N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) are involved in plant resistance; however, the role of SYP71 in the regulation of plant-pathogen interactions is not well known. In this study, we characterized a plant-specific SNARE in wheat, TaSYP71, which contains a Qc-SNARE domain. Three homologs are localized on chromosome 1AL, 1BL, and 1DL. Using Agrobacterium-mediat...

Differentiation of haustoria on primary infection hyphae of the fungal pathogen Puccinia striiformis was studied in wheat seedlings with two-photon microscopy in combination with a classical staining technique. Our results showed a significant increase in the average haustorium size 22, 44, 68, 92 and 116 h after inoculation (hai). After 116 hai no significant change was observed until 336 hai....

La roya amarilla, causada por el hongo Puccinia striiformis W., sigue siendo una enfermedad importante del trigo en la región de El Bajío, Noroeste México y los Valles Altos centro México. Durante ciclo 2014 se observó epidemia amarilla México, donde tomaron muestras analizaron líneas diferenciales invernadero. Los resultados indicaron que las combinaciones virulencia Yr1, Yr2, Yr3, Yr6, Yr7, Y...

Calreticulin proteins play essential roles in regulating various metabolic processes and in molecular signal transduction in animals and plants. Using homologous PCR, we screened a cDNA library of the wheat resistance gene Yr5 from a near-isogenic line in the susceptible common wheat variety Taichung 29, which was inoculated with an incompatible race CYR32 of Puccinia striiformis. We isola...

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...

Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a destructive disease of wheat worldwide. The disease is preferably controlled by growing resistant cultivars. Wheat cultivar Xiaoyan 6 (XY 6) has been resistant to stripe rust since its release. In the previous studies, XY 6 was found to have higher-temperature seedling-plant (HTSP) resistance. However, the molecular mechanis...
