Karyotype, C-and fluorescence banding pattern, NOR location and FISH study of five Scarabaeidae (Coleoptera) species
TLDR
The study presents detailed karyotipic descripitions of three Rutelinae species (Geniates borelli, Macraspis festiva and Pelidnota pallidipennis), and two Dynastinae Species (Lygirus ebenus and Strategus surinamensis hirtus) with special emphasis on the distribution and variability of constitutive heterochromatin and the nucleolar organizer region (NOR).
The relationships among lemons, limes and citron: a chromosomal comparison
TLDR
The hypothesis that C. medica is a true species while the other nine accessions are hybrids is supported, as all of its chromosome types were clearly represented in limes and lemons, some of them forming heteromorphic pairs.
Karyotype analysis for diploid and polyploid species of the Solanum L.
TLDR
Solanum species were cytogenetically analysed to localize species-specific markers, allowing recognition of particular cytological features in most of the species analysed.
The Genus Uroleucon Mordvilko (Insecta, Aphidoidea) in South America, with a key and descriptions of four new species
Abstract Uroleucon is one of only two genera of Aphidinae to have undergone significant speciation in South America, with a group of about 14 endemic, morphologically similar species feeding on
Chromosomal relationships among cultivars of Citrus reticulata Blanco, its hybrids and related species
TLDR
Those of group I and the Mediterranean mandarins (group II) are the best candidates to represent C. reticulata (sensu Swingle) as a true species.
Karyological features and banding patterns in Arachis species belonging to the Heteranthae section
TLDR
Karyomorphological evaluation of the section Heteranthae of Arachis reveals two clear-cut subgroups within the section from the karyological point of view, suggesting that A. dardani and A. interrupta occupy a basal position in the group due to their moderate asymmetry and satellite type.
Assessment of Genetic Diversity in Contrasting Sugarcane Varieties Using Inter-Simple Sequence Repeat (ISSR) Markers *
TLDR
The present evaluation revealed important contrasting parental candidates regarding their drought response, very promising for future mapping approaches aiming the identification of quantitative trait loci (QTLs) associated to drought in sugarcane.
Karyotype variability in species of the genus Zephyranthes Herb. (Amaryllidaceae–Hippeastreae)
TLDR
Data from this study only partially confirm previous counts for epithets and further enhance the cytological variability data previously reported for the genus, and mechanisms involved in the formation of these karyotypes from chromosomal imbalance data are discussed.
Karyological features and cytotaxonomy of the tribe Vernonieae (Asteraceae)
TLDR
Chromosome numbers are reported for 29 populations of 19 Vernonieae taxa collected mainly in the northeastern region of Brazil, revealing some interesting aspects for understanding of the VernonIEae karyoevolution, especially regarding neotropical members.
Chromosome number variation and evolution in Neotropical Leguminoseae (Mimosoideae) from northeastern Brazil.
TLDR
The data support earlier hypotheses that the Mimosoideae subfamily has a basic number of x = 13 and underwent karyotypic evolution by polyploidy and seems to be a secondary basic number that originated from an ancestral stock with x₁ = 7.
