Genome-wide identification of DCL, AGO, and RDR gene families in wheat (<i>Triticum aestivum</i> L.) and their expression analysis in response to heat stress.

ABSTRACT: Key components of the RNA interference (RNAi) pathway include the Dicer-like (DCL), Argonaute (AGO), and RNA-dependent RNA polymerase (RDR) gene families. While these components have been studied in various plant species, their functional validation in wheat remains unexplored particularly under heat stress. In this study, a comprehensive genome-wide analysis to identify, and characterize DCL, AGO, and RDR genes in wheat and their expression patterns was carried out. Using phylogenetic analysis with orthologous genes from Arabidopsis and rice, we identified a total of 82 AGO, 31 DCL, and 31 RDR genes distributed across the 21 chromosomes of wheat. To understand the regulatory network, a network analysis of miRNAs that target RNA-silencing genes was
