moricandia moricandioides/infertility

Nuclear-mitochondrial gene interactions governing cytoplasmic male sterility (CMS) in angiosperms have been found to be unique to each system. Fertility restoration of three diverse alloplasmic CMS lines of Brassica juncea by a line carrying the fertility-restorer gene introgressed from Moricandia

KEY MESSAGE: oxa CMS is a new cytoplasmic male sterility type in Brassica juncea. oxa CMS is a cytoplasmic male sterility (CMS) line that has been widely used in the production and cultivation of stem mustard in the southwestern China. In this study, different CMS-type specific mitochondrial markers

Mitochondrial atpA transcripts were examined in cytoplasmic male sterile (CMS) and fertility restorer lines of CMS (Moricandia arvensis) Brassica juncea. Male sterile flowers had longer atpA transcripts than male fertiles. The mitochondrial atpA region of the CMS line was cloned and sequenced. The

Intergeneric somatic hybrids have been produced between Brassica juncea (2n=36, AABB) cv. RLM-198 and Moricandia arvensis (2n=28, MM) by protoplast fusion. Hypocotyl protoplasts of B. juncea were fused with mesophyll protoplasts of M. arvensis using polyethylene glycol. Fusion frequency, estimated

We have developed a cytoplasmic male sterile (CMS) line of Brassica juncea through somatic hybridization with Moricandia arvensis and introgressed the fertility restorer gene into B. juncea. This fertility restorer locus is unique in that it is capable of restoring male fertility to two other

Intergeneric hybridization was performed between Moricandia arvensis and four inbred lines of Brassica rapa following embryo rescue. Three F(1) hybrid plants were developed from three cross combinations of M. arvensis × B. rapa, and amphidiploids were synthesized by colchicine treatment. Six BC(1)
