Elicitor of sorghum phytoalexin synthesis from Colletotrichum graminicola

Physiological and Molecular Plant Pathology, 1990
Abstract Extracts of conidia and the conidial mucilage of Colletotrichum graminicola contained materials that elicited the accumulation of deoxyanthocyanidin phytoalexins in sorghum mesocotyls and juvenile sorghum leaves. Elicitor activity was associated with peptide and carbohydrate components extracted from conidia and with peptides removed from ...

Nature of adhesive material of Colletotrichum graminicola appressoria

Transactions of the British Mycological Society, 1978
The nature of the adhesive ‘mucilage’ of the appressoria of Colletotrichum graminicola (Ces.) Wils. was studied by testing the ability of ammonium oxalate, sodium hydroxide or hemicellulase to release appressoria from glass coverslips on which they had formed. Because only sodium hydroxide or hemicellulase released appressoria, it is concluded that the

Pipecolic Acid‐Induced Physiological and Biochemical Changes in Maize Hamper Colletotrichum graminicola Infection

Plant Pathology
Anthracnose, caused by Colletotrichum graminicola, is an important foliar disease on maize. We hypothesised that pipecolic acid (PA) could boost the defence of maize leaves against fungal infection.

Improvement of catalytic performance of endoglucanase CgEndo from Colletotrichum graminicola by site-directed mutagenesis.

Enzyme and Microbial Technology, 2021
In order to improve the catalytic efficiency of cellulase for more effective utilization of lignocellulose, a novel endoglucanase (CgEndo) from Colletotrichum graminicola was expressed by Pichia pastoris X33 and modified by site-directed mutagenesis. Two

Two homeobox transcription factors CgrHtf1 and CgrAfh1 hierarchically regulate asexual sporulation and appressorium formation in the maize anthracnose fungus Colletotrichum graminicola.

Fungal Biology
Maize anthracnose, caused by the fungal pathogen Colletotrichum graminicola, is among the most devastating diseases affecting maize production. Homeobox transcription factors (HTFs) regulate key developmental and physiological processes in eukaryotes ...

Characterization of two divergent β-tubulin genes from Colletotrichum graminicola

Gene, 1990
We have cloned and sequenced two beta-tubulin genes, TUB1 and TUB2, from the phytopathogenic fungus, Colletotrichum graminicola. The nucleotide sequences of the coding regions of the two genes are only 72.8% homologous. This divergence is reflected in the deduced amino acid (aa) sequences which differ at 94 aa residues. Comparison with the aa sequences

Evaluation of antifungal efficacy of Alternaria alternata on Colletotrichum graminicola

Dutse Journal of Pure and Applied Sciences
Anthracnose caused by Colletotrichum graminicola is one of the diseases impacting on the yield of sorghum in Nigeria. This study was carried out to evaluate the antifungal efficacy of Alternaria alternata on C. graminicola.

A novel thermostable and halotolerant xylanase from Colletotrichum graminicola

Journal of Molecular Catalysis B: Enzymatic, 2016
Abstract A novel endoxylanase from Colletotrichum graminicola (Excg1) was purified. Similar apparent molecular masses were estimated by gel filtration (17.3 ± 1.9 kDa) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (20.0 ± 2.4 kDa), suggesting that Excg1 is monomeric. The enzyme showed good halotolerance, retaining about 85% and 50% of

The CgrMbp1-CgrSwi6 complex regulates vegetative growth, asexual development, and pathogenicity in the maize anthracnose fungus Colletotrichum graminicola.

Microbial Pathogenesis
Colletotrichum graminicola is the main pathogen causing maize anthracnose, leading to substantial agricultural losses. Accurate regulation of the cell cycle is crucial for fungal development and pathogenicity.
