Control of phyllotaxy in maize by the abphyl1 gene.
Organogenesis in plants occurs at the shoot apical meristem, a group of indeterminate stem cells that are organized during embryogenesis. Regulated initiation of leaves or flowers from the shoot meristem gives rise to the familiar geometric patterns observed throughout the plant kingdom. The mechanism by which these patterns, termed phyllotaxies, are generated, remains unclear. Maize plants ini...
متن کاملClockwise and Counterclockwise Spirality in the Phyllotaxy of Tobacco >
Only two species of tobacco, Nicotiana tabacum L. and N. rustica L., have found an important place in cultivation for chewing or smoking purposes. N, rustica is now of little importance in agriculture, having been supplanted by AT', tabacum except in parts of Poland, Union of Soviet Socialist Republics, Asia Minor, and India. In both of these species the fundamental arrangement of the leaves al...
متن کاملThe ERECTA receptor kinase regulates Arabidopsis shoot apical meristem size, phyllotaxy and floral meristem identity
In plants, the shoot apical meristem (SAM) serves as a reservoir of pluripotent stem cells from which all above ground organs originate. To sustain proper growth, the SAM must maintain homeostasis between the self-renewal of pluripotent stem cells and cell recruitment for lateral organ formation. At the core of the network that regulates this homeostasis in Arabidopsis are the WUSCHEL (WUS) tra...
متن کاملControl of flower development and phyllotaxy by meristem identity genes in antirrhinum.
The flower meristem identity genes floricaula (flo) and squamosa (squa) promote a change in phyllotaxy from spiral to whorled in Antirrhinum. To determine how this might be achieved, we have performed a combination of morphological, genetic, and expression analyses. Comparison of the phenotypes and RNA expression patterns of single and double mutants with the wild type showed that flo and squa ...
