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 ...

Transcriptome of Xenopus andrei, an octoploid frog, during embryonic development

open access: yesData in Brief, 2018
Although polyploidy occurs throughout the fish and amphibian lineages, the Xenopus genus exhibits a high incidence of polyploidy, with 25 out of the 26 known species being polyploid. However, transcriptomic information is currently available for only one

HSP101‐encoding NEO‐TETRAPLOID RICE FERTILITY GENE 1 regulates tapetum development through interaction with SAPK2 in polyploid rice

open access: yesJournal of Integrative Plant Biology, EarlyView.
In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

The annotated blueprint: integrated functional genomic resources for a model tetraploid wheat Triticum turgidum cv Kronos

open access: yesNew Phytologist, EarlyView.
Summary Triticum turgidum cv Kronos is a tetraploid wheat cultivar that underpins one of the most widely used community platforms for functional genomics. Over the past decade, researchers have generated c. 3000 exome‐capture (EC) and promoter‐capture (PC) datasets linked to mutagenized seed stocks, along with extensive transcriptomic and phenotypic ...

Recombination suppression in plant adaptation and speciation

open access: yesNew Phytologist, EarlyView.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Potential benefits of male diploidy and female triploidy for parasitoid wasps used as biological control agents: A case study in Nasonia

open access: yesBiological Control
Parasitoid wasps are haplodiploid insects, but polyploidy (diploid males, triploid females) occurs for many species. In biological control, polyploidy may have beneficial effects on desirable biological related traits.

Polyploidy in Gymnosperms [PDF]

open access: yesEvolution, 1959
The gymnosperms constitute a primitive group of seed plants which have a considerable evolutionary interest. A substantial amount of literature on the morphology of the group exists, but very little has been written about the various cytogenetic factors responsible for evolution within the group.

Transmembrane Protein GbTMEM209 Inhibits Fibre Elongation via Competitive Interaction With GbHOX3 in Gossypium barbadense

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Sea Island cotton (Gossypium barbadense) produces premium‐quality fibres, yet the genetic basis underlying its fibre development remains elusive. Here, we identify two key non‐synonymous single nucleotide polymorphisms (SNPs, G/C and G/A) in the gene Gbar_D13G024080, which encodes the TRANSMEMBRANE PROTEIN 209 (TMEM209). These SNPs resulted in
