A Novel Stay-Green Mutant of Rice with Delayed Leaf Senescence and Better Harvest Index Confers Drought Tolerance.

Further, for all the 15 genes studied, the mutants as well as the WT showed an increasing trend in gene expression with the progression of time under incubation, irrespective of whether they are up or downregulated, i.e., the expression of the genes increased as the time under dark condition increased and this rate of increase was the highest in the WT followed by SGM-3, while SGM-1 and SGM-2 were at par showing the least rate of increase ( Figure 3 and Table S2 ).
