looking for a post-doctoral position

Wed Jun 17 21:17:38 EST 1998


I am a graduate student (plant biology) at Laval University, Quebec
city. I am submitting my thesis this month and would be defending in
August.I am therefore looking for a post-doctoral position where I can
apply knowledge of molecular bioogy, biochemistry (enzymology). I would
be available from the month of September, 1998. 

During both, my pre-doctorate and doctorate studies, I have got
experience and am well versed with molecular, biochemical and tissue
cultural techniques.

As a graduate student, I worked on research project aimed at
'Identifying, isolating and characterizing a cysteine proteinase
inhibitor specific to the digestive proteinases of potato pest, Colorado
potato beetle, and its application in pest control.'

I was successful in inducing a novel cysteine proteinase inhibitor via a
gamma-linolenic signalling pathway.

This is first kind of a study in plants where an unusual fatty acid,
gamma-linolenic acid, is involved in inducing defense response in
plants, one of the defense molecules being a cystatin, a cysteine
proteinase inhibitor. With isolation and purification and biochemical
characterization of this cystatin, our lab is now concentrating on
elucidating the defense pathway, and also in isolation of the cystatin
gene induced in response to the GLA treatment in tomato leaves.

As a research assistant I have worked on projects involved in:
1) the regulation of expression of a rice and Pigeon pea seed storage
protein during seed development.
2) isolating and characterizing photosynthetic variants in cultured
cells of Chenopodium rubrum, in response to chronic exposures of DCMU
and high temperature conditions.
3) Organization of repeat DNA in the genome of various pigeon pea

I have included resume for reference.

Thank you,

Sincerely yours,
Savita Visal
