Gene expression in cauliflower curds

Description of gene expression in various types of cauliflower (including Romanesco type) Cauliflower structures develop on inflorescences from plants such as the apetala1 cauliflower double mutant in Arabidopsis thaliana or in the edible Brassica oleracea var botrytis or Romanesco. Whereas the genetic basis for the development of such structure is well understood in the model plant Arabidopsis thaliana, it is less understood in Brassica oleracea. In order to gain insight into the gene expression present in cauliflower and Romanesco curds, we performed RNA-seq analyses of mature cauliflowers and Romanesco curds and from growing cauliflowers curds. This analysis allowed to establish the nature of genes from the APETALA1 and CAULIFLOWER clade that are either mutated or expressed at very low levels in curd structures. These results shed light on the molecular nature of structures that have been selected in the domestication process. Overall design: Cauliflower were harvested from field experiments or bought at producer and RNA-seq was performed on curd sample
