- Abstract:
- ... Freezing tolerance and winter hardiness are complex traits. In the Triticeae, two loci on the group 5 chromosome homoeologs are repeatedly identified as having major effects on these traits. Recently, we found that segments of the genomic region at one of these loci, Frost resistance-2 (Fr-2) is copy number variable in barley. Freezing-tolerant winter-hardy genotypes have greater tandem copy numbe ...

- Abstract:
- ... To facilitate isolation and characterization of disease and insect resistance genes important to potato, two bacterial artificial chromosome (BAC) libraries were constructed from genomic DNA of the Mexican wild diploid species, Solanum pinnatisectum, which carries high levels of resistance to the most important potato pathogen and pest, the late blight and the Colorado potato beetle (CPB). One of ...

- Abstract:
- ... Tested haploid embryogenic lines (n=12) of Larix dedicua Mill. initiated from megagametophyte tissue were maintained on half-strength LM medium without growth regulators. The cultures were analyzed for ploidy level after 1-9 years. All lines tested were found to have doubled (2n=24) their chromosome number at the end of the experiment, though there were a few lines that still gave occasional haplo ...

- Abstract:
- ... Self-incompatible diploid potatoes were altered to self-compatible ones by a function of S-locus inhibitor gene and continued selfing generated highly homozygous inbreds. In this study, this process was investigated for the status of DNA methylation by a simple method using genomic DNA digested by methylation-sensitive restriction enzymes prior to RAPD analysis. We detected 31 methylation-sensitiv ...

The three subgenomes of hexaploid bread wheat originated from Triticum urartu (AᵘAᵘ), from a species similar to Aegilops speltoides (SS) (progenitor of the B genome), and from Ae. tauschii (DD). Earlier stu ...

- Abstract:
- ... Red clover is a hermaphroditic allogamous diploid (2n = 2x = 14) with a homomorphic gametophytic self-incompatibility (GSI) system (Trifolium pratense L.). Red clover GSI has long been studied, and it is thought that the genetic control of GSI constitutes a single locus. Although GSI genes have been identified in other species, the genomic location of the red clover GSI-locus remains unknown. The ...

The gene is distinct from previously identified-resistance genes. We have identified and characterised a broad-spectrum resistance to Phytophthora infestans from the wild Mexican species Solanum verrucosum. Diagnostic resistance gene enrichment (dRenSeq) revealed that t ...

This information was used to gain new insights into phylogenetic relationships among species in the genus Oryza. Seven mitochondrial and five chloroplast SSR loci equal to or longer than ten mononucleotide repeats were chosen from known ric ...

- Abstract:
- ... Wheat polyphenol oxidase (PPO) is the major cause of browning reactions that discolor Asian noodles and other wheat products. It has been hypothesized that genes encoding wheat PPOs may have evolved by gene duplication into a multigene family. Here we characterized PPO genomic sequences from diploid (Triticum monococcum, T. urartu, Aegilops tauschii, and Ae. speltoides), tetraploid (T. turgidum, s ...

Developing a better understanding of associations among ploidy level, geographic distribution, and genetic diversity of Cynodon accessions could be beneficial to bermudagrass breeding programs, and would enhance our understanding of the evolutionary biology of this warm season grass species.

This new procedure facilitates a seamless flow of variation across Brassica digenomics. Brassica digenomics, artificially resynthesized by hybridizing extant genome donor diploids, show poor breeding value due to the linkage drag associ ...

These applications usually require genotyping of thousands of SNPs in a large number of individuals. Although a number of SNP genotyping assays are available, most of them are designed for SNP genotyping in diploid individuals. Here, we demonstrate tha ...
