Edaphic isolation as a driver of divergence in a new Amazonian species of Diclinanona (Annonaceae)

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract For many years a mysterious collection made during an expedition to Venezuelan Amazonia in 1992 was in a folder at the former Utrecht Herbarium as “unidentified Annonaceae”. Several different genera were suggested for identification but since flowers were lacking it was unclear where this taxon should be placed. One of the suggestions based on

The liverwort genus Metzgeria (Jungermanniopsida) in Europe – An integrative taxonomic update

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Species delimitation in liverworts, such as Metzgeria, is hampered by their limited morphology and hence morphologically determined specimens often turn out to belong to other taxa using molecular data. Metzgeria is a simple thalloid liverwort genus with over 100 species and a worldwide distribution. Seven species are listed to occur in Europe.

A phylogenomic analysis and revised infrageneric classification of Thesium (Santalaceae)

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract A phylogenomic analysis and revised infrageneric classification of Thesium (Santalaceae) is presented based on targeted enrichment using the Angiosperms353 probe set. This first targeted sequencing study includes 137 samples representing 106 species (approximately 32% of the genus).

Genetic architecture of phenological, morphological, and phytochemical traits in Cannabis landraces

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Despite its long history of cultivation and diverse applications, Cannabis sativa remains underexplored at the genomic level, particularly in landrace populations that harbor untapped genetic diversity. In this study, we investigated the genetic architecture of 145 Iranian cannabis landrace accessions, including both male and female plants ...

Genetic dissection and transcriptomic analysis of a novel high‐tillering phenotype in rice derived from weedy rice (Hapcheonaengmi3) and Tongil‐type Rice (Milyang23)

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Rice (Oryza sativa L.) tillering is a critical determinant of grain yield, yet the genetic mechanisms underlying non‐productive tillers remain poorly understood. Here, we report a novel high‐tillering (HT) phenotype derived from a cross between the elite cultivar Milyang23 and weedy rice Hapcheonaengmi3. The HT phenotype was absent in parental
