Citogenética de acessos de Cratylia sp. (FABACEAE - PAPILIONOIDEAE)
As analises estatisticas relacionadas ao CTLH e CR para os 11 pares cromossomicos mostraram that nao houveram diferencas significativas entre os acessos de C. argentea e tampouco entre esses e o acesso of C. mollis, sendo estes numeros relatados pela primeira vez na literatura.
Karyomorphology of Caesalpinia Species (Caesalpinioideae: Fabaceae) from Caatinga and Mata Atlantica Biomes of Brazil
The karyotype and the chromosome morphometry in five Caesalpinia s.l. spp.
Intra- and interspecific karyotypic variations of the genus Senna Mill. (Fabaceae, Caesalpinioideae)
It is indicated that 2n = 28 is the most common ploidy among species of Senna, although other numbers were observed, apparently due to polyploidy or disploidy events; polysomy and aneusomy were also observed.
Multiple polyploidy events in the early radiation of nodulating and nonnodulating legumes.
- BiologyMolecular biology and evolution
The timing of duplications in the gene trees indicates that the papilionoid WGD occurred in the common ancestor of all papilionoids, and there is evidence for several independent WGDs near the base of other major legume lineages, including the Mimosoideae-Cassiinae-Caesalpinieae (MCC), Detarieae, and Cercideae clades.
The Origin and Phylogenetic Relationships of the Californian Chaparral ‘Paleoendemic’ Pickeringia (Leguminosae)
The hypothesis that Pickeringia is geographically isolated in the flora of western North America is substantiated, an old and phylogenetically distinct lineage of an early diverging group of papilionoid legumes that were much more widely distributed throughout temperate North America and Asia during the Tertiary but whose modern relatives are restricted to southern North America, Central America, and eastern Asia.
Chromosome studies in southern species of Mimosa (Fabaceae, Mimosoideae) and their taxonomic and evolutionary inferences
- BiologyPlant Systematics and Evolution
In this work, chromosome numbers and karyotype parameters of 36 taxa of the genus Mimosa were studied, especially from the southern South America center of diversification. Results support that x =…
An overview on cytogenetics of the genus Onobrychis (Fabaceae) with special reference to O. sect. Hymenobrychis from Iran
The present study reports the chromosome number and meiotic behavior of 25 populations belonging to 10 species of Onobrychis sect. Hymenobrychis from Iran. Most populations showed the chromosome…
A karyological study of Genista sect. Spartocarpus Spach (Cytiseae-Fabaceae)
- Environmental Science
Summary Genista sect. Spartocarpus includes about 20 taxa distributed in the Mediterranean region, with one species (G. radiata) extending into the Alps. Two main diversity centers can be identified:…
Los cariotipos de Cologania grandiflora y Erythrina americana (Leguminosae- Papilionoideae-Phaseoleae) de la Reserva Ecológica del Pedregal de San Ángel, México
- Geography, Biology
Cologania y Erythrina se reconocen como poliploides estabilizados y el hallazgo de un unico par de cromosomas con satelites (dominancia nucleolar) en las especies estudiadas aqui, favorece la opinion of un origen alopoliploide for estos taxa.
Cytogenetics of Mimosa bimucronata (DC.) O. Kuntze (Mimosoideae, Leguminosae): chromosome number, polysomaty and meiosis
Polysomatic cells were detected in the seedlings root-tip cells in 39 out of the 41 populations examined, but were absent in the root-tips of grown plants, and Polysomaty was as well absent in pollen-mother cells.
