How 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 کاملUnderstanding the shoot apical meristem regulation: A study of the phytohormones, auxin and cytokinin, in rice
Auxin and cytokinin regulate different critical processes involved in plant growth and environmental feedbacks. These plant hormones act either synergistically or antagonistically to control the organisation, formation and maintenance of meristem. Meristem cells can be divided to generate new tissues and organs at the locations of plant postembryonic development. The aboveground plant organs ar...
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 کاملAuxin herbicides: current status of mechanism and mode of action.
Synthetic compounds that act like phytohormonal 'superauxins' have been among the most successful herbicides used in agriculture for more than 60 years. These so-called auxin herbicides are more stable in planta than the main natural auxin, indole-3-acetic acid (IAA), and show systemic mobility and selective action, preferentially against dicot weeds in cereal crops. They belong to different ch...
متن کاملSynergistic action of auxin and cytokinin mediates aluminum-induced root growth inhibition in Arabidopsis.
Auxin acts synergistically with cytokinin to control the shoot stem-cell niche, while both hormones act antagonistically to maintain the root meristem. In aluminum (Al) stress-induced root growth inhibition, auxin plays an important role. However, the role of cytokinin in this process is not well understood. In this study, we show that cytokinin enhances root growth inhibition under stress by m...
