Metabolic transformation of the brassinosteroid 24-epi-castasterone by the cockroach Periplaneta americana.

چکیده
After feeding of 24-epi-castasterone to the cockroach Periplaneta americana an organ-specific epimerization of the brassinosteroid to 2,24-diepi-castasterone could be detected in female insects. The metabolite being observed only in the ovaries and not in the testes of the insect was identified by GC/MS in comparison with a synthesized authentic sample. Contrary, 24-epi-brassinolide is not metabolized in the sexual organs of Periplaneta americana. This is the first evidence of a metabolic transformation of a brassinosteroid in insects.

متن کاملEvaluation of bacterial infection of external surface and digestive system of cockroach species
Introduction: The presence of cockroaches has health implications, such as nosocomial infection, as the insects move freely from areas within and around hospitals that may harbor pathogenic organisms. The aims of the present study were to detect cockroach species and bacterial infection transmitted by their surface and their digestive system. Methods: In this study we caught 250 cockroac...

متن کاملInterbreeding among deeply divergent mitochondrial lineages in the American cockroach (Periplaneta americana)
DNA barcoding promises to be a useful tool to identify pest species assuming adequate representation of genetic variants in a reference library. Here we examined mitochondrial DNA barcodes in a global urban pest, the American cockroach (Periplaneta americana). Our sampling effort generated 284 cockroach specimens, most from New York City, plus 15 additional U.S. states and six other countries, ...
