Auxin Action: Slogging out of the Swamp
How does auxin affect so many different aspects of plant growth and development? Recent evidence from localization of auxin efflux carriers and the effects of auxin on degradation of transcription factors has begun to reveal a possible mechanism for auxin action.
متن کاملThe Mechanism of Auxin Action.
Plant growth hormones are known to produce a number of striking effects on various processes including cell enlargement, root initiation, bud inhibition, etc. It has also been shown that the auxins, and indole-3-acetic acid in particular, participate in some general protoplasmic processes. Support for this view has been most recently afforded in the demonstration by COMMONER and THIMANN (1) tha...
متن کاملMMed cohort supervision: A path out of the swamp?
The authors present the case for collaborative cohort supervision (CCM), including both master's students and novice supervisors, as a possible way to rapidly increase the number of supervisors needed to address the recent implementation of a compulsory research component to specialist registration with the Health Professions Council of South Africa. Different models of CCM are discussed and po...
متن کاملMolecular mechanisms of auxin action.
The plant growth hormone auxin has an important role in a variety of plant growth and developmental processes. Identification of transcription factors, some with defined genetic function, has shed new light on the mechanisms of auxin regulated gene expression. In addition, the molecular characterization of genes required for auxin response indicates that regulated protein degradation by the ubi...
متن کاملEarly genes and auxin action.
The plant hormone IAA (or auxin) is central to the control of plant growth and development. Processes governed by auxin in concert with other plant growth regulators include development of vascular tissues, formation of lateral and adventitious roots, control of apical dominance, and tropic responses (Went and Thimann, 1937). At the leve1 of cellular physiology, auxin profoundly affects turgor,...
