Shoot and inflorescence branching.
A major aspect of postembryonic plant development is the formation of secondary axes of growth: vegetative branches, inflorescence branches, or flowers. The first step in side-shoot development is the establishment of lateral meristems in the axils of leaves. GRAS-, MYB-, and bHLH-type transcription factors act as key regulators of early steps in this process. The REVOLUTA subfamily of HD-ZIP t...
متن کاملMultiple pathways regulate shoot branching
Shoot branching patterns result from the spatio-temporal regulation of axillary bud outgrowth. Numerous endogenous, developmental and environmental factors are integrated at the bud and plant levels to determine numbers of growing shoots. Multiple pathways that converge to common integrators are most probably involved. We propose several pathways involving not only the classical hormones auxin,...
متن کاملInferring the Gene Network Underlying the Branching of Tomato Inflorescence
The architecture of tomato inflorescence strongly affects flower production and subsequent crop yield. To understand the genetic activities involved, insight into the underlying network of genes that initiate and control the sympodial growth in the tomato is essential. In this paper, we show how the structure of this network can be derived from available data of the expressions of the involved ...
متن کاملMorphogenesis at the inflorescence shoot apex of Anagallis arvensis: surface geometry and growth in comparison with the vegetative shoot
Quantitative analysis of geometry and surface growth based on the sequential replica method is used to compare morphogenesis at the shoot apex of Anagallis arvensis in the reproductive and vegetative phases of development. Formation of three types of lateral organs takes place at the Anagallis shoot apical meristem (SAM): vegetative leaf primordia are formed during the vegetative phase and leaf...
متن کاملLAX and SPA: major regulators of shoot branching in rice.
The aerial architecture of plants is determined primarily by the pattern of shoot branching. Although shoot apical meristem initiation during embryogenesis has been extensively studied by molecular genetic approaches using Arabidopsis, little is known about the genetic mechanisms controlling axillary meristem initiation, mainly because of the insufficient number of mutants that specifically alt...
