Forty isolates of Fusarium verticillioides were recovered from corn seeds using Nash & Snyder media. Seed samples had been collected from the major producing area in Khuzestan and Ardabil provinces. Isolates were tested for their pathogenicity on the corn-detached stalks. Results revealed that all isolates were pathogenic to the plant samples tested. Four hundred and twenty nitrate non-utilizin...

in the present study, vegetative compatibility groups (vcg) of 27 isolates of fusarium solani collected from root and  crown of sugar beets of different provinces in iran were determined using nitrate non– utilizing (nit) mutants. totally, 222 nit mutants were generated from 27 isolates using pdc medium. based on the weak growth on basal medium containing one of four nitrogen sources the phenot...

Different formae speciales of Fusarium oxysporum are the main causal agent of Fusarium wilts. In 2008 and 2009 we collected F. oxysporum samples from symptomless Abutilon theophrasti, xanthium strumarium, Chenopodium album, Matricaria perforata, Ambrosia artemisiifolia, Polygonum lapathifolium, Sonchus arvensis, Amaranthus blitoides, Amaranthus retroflexus, Datura stramonium, Sorghum halepense ...

PURPOSE To investigate whether three-dimensional (3D) images cause nearwork-induced transient myopia (NITM) more than 2D images and whether there is any difference between 3D images with crossed and uncrossed disparities in the development of NITM. METHODS Twenty-five volunteers, enrolled in this study, watched 2D and 3D movies and read 3D texts with crossed and uncrossed disparities for 2 to...

Colletotrichum lindemuthianum, the causative agent of bean anthracnose, is one of the most common pathogens leading to expressive damage to plants beyond presenting noticeable variability. The knowledge on vegetative compatibility groups (VCGs) is of particular interest in asexual fungi as they subdivide the population in groups that can exchange genetic information via heterokaryosis and the p...
