The Gibberella fujikuroi species complex with Fusarium anamorphs is the causal of diverse diseases of many important plants. Many of the known species in this species complex produce a wide range of secondary metabolites. In this study, morphological characteristics of 46 isolates from rice, maize, sugarcane and onion and phylogenetic relationships of 22 isolates on the basis of ITS1-5.8S-ITS2 ...

to study the population structure of gibberella fujikuroi species complex, the causal agent of rice foot rot, samples were taken from different rice growing regions of guilan province in 2004. among fourty-one isolates recovered from different cultivars; three isolates did not produce microconidial chain. in order to study the sexual fertility and determine the mating type as well as mating pop...

Global-scale data on the Oligocene to Recent planktic foraminifers and coccoliths from the tropical Pacific and Atlantic Oceans are employed for quantitative testing of alternative models (Red Queen and Stationary Hypotheses) of the relationship between speciation rates, extinction rates, taxonomic diversity, abiotic events, and history of the paleosystem. The results demonstrate that although ...

BACKGROUND AND PURPOSE Pseudomonas aeruginosa is the third most common pathogen causing nosocomial infections. The objective of this study was to investigate the antimicrobial resistance profiles and genetic diversity of hospital isolates of P. aeruginosa and to investigate the presence of several resistance genes and integrons. METHODS In this retrospective study, 48 clinical isolates of P. ...

Assessment of eighty Fusarium proliferatum isolates obtained from maize, rice, sugarcane and onion using AFLP molecular marker separated the isolates into four distinct clusters according to their host’s. Isolates recovered from rice clustered in a distinct group. Isolates from sugarcane grouped in two distinct groups and isolates recovered from maize and onion clustered in a unit group. As wel...

Fusarium wilt caused by Fusarium oxysporum Schltdl. f.sp. phaseoli (Fop), is one of the important diseases of the common bean in Iran and many of the bean growing countries. Incidence of the disease has been reported in tropical and semi-tropical regions of the world. This study was carried out to characterize genetic diversity of F. oxysporum isolates from the common bean by vegetative compati...

Endofitne gljive žive unutar biljaka ne uzrokujući očite simptome bolesti. Korovi koji rastu u blizini poljoprivrednih polja mogu poslužiti kao alternativni domaćin ovih gljiva. Izolirali smo endofitne iz 6 vrsta korova, uobičajenih za istočnu Hrvatsku te bez očitih simptoma bolesti: Abutilon theophrasti, Amaranthus retroflexus, Ambrosia arthemisiifolia, Chenopodium album, Sorghum halepense i X...

Grouping of beta-hemolytic streptococcal isolates by staphylococcal coagglutination was performed with the Phadebact Streptococcus Test to determine whether such isolates could be accurately grouped serologically with 4 h after examination of the primary isolation plates. Of 132 clinical isolates, 131 were correctly grouped by the Phadebact method using the Lancefield precipitation method as th...
