| Resumen en inglés | Comparative cytogenetics in threeMeliponaspecies (Hymenoptera: Apidae)with two divergent heterochromatic patternsMarina Souza da Cunha1, Natália Martins Travenzoli1, Riudo de Paiva Ferreira1,2, Edson KuatelelaCassinela1,3, Henrique Barbosa da Silva1, Francisco Plácido Magalhães Oliveira4, Tânia Maria FernandesSalomão1and Denilce Meneses Lopes11Laboratório de Biologia Molecular de Insetos, Departamento de Biologia Geral, Universidade Federal deViçosa, Viçosa, MG, Brazil.2Faculdade de Ciências Gerenciais de Manhuaçu, Campus Alfa Sul, Manhuaçu, MG, Brazil.3Camargo Cancer Center, Centro Internacional de Ensino e Pesquisa (CIPE), São Paulo, SP, Brazil.4Instituto de Medicina Veterinária, Universidade Federal do Pará, Campus de Castanhal, Castanhal, PA,Brazil.AbstractThe genusMeliponais subdivided into four subgenera based on morphological characteristics, and two groupsbased on cytogenetic patterns. The cytogenetic information on this genus is still scarce, therefore, the goal of thisstudy was to characterizeMelipona paraensis, Melipona puncticollis,andMelipona seminigra pernigrausing the fol-lowing techniques: C-banding, DAPI/CMA3fluorochromes, and FISH with an 18S rDNA probe.Melipona paraensis(2n=18) andM. seminigra pernigra(2n=22) were classified as high heterochromatin content species (Group II). Theireuchromatin is restricted to the ends of the chromosomes and is CMA3+; the 18S rDNA probe marked chromosomepair number 4.Melipona puncticollis(2n=18) is a low heterochromatin content species (Group I) with chromosomepair number 1 marked with CMA3and 18S rDNA. Low heterochromatin content is a putative ancestral karyotype inthis genus and high content is not a monophyletic trait (Melikerriapresents species with both patterns). Differencesconcerning the karyotypic characteristics can be observed amongMeliponaspecies, revealing cytogenetic rear-rangements that occurred during the evolution of this genus. Studies in other species will allow us to better |
