Abstract excerpt
Genotype-dependent regeneration efficiency remains a major obstacle in wheat transformation, limiting its use in elite but recalcitrant cultivars. To elucidate the molecular basis of regeneration divergence, we compare transcriptomic profiles, chromatin accessibility dynamics, and transcriptional regulatory networks (TRNs) between the regenerable variety Fielder and the recalcitrant variety JiMai22 (JM22)....
