Disease relevance of Colletotrichum

• Resistance to the toxin and pathogen co-segregated with the expression of the p35 gene through the T3 generation, as did resistance to A. alternata, Colletotrichum coccodes, and Pseudomonas syringae pv. tomato [1].
• The efficacy of sucrose combined with CaCl2 during osmotic dehydration (OD) was tested for the control of Botrytis cinerea, Colletotrichum acutatum, and Penicillium expansum growth on lightly processed apple slices [2].

High impact information on Colletotrichum

• Virulence was increased ninefold and was more rapidly effected; furthermore, the requirement for a long duration at high humidity was decreased by introducing NEP1 encoding a phytotoxic protein, to an Abutilon theophrasti-specific, weakly mycoherbicidal strain of Colletotrichum coccodes [3].
• Here we report that ClaPEX6, an ortholog of PEX6, is required for the fungus Colletotrichum lagenarium to infect host plants [4].
• We report the cloning of a mitogen-activated protein kinase kinase (MEK), CgMEK, from Colletotrichum gloeosporioides and its role in the induction of these developmental processes involved in pathogenesis [5].
• Ethylene induced germination and appressorium formation in the Colletotrichum sp. penetrating climacteric fruit but not in other Colletotrichum strains [6].
• Employing a strategy of targeted gene disruption, we generated a mutant strain (gpdhDelta) defective in glycerol-3-phosphate dehydrogenase in a hemibiotrophic plant pathogen, Colletotrichum gloeosporioides f.sp. malvae [7].

Chemical compound and disease context of Colletotrichum

• Isolation and in vitro and in vivo activity against Phytophthora capsici and Colletotrichum orbiculare of phenazine-1-carboxylic acid from Pseudomonas aeruginosa strain GC-B26 [8].

Biological context of Colletotrichum

• The B4 R gene cluster existed prior to the separation of the two major gene pools of cultivated common bean and contains several resistance specificities effective against the fungus Colletotrichum lindemuthianum [9].
• The deduced amino acid sequence was 62% identical to the scytalone dehydratase from Colletotrichum lagenarium [10].
• Biotransformation of progesterone to 14 alpha-hydroxypregna-1,4-diene-3,20-dione, a novel fungal metabolite, by Colletotrichum antirrhini [11].
• Cdc42 is required for proper growth and development in the fungal pathogen Colletotrichum trifolii [12].
• Microbial synthesis of chitinase in solid cultures and its potential as a biocontrol agent against phytopathogenic fungus Colletotrichum gloeosporioides [13].

Anatomical context of Colletotrichum

• L-Phenylalanine ammonia-lyase (EC 4.3.1.5) has been purified over 200-fold from cell cultures of bean (phaseolus vulgaris L.) exposed to elicitor heat-released from the cell walls of the phytopathogenic fungus Colletotrichum lindemuthianum [14].

Associations of Colletotrichum with chemical compounds

• Targeted gene disruption of glycerol-3-phosphate dehydrogenase in Colletotrichum gloeosporioides reveals evidence that glycerol is a significant transferred nutrient from host plant to fungal pathogen [7].
• The monoclonal antibody, UB25, recognises a glycoprotein specifically located at the biotrophic interface formed in the Colletotrichum lindemuthianum-bean interaction [15].
• A comparison of the pectate lyase genes, pel-1 and pel-2, of Colletotrichum gloeosporioides f.sp. malvae and the relationship between their expression in culture and during necrotrophic infection [16].
• In planta production of indole-3-acetic acid by Colletotrichum gloeosporioides f. sp. aeschynomene [17].
• Cloning and structural analysis of the melanin biosynthesis gene SCD1 encoding scytalone dehydratase in Colletotrichum lagenarium [18].

Gene context of Colletotrichum

• The Colletotrichum lagenariu Ste12-like gene CST1 is essential for appressorium penetration [19].
• Molecular characterization of CLPT1, a SEC4-like Rab/GTPase of the phytopathogenic fungus Colletotrichum lindemuthianum which is regulated by the carbon source [20].
• The mitogen-activated protein kinase gene MAF1 is essential for the early differentiation phase of appressorium formation in Colletotrichum lagenarium [21].
• Identification of a gene product induced by hard-surface contact of Colletotrichum gloeosporioides conidia as a ubiquitin-conjugating enzyme by yeast complementation [22].
• The OSC1 gene, encoding a MAP kinase (MAPK) related to yeast Hog1, was isolated from the fungal pathogen Colletotrichum lagenarium that causes cucumber anthracnose [23].

Analytical, diagnostic and therapeutic context of Colletotrichum

• Preliminary bioassays indicated that methylene chloride extracts of seeds of both species contained selective phytotoxic activity against monocots and antifungal activity against Colletotrichum fragariae [24].
