Brassica and Its Close Allies: Cytogenetics and Evolution

TL;DR: Armed with new genetic resources from trigenomic bridges, Brassica breeders will be able to improve yield and broaden adaptation of Brassica crops to meet human demands for food and biofuel, particularly in the face of abiotic constraints caused by climate change.

TL;DR: This review introduces the Brassica crop species and their wild relatives, barriers to interspecific and intergeneric hybridization and methods to overcome them, previous successful and unsuccessful attempts at the use of interspecific hybridization for crop improvement in Brassica, and provides information about resources available to breeders wishing to take advantage of this method.

TL;DR: The marker data and geographic distribution of Groups 1 and 2 were consistent with two independent migrations of B. juncea from its center of origin in the Middle East and neighboring regions along trade routes to western China and northern India, followed by regional adaptation.

TL;DR: It is speculated that the putative candidate male sterility gene orf108 may not be responsible for the CMS observed in Brassica oxyrrhina and Diplotaxis catholica, and the potential coincidence of CMS in alloplasmic lines is proposed.

TL;DR: Although after self-pollination pollen germinated on the stigma and pollen tubes were visible in the style, the pods did not develop properly without in vitro culture, and the hybrids were morphologically intermediate between both fusion parents.

TL;DR: Two Brassica napus--Crambe abyssinica monosomic addition lines were obtained from the F2 progeny of the asymmetric somatic hybrid and are potentially useful for molecular genetic analysis of novel C. abyssInica genes or alleles contributing to traits relevant for oilseed rape (B. napus) breeding.

TL;DR: Both maternal and embryonal control of seed colour are expected to contribute to the black-seeded phenotype of oil Seed Rape, as three B. alboglabra chromosomes in three lines influenced seed colour.

TL;DR: Somatic hybrids between the Brassicaceae species A. thaliana and B. nigra have been produced by fusion of intact A.Thaliana protoplasts with irradiated B. Nigra protoplast, and by PCR- and Southern-analysis the nearly symmetric character of two hybrid lines with an intermediate morphology, and the highly asymmetriccharacter of one line with a B. nigra morphology could be proven.
