Hormone interactions at the root apical meristem

摘要: Plants exhibit an amazing developmental flexibility. Plant embryogenesis results in the establishment of a simple apical-basal axis represented by apical shoot and basal root meristems. Later, during postembryonic growth, shaping plant body continues formation activation numerous adjacent meristems that give rise to lateral branches, leaves, flowers, or roots. This plasticity reflects important feature plant's life strategy based on rapid reaction different environmental stimuli, such as temperature fluctuations, availability nutrients, light water response resulting modulation programs. hormones are endogenous factors for integration these inputs regulation development. After period studies focused primarily single hormonal pathways enabled us understand hormone perception signal transduction mechanisms, it became obvious output mediated pathway is largely modified through whole network interactions with other pathways. In this review, we will summarize recent knowledge networks regulate development growth focus shape meristem.
