The Role of Auxin-Cytokinin Antagonism in Plant-Pathogen Interactions
It has been several decades since Skoog and Miller described the contrasting behavior of auxin and cytokinin in promoting the growth of root and shoot, respectively [1]. In recent years, a lot of progress has been made in understanding the regulation of stem cell niche and cell fate in both shoot and root apical meristems. Developmental processes such as the maintenance of root meristems [2], l...
متن کاملHow Auxin and Cytokinin Phytohormones Modulate Root Microbe Interactions
A large range of microorganisms can associate with plants, resulting in neutral, friendly or hostile interactions. The ability of plants to recognize compatible and incompatible microorganisms and to limit or promote their colonization is therefore crucial for their survival. Elaborated communication networks determine the degree of association between the host plant and the invading microorgan...
متن کاملCytokinin regulation of auxin synthesis in Arabidopsis involves a homeostatic feedback loop regulated via auxin and cytokinin signal transduction.
Together, auxin and cytokinin regulate many of the processes that are critical to plant growth, development, and environmental responsiveness. We have previously shown that exogenous auxin regulates cytokinin biosynthesis in Arabidopsis thaliana. In this work, we show that, conversely, the application or induced ectopic biosynthesis of cytokinin leads to a rapid increase in auxin biosynthesis i...
متن کاملA Shortcut to Activity-Dependent Transcription
Neuronal activity results in the rapid induction of gene transcription through a series of defined molecular events. Madabhushi et al. describe an unexpected role for the cutting of promoter DNA by topoisomerase IIB to facilitate transcription of activity-induced genes.
متن کاملAuxin–Cytokinin Interaction Regulates Meristem Development
Plant hormones regulate many aspects of plant growth and development. Both auxin and cytokinin have been known for a long time to act either synergistically or antagonistically to control several significant developmental processes, such as the formation and maintenance of meristem. Over the past few years, exciting progress has been made to reveal the molecular mechanisms underlying the auxin-...
