Method to immobilize the aphid-pathogenic fungus Erynia neoaphidis in alginate matrix for biocontrol
Article Abstract:
A method to immobilize the Erynia neoaphidis hyphae in alginate matrix was developed to determine whether conidia ejected from aliginate beads still infect aphid hosts. Results show that a 40% concentration of fungal biomass produced more conidia than in 20% and 10% concentration and persisted even after the beads were dried overnight and stored at four degree centigrade for four days. Moreover, algination seems to be a potential tool for using E. neoaphidis in aphid pests biocontrol.

Polymorphic chromosomes bearing the Tox2 locus in Cochliobolus carbonum behave as homologs during meiosis
Article Abstract:
The chromosomal location of the Tx2 locus in Cochliobolus carbonum was determined by pulse-field gel electrophoresis and genomic Southern blot analysis with chromosome-specific markers. Hydridization of chromosomal deoxyribonucleic acid with the HTS1 gene probe indicated the location of the Tx2 locus in two chromosomes with different sizes. Furthermore, Tox2-containing chromosomes are produced by reciprocal genomic rearrangement and behave as homologous loci during meiosis.

Differential synthesis of peritoxins and precursors by pathogenic strains of the fungus Periconia circinata
Article Abstract:
Strains of Periconia circinata that are not pathogenic appear to be deficient in the synthesis of peritoxins. This was the conclusion of researchers who found intermediates of peritoxin synthesis only in pathogenic, toxin-producing strains but not in non-pathogenic, non-toxin-producing strains.
