PhD position availible in plant physiology

[Kristina Rizzardi]

Uppsala University hereby declares the following position to be open  
for application:

PhD student position in Physiological Botany
at the Evolutionary Biology Centre, the Department of Physiological  
Botany (http://www.ebc.uu.se) announces a PhD student position in the  
project “The role of the Arabidopsis HETEROCHROMATIN PROTEIN1 in plant  
development”.

In plants as well as in animals the control of chromatin structure in  
response to endogenous and exogenous cues determines gene expression  
patterns that regulate cell differentiation and development. The  
available project focuses on an Arabidopsis mutant, terminal flower2  
(tfl2). The gene encodes the plant HETEROCHROMATIN PROTEIN1 (HP1), a  
homologue to the Drosophila HP1 genes that are involved in basic  
processes as DNA replication, recombination and repair but also in  
epigenetics and gene activation/repression during differentiation. The  
single copy gene in Arabidopsis encodes a protein most similar to HP1  
proteins that regulate gene activation/ repression in other organisms  
and it has been shown to localize to euchromatic regions of the  
chromosomes. Mutations in tfl2 have a pleiotropic effect indicating a  
global role, possibly regulating different developmental processes in  
response to light. Our data points to the importance of TFL2 in two  
phase-transitions during the plant life cycle: embryo – postembryonic  
development as well as vegetative – reproductive development. Recent  
results show that TFL2 physically interact with proteins in hormone  
signal transduction pathways as well as chromatin of both hormone  
biosynthesis and response genes. The successful candidate will  
collaborate with another PhD student in this area of hormone  
regulation of plant development.

The successful candidate should have a university degree in biology,  
favourably with the combination of plant biology and molecular  
biology. The application should include personal background including  
a description of undergraduate training, a complete CV, copies of  
university degree and degree thesis as well as the names and e-mail  
addresses to two referees.

The PhD position is full time employment position for a tenure of four  
years. However, the possibility for the tenure to be extendable to a  
maximum of five years exists to allow the inclusion of university  
level biology teaching and/or laboratory supervision into the PhD  
education.

For more information please contact Dr Annika Sundås-Larsson, that  
will function as the supervisor, by e-mail  
annika.sundas-larsson@... or by phone [phone]. Union  
representatives are Anders Grundström, SACO-rådet, tel: [phone]  
5380, Carin Söderhäll, TCO/ST, tel: [phone] and Stefan  
Djurström, SEKO, tel: [phone].

The application should be sent , preferrably by e-mail to:  
registrator@..., or by fax + 46 18 471 2000, or by mail to:  
Registrar´s Office, Uppsala University, Box 256, SE-751 05 UPPSALA,  
Sweden. In any correspondence, please use the reference number UFV-PA  
2009/2423. Application no later than 16 November, 2009
