Research progress on non-specific lipid transfer proteins in rice

Rice (Oryza sativa) is one of the main grain crops in China. Its yield and quality are of great strategic significance to national food security. Non-specific lipid transfer proteins (nsLTPs) are small molecule secretory proteins, which are widely distributed in cells. They promote lipid transport in plants by participating in the non-vesicular transport process of lipids. In recent years, they have been widely studied in rice. nsLTPs are closely related to the growth, development, and stress resistance of rice. They are involved in multiple physiological processes such as lipid secretion, signal transduction, anther development, seed development, and pathogen defense. In this paper, we introduced the structural characteristics, classification, and basic functions of nsLTPs in rice growth and development, as well as their roles in resisting abiotic stresses and biotic stresses, such as drought stress, low temperature stress, salt stress, rice blast disease, brown planthoppers and rice stem borers. It has important reference value for understanding the role of nsLTPs in rice.
