Inflorescence Architecture: The Transition from Branches to Flowers
The shapes of flowers and their organization into branching systems, called inflorescences, dictate much of plant diversity. Recent studies have identified key regulators in this diversity, revealing that the inflorescence architecture of Solanaceous species depends on sequential and temporal expression of the WUSCHEL-RELATED HOMEOBOX (WOX) gene EVERGREEN (EVG)/ COMPOUND INFLORESCENCE (S) and t...
متن کاملInflorescence commitment and architecture in Arabidopsis.
Flowering plants exhibit one of two types of inflorescence architecture: indeterminate, in which the inflorescence grows indefinitely, or determinate, in which a terminal flower is produced. The indeterminate condition is thought to have evolved from the determinate many times, independently. In two mutants in distantly related species, terminal flower 1 in Arabidopsis and centroradialis in Ant...
متن کاملKNAT1 and ERECTA regulate inflorescence architecture in Arabidopsis.
Plant architecture is dictated by morphogenetic factors that specify the number and symmetry of lateral organs as well as their positions relative to the primary axis. Mutants defective in the patterning of leaves and floral organs have provided new insights on the signaling pathways involved, but there is comparatively little information regarding aspects of the patterning of stems, which play...
متن کاملBeyond Arabidopsis. Translational biology meets evolutionary developmental biology.
Developmental processes shape plant morphologies, which constitute important adaptive traits selected for during evolution. Identifying the genes that act in developmental pathways and determining how they are modified during evolution is the focus of the field of evolutionary developmental biology, or evo-devo. Knowledge of genetic pathways in the plant model Arabidopsis serves as the starting...
متن کاملPerspectives on Translational Biology Chlamydomonas and Arabidopsis. A Dynamic Duo
A translational biology perspective on Chlamydomonas and Arabidopsis might be expected to focus on those genes, cellular components, or biological processes found first in Chlamydomonas and subsequently studied in Arabidopsis. There are indeed many such examples. There are also examples that flow from Arabidopsis to Chlamydomonas in terms of initial discovery and subsequent study. However, the ...
