The reproductive potential of Meloidogyne graminicola was compared with that of M. incognita on Trifolium species in greenhouse studies. Twenty-five Trifolium plant introductions, cultivars, or populations representing 23 species were evaluated for nematode reproduction and root galling 45 days after inoculation with 3,000 eggs of M. graminicola or M. incognita. Root galling and egg production ...

ABSTRACT The frequency of sexual reproduction has a profound effect on the population structure and the adaptive potential of a facultatively sexual parasite. Little is known about the relationship of quantitative host resistance to the frequency of sex in pathogens. We sampled over 5,000 fungal fruiting bodies from eight different wheat cultivars over a 3-year period. The cultivars possessed v...

A wild species of jute, Corchorus aestuans (family: Tiliaceae), was found to be infected root-knot nematode, Meloidogyne graminicola. The pathogenicity M. graminicola on C. (local cultivar) under pot conditions showed that could infect, reproduce, and incite profuse root galling in aestuans. initial inoculum 10-second stage juveniles per 1000 cm3 soil displayed the highest reproduction factor (...

A de novo search for repetitive elements in the genome sequence of the wheat pathogen Mycosphaerella graminicola identified a family of repeats containing a DNA cytosine methyltransferase sequence (MgDNMT). All 23 MgDNMT sequences identified carried signatures of repeat induced point mutation (RIP). All copies were subtelomeric in location except for one on chromosome 6. Synteny with M. fijiens...

Echinochloa spp. are the most important weeds in rice fields. In this research Fusarium equiseti and Colletotrichum graminicola were isolated from these weeds and then their pathogenicity effects were compared on these weeds and five rice cultivars in a completely random design with three replications in greenhouse conditions. Fungi were inoculated on weeds and rice cultivars using a spore susp...

Colletotrichum graminicola is a systemic vascular pathogen that causes anthracnose stalk rot and leaf blight of maize. In the course of an effort to explore the potential presence and roles of C. graminicola metabolites in maize, ethyl acetate extracts of solid substrate fermentations of several C. graminicola isolates from Michigan and Illinois were found to be active against Aspergillus flavu...

A simple and applicable technique was developed for the detection of soil infestation with rice rootknot nematode, Meloidogyne graminicola by farmers themselves at their fields. The collected soil samples from root-knot nematode infested fields were diluted by adding sterilized sand in the ratio of 1: 1, 1: 3, 1: 7, 1: 15, 1: 31 and 1: 63 and sown with sprouted rice seeds (cv MUT 7029) for dete...
