Other claims from this paper (5)
- Observation FLR1, a FERONIA-like receptor-like kinase, was identified as a vital regulator of rice root development.
- Mechanism In rice, FLR1 governs primary root length by modulating cell division within the root apical meristem.
- Observation An interaction screen identified multiple RALF peptides interacting with FLR1, with OsRALF5 emerging as a key functional ligand.
- Association In FLR1 promoter-edited rice mutants, the co-abundance of OsRALF5 and FLR1 mRNAs correlated strongly and positively with root length.
- Observation In situ hybridization and single-cell transcriptomics showed co-expression of FLR1 and OsRALF5 in the epidermis, cortex and stele of the rice root.
