Food is a fundamental human right, and global food security threatened by crop production. Plant growth regulators (PGRs) play an essential role in improving yield quality, this study reports on novel PGR, termed guvermectin (GV), isolated from plant growth-promoting rhizobacteria, which can promote root coleoptile growth, tillering, early maturing rice. GV nucleoside analogue like cytokinin (CK), but it was found that significantly promoted hypocotyl different the function of CK...

Summary Traditional rice blast resistance breeding largely depends on utilizing typical ( R ) genes. However, the lack of durable genes has prompted breeders to find new resources. Susceptibility S are potential targets for genetic engineering using genome‐editing technologies, but identifying them is still challenging. Here, through integration genome‐wide association study (GWAS) and transcriptional analysis, we identified two genes, RNG1 RNG3 , whose polymorphisms in 3′‐untranslated...

Rice leaf width (RLW) is a crucial determinant of photosynthetic area. Despite the discovery several genes controlling RLW, underlying genetic architecture remains unclear. In order to better understand this study conducted genome-wide association (GWAS) on 351 accessions from rice diversity population II (RDP-II). The results revealed 12 loci associated with (LALW). LALW4, we identified one gene, Narrow Leaf 22 (NAL22), whose polymorphisms and expression levels were RLW variation. Knocking...
