SPL7 — Oryza sativa Japonica

Summary

OS05G0530400, designated SPL7 in rice (Oryza sativa Japonica) on chromosome 5, encodes a heat shock transcription factor (HSF) family protein with a conserved HSF-type DNA-binding domain. The product possesses RNA polymerase II cis-regulatory region sequence-specific DNA binding, identical protein binding, and DNA-binding transcription factor activity. SPL7 is associated with cellular response to heat, regulation of transcription by RNA polymerase II, DNA-dependent transcription, and signal transduction. It localises to both the cytoplasm and nucleus. Phenotypic associations link SPL7 to leaf traits and blast disease response. Studies of related genes in other species connect the family to stress-responsive transcriptional regulation, though this is not established for rice SPL7 itself.
