Functional Genomics

Attempts are being made to understand the mechanism of fruit ripening by using microarray approach. One of the area of interest is to find out a sub-set of ethylene responses which are specific to fruit ripening and are not general ethylene responses. More than 80 genes related to ripening of tomato fruits have been cloned. Some of the genes of interest related to fruit ripening and biotic stress would be analyzed by transgenic approach. An efficient system for tomato transformation system is available, and has already been utilized for expression of antigens of Vibrio cholerae, targeted towards development of edible vaccine against cholera. A micro-array facility is already functional at the site.
