در این مطالعه 1200 جدایه قارچ با مشخصات جنس fusarium از گیاهان و اندام های مختلف گیاهی خانواده گندمیان جداسازی، خالص سازی و مورد مطالعه مورفولوژیکی و مولکولی قرار گرفت. بررسی مورفولوژیکی جدایه ها روی محیط های کشت pda، sna، cla و wa+kcl تحت شرایط کنترل شده (دمای 25-22 درجه سانتی گراد و زیر نور nuv در شرایط نوری/تاریکی 12/12 ساعته) انجام گرفت. 35 گونه از این جنس شامل، گونه های fusarium acuminatum...
BACKGROUND AND PURPOSE Fusarium species are avid producers of secondary toxic and carcinogenic metabolites such as fumonisin. Contamination of food and feed products with fumonisin can be hazardous to the health of humans and animals and may lead to agricultural loss. Accordingly, in this study, we aimed to evaluate the effects of Candida parapsilosis on the growth and fumonisin production of F...
Fusarium species section Liseola namely F. fujikuroi, F. proliferatum, F. andiyazi, F. verticillioides, and F. sacchari are well-known plant pathogens on rice, sugarcane and maize. In the present study, restriction analysis of the intergenic spacer regions (IGS) was used to characterize the five Fusarium species isolated from rice, sugarcane and maize collected from various locations in Pen...
The intergenic spacer (IGS) region of the ribosomal DNA was cloned and sequenced in eight species within the Gibberella fujikuroi species complex with anamorphs in the genus Fusarium, a group that includes the most relevant toxigenic species. DNA sequence analyses revealed two categories of repeated elements: long repeats and short repeats of 125 and 8 bp, respectively. Long repeats were presen...
Pre-harvest contamination of forage maize by mycotoxin producing Fusarium species was investigated in the UK in 2011 and 2012. A total of 15 Fusarium species were identified from a collection of 1,761 Fusarium isolates recovered from maize stalks and kernels. This study characterized the diversity of Fusarium species present in forage maize in the UK. The predominant species detected were F. gr...
The incidence of garlic rot has constantly increased in France since the early 2000s. To set up an efficient method protection against this disease, we have clarified its aetiology. This was achieved by surveying from two main French basins production over 3 years. Fungi were isolated 5,493 cloves belonging to pink, purple, and white types. Sequencing translation elongation factor 1α gene 1,171...
Fusarium proliferatum as well F. oxysporum are pathogens with a broad host range that includes garlic (Allium sativum). The losses of due to these increased over the last years. Especially was identified several times main cause postharvest dry rot. This species is also known produce mycotoxins, especially fumonisins. In this study, we aimed identify and study phylogeny diversity in planting st...
