Modelling meristem development in plants.
Meristems continually supply new cells for post-embryonic plant development and coordinate the initiation of new organs, such as leaves and flowers. Meristem function is regulated by a large and interconnected dynamic system that includes transcription networks, intercellular protein signalling, polarized transport of hormones and a constantly changing cellular topology. Mathematical modelling,...
متن کاملShoot Meristem Formation in Vegetative Development.
The majority of the plant body is derived from the activities of groups of specialized cells, known as apical meristems, at the growing tips. In a typical flowering plant, the shoot apical meristem (SAM) gives rise to the bulk of the above-ground portion of the plant, whereas root meristems give rise to the bulk of the subterranean plant body. Of course, not all plants are typical, and numerous...
متن کاملPlant Development: Light Exposure Directs Meristem Fate
Leaf initiation was previously thought to be self-regulated and not reliant on environmental cues. However, a recent study has revealed that light redirects meristem fate from maintenance to lateral organ initiation, through the regulation of the plant hormones auxin and cytokinin.
متن کاملMeristem identity and phyllotaxis in inflorescence development
Inflorescence morphology is incredibly diverse. This diversity of form has been a fruitful source of inquiry for plant morphologists for more than a century. Work in the grasses (Poaceae), the tomato family (Solanaceae), and Arabidopsis thaliana (Brassicaceae) has led to a richer understanding of the molecular genetics underlying this diversity. The character of individual meristems, a combinat...
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-...
