Summary The cultivation of rice varieties with high seed vigour is vital for the direct seeding rice, and molecular basis regulation remains elusive. Here, we cloned a new gene OsHIPL1 , which encodes hedgehog‐interacting protein‐like 1 protein as causal major QTL qSV3 vigour. was mainly localized in plasma membrane nucleus. RNA sequencing (RNA‐seq) revealed that ABA‐related genes were involved rice. higher levels endogenous ABA measured germinating seeds mutants NIL‐ qsv3 line compared to IR26 plants, two up‐regulated biosynthesis ( OsZEP OsNCED4 ) one down‐regulated catabolism OsABA8ox3 . expression abscisic acid‐insensitive 3 OsABI3 ), OsABI4 OsABI5 significantly plants. These results indicate may be through modulating altering OsABIs during germination Meanwhile, found interacted aquaporin OsPIP1;1, then affected water uptake promote germination. Based on analysis single‐nucleotide polymorphism data accessions, identified Hap1 haplotype positively correlated Our findings showed novel insights into mechanism
