Survival of the sclerotial parasite Coniothyrium minitans in soil, when applied as spore suspension or colonised solid substrate (maizemeal-perlite) inocula, and ability to infect Sclerotinia sclerotiorum sclerotia incorporated into the soil after different times was assessed over 6 months. Unambiguous detection of the C. minitans isolate from the indigenous C. minitans soil population was achi...

A preliminary genetic analysis of a number of genetic variants of Volvox carteri f. nagariensis is presented. Techniques are outlined for mutagenesis of Volvox, isolation of mutants and routine genetic analysis. All of the mutants show simple Mendelian segregation patterns and have been tentatively placed in 14 linkage groups.

Coniothyrium zuluense causes a serious canker disease of Eucalyptus in various parts of the world. Very little is known regarding the taxonomy of this asexual fungus, which was provided with a name based solely on morphological characteristics. In this study we consider the phylogenetic position of C. zuluense using DNA-based techniques. Distance analysis using 18S and ITS regions revealed exte...

The marine endophytic fungus Coniothyrium cereale produces the structurally unusual polyketide-type alkaloids (-)-cereolactam (1) and (-)-cereoaldomine (3), incorporating a lactam and an imine functionality, respectively, as well as the related metabolite (-)-trypethelone (2). Compounds 1 and 3 showed selective inhibition of human leukocyte elastase with IC50 values of 9.28 and 3.01 μM, respect...

New 5-[1-(anthracen-9(10H)-ylideneamino)-2-(1H-imidazol-5-yl)ethyl]-1,3,4-thiadiazol-2-amine 3 has been synthesized from condensation reaction of N-anthracen-9(10H)-ylidenehistidine 2 with thiosemicarbazide in phosphorusoxy chloride. The prepared compounds were characterized by FTIR spectroscopy, electronic spectroscopy, NMR and NMR. Preliminary in vitro tests for fungicidal activity show that ...
