| Popis: | By specifying patterns of determinate and indeterminate growth, FLOWERING LOCUS T/SINGLE FLOWER TRUSS (SFT) and TERMINAL FLOWER 1/SELF-PRUNING (SP) regulate plant architecture. Though well characterized in Arabidopsis, the impacts of these genes on the architectures of diverse crops cultivated in different environments, and their potential to enhance crop productivity and management, are less well addressed. Cotton (Gossypium spp.) is naturally a short-day photoperiodic perennial that is now grown primarily as a day-neutral, annual row crop. Different environments and cultivation practices favor specific growth habits to optimize yield, and in cotton, especially in regions that rely heavily on mechanized harvest, the trend has been to more determinate varieties. Identifying and functionally characterizing SFT and SP homologs in cotton uncovered new aspects of how ratios of indeterminate and determinate growth are balanced, and unraveling their genetic networks emphasized how broadly these gene products affect cotton growth habits. |
