The sequence of the wheat mltochondrial gene for cytochrome oxidase subunit I (COI) predicts a hydrophoblc protein of 524 amlno acids that shows strong similarity to those of maize (99% nucleotide identity), soybean (94%) and Oenothera (93%). Nine of the 30 nucleotide differences seen between the wheat and maize COI genes (arrowheads) lead to amlno acid substitutions, many of which occur at the...

BACKGROUND In continuation of our previously interest in the saccharification of agriculture wastes by Bacillus megatherium in solid state fermentation (SSF), we wish to report an investigation and comparative evaluation among Trichoderma sp. for the saccharification of four alkali-pretreated agricultural residues and production of hydrolytic enzymes, carboxymethyl cellulase (CMCase), filter pa...

The orthologue of Arabidopsis ERECTA gene (ER) in wheat, TaER, is considered to be a promising candidate gene for the genetic improvement of water use efficiency (WUE) and drought tolerance in breeding programs. In this study, we isolated two distinct homologues (TaER1 and TaER2) of TaER genes in common wheat through in silico screening and PCR-based homologous cloning. Sequence analysis reveal...

objective: this research was carried out as a greenhouse experiment in the form of a completely randomized factorial design (crd) in three-run sequences. the research aimed at investigating the impacts of nicosulfuron (cruz) and rimsulfuran (titus) residues on the growth of wheat in two soil types which differed in their levels of organic compounds and salinity. methods: treatment of the experi...

introduction: a mixture of wheat flour, water, salt, yeast and other optional ingredients such as preservatives, enzymes, whey powder, surfactants, sugar, fibres and improvers form bread dough. enrichment of dough and bakery products by dietary fibres such as wheat bran and resistant starch, beta-glucans and inulin has been reported (peressini, & sensidoni, 2009; hager, ryan, schwab, gänzle, o’...

A methodology was developed to estimate quantities of crop residues that can be removed while maintaining rain or wind erosion at less than or equal to the tolerable soil-loss level. Six corn and wheat rotations in the 10 largest corn-producing states were analyzed. Residue removal rates for each rotation were evaluated for conventional, mulch/reduced, and no-till field operations. The analyses...

A new wheat dimeric alpha-amylase inhibitor, designated WDAI-3, has been characterized. WDAI-3 is a homodimeric protein active against alpha-amylase from human saliva and from the insect Tenebrio molitor, but inactive against that from pig pancreas or against trypsin. Its N-terminal amino acid sequence is closer to those of the wheat dimeric inhibitors 0.19 and 0.53 (89-91% identical positions ...

In a survey conducted in 1984 in Essex, Lambton, and Middlesex Counties of Ontario, Canada, greater incidences of head blight and greater concentrations of deoxynivalenol in grain were observed in fields of winter wheat planted after corn than in those planted after soybeans, barley, and mixed grains. Neither head blight nor deoxynivalenol level were correlated significantly with soil P, K, or ...

Substitutions in the amino-proximal region of wheat streak mosaic virus (WSMV) HC-Pro were evaluated for effects on transmission by the wheat curl mite (Aceria tosichella Keifer). Alanine substitution at cysteine residues 16, 46 and 49 abolished vector transmission. Although alanine substitution at Cys20 had no effect, substitution with arginine reduced vector transmission efficiency. Random su...
