The role of OsRGA1 in aerenchyma formation and adventitious root growth in rice seedlings based on the U-Gompertz model.

ABSTRACT:

Background

Aerenchyma in adventitious roots plays a crucial role in rice growth under flooding conditions. However, the mechanisms underlying the dynamic formation process of aerenchyma remain poorly understood, largely due to the time-consuming and labor-intensive nature of traditional sectioning methods for analyzing aerenchyma formation. In this study, we optimized the Gompertz model to investigate the dynamic process of aerenchyma formation and its relationship with root growth. The materials used included the wild-type Nipponbare (NIP) as well as OsRGA1 knockout and overexpression lines, rga1-5 and RGA1-OE1.

Results

All three parameters of the optimized U-Gompertz model directly characterized the dynamic process of aerenchyma formation. Compared to NIP, the rga1-5 knock
