OAR@ICRISATExpression Analysis of Novel microRNAs in Rice During High Temperature StressBSailajaauthorS KMangrauthiaauthorS RVoletiauthorDSubrahmanyamauthor-BrajendraauthorVRavindra BabuauthorMicroRNAs (miRNAs) are small non-coding RNAs which play an important role in regulating the genes involved in plant growth and development. Several studies showed that miRNAs are involved in plants response to different kinds of abiotic stresses also. In our previous study, temperature responsive miRNAs were predicted in O.sativa. 27 miRNAs were predicted to be novel in rice using homology search. In continuation to our previous study, expression of 14 novel miRNAs was done in shoot and root of 13 days old seedlings of five different rice cultivars using real time PCR. Expression these miRNAs was analyzed in control and high temperature stress environment. Out of 14 predicted novel miRNAs, two novel miRNAs- miR157a and miR165a showed expression in all five rice cultivars. Interestingly, miR165a showed a differential expression pattern among heat tolerant (N22, IR64 and Rasi) and susceptible (Vandana and Sampada) cultivars suggesting that it might have specific role in high temperature tolerance.Abiotic StressRiceGenetics and GenomicsClimate Change2017Academy for Environment and Life Sciences, IndiaArticle
