration with scientists from European
countries, England and Israel. He was truly honored to have their
friendship as well as their respect. His service with international
programs of the National Science Foundation and the National Research
Council helped place Indiana University prominently on the international
map.

Tony continued to make contributions to the educational and scientific
communities after his retirement. He participated in the Faculty and
Staff for Student Excellence (FASE) mentoring program until 2003. He
was instrumental in creating an Alliance for Minority Participation in
Science, Mathematics, and Engineering. He worked as a consultant for
the Solar Energy Research Institute (later National Renewable Energy
Laboratory, NREL) in Golden, CO from 1978 to 1982 and again from 1995 to
2006. He also began a consulting agreement with COOK Biotechnology,
Inc. in West Lafayette, IN, in 1997, which continued until recently.

Tony San Pietro is survived by his loving children, James Robert of
Lafayette, IN, Laura Ellen of Studio City, CA and Judith (Jodie) Alane
of Springfield, VA. He was preceded in death by his dear wife Alice, a
well-known watercolor artist and his parents Rimetrio (James) and Maria
(Cibelli) San Pietro.

Funeral services will be announced at a future date. Memorial
contributions to the American Heart Association and the American Cancer
Society will be sincerely appreciated.

Thomas Roosevelt Punnett (1926--2008)

2008-09-11T20:08:22Z

Dear Photosynthesis Colleagues:

Thomas Roosevelt Punnett Jr., 82, Professor Emeritus at Temple University,
who had a sharp intellect, superb teaching skills, and a great sense of
humor, died July 4, 2008 of Cancer. He was born on May 25, 1926, in
Buffalo, NY.

If anyone wishes to provide any testimonial or tribute to his life is
requested to send his/her write-up to Govindjee (gov@...) since
a TRIBUTE is planned for publication in "Photosynthesis Research" at a
later date.

Tom finished his PhD in Physico-Chemical Biology, in 1954 under Robert
Emerson at the University of Illinois at Urbana-Champaign. He had
discovered, for his thesis, that algal chloroplasts produced oxygen
(Nature, 1953). He then worked as a post-doctorate fellow in biochemistry
at Cambridge, UK, and then as a Faculty member at Rochester University
(1956--1963). He then moved to Temple University in Philadelphia, where he
retired in 1999. He is author of many scientific publications and had an
important patent to his credit.

He is survived by his wife Dr. Hope Handler Punnett; 3 daughters (Laura,
Susan and Jill) and 7 grandchildren.

Govindjee

query on quantum efficiency and yield

2008-08-19T08:01:27Z

Hi All,

I've a query in understanding quantum yield and quantum efficiency

quantum yield can be defined as the ability with which the plants trap
photons whereas quantum efficiency can be ability with which plants
transfer the trapped energy towards photochemistry.

is the above defnition true?

Also
Can I use a PAM pulse modulated flurometer to measure both the
parameter? My problem is I've few plant species and i want to see
which one is doing its best in the same environmental condition. Can I
use these two parameter to judge the best out of the list I've?

Thanks & Regards,
Parameshwaran V

Purple Bacteria

Why can't purple bacteria survive where there is oxygen around, even
though there is plenty of hydrogen sulfide around, too?

Photsynthesis

2008-07-27T13:56:28Z

In cyclic photosynthesis, purple bacteria use cytochromes to pump
hydrogen ions out of the cell. Where do the hydrogen ions come from? I
don't think it's hydrogen sulfide, because I thought hydrogen sulfide
was only used to replenish chlorophyll's electron when its excited
electron is used to reduce NADP to NADPH.
Thanks.

Hydrogen sulfide bacteria

2008-07-27T13:51:12Z

What is the source of energy L. luymesi uses at the bottom of the
ocean to split hydrogen sulfide? I assume it is heat energy, and that
the hydrogen is used to reduce carbon dioxide. Correct?

item suggestion

2008-05-28T12:53:36Z

Hi,

I am a fellow at the systems biology department in Harvard, and I am very interested in photosynthesis research. Have been enjoying getting useful information through your mailing list.

I thought the following item might be of interest even though more general than photosynthesis per se.

Best,

Ron

BioNumbers – the database of useful biological numbers

Dear all,

I have a non-standard post, but one that will hopefully be of interest to this community. A group of us in the systems biology department at Harvard Medical have built a database to store useful biological numbers ( www.bionumbers.org ), such as cell and organelle sizes, diffusion coefficients, protein concentrations, and much more ranging from molecular biology to physiology and ecology.

We built the database because of a common realization of how many hours it can take to find even the most trivial numbers in the biological literature. And then once the number is found, where to store the information for future use? Bionumbers is more permanent and more searchable than post-it notes. The site is meant to rapidly connect you to literature sources - a sort of Pubmed for numbers, and provide wiki-like to comment on numbers as well as contribute new numbers.

Please check out our database and maybe even enter some numbers you would like to keep track of - all database users will benefit from your entry. BioNumbers is a long-term project and will be continually improved for the foreseeable future. Any suggestions to make the database more useful are very welcome ( bionumbers@... ).

Re: Photosyn Digest, Vol 27, Issue 1

2008-03-24T14:38:18Z

Dear David,

This does not exactly answer your question in the units you are looking for, but colleague at the University of Wisconsin-Oshkosh had Cladaphora analyzed as a biofuel and found it to have a fuel value better than pine, but a bit less than oak. I can probably get the exact numbers. He is interested in the health of the Great Lakes, where Cladophora is greening over the typically oligotrophic waters, and was looking for options to get it cleaned up. This seems to support the DOE claim rather than refute it given its 'weed' status and growth rate. Growing an oak tree to harvest takes a good deal longer than a few warm summer months.

