Novel phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon Gothan reveals close affinity with extant Podocarpaceae (Coniferales)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 2, Page 469-478, March 2025.
We perform a phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon to understand the systematic relationship with extant conifers. Data come from four nucleotide regions (trnL‐F, trnK‐matK, rbcL, psbA‐trnH), xylological characters, and biomolecular composition of five extant conifer families and extinct Xenoxylon. Using maximum parsimony in

Convergent Patterns of Karyotype Evolution Underlying Karyotype Uniformity in Conifers

open access: yesAdvanced Science, Volume 12, Issue 7, February 17, 2025.
The remarkable karyotype uniformity observed in gymnosperms has long posed an evolutionary puzzle. This study proposes a model of karyotype evolution in gymnosperms, highlighting the rarity of both polyploidy and dysploidy as key factors underlying this uniformity.

Naturally‐occurring nematicides of plant origin: two decades of novel chemistries

open access: yesPest Management Science, Volume 81, Issue 2, Page 540-571, February 2025.
A review of structure–activity correlations for 262 plant‐derived nematicidal compounds for controlling plant parasitic nematodes is presented. Chemical structures, sources, and isolation procedures are summarized based on the major chemical groups. Abstract Plant‐parasitic nematodes are among the most destructive plant pathogens, resulting in a global
