New arrangements on several species subcomplexes of Triatoma genus based on the chromosomal position of ribosomal genes (Hemiptera - Triatominae)
(Elsevier Science, 2016-09)
The hemipteran subfamily Triatominae includes 150 blood-sucking species, vectors of Chagas disease. By far the most specious genus is Triatoma, assembled in groups, complexes and subcomplexes based on morphological ...
A karyotype comparison between two species of bordered plant bugs (hemiptera, heteroptera, largidae) by conventional chromosome staining, c-banding and rDNA-FISH
(Zoological Institute, 2017-04)
A cytogenetic characterization, including heterochromatin content, and the analysis of the location of rDNA genes, was performed in Largus fasciatus Blanchard, 1843 and L. Rufipennis Laporte, 1832. Mitotic and meiotic ...
Highly GC-rich heterochromatin in chili peppers (Capsicum-Solanaceae): A cytogenetic and molecular characterization
(Elsevier, 2018-08)
Capsicum comprises 35 species of chili peppers and five of them are cultivated worldwide as spices or vegetables. Diploid karyotypes based in x = 12 and x = 13 are common in Capsicum and the constitutive heterochromatin ...
Phylogeny of embiopterans (Insecta)
(Wiley Blackwell Publishing, Inc, 2008-12)
A cladistic analysis of embiopterans, based on 157 species (representing 70% of the known genera) and 186 morphological characters, is presented, as well as a molecular analysis for 22 taxa using genes encoding 16S, 18S ...
Genome re-assignment of Arachis trinitensis (sect. Arachis, Leguminosae) and its implications for the genetic origin of cultivated peanut
(Sociedade Brasileira de Genética, 2010-04)
The karyotype structure of Arachis trinitensis was studied by conventional Feulgen staining, CMA/DAPI banding and rDNA loci detection by fluorescence in situ hybridization (FISH) in order to establish its genome status and ...
Molecular cytogenetic studies of the “Xanthocephalum group” (Asteraceae)
(Springer Wien, 2012-10)
Fourteen North American members of the “Xanthocephalum group” were studied by classical and molecular cytogenetics. Location and number of rDNA sites were determined by FISH. For the 5S rDNA, a probe was obtained from ...
Data reassessment in a phylogenetic context gives insight into chromosome evolution in the giant genus Solanum (Solanaceae)
(Cambridge University Press, 2018-05)
Chromosome data are fundamental in evolution. However, there has been no attempt to synthesize and evaluate the significance of such information from a phylogenetic perspective in the giant genus Solanum, which was the aim ...
Real-time PCR quantification of nitrifying bacteria in a municipal wastewater treatment plant
(American Chemical Society, 2003-01)
Real-time PCR assays using TaqMan or Molecular Beacon probes were developed and optimized for the quantification of total bacteria, the nitrite-oxidizing bacteria Nitrospira, and Nitrosomonas oligotropha-like ammonia ...
The Antarctic and South American species of Deschampsia: phylogenetic relationships and cytogenetic differentiation
(Cambridge University Press, 2021-03)
Deschampsia P. Beauv. is a cosmopolitan grass genus, which grows in cold and temperate regions, including about 15 species growing in South America and Antarctica. The species delimitation is difficult due to the high ...
Revision of the taxonomic position of the xylanolytic Bacillus sp. MIR32 reidentified as Bacillus halodurans and plasmid-mediated transformation of B. halodurans
(Springer Tokyo, 2002-06)
Bacillus sp. MIR32 has been isolated using xylan as the only carbon source, and one of its xylanolytic enzymes has been extensively studied. Biochemical analysis first related this strain to Bacillus amyloliquefaciens, but ...
