Abstract

Seed vigor is a complex trait encompassing seed germination, seedling emergence, growth, seed longevity, and stress tolerance, all are crucial for direct seeding in rice. Here, we report that the AP2/ERF transcription factor OsRAV1 (RELATED TO ABI3 AND VP1) positively regulates seed germination, vigor, and salt tolerance. Additionally, OsRAV1 was differently expressed in embryo and endosperm, with the OsRAV1 localized in the nucleus. Transcriptomic analysis revealed that OsRAV1 modulates seed vigor through plant hormone signal transduction and phenylpropanoid biosynthesis during germination. Haplotype analysis showed that rice varieties carrying Hap3 displayed enhanced salt tolerance during seed germination. These findings suggest that OsRAV1 is a potential target in breeding rice varieties with high seed vigor suitable for direct seeding cultivation.

OsRAV1 在水稻发芽过程中调控种子活力和耐盐性
种子活力是一个复杂的性状,包括种子萌发、出苗、生长、种子寿命和抗逆性,这些都是水稻直播的关键。在此,我们报告了 AP2/ERF 转录因子 OsRAV1(与 ABI3 和 VP1 相关)对种子萌发、活力和耐盐性的正向调节作用。此外,OsRAV1在胚和胚乳中的表达不同,OsRAV1定位于细胞核。转录组分析表明,OsRAV1通过植物激素信号转导和萌发过程中的苯丙类生物合成调节种子活力。单倍型分析表明,携带 Hap3 的水稻品种在种子萌发过程中表现出更强的耐盐性。这些发现表明,OsRAV1 是培育适合直播栽培的高种子活力水稻品种的潜在目标。
