Cytogeographie analysis of southern South American species of Stemodia (Scrophulariaceae)
(Finnish Zoological Botanical Publishing Board, 2009-12)
Chromosome numbers for 52 populations representing eight South American species of Stemodia (Scrophulariaceae) were determined. The numbers 2n = 22 found in S. hassleriana and S. palustris, and 2n = 44 in S. lobelioides ...
Stomatal micromorphology in a complex of Mimosa section Mimosa (Fabaceae)
(Springer Wien, 2021-05)
The genus Mimosa Linnaeus (Leguminosae) comprises more than 530 species, being one of the most diversified genera in the family. A vast morphologic variability has been described at all infrageneric levels. Considering ...

New records and range expansion for Paspalum procurrens and P. volcanense in northwestern Argentina and southeastern Bolivia
(Pensoft editor, 2019-12-31)
Paspalum procurrens Quarin and P. volcanense Zuloaga, Morrone & Denham are two rare species of South American grasses inhabiting geographically restricted areas which are exposed to ecological degradation due to landscape ...
Occurrence of 2 n microspore production in diploid interspecific hybrids between the wild parental species of peanut ( Arachis hypogaea L., Leguminosae) and its relevance in the genetic origin of the cultigen
(Crop Science Society of America, 2020-06)
Unreduced (2n) gametes are the driving force that leads to polyploidization of plants in nature and an important tool for ploidy breeding. Peanut (Arachis hypogaea L., Leguminosae) seems most likely to have originated by ...
The enigmatic invasive Spartina densiflora : A history of hybridizations in a polyploidy context
(Wiley Blackwell Publishing, Inc, 2008-12)
The aim of this study was to explore the origin of the invasive Spartina densiflora by analysing samples from the native region (South America) and from a recently colonized area (California). A combination of various ...
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 ...
Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids
(Wiley Blackwell Publishing, Inc, 2019-06)
Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes ...
Characterization and discovery of miRNA and miRNA targets from apomictic and sexual genotypes of Eragrostis curvula
(BioMed Central, 2019-11-12)
Weeping lovegrass (Eragrostis curvula [Shrad.] Nees) is a perennial grass found in semi-arid regions that is well adapted for growth in sandy soils and drought conditions. E. curvula constitutes a polymorphic complex that ...
Discriminant analysis of principal components and pedigree assessment of genetic diversity and population structure in a tetraploid potato panel using SNPs
(Public Library of Science, 2018-03)
The reported narrow genetic base of cultivated potato (Solanum tuberosum) can be expanded by the introgression of many related species with large genetic diversity. The analysis of the genetic structure of a potato population ...
