  • Patent number: 8030548
    Abstract: A cytoplasmic male sterility (CMS) system in different Brassica species having a distinct mitochondrial DNA specific RFLP signature. A method for obtaining male sterile lines and restoration of fertility in B. juncea for hybrid seed production using the CMS. This CMS in B. juncea can be restored by crossing male sterile plants with any B. juncea genotype other than the maintainer genotype. The same B. juncea genotype acts as maintainer of male sterility after a specified number of backcrosses. The CMS also relates to histological characterization of another and microspore development in B. juncea.

  • Patent number: 7741541
    Abstract: A method for obtaining improved fertility restorer lines for male sterile crop plants and a DNA construct for use in said method are disclosed. The invention relates to the simultaneous use of two different gene sequences encoding the same protein product, one being the naturally occurring wild type sequence and the other sequence being generated by modification of the wild type sequence for expression in crop plants by using codon degeneracy to avoid homology between the two sequences at the DNA and mRNA levels, each of the said sequences being placed under independent transcriptional control of different overlapping plant tissue-specific regulatory elements in the same DNA construct.

  • Publication number: 20080148429
    Abstract: The present invention relates to a novel cytoplasmic male sterility (CMS) ‘126-1’ system in different Brassica species and a method for obtaining male sterile lines using the said CMS. The CMS has distinct mitochondrial DNA specific RFLP signature. The invention also relates to a method for obtaining male sterile lines and restoration of fertility in B. juncea for hybrid seed production. This CMS in B. juncea can be restored by crossing male sterile plants with any B. juncea genotype other than the maintainer genotype. The same B. juncea genotype acts as maintainer of male sterility after a specified number of backcrosses. This invention also relates to the histological characterization of anther and microspore development in B. juncea.
