Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation...

cotton cultivar coker has been already transformed with recombinant pbi121-chi via agrobacterium tumefaciens. the t-dna region of pbi121-chi carries the chitinase (chi ) gene from bean and is under the control of the camv35s promoter. t1 and t2 progenies of transgenic cotton containing the chi gene were used in this study.  polymerase chain reaction (pcr), southern and western blotting data con...

An antifungal metabolite, oosporein, was isolated from the culture of Verticillium psalliotae that produced the antagonistic effects on Phytophthora infestans. Oosporein exhibited a significant growth-inhibitory effect on P. infestans in comparison with other phytopathogenic fungi.

The incidence of respiratory symptoms caused by grain dust during harvesting was surveyed in a group of Lincolnshire farmers. A quarter complained of respiratory distress after working on combine harvesters or near grain driers and elevators, with cough, wheezing, and breathlessness, sometimes so severe as to prevent work. The airborne dust around combine harvesters contained up to 200 million ...

Microorganisms from culture collections and isolates from nature were screened for the ability to catalyze the regioselective glucosylation of pyridoxine (PN) to produce pyridoxine 5'-alpha-D-glucoside (PN-5'-alpha-G) or pyridoxine 4'-alpha-D-glucoside (PN-4'-alpha-G). Transglucosylation activity specific to 5'-position of PN was found in fungi belonging to genera such as Coriolus and Verticill...

Ten strains of fungi were tested for tolerance to the fungicide benomyl. Verticillium chlamydosporium strain 2 did not grow in the presence of benomyl; Drechraeria coniospora strains 1 and 2 and Chaetomium sp. tolerated only 0.1 mug benomyl/ml medium; Acremonium bacillisporum, an unidentified fungus, and Phoma chrysanthemicola uniformly grew at 1 mug/ml, but some hyphae grew at higher benomyl c...

Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...
