Abstract excerpt

Brassica napus is the second most important oil crop worldwide. Number of primary branches (Branch number, BN) and silique number on the main inflorescence (SMI) are key yield-related quantitative traits. Here, we cloned a major QTL, qDB.A09, which simultaneously influences BN and SMI. The causal gene, SHOOT APICAL MERISTEM ENLARGER1 (SAME1), encodes a mutator-like transposase-derived transcription factor and is...
