The large pleiotropic effects of AcRR1 elucidated in this work are attributed to the regulation of several sets of target genes. Direct regulation of TaWOX11-2D by AcRR1 and elevated cytokinin levels lead to reduced floret abortion, thus contributing to an increased GNS. Direct regulation of TabHLH25-5B by AcRR1 activates TaFTs and confers a pronounced early-heading phenotype. The target genes work together to increase the yield of wheat.
