Overview

Uncovers how OsMATE16 affects seed setting in rice under heat stress, suggesting avenues for crop improvement.

Key Points

  • To investigate the role of OsMATE16 in regulating anther dehiscence and seed setting under high temperature conditions.
  • Identified OsMATE16's response to heat stress
  • Analyzed seed setting rates in knockout mutants
  • Measured phytohormone levels in anthers
  • Compared thermotolerance between rice cultivars
  • OsMATE16 knockout mutants showed reduced seed setting rates compared to wild types under heat stress
  • Defective anther dehiscence was observed in OsMATE16 knockout mutants
  • IAA levels were significantly higher in OsMATE16 knockout mutants
  • The OsMATE16Hap3 cultivar exhibited greater thermotolerance than OsMATE16Hap1
