Hypocrealean fungi (Ascomycota) are known for their diversity of lifestyles. Their vital influences on agricultural and natural ecosystems have resulted in a number of sequenced genomes, which provide essential data for genomic analysis. Totally, 45 hypocrealean fungal genomes constructed a phylogeny. The phylogeny showed that plant pathogens in Nectriaceae diverged earliest, followed by animal pathogens in Cordycipitaceae, Ophiocordycipitaceae and Clavicipitaceae with mycoparasites in Hypocreaceae. Insect/nematode pathogens and grass endophytes in Clavicipitaceae diverged at last. Gene families associated with host-derived nutrients are significantly contracted in diverged lineages compared with the ancestral species. Introgression was detected in certain lineages of hypocrealean fungi, and the main functions of the genes located in the introgressed regions are involved in host recognition, transcriptional regulation, stress response and cell growth regulation. These results indicate that contraction of gene families and introgression might be main mechanisms to drive lifestyle differentiation and evolution and host shift of hypocrealean fungi.

Phyllosticta species associated with citrus diseases in China

et al. 2011

Phyllosticta species associated with diseases of four commercial Citrus species grown in China are reported. Totally, 496 Phyllosticta strains were isolated from mandarins (Citrus reticulata), pomeloes (C. maxima), oranges (C. sinensis) and lemons (C. limon) in the main citrus producing regions across China, and 74 strains were selected for phylogenetic analysis. Analyses inferred from the sequences of internal transcribed spacer region (ITS1, 5.8S nrDNA and ITS2), partial translation elongation factor 1-alpha (TEF1) and partial actin gene (ACT), showed these representative Phyllosticta isolates clustered in four distinct clades corresponding to three known, and one undescribed species. The newly resolved taxon, Phyllosticta citrichinaensis was isolated from leaves and fruits of all four Citrus species and is introduced in this paper. This taxon caused minor damage, showing irregular spots or freckles. Phyllosticta citriasiana, associated with tan spot of pomeloes, was isolated only from pomeloes, and never from lemons, mandarins and oranges. Phyllosticta citricarpa, the citrus black spot pathogen, which is presently subjected to phytosanitary legislation in the EU and United States, was isolated from lemons, mandarins and oranges, but never from pomeloes. The isolates of P. citricarpa clustered in two subclades, one from mandarins, the other from oranges and lemons. P. capitalensis was isolated from all four Citrus species as an endophyte, causing false melanose, or together with P. citricarpa or P. citriasiana. Morphological, cultural and biochemical characters were consistent with the results of phylogenetic analysis. In addition, a specific primer pair Pca8/ITS4 was designed and selected, and its corresponding PCR procedure was developed for the detection of P. citriasiana in this study.

“…In Australia over 20 F. oxysporum formae speciales have been reported (Anon 1955;Simmonds 1956;Johnson 1961;Trimboli 1972;Cook & Dube 1978;Sampson & Walker 1982;Wright et al 1997;Summerell et al 2006a,b;Summerell et al 2010). The recognition that many plant pathogenic Fusarium species are widely distributed in the natural ecosystem has given impetus to studying the extent of FOSC diversity in Australian non-cultivated ecosystems of minimal disturbance (Windels & Kommedahl 1971;Davis 1996;Bentley et al 2007).…”
