This study reports the identification of the rice open reading frame Semi-Dwarf in chr8 (SD8) that encodes a putative ortholog of Arabidopsis thaliana ABCB1. Genome editing of SD8 leads to optimized rice architecture by reducing plant height and flag-leaf angle without yield penalty. Rice SD8 knockouts may also have the potential for increased yield under high density planting.
本研究报告了在水稻第 8 号染色体上发现的一个开放阅读框 Semi-Dwarf（SD8），该基因编码拟南芥 ABCB1 的一个假定同源物。通过降低株高和旗叶角度，对 SD8 进行基因组编辑可优化水稻株型，而不会降低产量。在高密度种植条件下，水稻 SD8 敲除突变体也可能具有提高产量的潜力。
