Ravishankar Agrociencias miRNA banana heat stress thermo protective genes Acquired thermo tolerance MicroRNAs are a class of small regulatory RNAs in plants, which play vital roles during various abiotic and abiotic stress conditions including plant processes. In this present study, we examined the expression of miRNAs and their predicted target expression levels during heat stress in banana. Out of 235 miRNA found in Musa, 40 miRNA showed homology to heat responsive miRNAs from other plants. Further, 14 targets for miRNA were predicted that are potentially regulated by their cognate miRNAs and were monitored under three stages of stress viz, induction, induction + lethal alone using qPCR analysis. The results suggest that generally, there is a negative relationship in the expression patterns of miRNA and their predicted cognate targets - HSP70, HSP90, SAP, DNAj genes. These were highly up regulated and their respective miRNAs showed lower expression. This is the first report in banana, which demonstrated that during induction stress, various thermo-protective genes are activated at initial stages of stress to achieve thermotolerance through altered miRNA expression. The results will help in broadening our understanding acquired thermotolerance and their regulation by miRNAs in plants. 2018 artículo científico 0973-354X https://www.redalyc.org/articulo.oa?id=577077092016 fr http://www.redalyc.org/revista.oa?id=5770 Journal of Horticultural Sciences application/pdf Society for Promotion of Horticulture Journal of Horticultural Sciences (India) Num.1 Vol.13 |
