The accomplishment of further optimization of crop productivity in grain yield and quality is a
great challenge. Grain size is one of the crucial determinants of rice yield and quality; all of …

Grain appearance, one of the key determinants of rice quality, reflects the ability to attract
consumers, and is characterized by four major properties: grain shape, chalkiness …

The persistent triploid endosperms of cereal crops are the most important source of human
food and animal feed. The development of cereal endosperms progresses through …

Cold stress affects rice growth and productivity. Defects in the plastid-localized
pseudouridine synthase OsPUS1 affect chloroplast ribosome biogenesis, leading to low …

Pentatricopeptide repeat (PPR) proteins constitute one of the largest protein families in land
plants, with over 300 members in various species. Nearly all PPR proteins are nuclear …

With rising living standards, there is an increasing demand for high-quality rice. Rice quality
is mainly defined by milling quality, appearance quality, cooking and eating quality, and …

Lesion mimic mutants are used to elucidate mechanisms controlling plant responses to
pathogen attacks and environmental stresses. Although dozens of genes had been …

Key message OsPPR11 belongs to the P-type PPR protein family and can interact with
OsCAF2 to regulate Group II intron splicing and affect chloroplast development in rice …

Starch is a major component of cereals, comprising over 70% of dry weight. It serves as a
primary carbon source for humans and animals. In addition, starch is an indispensable …

Key message P-subfamily PPR protein OsPPR939, which can be phosphorylated by
OsS6K1, regulates plant growth and pollen development by involving in the splicing of …
