Fossil records of subsection Pinus (genus Pinus, Pinaceae) from the Cenozoic in Japan

Journal of Plant Research, 2014
Extant pines of subsection Pinus (section Pinus, genus Pinus, Pinaceae) are predominantly distributed in Eastern Asia. However, the extent of diversification in the section has yet to be fully clarified. We reviewed fossil records of subsection Pinus from Japan and collected permineralized materials, in which anatomical details are preserved for better

Biosystematics of the genus Pinus, subsection contortae

Biochemical Systematics and Ecology, 1983
Gene frequency data from 42 isoenzyme loci were used to assess the phylogeny of taxa in the genus Pinus, subsection Contortae. The classification inferred from a phenogram based on Nei's genetic distance measure (DN) was generally in good agreement with the current taxonomic treatment of the subsection.

Chemosystematic studies in the genus Pinus: the leaf oil of Pinus contorta var. latifolia

Canadian Journal of Botany, 1971
Gas chromatographic analysis of the volatile oil of the leaf oil of lodgepole pine from the Rocky Mountains showed 1-β-phellandrene (34%) and 1-β-pinene (30.5%) as major components. Lesser amounts of α-pinene (6.5%), myrcene (3%), cis-ocimene (2.5%), 3-carene (1.5%), terpinolene (1%), γ-terpinene (0.3%), α-terpineol (4%), terpinen-4-ol (0.5 ...

Comparative mapping among subsectionAustrales(genusPinus, family Pinaceae)

Genome, 2008
Comparative mapping in conifers has not yet been used to test for small-scale genomic disruptions such as inversions, duplications, and deletions occurring between closely related taxa. Using comparative mapping to probe this smaller scale of inquiry may provide clues about speciation in a phylogenetically problematic taxon, the diploxylon pine ...

The genus Pinus

1998
More than 40 species belonging to the genus Pinus are present in Italy, though most of them are non-native species of low interest in forestry. A large amount of information is available in literature for most of the native pine species with trans-european natural range (i.e., Pinus sylvestris).

Genome size and environmental factors in the genus Pinus

American Journal of Botany, 1993
Nuclear 1C DNA content in haploid megagametophyte tissue of 18 North American and one exotic Pinus species was determined using scanning microspectrophotometry. The nuclear DNA content in root meristematic cells of Zea mays L. ssp. mays, inbred line Va35 (4C = 10.31 pg) was used as a standard. DNA content measured by microspectrophotometry was verified

Three Species of Genus Pinus Suitable as Bioindicators of Polluted Environment

Water, Air, and Soil Pollution, 1998
The long-term study objective was to determine the suitability of selected species of genus Pinus (Pinus sylvestris, Pinus nigra and Pinus mugo) for use as bioindicators of environmental pollution. In these experiments a new methodology of evaluation of mitotic abnormalities was established and its potential for common use tested.
