Phytophthora megakarya and Phytophthora palmivora, Closely Related Causal Agents of Cacao Black Pod Rot, Underwent Increases in Genome Sizes and Gene Numbers by Different Mechanisms
Phytophthoramegakarya (Pmeg)andPhytophthorapalmivora (Ppal) are closely relatedspecies causingcacaoblackpod rot.Although Ppal is a cosmopolitan pathogen, cacao is the only known host of economic importance for Pmeg. Pmeg is more virulent on cacao than Ppal. We sequenced and compared the Pmeg and Ppal genomes and identified virulence-related putative gene models (PGeneM) that may be responsible ...
متن کاملBiological Control of Phytophthora palmivora Causing Root Rot of Pomelo Using Chaetomium spp.
Phytophthora diseases have become a major impediment in the citrus production in Thailand. In this study, an isolate of Phytophthora denominated as PHY02 was proven to be causal pathogen of root rot of Pomelo (Citrus maxima) in Thailand. The isolate PHY02 was morphologically characterized and identified as Phytophthora palmivora based on molecular analysis of an internal transcribed spacer rDNA...
متن کاملFirst report of Fusarium chlamydosporum causing crown rot and dumping of on Durum wheat in Algeria
Several species of Fusarium infect durum wheat plants in the eastern part of Algeria. Endophytic fungus from random wheat seeds were sampled from fifty locations in eastern Algeria and shows the existence of Fusarium chlamydosporum regarding the macroscopic and microscopic characteristics. Molecular identification using EF1 and ITS1 primers were confirmed the presence of Fusarium chlamydosporum...
متن کاملPhytophthora megakarya and P. palmivora, Causal Agents of Black Pod Rot, Induce Similar Plant Defense Responses Late during Infection of Susceptible Cacao Pods
Phytophthora megakarya (Pmeg) and Phytophthora palmivora (Ppal) cause black pod rot of Theobroma cacao L. (cacao). Of these two clade 4 species, Pmeg is more virulent and is displacing Ppal in many cacao production areas in Africa. Symptoms and species specific sporangia production were compared when the two species were co-inoculated onto pod pieces in staggered 24 h time intervals. Pmeg spora...
متن کاملNegative Chemotaxis of Zoospores of the Fungus Phytophthora palmivora
347 Phytophthora palmivora zoospores are repelled by many low molecular weight cations. This negative chemotactic response occurs at a different threshold concentration for each cation, that for the most effective ion, H+, being 150 ,!AM. The effectiveness of different cations parallels their ionic conductivities, the most active cations having the highest conductivities. It is suggested that t...
