LAX1, functioning with MADS-box genes, determines normal palea development in rice.

Normal floral organ development in rice is necessary for grain formation. Many MADS-box family genes that belong to ABCDE model have been widely implicated in rice flower development. The LAX1 allele encodes a plant-specific basic helix-loop-helix (bHLH) transcription factor, which is the main regulator of axillary meristem formation in rice.

Favorable Alleles of Increase the Grain-Filling Rate and Yield of Rice.

Hybrid rice () has been cultivated commercially for 42 years in China. However, poor grain filling still limits the development of hybrid rice. We report here the map-based cloning and characterization of the () gene present at a major-effect quantitative trait locus.

Favorable Marker Alleles for Panicle Exsertion Length in Rice ( L.) Mined by Association Mapping and the RSTEP-LRT Method.

The panicle exsertion length (PEL) in rice ( L.) is an important trait for hybrid seed production. We investigated the PEL in a chromosome segment substitution line (CSSL) population consisting of 66 lines and a natural population composed of 540 varieties.

Identification of a Candidate Gene for Panicle Length in Rice (Oryza sativa L.) Via Association and Linkage Analysis.

Panicle length (PL) is an important trait for improving panicle architecture and grain yield in rice (Oryza sativa L.). Three populations were used to identify QTLs and candidate genes associated with PL.
