Salient Achievements:

Proposed for a multi-cell C4 photosynthetic pathway (non-Kranz and NAD-ME dependent) involving three tissue types (outer pericarp, inner pericarp, and endosperm) in developing wheat grains.    

Discovery of an in planta photorespiratory bypass mediated through chloroplastic pyruvate dehydrogenase gene (cpPdc) in developing rice grains, and this happens to be the shortest C2 shuttle known till date.

Discovery of C4 photosynthetic pathway in developing wheat grains - a classical C3 plant

Proposed for the evolution of an intermediate type C4 photoysnthesis (without Kranz) in non-foliar photosynthetic organ (developing grain) in BOP clade (eg: wheat) prior to the evolution of an efficient foliar C4 photosynthesis in PACMAD clade (eg: sugarcane)

Proposed a concept through transcriptome studies in sesame, longer duration of expression of the genes of oil biosynthesis (early onset, by 10 dpa and sustained till 30 dpa) accommodates a broader window of time for active oil accumulation is crucial for higher oil yield in sesame.

Identification of novel genes and involvement of genes known for carbohydrate metabolism in imparting heat stress tolerance during grain filling in wheat.
