Abstract

In fruits, microRNAs (miRNAs) are responsible for the essential biological and metabolic processes involved in the growth, development, biosynthesis of several compounds, and response to various environmental stresses. In recent years, scientists have discovered various biotechnological tools and applied them to crop development for improving the quality and yield of the crop. Among these, miRNA has become an important target. Scientists have identified several miRNAs which play a major role in the physical and chemical (compositional) changes during the developmental cycle of fruits. In this article, the possible contribution of plant miRNAs in the development and ripening of various climacteric and non-climacteric fruits by targeting various genes and transcription factors has been focused which would certainly open new avenues in the field of fruit-ripening research and postharvest biology. Various fruit cultivars developed utilizing miRNA manipulations have also been discussed in this review. The recent studies on the miRNAs in fruit development and ripening summarized in this review may add new dimensions in horticultural research.
