Insect pests can reduce wheat yield by direct feeding and transmission of plant viruses. Here we report results from laboratory and field phenotyping studies on a wide range of wheat, including landraces from the Watkins collection deriving from before the green revolution, more modern cultivars from the Gediflux collection (north-western Europe) and modern UK Elite varieties, for resistance to...

Three sets of hexaploid introgressive triticale lines, with Triticum monococcum ssp. monococcum (cultivated einkorn wheat) genes and a bread wheat chromosome 1D substituted for chromosome 1A, and one set of secondary triticale lines were evaluated for grain and flour physicochemical and dough rheological characteristics in two generations (F7 and F8). Genomic in situ hybridization (GISH) and fl...

Tan spot, one of the most important diseases of wheat, is caused by Pyrenophora tritici-repentis, a necrotrophic fungus which survives in wheat straw. Methods of disease control include fungicide application, crop rotation, and the use of resistant cultivars; however, in Brazil there are no cultivars in the market with a good level of resistance. In North America, a system of race identificatio...

The dynamics of rye chromosomes during mitosis and meiosis was analyzed in a subset comprising 33 F3 lines from the cross of wheat, Psathyrostachys huashanica amphiploid (AABBDDNsNs) and hexaploid triticale (AABBRR), as visualized by genomic in situ hybridization. The results indicated that 31 of the total lines contained 4-14 rye chromosomes. Twenty-eight combinations had more rye chromosomes ...

Following the emergence of the Ug99 lineage of Puccinia graminis f. sp. tritici (Pgt) a collective international effort has been undertaken to identify new sources of wheat stem rust resistance effective against these races. Analyses were undertaken in a collection of wheat genotypes gathered from across Africa to identify stem rust resistance effective against the Pgt races found in Eastern an...

Abstract Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup most crops. Narrowed these crops has made them vulnerable towards disease insect epidemics. For sustainable crop production, variability must be broadened against various biotic abiotic stresses. One ways to widen configuration is identify novel additio...

Objective(s): Valproic acid (VPA) has proven to be as one of the most promising useful drug with anticancer properties.In this study, we investigate the VPA effects on E-cadherin expression in HeLa, TC1, MKN45, and HCT116 cell lines.  This study assesses the effects of VPA on human papillomavirus E7 expression in HPV positive cell lines. Materials and Methods: Cell lines were treated by2 mmol/...
