gw2.1, a new allele of GW2, improves grain weight and grain yield in rice.

Grain weight is an important characteristic of grain shape and a key contributing factor to the grain yield in rice. Here, we report that gw2.1, a new allele of the Grain Width and Weight 2 (GW2) gene, regulates grain size and grain weight.

Diastereoselective Access to Triazolo[1,2-]indolines via a Bio-Inspired Oxidative Cyclization of NH-Indoles.

Establishing three-dimensional chemicals by using the C-C π bond of indoles has always been a research hotspot in organic synthesis; however, employing the oxidative C-C π bond of indoles to generate imine which would lead to the N-C π bond cyclization under metal-free conditions is still rare. Here, we report a bio-inspired synthesis of triazolo[1,2-]indolines by the oxidative cyclization between -indoles and azomethine imines with 3,3-dimethyldioxirane as the sole oxidant under metal-free and mild conditions. This finding represents an elegant instance of tri-functionalization of -indoles, which provides rapid access to a broad range of triazolo[1,2-]indolines with tetrahydroisoquinolines in one single step.

Natural variation of the BRD2 allele affects plant height and grain size in rice.

The zqdm1 identified from a rice mutant is a novel allele of BRD2 and is responsible for regulating rice plant height, grain size and appearance, which has possibilities on improving rice quality. Plant height is an important agronomic trait related to rice yield, and grain size directly determines grain yield in rice (Oryza sativa L.).
