Abstract

The grain number per panicle is a key agronomic trait of ideal plant architecture in rice (Oryza sativa L.). Here, we characterized and cloned OsNPF4, a member of the NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER (NPF) family that substantially alters rice yield. Overexpression of OsNPF4 significantly increased grain number per panicle but decreased panicle number. OsNPF4 was activated by IDEAL PLANT ARCHITECTURE1 (IPA1) via the SQUAMOSA promoter binding protein-like (SPL) binding sites in its promoter. Additionally, OsNPF4 interacted with DENSE AND ERECT PANICLE1 (DEP1), whose transcription is also induced by IPA1. Our findings indicate that OsNPF4 contributes to establishing ideal plant architecture in rice, and manipulating its expression could help produce elite super rice varieties.
硝态氮转运蛋白1/肽转运蛋白家族4与水稻穗状核蛋白1相互作用,调控水稻粒数
每穗粒数是水稻理想植株结构的关键农艺性状。在这里,我们鉴定并克隆了OsNPF4,它是硝酸盐转运蛋白1/肽转运蛋白(NPF)家族的成员,可以显著改变水稻产量。过表达OsNPF4显著提高每穗粒数,但显著降低穗数。OsNPF4通过其启动子中的SQUAMOSA启动子结合蛋白样(SPL)结合位点被IDEAL PLANT ARCHITECTURE1 (IPA1)激活。此外,OsNPF4与DENSE AND竖立PANICLE1 (DEP1)相互作用,后者的转录也可由IPA1诱导。研究结果表明,OsNPF4有助于水稻理想植株结构的建立,调控其表达有助于培育优质超级稻品种。
