Wheat seed development is a critical process to determining wheat yield and quality, which is controlled by genetics, epigenetics and environments. The N6-methyladenosine (m6A) modification is a reversible and dynamic process and plays regulatory role in plant development and stress responses. To better understand the role of m6A in wheat grain development, we characterized the m6A modification at 10 days post-anthesis (DPA), 20 DPA and 30 DPA in wheat grain development.

小麦籽粒发育是决定小麦产量与品质的核心过程，其受遗传、表观遗传及环境因素共同调控。N6-甲基腺苷（N6-methyladenosine，m6A）修饰是一种可逆且动态的生物学过程，在植物发育与胁迫应答中发挥关键调控作用。为深入解析m6A修饰在小麦籽粒发育中的功能，本研究对小麦籽粒发育至扬花后10天（days post-anthesis，DPA）、20 DPA及30 DPA三个时期的m6A修饰特征进行了系统表征。
