tanac1 acts as a negative regulator of stripe rust resistance in wheat, enhances susceptibility to pseudomonas syringae, and promotes lateral root development in transgenic arabidopsis thaliana.	plant-specific nac transcription factors (tfs) constitute a large family and play important roles in regulating plant developmental processes and responses to environmental stresses, but only some of them have been investigated for effects on disease reaction in cereal crops. virus-induced gene silencing (vigs) is an effective strategy for rapid functional analysis of genes in plant tissues. in this study, tanac1, encoding a new member of the nac1 subgroup, was cloned from bread wheat and charac ...	2015	25774162
sharing a host plant (wheat [triticum aestivum]) increases the fitness of fusarium graminearum and the severity of fusarium head blight but reduces the fitness of grain aphids (sitobion avenae).	we hypothesized that interactions between fusarium head blight-causing pathogens and herbivores are likely to occur because they share wheat as a host plant. our aim was to investigate the interactions between the grain aphid, sitobion avenae, and fusarium graminearum on wheat ears and the role that host volatile chemicals play in mediating interactions. wheat ears were treated with aphids and f. graminearum inoculum, together or separately, and disease progress was monitored by visual assessmen ...	2015	25769834
genome-wide characterization of developmental stage- and tissue-specific transcription factors in wheat.	wheat (triticum aestivum) is one of the most important cereal crops, providing food for humans and feed for other animals. however, its productivity is challenged by various biotic and abiotic stresses such as fungal diseases, insects, drought, salinity, and cold. transcription factors (tfs) regulate gene expression in different tissues and at various developmental stages in plants and animals, and they can be identified and classified into families according to their structural and specialized ...	0	25766308
precisely mapping a major gene conferring resistance to hessian fly in bread wheat using genotyping-by-sequencing.	one of the reasons hard red winter wheat cultivar 'duster' (pi 644016) is widely grown in the southern great plains is that it confers a consistently high level of resistance to biotype gp of hessian fly (hf). however, little is known about the genetic mechanism underlying hf resistance in duster. this study aimed to unravel complex structures of the hf region on chromosome 1as in wheat by using genotyping-by-sequencing (gbs) markers and single nucleotide polymorphism (snp) markers.	2015	25765046
adventitious roots of wheat seedlings that emerge in oxygen-deficient conditions have increased root diameters with highly developed lysigenous aerenchyma.	exposing roots of plants to hypoxic conditions is known to greatly improve their anoxic stress tolerance. we previously showed that pre-treatment of wheat seedlings with an ethylene precursor, 1-aminocyclopropanecarboxylic acid (acc), enhanced their tolerance of oxygen-deficient conditions. although acc-pretreated seminal roots of wheat seedlings grown under oxygen-deficient conditions avoided root tip death, they elongated very little. in the present study, we assessed the effects of ethylene o ...	2014	25764431
