Technical Abstract: Several classes of small RNAs have been studied in plants with the most extensively studied class being microRNAs (miRNAs). microRNAs (miRNAs) are an endogenous class of 20-25 nucleotide noncoding RNAs that are thought to play an important role in regulating gene expression by targeting mRNAs for cleavage or translational repression. To date, several miRNAs have been identified in different plants species and their regulatory roles in growth and development studied. A smaller number of miRNAs have been found to be involved in response to abiotic stresses, now even this area remains unexplored in most crop plant species. We have initiated a study focused on the identification of conserved and novel small RNAs in peanut (Arachis hypogaea) and the elucidation of their role in abiotic stress responses. We will report our findings on small RNA expression in heat- and drought-stressed leaf tissues and present a preliminary analysis of novel small RNAs identified in peanut.
