Races of Colletotrichum graminicola pathogenic to maize in Brazil

Crop Protection, 2014
Abstract Anthracnose caused by the fungus Colletotrichum graminicola (Ces.) Wilson is the most important disease of maize in Brazil, especially in no-tillage without crop rotation. In this system, maize debris from earlier plantings increases the fungal inoculum potential over time.

Variabilité phénétique duColletotrichum graminicoladu sorgho

Canadian Journal of Plant Pathology, 2001
A comparative intraspecific study of Colletotrichum graminicola (Ces.) G.W. Wilson from sorghum (Sorghum bicolor (L.) Moench) was carried out. Thirty one isolates were used, including 29 from various sites in Burkina Faso and 2 from the American Type Culture Collection (one from sorghum of Porto Rico and the second from maize of Alabama).

The galactose metabolism genes UGE1 and UGM1 are novel virulence factors of the maize anthracnose fungus Colletotrichum graminicola

Molecular Microbiology
Fungal cell walls represent the frontline contact with the host and play a prime role in pathogenesis. While the roles of the cell wall polymers like chitin and branched β‐glucan are well understood in vegetative and pathogenic development, that of the ...

The serine-threonine protein kinase Snf1 orchestrates the expression of plant cell wall-degrading enzymes and is required for full virulence of the maize pathogen Colletotrichum graminicola.

Fungal Genetics and Biology
Colletotrichum graminicola, the causal agent of maize leaf anthracnose and stalk rot, differentiates a pressurized infection cell called an appressorium in order to invade the epidermal cell, and subsequently forms biotrophic and necrotrophic hyphae to ...

Comparison of the physiology of three isolates of colletotrichum graminicola

Mycopathologia et Mycologia Applicata, 1962
Three isolates ofColletotrichum graminicola (Ces.)Wils. (from wheat, orchard grass and alfalfa) were used in an investigation of their comparative physiology. The carbon compounds, lactose, sucrose, d-mannitol, d(+) mannose, d(+) raffinose, dextrose and d(-) levulose and the nitrogen compounds, DL-histidine, L(+) asparagine, L-arginine, DL-tryptophane,

Nitrate-nonutilizing mutants used to study heterokaryosis and vegetative compatibility in Glomerella graminicola (Colletotrichum graminicola)

Experimental Mycology, 1994
Nitrate-nonutilizing (nit) mutants of Glomerella graminicola were recovered by selecting chlorate-resistant sectors. Heterokaryons were formed by complementation between two different classes of nit mutants. Complementation groups were distinguished in nitrogen feeding tests and segregated as two, unlinked genes among random progeny of sexual ...

Quantification of substratum contact required for initiation of Colletotrichum graminicola appressoria

Fungal Genetics and Biology, 2004
Colletotrichum graminicola, like many plant pathogenic fungi develop appressoria on germling apices, to facilitate penetration of their host. Induction of these structures occurs after contact with the host surface has been established by the germling. Surface contact and subsequent development of appressoria by germlings of C. graminicola was assessed

F-actin localization dynamics during appressorium formation inColletotrichum graminicola

Mycologia, 2016
Appressoria are essential penetration structures for many phytopathogenic fungi. Here F-actin localization dynamics were documented during appressorium formation in vitro and in planta in Colletotrichum graminicola Four discernible stages of dynamic F-actin distribution occurring in a programmed order were documented from differentiation of appressoria

The GATA Transcription Factor NsdD Regulates Vegetative Growth, Asexual Sporulation, and Melanin Biosynthesis in Colletotrichum siamense and C. graminicola.

Phytopathology
The genus Colletotrichum infects over 3,000 monocot and dicot plant species, inflicting substantial economic losses globally. GATA zinc finger proteins play a pivotal role as transcription factors governing fungal growth and development.
