Chromosome number and genome size in Atriplex mollis from southern Tunisia and Atriplex lanfrancoi from Malta (Amaranthaceae)
TLDR
The morphological similarities, the monophyly of Atriplex including A. lanfrancoi, support the placement of Cremnophyton within the genus Atri Complex, and the chromosome number and genome size of two Mediterranean Amaranthaceae species are investigated.
Genetic and phenotypic patterns of variabilities in Arenaria grandiflora L. species complex (Caryophyllaceae) : new elements for taxonomy and conservation
TLDR
A significant differentiation among populations' patterns of molecular, cytogenetic and phenotypic variation was detected within the A. grandiflora species complex, which would consider as the preliminary signal for necessary revision for the intraspecific taxonomic keys problematic for this species complex.
Recurrent Events of Polyploidy in Ficus carica L. (Moraceae)
TLDR
The results of this study demonstrate that events of polyploidization in fig are quite a widespread phenomenon, which seems connected to the formation of a triploid cytotype, and large-scale chromosome investigations would be very helpful in understanding the role ofpolyploidy in wild and cultivated fig populations.
Cytology of SW Asian Chenopodiaceae: new data from Iran and a review of previous records and correlations with life forms and C4 photosynthesis
TLDR
It was found that C4 plants represent lower polyploidy levels than C3 plants, and presence of different cytotypes in the widespread species is advantageous as they can occupy different niches.
Ecological effects of Atriplex canescens on planted areas in Iran.
TLDR
Investigation of ecological effects of A. canescens on planted areas in Iran rangelands and critique some items such as adaptation of this species, managing aspects, impacts on vegetation and soil characteristics are provided.
The Ploidy Races of Atriplex confertifolia (Chenopodiaceae)
TLDR
Polyploidy, therefore, appears to have developed independently in several areas of the western United States, and parallel variation in monoploid genome size between diploids and accompanying polyploids can be shown in different parts of the species' range.
Leaf δ13C variability with elevation, slope aspect, and precipitation in the southwest United States
TLDR
It is hypothesized that, in summer-wet areas, this may represent the boundary at which drought stress overtakes other factors in determining the sign of δ13Cleaf with elevation, and the opposition of isotopic trends with elevation in arid versus humid regions cautions against standard correction for elevation in comparative studies ofδ 13Cleaf.
Chromosome races of fourwing saltbush (Atriplex canescens), Chenopodiaceae
TLDR
Throughout its distributional range, A. canescens shows considerable between-population variation, some of this variation may be due to phenotypic plasticity, but most of it appears to be genetic.
Gender-related differences of shrubs in stands of Atriplex canescens with different histories of grazing by cattle.
TLDR
Cattle-grazing may have affected female shrubs more negatively at this site, causing gender-based differential mortality, and/or sex-shifting, which could account for the differences in sex ratios, and for the apparent gender-related differences in shrub age that were observed.
