Podocarpaceae

open access: yes, 1984
Monoecious or dioecious trees and shrubs, some prostrate (and one parasitic on another member of the family, Parasitaxus, in New Caledonia). Each cotyledon, of which there are usually two but in a few cases more, a fused pair with a corresponding bifid tip.

In search of lost time: tracing the fossil diversity of Podocarpaceae through the ages [PDF]

open access: yes, 2023
The Podocarpaceae are a morphologically diverse conifer family that have a cryptic fossil record reported since the Permian. We reviewed the fossil record of Podocarpaceae, tested the affinities of its oldest records using phylogenetic analyses, compiled

Phylogeny and divergence times of gymnosperms inferred from single-copy nuclear genes. [PDF]

open access: yesPLoS ONE, 2014
Phylogenetic reconstruction is fundamental to study evolutionary biology and historical biogeography. However, there was not a molecular phylogeny of gymnosperms represented by extensive sampling at the genus level, and most published phylogenies of this

The complete chloroplast genome sequence of Podocarpus neriifolius (Podocarpaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete chloroplast (cp) genome sequence of Podocarpus neriifolius D. Don was determined by BGISEQ-500 platform sequencing in this study. The entire cp genome was determined to be 133,878 bp in length.

Paleovegetational Reconstruction and Implications on Formation of Oil Shale and Coal in the Lower Cretaceous Laoheishan Basin (NE China): Evidence from Palynology and Terpenoid Biomarkers

open access: yesEnergies, 2021
In some cases, the oil shale deposited in shallow lakes may be genetically associated with the coal-bearing successions. Although paleovegetation is an important controlling factor for the formation of oil shale- and coal-bearing successions, few studies

The complete chloroplast genome sequence of Podocarpus imbricatus (Podocarpaceae) and its phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2019
In this study, the complete chloroplast genome sequence of Podocarpus imbricatus (Podocarpaceae) was determined. Like other chloroplast genomes in conifers, the Podocarpus imbricatus genome did not have typical quadripartite structure. The genome was 133,

Flavonoids and Phenolic Compounds From the Parasitic Gymnosperm Endemic to New Caledonia

open access: yesNatural Product Communications, 2022
Parasitaxus usta (Podocarpaceae) is the only parasitic gymnosperm and endemic to New Caledonia. In this survey, 11 flavonoids and 6 phenolic compounds were isolated from the aerial parts.

An enigmatic tropical conifer from the Early Cretaceous of Gondwana [PDF]

open access: yesActa Palaeontologica Polonica
We describe a new genus of Leliacladus Batista & L.Kunzmann with the type species Leliacladus (Brachyphyllum) castilhoi (Duarte, 1985) Batista & L.Kunzmann gen. nov. et comb.
