Annotated Information
Function
- Hwi1 and Hwi2 are likely to determine the high temperature-dependent expression of hybrid weakness in interspecific hybrids of rice.
- Hwi1 comprises two leucine-rich repeat receptor-like kinase (LRR–RLK) genes, 25L1 and 25L2, which are specific to wild rice (Oryza rufipogon) and induce hybrid weakness.
- Functional analysis indicated that pyramiding of Hwi1 and Hwi2 activates the autoimmune response in the basal nodes of hybrids, interrupting root formation and then impairing shoot growth.
