A chromosome-level genome of a Kordofan melon illuminates the origin of domesticated watermelons.
Wild progenitors of crops are important resources for breeding and for understanding domestication, but identifying them is difficult. Using an integrative approach, we discovered that a Sudanese form of melon with nonbitter whitish pulp, known as the Kordofan melon, is the closest relative of domesticated watermelons and a possible progenitor.... -

Genome sequencing of up to 6,000-yr-old Citrullus seeds reveals use of a bitter-fleshed species prior to watermelon domestication.
Iconographic evidence from Egypt suggests that watermelon pulp was consumed there as a dessert by 4,360 BP. Earlier archaeobotanical evidence comes from seeds from Neolithic settlements in Libya, but whether these were watermelons with sweet pulp or other forms is unknown. We generated genome sequences from 6,000- and 3,300-yr-old seeds... -

Revised Species Delimitation in the Giant Water Lily Genus Victoria (Nymphaeaceae) Confirms a New Species and Has Implications for Its Conservation.
Reliably documenting plant diversity is necessary to protect and sustainably benefit from it. At the heart of this documentation lie species concepts and the practical methods used to delimit taxa. Here, we apply a total-evidence, iterative methodology to delimit and document species in the South American genus (Nymphaeaceae). The systematics... -

Plastome Evolution in the Hyperdiverse Genus Euphorbia (Euphorbiaceae) Using Phylogenomic and Comparative Analyses: Large-Scale Expansion and Contraction of the Inverted Repeat Region.
With 2,000 species, is one of the largest angiosperm genera, yet a lack of chloroplast genome (plastome) resources impedes a better understanding of its evolution. In this study, we assembled and annotated 28 plastomes from Euphorbiaceae, of which 15 were newly sequenced. Phylogenomic and comparative analyses of 22 plastome sequences... -

Botanical Monography in the Anthropocene
Botanical monographs have been the gold standard for communicating comprehensive systematic information about plants for over 300 years. Monographs catalyse species discovery, biodiversity documentation and conservation, and facilitate downstream research on wild and cultivated plant species. Increased availability of DNA sequence data and digitised resources now provide powerful resources for...Grace, Olwen M. ; Pérez-Escobar, Oscar A. ; Lucas, Eve J. ; Vorontsova, Maria S. ; Lewis, Gwilym P. …

Repetitive DNA Restructuring Across Multiple Nicotiana Allopolyploidisation Events Shows a Lack of Strong Cytoplasmic Bias in Influencing Repeat Turnover
Allopolyploidy is acknowledged as an important force in plant evolution. Frequent allopolyploidy in Nicotiana across different timescales permits the evaluation of genome restructuring and repeat dynamics through time. Here we use a clustering approach on high-throughput sequence reads to identify the main classes of repetitive elements following three allotetraploid events,...
