Gene Symbol
- Os01g0907600 <=> OsSAG12-1,SAG12-1
Function
- OsSAG12-1 is a negative regulator of cell death in rice.
Phenotypic analysis
- The figure 3A shows differently growing T2 plants obtained from a single T1 plant. All RNAi lines showed reduced overall growth including height compared to the vector transformed plants (figure 3B). Figure 3B shows the average and standard deviation of heights of the T1 progeny plants obtained from 4 independent T0 RNAi lines and vector-transformed plants at 60 days after sowing.
- Other than those extreme phenotypic plants that died early, most of the remaining plants also showed accelerated senescence phenotype especially in their flag leaves. The flag leaves from RNAi plants showed com- paratively early senescence compared to vector-transformed plants (figure 3C).
- Flag leaves are the primary source of nutrient mobilization during the grain filling stage of rice and showed faster senescence compared to the other leaves (Biswas and Choudhuri, 1980). Majority of the other leaves also showed a range of early senescence phenotypes.
- While the tips of most of the leaves from vector-transformed plants were green after 60 days, the RNAi plants showed varied degree of senescence (figure 3D). This is in contrast to the flag leaves that showed early senescence throughout the leaf blade.
