Unit III:
Functional and ultra structural changes in chloroplast membranes,
mitochondria and cell wall during senescence and ripening.
Unit IV:

regulatory role of ethylene in senescence and ripening, biotechnological
approaches to manipulate ethylene biosynthesis and action.
Unit V:

genetic modification of post harvest life on flowers and fruits.Uses of
GM crops and ecological risk assessment.
