This article, published in the Journal of Experimental Botany, explores the role of a DEAD-box RNA helicase called OsRH52A in the development of the female gametophyte and seed setting in rice. The study found that loss of OsRH52A led to abnormal development of the embryo sac, resulting in low seed setting. The article also discusses the importance of normal development of male and female gametophytes for successful fertilization and seed production, as well as the various factors that can cause degeneration or defects in these gametophytes. The study highlights the molecular pathway of embryo sac development and suggests potential interactions with other proteins involved in reproductive development. Additionally, the article discusses the impact of OsRH52A on the expression of downstream genes involved in megaspore development. Overall, this research provides insights into the mechanisms underlying fertility in plants and has implications for hybrid rice development. [Extracted from the article]
