一种敲除ZmABKHL10B-1基因在创制不同光周期环境下稳定提前开花玉米的应用
By knocking out the ZmABKHL10B-1 gene in maize, the CRISPR/Cas9 system was used to promote earlier flowering of maize under different photoperiods, solving the problem of delayed regulation of maize flowering time and achieving stable regulation of flowering time under different photoperiods, thereby improving the adaptability and yield of maize.

AI Technical Summary
In the current technology, research on genes regulating maize flowering period is lagging behind, especially the lack of regulatory genes that are not affected by photoperiod signals. This makes it difficult to stably regulate maize flowering period under different photoperiod conditions, affecting yield and adaptability.
By knocking out the ZmABKHL10B-1 gene in maize, the CRISPR/Cas9 system was used to promote early flowering of maize under different photoperiods. Gene editing was performed using sgRNA composition and recombinant vector to suppress or reduce the expression of the ZmABKHL10B-1 gene.
Under different photoperiod conditions, it significantly promotes earlier flowering of maize, improves adaptability, reduces the impact of extreme weather, ensures crop rotation, shortens the growth period, and increases yield.
