摘　　要：Auxin is a key hormonal regulator,that governs plant growth and development in concert with other hormonal pathways.The unique feature of auxin is its polar,cell-to-cell transport that leads to the formation of local auxin maxima and gradients,which coordinate initiation and patterning of plant organs.The molecular machinery mediating polar auxin transport is one of the important points of interaction with other hormones.Multiple hormonal pathways converge at the regulation of auxin transport and form a regulatory network that integrates various developmental and environmental inputs to steer plant development.In this review,we discuss recent advances in understanding the mechanisms that underlie regulation of polar auxin transport by multiple hormonal pathways.Specifically,we focus on the post-translational mechanisms that contribute to fine-tuning of the abundance and polarity of auxin transporters at the plasma membrane and thereby enable rapid modification of the auxin flow to coordinate plant growth and development.
