Tests were conducted to determine the effects of Profenfos [(0-(4-bromo-2-chlorophenyl) 0-ethyl S-n-propyl-phosphorothioat] on fungal populations and some activities in soil. Profenfos (at 5.4… Expand
Effect of nanoparticles on biological contamination of in vitro cultures and organogenic regeneration of banana.
This study aimed to identify biological contaminants of banana in vitro cultures. We also tested the effect of Zn or ZnO nanoparticles on elimination of some bacterial and fungal contaminants and… Expand
Effects of an organophosphorus insecticide on the growth and cellulolytic activity of fungi
Abstract The organophosphorus insecticide Selecron [O-(4-bromo-2-chlorophenyl) O-ethyl S-n-propyl-phosphorotioate] at 10 and 50 ppm significantly decreased respiration, mycelial protein,… Expand
Effect of the herbicide fluazifop-butyl on fungal populations and activity in soil
The side effects of fluazifop-butyl on soil fungal populations and oxygen uptake were studied by incubating soil samples with a range of fluazifop-butyl concentrations (0, 0.6, 3 and 6 μg g−1) over 8… Expand
Influence of the insecticide Dimethoate on some metabolic activities of five zoosporic fungi
Using sesame water culture and various doses of Dimethoate, no mycelial growth appeared in cultures at rate above 5 ppm. There was no appreciable effect of the low dose of the insecticide (2.5 ppm)… Expand
Physiological aspects of fungi isolated from root nodules of faba bean (Vicia faba L.).
The present study was made to isolate and assess some physiological characteristics of root nodule-colonizing fungi. During this study, 17 fungal species were isolated from root nodule samples taken… Expand
Identification and differential expression of two dehydrin cDNAs during maturation of Jatropha curcas seeds
Plant dehydrin proteins (DHNs) are known to be important for environmental stress tolerance and are involved in various developmental processes. Two full-length cDNAs JcDHN-1 and JcDHN-2 encoding two… Expand
Growth, cell wall-degrading enzymes and aflatoxin production by lemon-rotting fungi in relation to insecticide application
Abstract The effect of the insecticide Sumi Oil on growth, enzymatic activity and aflatoxin production of some lemon-rotting fungi was tested. Lower doses of the insecticide up to 100 ppm increased… Expand
Physiological and molecular mechanisms of salinity tolerance in grafted cucumber
Abstract Salinity is considered as one of the main stress factors, which impact the horticultural crops. Thus, the objective of this research was to study the molecular, biochemical, and… Expand
