Canonical Rab5 GTPases Confer Heat‐Stress Resilience to Pollen Germination
Summary statement In Arabidopsis, canonical Rab5 GTPases ARA7 / RHA1 are upregulated by heat, and their loss ( crab5 mutant) impairs pollen germination under heat, while ARA7 overexpression enhances thermotolerance and competitive fertilisation.
