BUSAN, South Korea, Aug. 11, 2023 /PRNewswire/ -- Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant's stigma, hydrate, and germinate into pollen tubes. Thus, pollen tube germination and elongation are crucial for double fertilization, which, in turn, influences the grain yield of crop plants.
Key Points:
- Thus, pollen tube germination and elongation are crucial for double fertilization, which, in turn, influences the grain yield of crop plants.
- Studies have shown that RALFs play an important role in pollen tube growth.
- D. student Eui-Jung Kim from Kyung Hee University, has identified and characterized two RALF peptides in rice (Oryza sativa).
- In addition, the effect seemed to be dose-dependent because the OsRALFs inhibited pollen tube germination and growth at higher concentrations.
