Stripe rust of barley, caused by Puccinia striiformis f. sp. hordei (PSH), occurred mainly in California, Idaho, Oregon, and Washington and caused localized damage to barley crops. Growing cultivars with high-temperature, adult-plant resistance and the cropping system contributed to the low level of stripe rust. Stripe rust samples were collected from the four states and tested under controlled...

The actin cytoskeleton has been implicated in plant defense against pathogenic fungi, oomycetes, and bacteria. Actin depolymerizing factors (ADFs) are stimulus responsive actin cytoskeleton modulators. However, there is limited evidence linking ADFs with plant defense against pathogens. In this study, we have isolated and functionally characterized a stress-responsive ADF gene (TaADF3) from whe...

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...

Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive diseases of wheat (Triticum aestivum L.) worldwide. Agropyron cristatum (L.) Gaertn. (2n = 28, PPPP), one of the wild relatives of wheat, exhibits resistance to stripe rust. In this study, wheat-A. cristatum 6P disomic addition line 4844-12 also exhibited resistance to stripe rust. To identify the s...

Rust fungi are devastating plant pathogens and cause a large economic impact on wheat production worldwide. To overcome this rapid loss of resistance in varieties, we generated stable transgenic wheat plants expressing short interfering RNAs (siRNAs) targeting potentially vital genes of Puccinia striiformis f. sp. tritici (Pst). Protein kinase A (PKA) has been proved to play important roles in ...

Wheat stripe rust (caused by Puccinia striiformis f. sp. tritici) is a major disease that damages wheat plants and affects yield all over the world. In recent years, became problem in Egypt. New races appeared caused breakdowns resistant genotypes. To improve resistance Egyptian genotypes, new sources of are urgently needed. research, set 95 genotypes collected from 19 countries, including Egyp...

Puccinia striiformis f. sp. tritici (Pst)’nin neden olduğu sarı pas hastalığı, buğday bitkisinin en yıkıcı hastalığı olup, bu hastalık ile mücadelede etkili kontrol yöntemi dayanıklı bitki kullanılmasıdır. Bunun için yaygın olarak yetiştirilen çeşitlerin mevcut popülasyonuna karşı veya virülensliği yüksek olan Pst ırk/ırklarına test edilmesi gerekmektedir. Çalışma kapsamında, Türkiye'de tescill...

Plant cell walls are composed of polysaccharides such as cellulose, hemicelluloses, and pectins, whose location function differ depending on plant type. UDP-Ara mutases (UAMs) have been reported to play important roles in development response various stresses (abiotic biotic). However, little work has UAM wheat. In this study, we dissected the role family member, UAM3, during interaction betwee...
