Zucchini yellow mosaic virus (ZYMV; potyviridae) represents a major pathogen of Cucurbitaceae crops. ZYMV resistance in melon PI 414723 is conditioned by dominant allele at the Zym locus. This resistant accession restricts viral spread and does not develop symptoms, but necrosis sometimes develops response to inoculation. In previous studies, has been mapped linkage group II genetic map. presen...
Molecular markers are modern diagnostic tools, which may help breeders to solve practical problems. They facilitate cultivar identification, the determination of genetic similarities among breeding stocks and enable the calculation of polymorphism level, heterozygosity or self-pollination rate. But the main expectation with respect to molecular markers is their potential use in marker-assisted ...
Brassica napus is a globally important oilseed for which little is known about the genetics of drought adaptation. We previously mapped twelve quantitative trait loci (QTL) underlying drought-related traits in a biparental mapping population created from a cross between winter and spring B. napus cultivars. Here we resequence the genomes of the mapping population parents to identify genetic div...
genetic markers are one of the advances which have occured in the genomics era. among genetic markers, molecular markers mainly because of their abundance, are the most widely used them. development of molecular markers has greatly altered genetics and plant breeding. genetic markers indicate the genetic differences between different organs or species. some studies which were conducted during t...
Background: The molecular studies indicate some of the genes in the promoter region itself, will undergo methylation. Methylation of CpG islands in the promoter region of that cause silence or reduced expression of genes involved in cell growth pathways, which are colorectal cancer causing agents. Detection of methylation status can be used as a marker for cancer diagnosis and prediction of dis...
The reeler mutation in mice produces an especially well characterized disorder, with systematically abnormal migration of cerebral cortical neurons. The reeler gene encodes a large protein, termed Reelin, that in the cortex is synthesized and secreted exclusively in the Cajal-Retzius neurons of the cortical marginal zone (D'Arcangelo et al., 1995). In reeler mutant mice, loss of Reelin protein ...
Abstract Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production without using SMG is not economically feasible. However, SMGs are non-essential once an intact transgenic plant has been established. Eli...
Background and Purpose: Hyphal wall protein 1 (HWP1) is an important adhesin which usually is expressed on the germ tube and hyphal surface produced by different Candida species. The hyphal wall protein-coding gene (HWP1) was evaluated as a novel identification and phylogenetic marker in Candida tropicalis, C. orthopsilosis, C. parapsilosis and C. glabrata. Materials and Methods: Initially, fo...
A large number of spores from fruiting bodies can lead to allergic reactions and other problems during the cultivation of edible mushrooms, including Pleurotus eryngii (DC.) Quél. A cultivar harboring a sporulation-deficient (sporeless) mutation would be useful for preventing these problems, but traditional breeding requires extensive time and labor. In this study, using a sporeless P. eryngii ...
Tomato spotted wilt virus (TSWV) is one of the most destructive viral diseases that threaten worldwide tomato (Solanuum lycopersicum L. syn Lycopersicon esculentum Mill.) production. Use of host resistance appears to be the best way to control the disease. Marker assisted selection (MAS) has become very important and useful in the selection of TSWV resistance genes. The objective of this resear...
