Identification of genes associated with pistil development by transcriptome analysis of a female sterility mutant (fsm) in Chinese cabbage (Brassica campestris ssp. pekinensis)

ABSTRACT: The female sterility mutants are ideal materials for studying the pistil development in plants. We identified a female sterility mutant (fsm) exhibiting stable inheritance, which was derived from a Chinese cabbage DH line ‘FT’ using the combination of isolated microspore culture and ethyl methanesulfonate (EMS) mutagenesis. Genetic analysis indicated that the phenotype of fsm was controlled by a single recessive nuclear gene. The morphological observations revealed that the differences in the floral organs were significant between fsm and its wild type ‘FT’, the pistil of fsm was smaller and shorter, especially the ovary; and the degenerated ovule in the ovary may directly result in the female sterility. Comparative transcriptome analysis of ‘FT’ and fsm were performed using RN
