Genome downsizing and karyotype constancy in diploid and polyploid congeners: a model of genome size variation
(Oxford University Press, 2014-09)
Evolutionary chromosome change involves significant variation in DNA amount in diploids and genome downsizing in polyploids. Genome size and karyotype parameters of Hippeastrum species with different ploidy level were ...
Karyotype determination of three Tigridia species (Aspargales, Iridaceae)
(Journal Caryologia, 2018)
El cariotipo de Ennealophus fimbriatus (Iridaceae)
(Universidad Privada Antenor Orrego, 2005-12)
Los cromosomas somáticos de Ennealophus fimbriatus Ravenna fueron
examinados por primera vez mediante técnicas clásicas. El número esporofítico hallado fue 2n = 14 y la fórmula cariotípica resultante fue 6 m + 1 sm*. Se ...
Karyotype studies on populations of two Hypochaeris species (H. catharinensis and H. lutea), Asteraceae, from southern Brazil
(Sociedade Brasileira de Genética, 2013-01)
Hypochaeris is an excellent system for studying different modes of chromosome evolution in plants. We carried out a cytogenetic analysis on populations of 2 Hypochaeris species, comprising 10 populations of H. catharinensis ...
Karyotype analysis and DNA content in some species of Chrysolaena (Vernonieae, Asteraceae)
(Taylor & Francis Ltd, 2013-12-17)
Cytogenetic characterization by karyotyping and determination of DNA content by flow cytometry of five species of Chrysolaena (Vernonieae, Asteraceae) was performed. This is the first study of nuclear DNA content realized ...
Cytogenetic studies in herbertia sw. (iridaceae)
(University Florence Botany Institute, 2009-12)
Conventional Feulgen staining, CMA/DAPI banding and FISH with 18-5.8-26S rDNA probe were used to determine chromosome numbers, karyotypes and physical position of GC or AT rich heterochromatin and rDNA sites in three South ...
Tamia (Iridaceae), a synonym of Calydorea: cytological and morphological evidence
(American Society of Plant Taxonomists, 2008-07)
The monotypic genus Tamia was described by Ravenna in 2001 based on specimens of Calydorea pallens from Bolivia and West-Central Argentina (excluding Córdoba and San Luis). At the same time, Ravenna described Calydorea ...
