Article Synopsis
- Flowering plants use specific interactions between pollen and pistils to ensure fertilization occurs within the same species and to prevent cross-species fertilization.
- In Arabidopsis, several receptor kinases (RKs) are known to control the later stages of pollen tube growth, but this study investigates their role in the earlier stages.
- The research found that a group of LRR-MAL RKs in the stigma helps support the growth of Arabidopsis pollen tubes and creates a barrier against pollen from other species (like Capsella rubella), highlighting their importance in early sexual reproduction.
Successful fertilization of a flowering plant requires tightly controlled cell-to-cell communication between the male pollen grain and the female pistil. Throughout pollen-pistil interactions, ligand-receptor kinase signaling is utilized to mediate various checkpoints to promote compatible interactions. In , the later stages of pollen tube growth, ovular guidance and reception in the pistil have been intensively studied, and thus the receptor kinases and the respective ligands in these stages are quite well understood.
