Gene Editing Reduces Branch Angle and Altered Petiole Angles in Cotton
January 31, 2024| |
A study published in Frontiers in Plant Science shows that the loss of TAC1 homeologous genes in cotton reduces branch angle and altered petiole angles. The results of this study provide significant insights into understanding optimal light interception in cotton, which can potentially improve crop yield.
Various environmental factors, such as light capture, carbon assimilation, and photosynthetic efficiency, affect crop performance. Previous studies show that controlling branching and plant-to-plant interference improves planting density, photosynthesis and carbon assimilation, and boosts yield. In cotton plants, uneven light distribution within the branch canopy significantly affects its growth, productivity, and yield.
Hence, the researchers from Clemson University and partners have utilized CRISPR-Cas9 technology and Agrobacterium-mediated transformation to silence specific Tiller Angle Control (TAC1) gene homeologs in the stem of cotton plants. The findings of this study accelerate the research on developing commercial cotton varieties with increased crop productivity.
