The aim of our research is the screening of extracts of marine sponges for their antifungal activity against phytopathogenic fungi. The in vitro screening of hydroalcoholic and organic extracts of ten marine sponges from Atlantic coast of Morocco against five phytopathogenic fungi (Fusarium oxysporum f.sp. melonis, Fusarium oxysporum f.sp. radicis-lycopersici, Fusarium oxysporum f.sp. ciceris, ...

Fusarium oxysporum f. sp. lycopersici, Verticillium spp., and nematodes, as well virus diseases that negatively affect production with limited chemical control cause significant losses in greenhouse tomato cultivation. The practical effective side of controlling is genetic by breeding. Using a genomic approach for plant breeding more sustainable way to disease pests. development the resistant l...

Pathogens and hosts are in an ongoing arms race and genes involved in host-pathogen interactions are likely to undergo diversifying selection. Fusarium plant pathogens have evolved diverse infection strategies, but how they interact with their hosts in the biotrophic infection stage remains puzzling. To address this, we analyzed the genomes of three Fusarium plant pathogens for genes that are u...

ABSTRACT Thirty-nine isolates of Fusarium oxysporum were collected from tomato plants displaying wilt symptoms in a field in California 2 years after F. oxysporum f. sp. lycopersici race 3 was first observed at that location. These and other isolates of F. oxysporum f. sp. lycopersici were characterized by pathogenicity, race, and vegetative compatibility group (VCG). Of the 39 California isola...

Plants and animals rely on immune receptors, known as nucleotide-binding domain and leucine-rich repeat (NLR)-containing proteins, to defend against invading pathogens and activate immune responses. How NLR receptors respond to pathogens is inadequately understood. We previously reported single-residue mutations that expand the response of the potato immune receptor R3a to AVR3a(EM), a stealthy...

Fungal endophytes were isolated from the leaves, stems and roots of two widely used medicinal plantsviz.,Andrographis paniculata (Burm. f.) Wall. exNeesand Centella asiatica (L.)Urban. A total 28 endophytic fungi identified based on morphological molecular analyses. The were: Aspergillus flavus (Link), A. fumigatus (Fresen.), niger (Tiegh), terreus (Thom), Cladosporium sp., Colletotrichum Curvu...

Fusarium head blight caused by oxysporum f. sp. Radicis-lycopersici (FORL) is a constraint to tomato cultivation in Korhogo, Côte dIvoire. To control this disease, the antifungal activity of essential oils extracted from certain plants was evaluated comparison with that synthetic fungicide for use. In vitro tests were performed on different life stages FORL. The vivo evaluations consisted ca...

Medicinal herbs are the potential sources for antimicrobial compounds against soil-borne pathogens. The present investigation focuses on assessing efficacy of antifungal activity volatile organic (VOCs) produced by seven different medicinal in suppression F. oxysporum f.sp. lycopercisi, causal agent wilt disease tomato plants. Among samples tested in-vitro, blend VOCs emitted from mint (Mentha ...
