Identification of a new allele of BraA09g066480.3C controlling the wax-less phenotype of Chinese cabbage.

ABSTRACT:

Background

Epidermal wax covers the surfaces of terrestrial plants to resist biotic and abiotic stresses. Wax-less flowering Chinese cabbage (Brassica campestris L. ssp. chinesis var. utilis tsen et lee) has the charateristics of lustrous green leaves and flower stalks, which are of high commercial value.

Results

To clarify the mechanism of the wax deficiency, the wax-less flowering Chinese cabbage doubled-haploid (DH) line 'CX001' and Chinese cabbage DH line 'FT', obtained from isolated microspore culture, were used in the experiments. Genetic analysis showed that the wax-less phenotype of 'CX001' was controlled by a recessive nuclear gene, named wlm1 (wax-less mutation 1), which was fine-mapped on chromosome A09 by bulked segregant analysis sequencing (BSA-seq) of B.rapa g
