Interaction between TaNOX7 and TaCDPK13 Contributes to Plant Fertility and Drought Tolerance by Regulating ROS Production.

Reactive oxygen species (ROS) homeostasis is critical for both physiological processes and stress responses of plants. NADPH oxidases (NOXs) are the key producers of ROS in plants. However, their functions in ROS homeostasis and plant growth regulation in wheat () are little investigated.

QTL Mapping and Validation of Adult Plant Resistance to Stripe Rust in Chinese Wheat Landrace Humai 15.

Stripe rust caused by f. sp. () is a devastating foliar disease that affects common wheat and barley throughout the world.

Screening for simple sequence repeat markers in Puccinia striiformis tritici based on genomic sequence.

Puccinia striiformis f. sp. tritici (Pst) is the obligate biotrophic fungus responsible for stripe rust wheat.

Isocitrate lyase is required for urediniospore germination of Puccinia striiformis f. sp. tritici.

The PstICL1 gene, which encodes isocitrate lyase, a key enzyme in the glyoxylate cycle, was cloned and characterized in the biotrophic wheat pathogen Puccinia striiformis f. sp. tritici (Pst).

MicroRNAs involving in cold, wounding and salt stresses in Triticum aestivum L.

MicroRNAs (miRNAs) play critical roles in post-transcriptional regulation and act as important endogenous regulators to various stresses. Cold, wounding and high-salinity are three common environmental stress stimuli influencing crops growth and development. In this study, we identified 31 known miRNAs and 3 novel miRNAs in wheat.

Cloning and molecular characterization of a myosin light chain gene from Puccinia striiformis f. sp. tritici.

The fungus Puccinia striiformis f. sp. tritici (Pst), the causal agent of wheat stripe rust, is an obligate biotrophic basidiomycete.

[Characterization and inheritance of resistance to stripe rust in the wheat line Guinong775].

Exploring different types of resistance genes and deploying diversity resistance genes among different wheat producing regions are important strategy to control stripe rust epidemic in large scale. The resistance spectra of the wheat line Guinong 775 at seedling stage was tested in greenhouse with ten isolates of Puccinia triticina West. f.

A conidiation-related gene is highly expressed at the resting urediospore stage in Puccinia striiformis f. sp. tritici.

The production and germination of asexual spores in a diverse group of fungi play a crucial role in their infection cycles. These processes are regulated by a set of genes, namely, conidiation-related genes, involved in the production, morphological characteristics, and differentiation of conidia. In this study, we identified and characterized the PsCon1 gene, which is the first conidiation-related gene identified in Puccinia striiformis f.

Cloning and characterization of the actin gene from Puccinia striiformis f. sp. tritici.

The fungus Puccinia striiformis f. sp. tritici, the causal agent of wheat stripe rust, is an obligate biotrophic basidiomycete.

Saccharothrix yanglingensis sp. nov., an antagonistic endophytic actinomycete isolated from cucumber plant.

An endophytic actinomycete strain, designated Hhs.015(T), was isolated from roots of cucumber seedlings. The endophytic isolate was identified by means of a polyphasic taxonomic approach.

Analysis of differential transcriptional profiling in wheat infected by Blumeria graminis f. sp. tritici using GeneChip.

Powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is a devastating disease of wheat.

Characterization of a wheat HSP70 gene and its expression in response to stripe rust infection and abiotic stresses.

Members of the family of 70-kD heat shock proteins (HSP70 s) play various stress-protective roles in plants. In this study, a wheat HSP70 gene was isolated from a suppression subtractive hybridization (SSH) cDNA library of wheat leaves infected by Puccinia striiformis f. sp.

Characterization of a novel wheat NAC transcription factor gene involved in defense response against stripe rust pathogen infection and abiotic stresses.

Proteins encoded by the NAC gene family constitute one of the largest plant-specific transcription factors, which have been identified to play many important roles in both abiotic and biotic stress adaptation, as well as in plant development regulation. In the current paper, a full-length cDNA sequence of a novel wheat NAC gene, designated as TaNAC4, was isolated using in silico cloning and the reverse transcription PCR (RT-PCR) methods. TaNAC4 sharing high homology with rice OsNAC4 gene was predicted to encode a protein of 308 amino acid residues, which contained a plant-specific NAC domain in the N-terminus.

[Research progress in molecular ecology of Puccinia striiformis f. sp. tritici].

Stripe rust caused by Puccinia striiformis f. sp. tritici Westend is one of the most important epidemic diseases of wheat in the world.

Cloning of a putative hypersensitive induced reaction gene from wheat infected by stripe rust fungus.

The hypersensitive response (HR) is one of the most efficient forms of plant defense against biotrophic pathogens and results in localized cell death and the formation of necrotic lesions. In this study, a novel putative hypersensitive induced reaction (HIR) gene from wheat leaves infected by incompatible stripe rust pathogen CY23, designated as Ta-hir1, was identified by using rapid amplification of cDNA ends (RACE). Ta-hir1 encodes 284 amino acids, with a predicted molecular mass of 31.

[Systemic resistance induced by biocontrol agents in plants and its biochemical and cytological mechanisms].

Microbial biocontrol agents (BCAs) are generally used for controlling plant diseases via antagonistic mechanisms including competition, antibiosis, parasitism, and cross-protection. Some BCAs can even promote plant growth, and provide induced systemic resistance (ISR), i. e.
