  • Whole genome duplication (WGD) presents new challenges to the establishment of optimal allelic combinations and to the meiotic machinery. Here, the authors show that adaptive gene flow from Arabidopsis arenosa could rescue the nascent A. lyrata from extinction following WGD.

  • Relative contributions of pre-existing versus de novo genomic variation to adaptation remain unclear. Here, the authors address this problem by examining the adaptation of autotetraploid Arabidopsis arenosa to serpentine soils and find that both types of variations contribute to rapid adaptation.

  • Cochlearia is an evolutionarily dynamic genus with different base chromosome numbers and ploidal levels. Here, the authors construct a graph-based pangenome for Cochlearia and reveal that whole-genome duplication associated with greater diversity of genomic structural variation and their possible function in adaptation.

  • Baobab is a long-lived tree that holds great economic, ecological, and cultural value. Here, the authors report haploid chromosome-level reference genome of Adansonia digitata and draft assemblies for a sibling tree, two trees from distinct locations in Africa, and a related species from Madagascar.

  • How plant biosynthetic gene clusters (BGCs) form and evolve remains unclear. Here, via examining available genomes within and between Arabidopsis species, the authors show that the thalianol BGC has evolved recently and is still dynamically evolving through involvement of auxiliary genes and chromosomal inversions.

  • Grass pea is a multi-stress tolerant orphan crop and developing cultivars with decreased accumulation of the neurotoxin β-L-oxalyl-2,3-diaminopropionic acid (β-L-ODAP) is one of its breeding objectives. Here, the authors assemble its genome and reveal genes involved in the biosynthesis of β-L-ODAP.

  • Temperature-dependent alternative splicing of FLOWERING LOCUS M (FLM) results in two protein products, FLM-β and FLM-δ, that regulate the onset of flowering in Arabidopsis; at cooler temperatures FLM-β represses flowering, whereas at higher temperatures, the plant preferentially produces FLM-δ, which promotes flowering.

  • Vallejo-Marín et al. combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of Mimulus guttatus from North America to Europe and the Southwest Pacific. They found that M. guttatus was first likely introduced to the British Isles from the Aleutian Islands (Alaska), followed by admixture from multiple parts of the native range, and hypothesise that populations in the British Isles then served as a bridgehead for vanguard invasions worldwide.
