The divergence of natural stress tolerance mechanisms between species is an intriguing phenomenon. To study it in rice, a comparative transcriptome analysis was carried out in 'heading' stage tissue (flag leaf, panicles and roots) of Nagina 22 (N22; drought‐tolerant) and IR64 (drought‐sensitive) plants subjected to field drought. Interestingly, N22 showed almost double the number of differentially...
Main conclusionDrought-tolerant rice variety, Nagina 22 (N22), has a unique spikelet miRNome during anthesis stage drought as well as transition from heading to anthesis. Molecular characterization of genetic diversity of rice is essential to understand the evolution and molecular basis of various agronomically important traits such as drought tolerance. miRNAs play an important role in regulating...
Evolution of differential regulatory mechanisms can lead to quite distinct physiological attributes. In the present study, we have identified one such regulatory schema that regulates osa‐miR408 and responds differentially in drought‐sensitive and ‐tolerant indica rice varieties. A comparison of the drought stress response in drought‐sensitive (Pusa Basmati 1 and IR64) and drought‐tolerant (Nagina...
