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

Journal 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

Beneficial Effects of a Root-Endophytic Bacterium with Quorum-Sensing Traits on Growth and Drought Tolerance in the Vulnerable Conifer Araucaria araucana

Plants
Climate change-induced drought threatens the persistence of Araucaria araucana, an endangered and endemic conifer of the Southern Andes. Beneficial plant–microbe interactions may contribute to drought resilience.
