VqMYB154 promotes polygene expression and enhances resistance to pathogens in Chinese wild grapevine

The Protein Elicitor PevD1 Enhances Resistance to Pathogens and Promotes Growth in Arabidopsis

The protein elicitor PevD1, isolated from Verticillium dahlia, could enhance resistance to TMV in tobacco and Verticillium wilt in cotton. Here, the pevd1 gene was over-expressed in wild type (WT) Arabidopsis, and its biological functions were investigated. Our results showed that the transgenic lines were more resistant to Botrytis cinerea and Pseudomonas syringae pv. tomato DC3000 than the WT...

Ectopic Expression in Arabidopsis thaliana of an NB-ARC Encoding Putative Disease Resistance Gene from Wild Chinese Vitis pseudoreticulata Enhances Resistance to Phytopathogenic Fungi and Bacteria

Plant resistance proteins mediate pathogen recognition and activate innate immune responses to restrict pathogen proliferation. One common feature of these proteins is an NB-ARC domain. In this study, we characterized a gene encoding a protein with an NB-ARC domain from wild Chinese grapevine Vitis pseudoreticulata accession "Baihe-35-1," which was identified in a transcriptome analysis of the ...

Evaluating wild grapevine tolerance to copper toxicity.

We evaluate copper tolerance and accumulation in Vitis vinifera ssp. sylvestris in populations from a copper contaminated site and an uncontaminated site, and in the grapevine rootstock "41B", investigating the effects of copper (0-23 mM) on growth, photosynthetic performance and mineral nutrient content. The highest Cu treatment induced nutrient imbalances and inhibited photosynthetic function...

Identification of disease resistance genes from a Chinese wild grapevine (Vitis davidii) by analysing grape transcriptomes and transgenic Arabidopsis

Heterologous Expression of the Secale cereal Thaumatin-Like Protein in Transgenic Canola Plants Enhances Resistance to Stem Rot Disease

Canola (Brassica napus L.) is an important oilseed crop. A serious problem in cultivation of this crop andyield loss, are due to fungal disease stem rot caused by Sclerotinia sclerotiorum. The pathogenesis-related(PR) proteins have the potential for enhancing resistance against fungal pathogen. Thaumatin-like proteins(TLPs) have been shown to have antifungal activity on variou...
