PhD: University of Kalyani (1981)
CSIR has sanctioned a project and we have started to work on the
expression of the gene for sucrose phosphate synthase in Banana fruits.
Two projects are likely to be sanctioned by DBT, Govt. of India. One is on
cloning trans-acting factor from Tomato, the other is on production of
transgenic rice overexpression OSBZ8.
With Prof. A.N. Lahiri Mazumder, I am acting as Co-PI in a DBT sanctioned
project on Poteriscia quatcata ( Wild rice )
