Abstract excerpt

The multi-main-stem (MMS) trait presents considerable potential for improving plant architecture and increasing yield in rapeseed (Brassica napus L.). However, the molecular mechanism underlying MMS formation remains poorly understood. In this study, we characterized a dominant MMS material, 1030R. Genetic analysis indicated that the MMS phenotype is controlled by a single dominant gene, designated BnaMMS....
