Despite the role of polyploidy in multiple evolutionary processes, its impact on plant diversification remains controversial. An increased polyploid frequency may facilitate speciation through shifts ecology, morphology or both. Here we used Allium to evaluate: (1) relationship between intraspecific and species rate; (2) whether this process is associated with habitat and/or trait shifts. Using eight plastid nuclear ribosomal markers, built a phylogeny 448 species, representing 46% total. We...
In contrast to positive selection, which reduces genetic variation by fixing beneficial alleles, balancing selection maintains within a population or species and plays crucial roles in adaptation diverse organisms. However, genes, genome-wide, are under the extent these genes involved largely unknown. We performed genome-wide scan for across two plant species, Arabidopsis thaliana its relative Capsella rubella, diverged about 8 million generations ago. Among hundreds of with shared...
De novo genes, which originate from ancestral nongenic sequences, are one of the most important sources protein-coding genes. This origination process is crucial for adaptation organisms. However, how de genes arise and become fixed in a population or species remains largely unknown. Here, we identified 782 model plant Arabidopsis thaliana divided them into three types based on availability translational evidence, transcriptional neither nor evidence their origin. Importantly, by integrating...
Organisms need to adapt keep pace with a changing environment. Examining recent range expansion aids our understanding of how organisms evolve overcome environmental constraints. However, climate changes is crucial biological question that still largely unanswered. The plant Arabidopsis thaliana an excellent system study this fundamental question. Its origin in the Iberian Peninsula and North Africa, but it has spread Far East, including most south-eastern edge its native habitats, Yangtze...
Rorippadaguanensis W.Zhang & K.Zhao (Brassicaceae), a new species from Anhui and Hubei Provinces of eastern China, is described. Its floral morphology resembles R.dubia, with its fruit similar to R.cantoniensis. However, it can be readily distinguished R.dubia by inconspicuous stems, oval silicle R.cantoniensis the absence petals bracts on flowers. The complete plastid genome this 155,594 bp in length. Phylogenetic analyses, based whole sequences Rorippa species, revealed that R.daguanensis sister
Background and Aims The identification of stoichiometric homeostasis is crucial for understanding plant adaptive strategies under a changing environment. However, current knowledge has mainly been obtained from mature leaves, with little other organs across different developmental stages. Methods We conducted greenhouse nitrogen (N) phosphorus (P) addition experiment to evaluate the strength stages Arabidopsis thaliana. Key Results Homeostatic regulation coefficients (H) N (HN), P (HP) :...
Flowering time is an adaptive life history trait. Capsella rubella, a close relative of Arabidopsis thaliana and young species, displays extensive variation for flowering but low standing genetic due to extreme bottleneck event, providing excellent opportunity understand how phenotypic diversity can occur with limited initial gene pool. Here, we demonstrate that common allelic parallel evolution at the FLC locus confer in C. rubella. We show two overlapping deletions 5' untranslated region...
Polyploids contribute substantially to plant evolution and biodiversity; however, the mechanisms by which they succeed are still unclear. According polyploid adaptation hypothesis, successful polyploids spread repeated adaptive responses new environments. Here, we tested this hypothesis using two tetraploid yellowcresses (Rorippa), endemic Rorippa elata widespread palustris, in temperate biodiversity hotspot of Hengduan Mountains. Speciation modes were resolved phylogenetic modeling 12...
Aims Arabidopsis thaliana, a widely used model organism in plant biology, is an ideal to test the growth rate hypothesis (GRH) and homeostasis theory about nutrition. Our objectives are i) whether GRH applies this species, ii) how leaf nitrogen (N) phosphorus (P) of A. thaliana follow iii) allometric relationship between N P content consistent with 3/4 power function (N-P ) for individual species. Methods Based on pot experiment phytotron fertilizer additions, we measured car- bon (C),...
Abstract Aim Long‐distance dispersal (LDD) plays an important role in shaping the distribution of global biodiversity. Polyploidy could favour invasion and thereby facilitate LDD. However, how to what extent polyploidy interacts with LDD remain unclear. Here, we test putative a cosmopolitan genus Rorippa . Location Global. Time Period Late Miocene present. Major Taxa Studied Scop., Brassicaceae. Methods We traced biogeographical speciation history for 17 diploids 41 polyploids using...
A new species of genus Rorippa, R. hengduanshanensis, from the Hengduan Mountains, is described herein. Comparing floral structure and overall fruit morphology hengduanshanensis with similar taxa (e.g., benghalensis, dubia, indica) revealed a series morphological differences, both qualitative quantitative. differs benghalensis in ebracteate racemes; dubia flattened silique, presence four petals ploidy level (2n=6x=48); indica uniseriate seeds. Phylogenetic analyses using three plastid...
Abstract Global climate change poses a severe threat to mountain biodiversity. Phenotypic plasticity and local adaptation are two common strategies for alpine plant cope with such change. They may facilitate organismal contrasting environments, depending on the influences of environment or genotype their interacted effects. In this study, we use an endemic (Rorippa elata) in Hengduan mountains (HDM) unravel its phenotypic basis strategy evaluate relative contributions phenotype. We...
Genome size exhibits substantial variation across organisms, but the underlying causes and ecological consequences remain unclear. While interspecific comparisons have suggested selective pressures against large genomes, intraspecific has been less explored. Here, we investigate genome within hexaploid yellowcress herb, Rorippa indica, by integrating flow cytometry, plastomic phylogeography, genomic repeat profiling, reciprocal common garden experiments. We analyzed 192 accessions from 83...
Aim:The strategies of reproductive adaptation for alpine plants have long been a hot topic in evolutionary ecology, but there is still lack quantitative measures traits under natural conditions.Here, we investigated Rorippa elata, an endemic Brassicaceae species one the world's temperate biodiversity hotspots, Hengduan Mountains (HDM).Methods: We established field-based common garden experiment at Shangri-La Alpine Botanical Garden Yunnan.During 2019-2020, transplanted total 633 R. elata 150...
