Seven isozyme systems (Sod, 6-Pgd, Me, Est, Skdh, Fdh and Gdh) representing nine loci were used to study the genetic diversity of nine faba bean populations. Seven loci revealed polymorphic bands and showed the same quaternary structure as that found in several species. They revealed a high number of phenotypes. Indeed, from 3 to 9 phenotypes per locus were(More)
Trichoderma strains were sampled in 4 different bioclimatic zones of Tunisia, a Mediterranean North African country with strong climatic and edaphic variability from north to south, to assess the genetic diversity of endemic species of Trichoderma and their relationship to the bioclimatic zones. In all, 53 strains were isolated and identified at the species(More)
Fusarium culmorum is a major pathogen able to cause foot and root rot and the incitant of Fusarium head blight in wheat in Tunisia. The aims of the present study were to evaluate by PCR the type of mycotoxins produced, to determine the mating type and to analyse the genetic diversity by microsatellite markers of 82 F. culmorum isolates recovered from two(More)
We investigated the occurrence ofTrichoderma in the Oueslatia forest located in the centre-west of Tunisia, which represents a good example for studying a distribution ofTrichoderma between different soil horizons of a forest with Mediterranean bioclimate. One hundred-five isolates obtained were identified at the genus level by analysis of morphological(More)
A collection of 13 Aegilops geniculata Roth (geniculate goat grass) populations belonging to different regions of Tunisia (in North and Central) was evaluated on the basis of morphological descriptors and agronomical characters. Morphological diversity was analysed using a set of nineteen quantitative traits. Variance analysis, correlation coefficients and(More)
