Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, EarlyView.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Tandemly duplicated TaERF109 genes confer drought tolerance and post‐drought recovery in wheat

open access: yesJournal of Integrative Plant Biology, EarlyView.
Tandemly duplicated TaERF109 transcription factor genes in wheat modulate growth traits and enhance drought tolerance by regulating the TaMADS56 transcription facto gene, cytokinin biosynthesis‐related genes, and nicotianamine synthase genes, revealing the critical role of tandemly duplicated genes in the coordination of stress responses and ...

Citrus breeding for biotic and abiotic stress tolerances; new tools and strategies for biodiversity Mobilization : S04T01 [PDF]

open access: yes, 2013
Citrus industry is affected worldwide by several fungal, bacterial and viral diseases. Some production areas also suffer of strong abiotic constraints such as water deficit, salt stress and iron chlorosis. Resistance or tolerance traits for most of these

Regional Genetic Structure in the Aquatic Macrophyte Ruppia cirrhosa Suggests Dispersal by Waterbirds [PDF]

open access: yes, 2017
The evolutionary history of the genus Ruppia has been shaped by hybridization, polyploidisation and vicariance that have resulted in a problematic taxonomy. Recent studies provided insight into species circumscription, organelle takeover by hybridization,

Origins, colonization, and lineage recombination in a widespread perennial soybean polyploid complex [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Polyploidy is a dominant feature of flowering plant genomes, including those of many important crop species, implying that polyploidy confers evolutionary advantages on plant species. Recent molecular studies suggest that polyploids often originate many times from the same progenitor diploids. For this to provide a broader genetic base for

PanGraphRNA: An efficient and flexible bioinformatics platform for graph pangenome‐based RNA‐seq data analysis

open access: yesJournal of Integrative Plant Biology, EarlyView.
PanGraphRNA is an easy‐to‐use platform that improves RNA‐seq analysis by using graph pangenomes instead of a single reference genome. It increases read alignment accuracy, detects important genes missed by traditional methods, and works across major crops, helping researchers obtain more reliable transcriptome results for diverse plant research and ...

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

open access: yesNew Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...

Bringing together evolution on serpentine and polyploidy: spatiotemporal history of the diploid-tetraploid complex of Knautia arvensis (Dipsacaceae).

open access: yesPLoS ONE, 2012
Polyploidization is one of the leading forces in the evolution of land plants, providing opportunities for instant speciation and rapid gain of evolutionary novelties.
