What is it about?
Seed setting rate is an important agronomic trait that directly determines grain yield in rice. Here we report a novel gene, called DPS1, that is required for seed setting in rice by regulating panicle and anther cuticle development. It can greatly contribute to breeding for high yielding rice cultivars.

Why is it important?
Panicle fertility and anther development are important traits of interest for plant breeders to understand the mechanism of male reproduction in plants. Cuticle is a key protective covering and a semi permeable membrane that control the movement of water and nutrients across anthers. It plays significant role for the development of normal pollen grains inside anther locules. This study helped to improve our understanding of the mechanism of anther cuticle development and the role of reactive oxygen species (ROS) in regulating panicle and anther development. This is the first study to report the ROS-mediated regulation of anther cuticle development.
Perspectives
Overaccumualtion of ROS is the key player in panicle degeneration in rice. This article explained how ROS is overaccumulated.
