Study Progress of Intergeneric Hybridization between Chicken and Quail
In the present paper, we reviewed intergeneric hybridization between chicken and quail from four aspects, such as morphology, molecular genetics, sex identification of earlier embryos and prospects, summarized the recent research progress from the scholars at home or abroad, and aimed to attract more and more attention to intergeneric hybridization between chicken and quail, offer more space an...
متن کاملInterspecific and intergeneric hybridization and chromosomal engineering of Brassicaceae crops
In Brassicaceae crop breeding programs, wild relatives have been evaluated as genetic resources to develop new cultivars with biotic and abiotic stress resistance. This has become necessary because of the diversification of ecotypes of diseases and pests, changing food preferences, advances in production technology, the use of new approaches such as in vitro breeding programs, and the need for ...
متن کامل[Genomic in situ hybridization in intergeneric hybrids between Raphanus sativus and Brassica oleracea].
Genomic in situ hybridization (GISH) was applied to study the meiosis of F1 plants from intergeneric hybrids between radish (Raphanus sativus, 2n=18, RR) and cabbage (Brassica oleracea, 2n=18, CC). The result showed that its somatic cells had the expected chromosomes, RC, 2n=18; but the pollen mother cells (PMCs) were different. There were three main kinds of PMCs. The first one was RC (2n=18),...
متن کاملIntergeneric Phylogenetic Relationships of Swallows Estimated by Dna-dna Hybridization
--The phylogeny of the subfamily Hirundininae was estimated by hybridizing single-copy nuclear DNAs of 21 swallow species, representing 19 former and current genera, and a Tufted Titmouse (Parus bicolor) as outgroup. The phylogeny, which was unusually well resolved, consisted of three fundamental clades: Hirundo and allies, core martins, and African sawwings. The clade of Hirundo and allies com...
متن کاملUntangling Nucleotide Diversity and Evolution of the H Genome in Polyploid Hordeum and Elymus Species Based on the Single Copy of Nuclear Gene DMC1
Numerous hybrid and polypoid species are found within the Triticeae. It has been suggested that the H subgenome of allopolyploid Elymus (wheatgrass) species originated from diploid Hordeum (barley) species, but the role of hybridization between polyploid Elymus and Hordeum has not been studied. It is not clear whether gene flow across polyploid Hordeum and Elymus species has occurred following ...
