A two-photon fluorescence micro-spectroscopy method for chemotaxonomic characterization of fossil resins. [PDF]

Appl Plant Sci
Abstract Premise Amber, a fossilized chemical defensive exudate, is important for understanding ancient plant–insect/pathogen interactions, yet its botanical origins, especially for Cretaceous amber, remain enigmatic. Here, we develop and apply a fluorescence micro‐spectroscopy approach within the context of a larger study on the provenance of amber ...

Seed-cone architecture of Pararaucaria utahensis Gee, Howell et Dayvault sp. nov. (Cheirolepidiaceae) from the Upper Jurassic Morrison Formation of Utah, USA. [PDF]

Am J Bot
Abstract Premise Although Pararaucaria seed cones were first described 90 years ago, only in the last dozen years have we discovered the greater extent of the species diversity and paleogeographic range of the genus. Pararaucaria is now known across the mid‐latitudes of the Lower Jurassic to Lower Cretaceous in the northern and southern hemispheres ...

Leaf Size in Conifers: Global Associations With Climate and Evolutionary History. [PDF]

Glob Chang Biol
Global patterns in leaf size are linked to climatic trade‐offs, so we explore these relationships in a major group of plants, the conifers. Using contemporary phylogenetic methods, we show that conifers display a strong pattern of evolutionary conservatism in the association of leaf size with climate, and highlight that these relationships are driven ...

Distinct root-associated fungal communities may account for the persistence of Podocarpus conifers in tropical forest. [PDF]

Ecology
Abstract Podocarps (Podocarpaceae) are one of the few lineages of conifers found in closed canopy tropical forests. They typically have highly restricted distributions that are associated with nutrient‐poor sites. Unlike other tree species, the presence of distinct nodule‐like structures allows their roots to be easily distinguished from those of co ...

Drought avoidance and vulnerability in the Australian Araucariaceae [PDF]

Tree Physiology, 2015
The Araucariaceae is an iconic tree family. Once globally important, the Araucariaceae declined dramatically over the Cenozoic period. Increasing aridity is thought to be responsible for extinction and range contraction of Araucariaceae in Australia, yet little is known about how these trees respond to water stress.

Novel and Conserved miRNAs Among Brazilian Pine and Other Gymnosperms

Frontiers in Genetics, 2019
The knowledge about plant miRNAs has increased exponentially, with thousands of miRNAs been reported in different plant taxa using high throughput sequencing technologies and bioinformatic tools.

Phylogenetic biogeography of Araucaria (Araucariaceae)

Проблемы ботаники южной сибири и монголии, 2020
The analysis of molecular data of all 19 recent species of the genus Araucaria Juss. (Araucariaceae) wascarried out and original cladogramm was build. Based on the cladogramm, the map of correlations of the phylogeneticrelationships and the distribution of all recent Araucaria species is proposed.

Revealing the diversity of amber source plants from the Early Cretaceous Crato Formation, Brazil

BMC Evolutionary Biology, 2020
Background Amber has been reported from the Early Cretaceous Crato Formation, as isolated clasts or within plant tissues. Undescribed cones of uncertain gymnosperm affinity have also been recovered with amber preserved in situ.

Evolutionary diversification of new Caledonian Araucaria.

PLoS ONE, 2014
New Caledonia is a global biodiversity hotspot. Hypotheses for its biotic richness suggest either that the island is a 'museum' for an old Gondwana biota or alternatively it has developed following relatively recent long distance dispersal and in situ ...