Biodiesel etc

2008-03-22T09:41:15Z

Biodiesel etc “Algae yields have not yet been accurately determined, but DOE is reported as saying that algae yield 30 times more energy per acre than land crops such as soybeans, and some estimate even higher yields up to 15000 gpa”

I read statements such as the above with increasing scepticism. Does anyone have verifiable figures (in tons per acre per year) of biomass for algae such as Chlorella or Spirulina ?
Many thanks

chlorophyll a & chlorophyll b

2008-02-27T20:54:34Z

Why does chlorophyll a called the "a" and chlorophyll b called "b"? Is
there a historical reason or any other reasons?

Any resources regarding this matter would be helpful.

Thanks

in gel chlorophyll fluorescence

2008-02-08T09:46:51Z

Hi All,

I wonder if it is possible to see chlorophyll fluorescence in gels. We would like to run non-denaturing polyacrylamide "green gels" to detect chlorophyll-protein complexes through detection of the red fluorescence of chlorophyll. Is this possible? Any tips?

Thanks a lot,

Glucose is no more a product

2007-12-19T03:21:40Z

Glucose is no more a product Forgive me for returning to an old theme that I have troubled you with in the past.

For half a century or more, it has been clear that the path of
starch synthesis in chloroplasts starts with triose
phosphates and progresses to polymer formation via
glucose-1-P rather than free glucose. Glucose is no more a product of carbon
assimilation by illuminated chloroplasts than is sucrose.
So, why do textbooks insist that it is?.

If you wish to read a recent article about this you can find it by pasting
DOI 10.1007/s11120-007-9139-3
into Google

Best Christmas wishes

Re: [Ecophysiology] C4 pathway plants

2007-10-14T05:15:54Z

Dears Mark and Ellen,

You can get the C4 pathway list of plants from Photosynthetica 1992,
26:323-331 and Photosynthetica 1978, 12:200-208 (attached file).

To distinguish between C3 and C4 plants you have to provide either
measurement of compensation point or do measurements of photosynthesis at
1% and 21% of O2 in sample air using any closed system for photosynthesis
measurements (IRGA) like CIRAS-2 or TPS-2 from PP Systems Company
(http://www.ppsystems.com).

I hope that this will help.

Sincerely,

Dr. Hazem Kalaji

Sad News: Elizabeth L. Gross passed away on June 27, 2007

2007-10-11T22:25:20Z

Sad News: Elizabeth L. Gross passed away on June 27, 2007

Professor Elizabeth L. Gross, Professor Emeritus of Biochemistry, The Ohio
State University (OSU) , Columbus, Ohio, passed away on June 27, 2007. She
was a pioneer in the area of Biophysics and Biochemistry of
photosynthesis. In the recent past, she studied the Structure and
Function of Plastocyanin, and Cytochrome f, especially the interaction
between these proteins and the electron transport process in
photosynthesis, using both experimental and computational approaches.
Elizabeth (friends called her Liz) was born in 1940. She obtained her BA
(Biophysics), in 1961, from the University of California at Los Angeles
(UCLA), and her PhD (Biophysics) from the University of California at
Berkeley, in 1967, under the guidance of Lester Packer. Liz did her
post-doc research with Tony San Pietro, at the Kettering Research Lab,
from 1967-1968. From 1968, Liz has been on the faculty in Biochemistry at
the Ohio State University; she retired in 2006 after ~39 years of service.
She had advised 13 graduate and 6 postdoctoral students. She had also
collaborated with Charlie Arntzen, Dick Dilley and Govindjee. Liz has
published over 65 top research papers mostly in Archives of Biochemistry
and Biophysics , Biochimica et Biophysica Acta, and Biophysical Journal,
but also in Biochemical and Biophysical Research Communication,
Biochemistry, Photochemistry and Photobiology, Photosynthesis Research,
Plant Physiology and Nature,

Chronologically, her former PhD students were: Dan D, Davis; Lawrence
Prochaska; Joseph Laszlo; Kent O. Burkry; Rong Long Pan; Douglas G.
Sanderson; George Anderson; Stewart Durell; Steven Molnar; Douglas C.
Pearson, Jr., and Esmail J. Haddadian. Her postdoctoral associates,
again, chronologically were: Masaki Takahashi; Peter Abdella; Ravindra
Bhardwaj; Yiji Fan; Baishnab Tripathy; and James Draheim.

A detailed obituary of Elizabeth L. Gross is currently being prepared by
Richard Sayre, of OSU, in cooperation with the former students of Liz, for
publication in Photosynthesis Research.

She is survived by her husband Bob and family members.

'A New Leaf in Time'

2007-08-21T14:37:55Z

'A New Leaf in Time' At the recent international congress (PS 2007) in Glasgow I gave a short talk about 'A New Leaf in Time', a digital book of mine, in PDF, about photosynthesis and how green creatures have shaped the world. A summary of this exercise in ‘vulgarisation’ can be found at

http://www.dawalker.staff.shef.ac.uk/daw/anlits.pdf

If you find this of interest and would care to Email me I will tell you from where it may be downloaded (0pen Access) in its present entirety.

Best regards

Rate of O2 generation/CO2 consumption

2007-08-18T12:54:08Z

Hello, I found this question, I have a similar project but rather than looking at the amount of O2 the plants produce, I was wondering if you had a source that showed the top plants that have the greatest efficiency of CO2 consumption.

>I was wondering if somebody could point me toward a good reference
>explaining the rate at which plants are able to consume CO2 and generate
>O2 via photosynthesis. I am interested in using plants as part of
>an air regeneration project, so I would like to find plants which
>are easily and rapidly grown, and can regenerate O2 quickly. I need to
>get specific numerical information about the O2 generation rate.

>Are there any genetically engineered plants for this specific purpose?

Thank you for your assistance,

Liam Savage
