Reaction-Diffusion Pattern in Shoot Apical Meristem of Plants
A fundamental question in developmental biology is how spatial patterns are self-organized from homogeneous structures. In 1952, Turing proposed the reaction-diffusion model in order to explain this issue. Experimental evidence of reaction-diffusion patterns in living organisms was first provided by the pigmentation pattern on the skin of fishes in 1995. However, whether or not this mechanism p...
متن کاملInitiation of shoot apical meristem in rice
In flowering plants, the fundamental body plan is constructed during embryogenesis. The fertilized egg first sets up apicalbasal, radial and dorsal-ventral axes, which are later partitioned to differentiate region-specific organs. The shoot and root apical meristems arise as terminal elements of apical-basal axes. The establishment of shoot apical meristem (SAM) during embryogenesis is a key ev...
متن کاملMicroRNAs in the shoot apical meristem of soybean.
Plant microRNAs (miRNAs) play crucial regulatory roles in various developmental processes. In this study, we characterize the miRNA profile of the shoot apical meristem (SAM) of an important legume crop, soybean, by integrating high-throughput sequencing data with miRNA microarray analysis. A total of 8423 non-redundant sRNAs were obtained from two libraries derived from micro-dissected SAM or ...
متن کاملMetabolic aspects of organogenesis in the shoot apical meristem.
Research over the last decade has led to tremendous advances in the characterization of the transcriptional networks involved in the initiation and maintenance of the shoot apical meristem (SAM), as well as the factors involved in the formation and development of leaves by this organ. However, one aspect of the SAM that has received rather limited attention is the fact that it is characterized ...
متن کاملCellular parameters of the shoot apical meristem in Arabidopsis.
The shoot apical meristem (SAM) is a small group of dividing cells that generate all of the aerial parts of the plant. With the goal of providing a framework for the analysis of Arabidopsis meristems at the cellular level, we performed a detailed morphometric study of actively growing inflorescence apices of the Landsberg erecta and Wassilewskija ecotypes. For this purpose, cell size, spatial d...
