Evaluation of tolerance to Pierce's disease and Botrytis in transgenic plants of Vitis vinifera L. expressing the pear PGIP gene.
SUMMARY Polygalacturonase-inhibiting proteins (PGIPs) are plant cell-wall proteins that specifically inhibit fungal endo-polygalacturonases (PGs) that contribute to the aggressive decomposition of susceptible plant tissues. The inhibition of fungal PGs by PGIPs suggests that PGIPs have a role in plant tolerance to fungal infections and this has been observed in transgenic plants expressing PGIP...
متن کاملThe glutaredoxin ATGRXS13 is required to facilitate Botrytis cinerea infection of Arabidopsis thaliana plants.
Botrytis cinerea is a major pre- and post-harvest necrotrophic pathogen with a broad host range that causes substantial crop losses. The plant hormone jasmonic acid (JA) is involved in the basal resistance against this fungus. Despite basal resistance, virulent strains of B. cinerea can cause disease on Arabidopsis thaliana and virulent pathogens can interfere with the metabolism of the host in...
متن کاملBotrytis Bunch Rot: A Disease Requiring Integrated Control
Botrytis bunch rot (BBR), caused by the fungus Botrytis cinerea, causes damage to ripening grape clusters throughout the temperate regions of the world where pre-harvest rains occur. Although pure Botrytis infections free of secondary contaminants can sometimes produce the so-called "noble rot" integral to the production of certain prized dessert wines, a far more common result is a disease tha...
متن کاملMYB46 modulates disease susceptibility to Botrytis cinerea in Arabidopsis.
In this study, we show that the Arabidopsis (Arabidopsis thaliana) transcription factor MYB46, previously described to regulate secondary cell wall biosynthesis in the vascular tissue of the stem, is pivotal for mediating disease susceptibility to the fungal pathogen Botrytis cinerea. We identified MYB46 by its ability to bind to a new cis-element located in the 5' promoter region of the pathog...
متن کاملContrasted responses of Botrytis cinerea isolates developing on tomato plants grown under different nitrogen nutrition regimes
The nutritional status of a plant is known to influence its susceptibility to pathogens. In the case of Botrytis cinerea the role of nitrogen fertilization of various host plants on disease development appears to be variable. This study was carried out to characterize possible variability associated with strains and inoculum density of B. cinerea in its ability to infect leaf-pruning wounds and...
