The interaction between temperature and diet quality can affect the life history of ectotherms. The rate and ratio at which protein and carbohydrate are obtained from food are important aspects of diet quality, and insects have a well-developed capacity to adjust their feeding behaviour and post-ingestive physiology to regulate intake and allocation of these nutrients. If the supply of protein ...

El Estado de Guanajuato es el principal productor trigo (Triticum aestivum L.) la región Bajío que segunda zona productora este cereal en México. En ciclo otoño-invierno (OI)1998-99 se sembraron 98 072 ha trigo, con una producción 510 894 t, logr´ó gran medida satisfacer demanda regional. Sin embargo, siembran predominantemente variedades gluten débil y poco fuerte (3900 1999-00), cuya por indu...

The simplified AFLP method was developed and evaluated for identification and genetic diversity studies of wheat cultivars. Selective primers exploited in AFLP assay based on a single cutting enzyme PstI ((PstI)AFLP) generated total of 111 robust fragments, including 67 (60%) monomorphic and 12 (11%) cultivar-specific markers. Average similarity between 15 cultivars was 0.650, and varied from 0...

The nucleolus organizing regions (NORs) on the short arms of chromosomes 1A(m) and 5A(m) of diploid wheat, Triticum monococcum L., are at the most distal loci in the linkage maps of these two chromosome arms. This distal location differs from the interstitial location of the Nor loci on chromosome arms 1BS of tetraploid Triticum turgidum L. and hexaploid T. aestivum L., 5DS of T. aestivum and d...

Aim. Development of an algorithm for creating ILP markers suitable breeding studies durum wheat (Triticum durum) and some other types cereals. Methods. Use classical bioinformatics tools to locate potential intron sites target genes in T. use as based on homology contigs rice (Oryza sativa) coding sequences. Analysis exon-intron structure homologous O. sativa, Hordeum vulgare, Aegilops tauschii...

Tibetan semi-wild wheat (Triticum aestivum ssp. tibetanum Shao) is a semi-wild hexaploid wheat resource that is only naturally distributed in the Qinghai-Tibet Plateau. Brittle rachis and hard threshing are two important characters of Tibetan semi-wild wheat. A whole-genome linkage map of T. aestivum ssp. tibetanum was constructed using a recombinant inbred line population (Q1028×ZM9023) with 1...

Fusarium head blight (FHB), caused by species of the fungus Fusarium, is a worldwide disease of wheat (Triticum aestivum L.). The Chinese T. aestivum 'Ning7840' is one of few wheat cultivars with resistance to FHB. To identify differentially expressed genes corresponding to FHB resistance, a cDNA library was constructed using pooled mRNA isolated from glumes of 'Ning7840' harvested at 2, 6, 12,...

Domestication of plants and animals is the major factor underlying human civilization. Cultivated wheats refer mainly to two types: the hexaploid bread wheat (Triticum aestivum) accounting for about 95% of world wheat production, and the tetraploid durum wheat (T. durum) accounting for the other 5%. T. aestivum derived from a cross between domesticated emmer T. dicoccum and the goat grass Aegil...
