dc.description.abstractElectrophoretic karyotypes of eight wild-type strains of Metarhizium anisopliae var. anisopliae were obtained by pulsed-field gel electrophoresis. These strains were isolated from insects of six different Brazilian states. The chromosomal DNA molecules of three strains were separated into seven bands and of five strains into eight bands. Chromosome length polymorphisms were also observed. The size of the chromosomal DNA of all strains varied between 7.7 and 0.9 Mb using the Aspergillus nidulans chromosomes as size standards. The total genome size of these strains was estimated in at least 29.7 Mb. Some correlations between differences in karyotype and occurrence of parasexual cycle likewise the host specificity were discussed.en
dc.description.abstractCariótipos de oito linhagens selvagens do fungo entomopatogênico Metarhizium anisopliae var. anisopliae foram obtidos em gel, por eletroforese em campo pulsado. As linhagens foram isoladas de insetos provenientes de seis estados brasileiros. As moléculas de DNA cromossômico de três linhagens foram separadas em sete bandas e, de cinco linhagens, em oito bandas. Polimorfismo de tamanho cromossômico também foi observado. O tamanho do DNA cromossômico de todas as linhagens variou de 7,7 a 0,9 Mb, utilizando-se DNA cromossômico de Aspergillus nidulans como padrão. O tamanho do genoma total foi estimado em pelo menos 29,7 Mb. Algumas correlações entre semelhanças e diferenças no cariótipo eletroforético e a ocorrência do ciclo parassexual como também a especificidade com insetos hospedeiros foram discutidas.pt-BR
