Reactive oxygen species and plant resistance to fungal pathogens.
Reactive oxygen species (ROS) have been studied for their role in plant development as well as in plant immunity. ROS were consistently observed to accumulate in the plant after the perception of pathogens and microbes and over the years, ROS were postulated to be an integral part of the defence response of the plant. In this article we will focus on recent findings about ROS involved in the in...
متن کاملTranscriptional Plant Responses Critical for Resistance Towards Necrotrophic Pathogens
Plant defenses aimed at necrotrophic pathogens appear to be genetically complex. Despite the apparent lack of a specific recognition of such necrotrophs by products of major R genes, biochemical, molecular, and genetic studies, in particular using the model plant Arabidopsis, have uncovered numerous host components critical for the outcome of such interactions. Although the JA signaling pathway...
متن کاملSaponins versus plant fungal pathogens
The production of low-molecular-weight antimicrobial molecules within plants is one component of defense against pathogens. Among them, preformed antimicrobial compounds (phytoanticipins) are the first biochemical barriers against pathogens. Saponins (a group of phytoanticipins) are present constitutively in plants and play important roles in plant defense. A variety of biological roles have be...
متن کاملFungal plant pathogens in Portugal: Alternaria dauci.
A leaf blight of carrot (Daucus carota) caused by Alternaria dauci was found in Alentejo (Ourique, Portugal). Morphological characteristics of the fungus are described.
متن کاملGenes from mycoparasitic fungi as a source for improving plant resistance to fungal pathogens.
Disease resistance in transgenic plants has been improved, for the first time, by the insertion of a gene from a biocontrol fungus. The gene encoding a strongly antifungal endochitinase from the mycoparasitic fungus Trichoderma harzianum was transferred to tobacco and potato. High expression levels of the fungal gene were obtained in different plant tissues, which had no visible effect on plant...
