Transcriptome Analysis Reveals Candidate Genes Associated with Leaf Etiolation of a Cytoplasmic Male Sterility Line in Chinese Cabbage (Brassica Rapa L. ssp. Pekinensis).
Cytoplasmic male sterility (CMS) is universally utilized in cruciferous vegetables. However, the Chinese cabbage hau CMS lines, obtained by interspecific hybridization and multiple backcrosses of the Brassica juncea (B. juncea) CMS line and Chinese cabbage, show obvious leaf etiolation, and the molecular mechanism of etiolation remains elusive. Here, the ultrastructural and phenotypic features ...
متن کاملSequence analysis and expression of orf224 gene associated with two types of cytoplasmic male sterility in Brassica napus L.
Polima and Shaan 2A are the two most widely used forms of cytoplasmic male sterility (CMS) in the utilization of heterosis of rapeseed (Brassica napus) in China. A previous study indicated that the mitochondrial gene, orf224, was the only gene with a differential expression pattern among the normal, sterile and fertility-restored lines in rapeseed. DNA sequences of orf224, including coding sequ...
متن کاملCytoplasmic male sterility in Brassicaceae crops
Brassicaceae crops display strong hybrid vigor, and have long been subject to F1 hybrid breeding. Because the most reliable system of F1 seed production is based on cytoplasmic male sterility (CMS), various types of CMS have been developed and adopted in practice to breed Brassicaceae oil seed and vegetable crops. CMS is a maternally inherited trait encoded in the mitochondrial genome, and the ...
متن کاملRNA editing of transcripts of a chimeric mitochondrial gene associated with cytoplasmic male-sterility in Brassica.
The orf224 gene is a chimeric open reading frame associated with the Polima or pol cytoplasmic male sterility of Brassica napus. The first 58 codons and 5' upstream region of orf224 are derived from a conventional mitochondrial gene, orfB, while the origin of the remaining portion of the gene is unknown. Transcripts of the orf224 gene were found to be edited at a single site in the region of th...
متن کاملDirectional transfer of a multiple-allele male sterile line in Brassica campestris L. ssp. chinensis (L.) Makino var. rosularis Tsen et Lee
To produce hybrid seeds of Wutacai (Brassica campestris L. ssp. chinensis (L.) Makino var. rosularis Tsen et Lee), a "directional transfer program" was designed to breed the multiple-allele male sterile line of Wutacai. A multiple-allele male sterile line of Naibaicai (Brassica campestris L. ssp. chinensis L., S01) was used as the male sterile resource, and an inbred line of Wutacai (WT01) was ...
