Chemical taxonomy of Torrubiella s. lat.: zeorin as a marker of Conoideocrella
چکیده انگلیسی

The insect pathogens in the genus Torrubiella s. lat. were recently divided into new genera based on molecular phylogenetic characters. Isolates collected at various locations in Thailand, were tested for their productivity of a hopane-type triterpene, zeorin (6α,22-dihydroxyhopane), when cultured in potato dextrose broth under static conditions. Among the 49 strains of Torrubiella s. lat. species, Conoideocrella luteorostrata (ten strains) and C. tenuis (seven strains), all collected on scale insects (Hemiptera), produced zeorin, whereas another six strains of Orbiocrella petchii (which was recently removed from Torrubiella) failed in the detection of this secondary metabolite. All other Torrubiella s. lat. (26 strains), collected on other insect hosts including leafhoppers (eight strains), Lepidoptera (one strain), and spiders (17 strains), produced no detectable zeorin. Paecilomyces cinnamomeus (nine strains), the anamorph of C. luteorostrata, also produced zeorin. These results correspond with the recent taxonomic reclassification based on multigene phylogeny.
