Alternatively spliced BobCAL transcripts alter curd morphotypes in a collection of Chinese cauliflower accessions.

ABSTRACT: The curd of cauliflower (Brassica oleracea L. var. botrytis) is a modified inflorescence that is consumed as a vegetable. Curd formation is proposed to be due to a mutation in the BobCAULIFLOWER (BobCAL) gene, but the genetic relationship between BobCAL variation and curd morphotypes remains obscure. To address this question, we collected and classified a collection of 78 cauliflower accessions into four subpopulations according to curd surface features: smooth, coarse, granular, and hairy curd morphotypes. Through the cDNA sequencing of BobCAL alleles, we showed that smooth and coarse accessions characterized by inflorescence meristem arrest presented a strong association with the 451T SNP (BobCAL_T), whereas granular and hairy accessions m
