Hi,
there are just few proteins or cDNA sequences for Curculigo
latifolia / C. capitulata and Hypoxidaceae in general. So you will be
going for de novo protein sequencing. This will make sense if you want
to spot a difference, say between ripe / non-ripe fruit .
As a method for characterising proteome, de novo protein sequencing is
to costly/to low throughput.
IMHO it is way easier to go for EST sequencing first, as a stepping
stone for proteome characterisation.
Best,
darked
