Sequence 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 کاملMapping and Identifying a Candidate Gene (Bnmfs) for Female-Male Sterility through Whole-Genome Resequencing and RNA-Seq in Rapeseed (Brassica napus L.)
In oilseed crops, carpel and stamen development play vital roles in pollination and rapeseed yield, but the genetic mechanisms underlying carpel and stamen development remain unclear. Herein, a male- and female-sterile mutant was obtained in offspring of a (Brassica napus cv. Qingyou 14) × (Qingyou 14 × B. rapa landrace Dahuang) cross. Subsequently, F2-F9 populations were generated through self...
متن کاملErratum: A candidate gene-based association study of tocopherol content and composition in rapeseed (Brassica napus)
Rapeseed (Brassica napus L.) is the most important oil crop of temperate climates. Rapeseed oil contains tocopherols, also known as vitamin E, which is an indispensable nutrient for humans and animals due to its antioxidant and radical scavenging abilities. Moreover, tocopherols are also important for the oxidative stability of vegetable oils. Therefore, seed oil with increased tocopherol conte...
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 کاملIdentification of BnaYUCCA6 as a candidate gene for branch angle in Brassica napus by QTL-seq
Oilseed rape (Brassica napus L.) is one of the most important oil crops in China as well as worldwide. Branch angle as a plant architecture component trait plays an important role for high density planting and yield performance. In this study, bulked segregant analysis (BSA) combined with next generation sequencing technology was used to fine map QTL for branch angle. A major QTL, designated as...
