  • Cell morphogenesis and its deposition pattern are crucial for plants to ensure functional tissue and organ structures, particularly because the relative positions of plant cells do not change after proliferation. Root-hair formation provides a simple model system that allows exploration of the mechanisms that regulate both pattern formation and morphogenesis. The root-hair pattern of Arabidopsis is determined through a regulatory circuit composed of transcription factor genes. The HD-Zip gene GLABRA2 has been considered a key component,acting farthest downstream in this regulation. Using an inducible system, the phospholipase D gene (AtPLD1) was identified as a direct target of GL2. Expression of AtPLD1 promoted root-hair development. Taken together the data demonstrate that GLABRA2 regulates root-hair pattern formation by repressing genes for root-hair development in hairless cells. Because PLD affects cell morphogenesis, GLABRA2 very likely acts as an intermediary between the transcriptional regulatory circuit and the morphogenic effects of PLD. (literal)

Abstract
  • The root-hair pattern of Arabidopsis is determined through a regulatory circuit composed of transcription factor genes. The homeobox gene GLABRA2 (GL2) has been considered a key component,acting farthest downstream in this regulation. GL2 modified to include a transactivating function caused epidermal cells to develop ectopic root hairs or root hair–like structures. With this system,the phospholipase D gene (AtPLD1) was identified as a direct target of GL2. Inducible expression of AtPLD1 promoted ectopic root-hair initiation. We conclude that GL2 exerts its regulatory effect on root-hair development through modulation of phospholipid signaling. (literal)
