bean is (Phaseolus vulgaris) widely grown legume worldwide and
is the most important pulse crop in the Indian subcontinent. The
productivity is adversely affected by a large number of biotic and
abiotic stresses. Micro RNAs (miRNAs) have been implicated in the
regulation of plant responses to several biotic and abiotic stresses.
Boron (B) toxicity is a significant limitation to cereal crop
production worldwide. In this study, RT-qPCR confirmed seven miRNAs
were responsive to boron toxicity. The known predicted targets and
their functional analysis revealed that most of the targets represent
transcription factors. GO results supported our hypothesis that
miRNAs were found to be involved in diverse cellular processes,
including plant circadian cycle, vegetative development,
transcription, and cross adaptation. The results obtained would
provide new insights to the complex regulatory mechanism employing
small non-coding regulatory RNAs toward stress adaptation.
