Cytogenetics and immature embryo culture at Embrapa Trigo breeding program: transfer of disease resistance from related species by artificial resynthesis of hexaploid wheat (Triticum aestivum L. em. Thell)

Genetics and Molecular Biology, 2000
Worldwide wheat (Triticum aestivum L. em. Thell, 2n = 6X = 42, AABBDD) breeding programs aim to reorganize genotypes to achieve better yields, environmental adaptation and food quality.

Duplicate Gene Revolution, Homoeologous Recombination, and Transcriptome Characterization in Allopolyploid Cotton [PDF]

, 2012
Modern allotetraploid cotton contains an “A” and “D” genome from an ancestral polyploidy event that occurred approximately 1–2 million years ago. Diploid A- and D-genome species can be compared to the A- and D-genomes found within these allotetraploids ...

Eyespot resistance gene Pch-1 in H-93 wheat lines. Evidence of linkage to markers of chromosome group 7 and resolution from the endopeptídase locus Ep-Dlb [PDF]

, 1992
Gene Pch1, which confers resistance to eyespot disease (Pseudocercosporella herpotrichoides Fron), has been located on chromosome 7D in the H-93 wheat-Aegilops ventricosa transfer lines using isozyme markers and DNA probes corresponding to group 7 ...

Global analysis of the sugarcane microtranscriptome reveals a unique composition of small RNAs associated with axillary bud outgrowth [PDF]

, 2013
Axillary bud outgrowth determines shoot architecture and is under the control of endogenous hormones and a fine-tuned gene-expression network, which probably includes small RNAs (sRNAs).

The CACTA transposon Bot1 played a major role in Brassica genome divergence and gene proliferation [PDF]

, 2008
We isolated and characterized a Brassica C genome-specific CACTA element, which was designated Bot1 (Brassica oleracea transposon 1). After analysing phylogenetic relationships, copy numbers and sequence similarity of Bot1 and Bot1 analogues in B ...

Transfer of resistance to eyespot disease from Aegilops ventricosa to wheat [PDF]

, 1984
The extraspecific transfer of genes into cultivated plants is of considerable interest both in basic and applied terms (Sears, 1956; Riley and Kimber 1966).

Exploiting phKL-mediated homoeologous recombinants to map stripe rust resistance gene YrAev from Aegilops variabilis

Crop Journal
Aegilops variabilis (SvSvUvUv) is a source of resistance to wheat stripe rust. The phKL locus in Chinese common wheat landrace Kaixian-Luohanmai (KL) can induce homoeologous wheat-alien chromosome pairing and recombination.

MATHEMATICAL COMPARISON OF HOMOLOGOUS AND HOMOEOLOGOUS CHROMOSOME CONFIGURATIONS AND THE MODE OF ACTION OF THE GENES REGULATING PAIRING IN WHEAT [PDF]

Genetics, 1979
ABSTRACT Analyses of frequencies of chromosome configurations in wheat and wheat hybrids are extended to include data from hybrids of three chromosome-pairing mutants of wheat with Aegilops variabilis and from autotetraploid Triticum monococcum.

Inheritance of Resistance to Pea Mosaic Virus in Pisum sativum [PDF]

, 2017
The high level of resistance to pea mosaic virus in the pea cultivar Bonneville is conferred by a single recessive gene. This factor, tentatively designated Pmv, is closely linked to mo, cyv, and sbm-2, which confer resistance to bean yellow mosaic virus,

Cytogenetic features of intergeneric amphydiploids and genome-substituted forms of wheat

Вавиловский журнал генетики и селекции
Synthetic intergeneric amphydiploids and genome-substituted wheat forms are an important source for transferring agronomically valuable genes from wild species into the common wheat (Triticum aestivum L.) genome.
