Structure, organization, and expression of the alpha prolamin multigenic family bring new insights into the evolutionary relationships among grasses
(Crop Science Soc Amer, 2015-03-01)
Prolamins are the major seed storage proteins of grasses. In maize and related species, prolamins are classified into alpha-, beta-, gamma-, and delta-subclasses by their solubility properties. alpha-prolamins are encoded ...
Chromosomal mapping of rDNAs and H3 histone sequences in the grasshopper rhammatocerus brasiliensis (acrididae, gomphocerinae): extensive chromosomal dispersion and co-localization of 5S rDNA/H3 histone clusters in the A complement and B chromosome
(Biomed Central Ltd., 2011-11-10)
Background: Supernumerary B chromosomes occur in addition to standard karyotype and have been described in about 15% of eukaryotes, being the repetitive DNAs the major component of these chromosomes, including in some cases ...

U1 snDNA chromosomal mapping in ten spittlebug species (Cercopidade, Auchenorrhyncha, Hemiptera)
(Canadian Science Publishing, Nrc Research Press, 2018-01-01)
Spittlebugs, which belong to the family Cercopidae (Auchenorrhyncha, Hemiptera), form a large group of xylemfeeding insects that are best known for causing damage to plantations and pasture grasses. The holocentric chromosomes ...
Genomic organization and comparative chromosome mapping of the U1 snRNA gene in cichlid fish, with an emphasis in Oreochromis niloticus
(Springer, 2012-02-01)
To better understand genomic and chromosomal organization and evolutionary patterns of the U1 snRNA gene in cichlid fish, the gene was cytogenetically mapped and comparatively analyzed in 19 species belonging to several ...

Organization of some repetitive DNAs and B chromosomes in the grasshopper Eumastusia koebelei koebelei (Rehn, 1909) (Orthoptera, acrididae, leptysminae)
(2016-01-01)
B chromosomes occur in approximately 15% of eukaryotes and are usually heterochromatic and rich in repetitive DNAs. Here we describe characteristics of a B chromosome in the grasshopper Eumastusia koebelei koebelei (Rehn, ...
Scattered organization of the histone multigene family and transposable elements in Synbranchus
(Sociedade Brasileira de Genética, 2014)
The fish species Synbranchus marmoratus is widely distributed throughout the Neotropical region and exhibits a significant karyotype differentiation. However, data concerning the organization and location of the repetitive ...
