Abstract:
:The expansion of gene families for miRNA and tasiRNA, small RNA effector proteins (ARGONAUTEs or AGOs), and miRNA/tasiRNA targets has contributed to regulatory diversity in plants. Loss or acquisition of small RNA-generating loci and target site sequences in multigene families represent striking examples of subfunctionalization or neo-functionalization, where regulatory diversity is achieved at the post-transcriptional level. Differential regulation of small RNA and target gene family members, and evolution of unique functionality of distinct small RNA-AGO complexes, provide further regulatory diversity. Here, we focus on the idea of distinct small RNA-target transcript pairs as nodes within biological networks, and review progress toward understanding the role of small RNA-target nodes in the context of auxin signaling.
