Wheat seedlings were grown in presence of CdCl2 (0-200 µM) and Pb(NO3)2 (0-2000 µM) separately. The growth of metal-treated seedlings was significantly depressed. The activities of antioxidative enzymes namely superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (POX) were altered both in root and shoot tissues of 7-d-old seedlings. Under Cd stress, SOD activity in roots was undetectable even at the lowest Cd concentration (50 µM) whereas in shoots it declined sharply with increasing Cd levels. The activity of CAT declined to a greater extent in roots than in shoots. Even though the POX activity increased nine times in shoots, a decreasing trend was observed in root tissues due to Cd stress. Under Pb stress, the induction in SOD activity and...

The direct and relative contribution of characters associated with forage production were evaluated in a comparative assay of wheat cultivars to contribute to an ideotype defnition when selecting double purpose material for forage and grain production. Simple correlations for all of the possible combinations among the measured variables were calculated. The correlation partition method, known as path coeffcient, was applied to determine the causes of this association and to measure the relative importance of each factor. Forage production during the vegetative period was measured for each variety at the dates in which the apex reached the double ridge state (3 - 4 in the Nerson scale). The double ridge state was considered the deadline of the vegetative...

Exploiting a wheat EST database to assess genetic diversity

Genet. Mol. Biol.

Karakas,Ozge; Gurel,Filiz; Uncuoglu,Ahu Altinkut.

Expressed sequence tag (EST) markers have been used to assess variety and genetic diversity in wheat (Triticum aestivum). In this study, 1549 ESTs from wheat infested with yellow rust were used to examine the genetic diversity of six susceptible and resistant wheat cultivars. The aim of using these cultivars was to improve the competitiveness of public wheat breeding programs through the intensive use of modern, particularly marker-assisted, selection technologies. The F2 individuals derived from cultivar crosses were screened for resistance to yellow rust at the seedling stage in greenhouses and adult stage in the field to identify DNA markers genetically linked to resistance. Five hundred and sixty ESTs were assembled into 136 contigs and 989 singletons....

Blast disease, caused by the Magnapor the oryzae/griseaspecies complex, occurs in a wide rangeof wild and cultivated gramineous plant species including rice, wheat and barley. We inoculated a collection of cultivated (Hordeum vulgaressp.vul-gareL.) and wild (ssp.spontaneum) barley accessions with M. oryzae Oryzapathotype (MoO),Triticumpathotype (MoT) and Pennisetumpathotype (MsP) to quantify the host status of barley, and to identify sources of blast resistance. Unlike wheat, the barleygene pool is rich with sources of complete and partialresistance againstMagnaporthe. Cultivated barleyappeared a nonhost to MsP, whereas wild barleyshowed some degree of susceptibility. All 153 testedrice accessions were resistant to the MoT isolate,suggesting that rice is...

The chemical composition of wheat kernels (Triticum aestivum L.) directly affects the quality of flour by modifying its functional and technological properties, determining its use by the industry. Field trials were conducted with wheat genotypes BRS 208 and BRS Pardela to evaluate the impact of different forms of urea (conventional, with urease inhibitor, and polymer-protected) and doses of nitrogen applied in topdressing (0, 40, 80 and 120 kg ha-1) in kernel chemical composition and flour technological quality. The experimental design was randomized block with 3x4 factorial structure, with four replications. The data were submitted to analysis of variance (ANOVA) with regression for nitrogen doses, and comparison of means for genotypes and forms of urea...

In this work, we examined the genetic diversity and evolution of the WAG-2 gene based on new WAG-2 alleles isolated from wheat and its relatives. Only single nucleotide polymorphisms (SNP) and no insertions and deletions (indels) were found in exon sequences of WAG-2 from different species. More SNPs and indels occurred in introns than in exons. For exons, exons+introns and introns, the nucleotide polymorphism Π decreased from diploid and tetraploid genotypes to hexaploid genotypes. This finding indicated that the diversity of WAG-2 in diploids was greater than in hexaploids because of the strong selection pressure on the latter. All dn/ds ratios were < 1.0, indicating that WAG-2 belongs to a conserved gene affected by negative selection. Thirty-nine of...

A pesquisa sobre bactérias diazotróficas na cultura do trigo tem demonstrado a necessidade de associar bactérias eficientes a genótipos promissores, os quais se beneficiariam dessa associação. Em um experimento com parcelas subdivididas, instalado em condições de campo, em Mococa (SP), empregando os tratamentos: três doses de N (0, 60 e 120 kg ha-1) e três genótipos de trigo (IAC-24, ITD-19 e IAC-355), foi avaliada a ocorrência de microrganismos diazotróficos endofíticos em raízes desinfestadas superficialmente, utilizando-se três meios de cultivo distintos, NFb, JNFb e LGI-P. Somente para o genótipo IAC-355, houve um ajuste linear ascendente da quantidade de bactérias diazotróficas com o aumento na quantidade de N adicionada, apesar de o mesmo genótipo...

Partial transposase-coding sequences of Mutator-like elements (MULEs) were isolated from a wild einkorn wheat, Triticum urartu, by degenerate PCR. The isolated sequences were classified into a MuDR or Class I clade and divided into two distinct subclasses (subclass I and subclass II). The average pair-wise identity between members of both subclasses was 58.8% at the nucleotide sequence level. Sequence diversity of subclass I was larger than that of subclass II. DNA gel blot analysis showed that subclass I was present as low copy number elements in the genomes of all Triticum and Aegilops accessions surveyed, while subclass II was present as high copy number elements. These two subclasses seemed uncapable of recognizing each other for transposition. The...
