A microRNA expression atlas of grapevine based on small RNA library sequencing

ABSTRACT: Genetic and epigenetic regulations, mostly driven by small non-coding RNAs, play a crucial role to define genetic programming in plant biology and development. In this work, we focus on miRNAs, the most representative class of small RNAs, to present the first comprehensive miRNA expression atlas in Vitis vinifera L. Our atlas gives a clear picture of miRNA regulation and homeostasis in the whole plant during its lifecycle. We analyzed 68 small RNA libraries, which were prepared from a rich and diverse number of tissues (13) harvested on different developmental stages. We identified 110 known miRNAs and annotated 176 novel, some of which belonging to known families and others completely new. We found that very few miRNAs may be defined as tissue specific. However, interestingly, in the
