The chromosome number and heterochromatin distribution pattern suggest differentiation among species of the Stylosanthes scabra-seabrana complex. Author(s): LIRA, I. C. S. A.; MELO, N. F. de; ANTONIO, R. P.; OLIVEIRA, R. S. de; QUEIROZ, M. A. The genus Stylosanthes has economic importance in semi-arid regions and requires studies that reveal complex relationships between species involving of Stylosanthes identified as S. scabra, in order t... ...

Chromosome study in Schistocerca (Orthoptera-Acrididae-Cyrtacanthacridinae): karyotypes and distribution patterns of constitutive heterochromatin and nucleolus organizer regions (NORs). Author(s): SOUZA, M. J. de; MELO, N. F. de Chromosome analyses were performed in two grasshopper species of the genus Schistocerca, S. pallens and S. flavofasciata. Both species shared the same diploid number (2n = 23, X in males; 2n = 24, XX... ... Repository: BDPA Publication year: 2007

Taxonomic implications and karyotype evolution of this group are discussed and cor-related with previous data from the literature. Repository: BDPA Publication year: 2011
Effect of heat shock during in vitro maturation on heterochromatin compaction in bivone embryos at 4- and 8- cell stages: preliminary study. Author(s): CAMARGO, L. S. de A.; AGUIRRE-LAVIN, T.; ADENOT, P.; ARAUJO, T. D.; SOUZA, E. D.; BEAUJEAN, N. Repository: BDPA Publication year: 2015

A comparative cytogenetic analysis between the grasshopper species Chromacris nuptialis and C. speciosa (Romaleidae): constitutive heterochromatin variability and rDNA sites. Author(s): LORETO, V.; STADTLER, E.; MELO, N. F. de; SOUZA, M. J. The chromosomes of Chromacris nuptialis and C. speciosa were comparatively analyzed using different cytogenetic techniques, in order to determine the level of karyotypic similarities and differences b... ...
