De novo assembly and characterization of the root transcriptome of Aegilops variabilis during an interaction with the cereal cyst nematode.

Only registered users can translate articles

BACKGROUND Aegilops variabilis No.1 is highly resistant to cereal cyst nematode (CCN). However, a lack of genomic information has restricted studies on CCN resistance genes in Ae. variabilis and has limited genetic applications in wheat breeding. RESULTS Using RNA-Seq technology, we generated a root

RNA-Seq Based Identification of Candidate Parasitism Genes of Cereal Cyst Nematode (Heterodera avenae) during Incompatible Infection to Aegilops variabilis.

One of the reasons for the progressive yield decline observed in cereals production is the rapid build-up of populations of the cereal cyst nematode (CCN, Heterodera avenae). These nematodes secrete so-call effectors into their host plant to suppress the plant defense responses, alter plant

Cereal cyst nematode resistance conferred by the Cre7 gene from Aegilops triuncialis and its relationship with Cre genes from Australian wheat cultivars.

Only registered users can translate articles

Cereal cyst nematode (CCN; Heterodera avenae Woll.) is a root pathogen of cereal crops that can cause severe yield losses in wheat (Triticum aestivum). Differential host-nematode interactions occur in wheat cultivars carrying different CCN resistance (Cre) genes. The objective of this study was to

Characterization of Resistance to the Cereal Cyst Nematode in the Soft White Winter Wheat 'Madsen'.

Only registered users can translate articles

The cereal cyst nematode (CCN) has a significant negative impact on production of wheat in China. The presence of pathotypes of both Heterodera avenae and H. filipjevi makes it necessary to identify genetic resources with a wide spectrum of resistance. Results of this study confirmed that the soft

The Tryptophan decarboxylase 1 Gene From Aegilops variabilis No.1 Regulate the Resistance Against Cereal Cyst Nematode by Altering the Downstream Secondary Metabolite Contents Rather Than Auxin Synthesis.

Cereal cyst nematode (CCN, Heterodera avenae) is a most important pathogen of wheat and causes tremendous yield loss annually over the world. Since the lack of resistance materials among wheat cultivars, identification and characterization of the resistance-related genes from the relatives of wheat

A directed search for DNA sequences tightly linked to cereal cyst nematode resistance genes in Triticum tauschii.

Only registered users can translate articles

An improved system for identifying DNA sequences linked to a targeted region was developed by fractionating DNA sequences prior to polymerase chain reaction (PCR) analysis. In an attempt to identify DNA markers linked to a strong CCN resistance gene, Ccn-D1, in Triticum tauschii, DNA samples from

Analysis of ascorbate peroxidase genes expressed in resistant and susceptible wheat lines infected by the cereal cyst nematode, Heterodera avenae.

Only registered users can translate articles

Changes in ascorbate peroxidase (APX) enzyme activity in response to nematode (Heterodera avenae) attack were studied in roots of three hexaploid wheat lines carrying Cre2, Cre5, or Cre7 nematode resistance genes and the susceptible Triticum aestivum cv. Anza. A spectrophotometric analysis was

Corrigendum: The Tryptophan decarboxylase 1 Gene From Aegilops variabilis No.1 Regulate the Resistance Against Cereal Cyst Nematode by Altering the Downstream Secondary Metabolite Contents Rather Than Auxin Synthesis.

Partial Resistance to Heterodera avenae in Wheat Lines with the 6M v Chromosome from Aegilops ventricosa.

Only registered users can translate articles

Lines of wheat with the 6M(v) chromosome from Aegilops ventricosa display partial resistance to both pathotypes Hal2 and Ha41 of Heterodera avenae. With either pathotype, the effect of this alien chromosome on cyst production, size, and fecundity was expressed in resistance tests. Partial resistance

Assignment of Aegilops variabilis Eig chromosomes and translocations carrying resistance to nematodes in wheat.

Only registered users can translate articles

The allotetraploid species Aegilops variabilis Eig (2n = 28, UUSvSv) belongs to the tribe Triticeae and is closely related to wheat. One accession, Ae. variabilis No. 1, was found to be resistant to the cereal cyst nematode (CCN) and the root-knot nematode (RKN). As the genetic variability for

Root enzyme activities associated with resistance to Heterodera avenae conferred by gene Cre7 in a wheat/Aegilops triuncialis introgression line.

Only registered users can translate articles

The effect of Cereal cyst nematode (Heterodera avenae) infection on the expression of putative root defence-related enzymes, peroxidase (PER), esterase (EST) and superoxide dismutase (SOD), was studied in roots of a wheat/Aegilops triuncialis introgression line TR-3531 carrying the Cre7 resistance

Resistance gene analogs within an introgressed chromosomal segment derived from Triticum ventricosum that confers resistance to nematode and rust pathogens in wheat.

Only registered users can translate articles

A resistance (R) gene-rich 2S chromosomal segment from Triticum ventricosum contains a cereal cyst nematode (CCN; Heterodera avenae) R gene locus CreX and a closely linked group of genes (Sr38, Yr17, and Lr37) that confer resistance to stem rust (Puccinia graminis f. sp. tritici), stripe rust (P.

Resistance to Heterodera filipjevi and H. avenae in winter wheat is conferred by different QTL.

Only registered users can translate articles

The co-existence of cereal cyst nematode (CCN) species Heterodera avenae and H. filipjevi together with multiple pathotypes is a limiting factor for wheat production in China. Some of the known genes for resistance to CCN are not effective against both nematode species, which complicates breeding
