Niche evolution in plant polyploids remains controversial and evidence for alternative patterns has been reported. Using the autopolyploid Dianthus broteri complex (2×, 4×, 6× 12×) as a model, we aimed to integrate three scenarios - competitive exclusion, recurrent origins of cytotypes niche filling into single framework polyploid evolution. We hypothesized that high would tend evolve towards extreme niches when low ploidy have nearly filled space. used several ecoinformatics phylogenetic...
Soil salinization is an environmental problem that adversely affects plant growth and crop productivity worldwide. As alternative to the conventional approach of breeding salt-tolerant cultivars, we explored use plant-growth-promoting rhizobacteria (PGPR) from halophytic plants enhance under saline conditions. Here, report effect five PGPR consortia halophytes on eight (alfalfa, flax, maize, millet, rice, strawberry, sunflower, wheat) crops most commonly produced salinized soils To test...
Polyploid plants often display functional trait values distinct from those of diploids, influencing their stress tolerance and adaptive capacity. These differences shape how polyploids interact with environment, a factor that is crucial to evolutionary success. Here, we investigated the species complex Dianthus broteri, where ploidy level known correlate water availability, as model system understand possible link between whole-plant relations. We quantified allocation leaves, xylem, roots...
Many halophytic physiological traits related to the tolerance of plants salinity excess have been extensively studied, with a focus on biomass and/or gas exchange parameters. To gain more complete understanding whether affects performance halophytes, an experiment was performed using halophyte Atriplex halimus L. as model. A. were subjected two treatments (171 and 513 mM NaCl) over 60 days in controlled environment. After this period, dry biomass, specific stem conductivity, water potential...
Whole-genome duplication and post-polyploidization genome downsizing play key roles in the evolution of land plants; however, impact genomic diploidization on functional traits still remains poorly understood. Using Dianthus broteri as a model, we compared ecophysiological behaviour colchicine-induced neotetraploids (4xNeo) to diploids (2x) naturally occurring tetraploids (4xNat). Leaf gas-exchange chlorophyll fluorescence analyses were performed order asses what extent evolutionary...
Abstract The evolution of the leaf economics spectrum (LES) is known to be constrained by genetic relatedness but also promoted at small geographical and phylogenetic scales. In those cases, we hypothesized that polyploidy would play a prominent role as an outstanding source functional divergence adaptive potential. We registered leaf‐level nutrient, water‐ light‐economy‐related traits from LES well edaphic properties in four cytotypes autopolyploid Dianthus broteri complex (2×, 4×, 6× 12×)....
Abstract Increasing evidence supports a major role for abiotic stress response in the success of plant polyploids, which usually thrive harsh environments. However, understanding ecophysiology polyploids is challenging due to interactions between genome doubling and natural selection. Here, we investigated physiological responses, gene expression, epiphenotype two related Dianthus broteri cytotypes—with different duplications (4× 12×) evolutionary trajectories—to short extreme temperature...
The research on the plant population metal intra-specific tolerance variability is of paramount importance for design phytoremediation restoration. aim this study was to asses if any exists in copper stress response during seed germination and seedling development Juncus acutus depending provenance habitat. Our results showed that J. were able germinate until Cu concentration 23 mM Cu, but at 15 final percentage 100 68% seeds derived from polluted area 86 40% those collected non-polluted...
Summary Even within those polyploid plant species that become established initially, only a few persist in the long term. Competitive interactions between polyploids and their ancestral cytotypes secondary contact zones can contribute to local extinctions. Environmental factors such as water availability functional trait divergence may influence these interactions. We conducted greenhouse competition experiment with four (2x, 4x, 6x, 12x) of Dianthus broteri under two contrasting irrigation...
