To improve sorghum for bioenergy and forage uses, brown midrib (bmr)6 and -12 near-isogenic genotypes were developed in different sorghum backgrounds. The bmr6 and bmr12 grain had significantly reduced colonization by members of the Gibberella fujikuroi species complex compared with the wild type, as detected on two semiselective media. Fusarium spp. were identified using sequence analysis of a...

Seed as a highly-valuable resource is preserved in collections for many years. Although the seed kept under optimal conditions, monitoring of germination and presence fungi during preservation great importance. Therefore aim this paper to examine health status 43 onion accessions timespan 15 years Institute Field Vegetable Crops collection. Germi?nation samples varied from 7-93%. The collection...

Abstract Fusarium is one of the most important genera phytopathogenic fungi, causing potato wilt in field and tuber dry rot during storage. The objectives this study were to identify species associated with both diseases different growing regions Algeria, assess their pathogenicity. Among 152 isolates collected from symptomatic plants tubers provinces 13 Neocosmospora identified. these three is...

Flowery cushion gall of cacao is a disease complex with six types. Fusarium decemcellulare have been isolated from both flowery and green point galls and recognized as the etiological agent of the disease. In the present work we: i) identified by ITS-rDNA sequencing and/or taxonomy the cultivable fungal species or Operative Taxonomic Units (OTUs) associated with the five symptoms of cushion gal...

The ability of Fusarium species isolated from bananas to produce mycotoxins was studied with 66 isolates of the following species: F. semitectum var. majus (8 isolates), F. camptoceras (3 isolates), a Fusarium sp. (3 isolates), F. moniliforme (16 isolates), F. proliferatum (9 isolates), F. subglutinans (3 isolates), F. solani (3 isolates), F. oxysporum (5 isolates), F. graminearum (7 isolates),...

PURPOSE Fungal ocular infections cause significant ocular morbidity, particularly when diagnosis and treatment are delayed. Accurate morphologic identification of Fusarium spp. beyond the genus is time-consuming and insensitive. It was the purpose of this study to examine the usefulness of the nuclear ribosomal RNA (rRNA) internal transcribed spacer regions (ITS1 and -2) to detect and different...
