Phosphorylated intermediates of terpene biosynthesis in Pinus radiata
Archives of Biochemistry and Biophysics, 1966Abstract Isolated needles of Pinus radiata incorporate radioactive orthophosphate into ATP, pyrophosphomevalonic acid, and isopentenyl pyrophosphate. Radioactivity from 2-C14-labeled mevalonic acid was found in the last two compounds and in phosphomevalonic acid when an extract from Pinus seedlings was used.

Thermal acclimation of respiration but not photosynthesis in Pinus radiata
Functional Plant Biology, 2008Pinus radiata L. were grown in climate-controlled cabinets under three night/day temperature treatments, and transferred between treatments to mimic changes in growth temperature. The objective was to determine the extent to which dark respiration and photosynthesis in pre-existing and new needles acclimate to changes in growth temperatures.

Occurrence and inheritance of microsatellites in Pinus radiata
Genome, 1994Microsatellites are an important class of DNA marker because of their abundance and length hypervariability. As part of a project mapping the Pinus radiata genome, we have characterized some of the microsatellites in this species. Southern blots were screened with oligonucleotide probes [(CA)10, (GA)10, (GAA)9, (CAA)8, (CAC)5, (GACA)4] to assess their

Tracheid differentiation in Pinus radiata
Wood Science and Technology, 1977Differentiating tracheids in Pinus radiata D. Don have been examined with the electron microscope. Despite the fact that one of the major differentiation processes is cellulose formation, little ultrastructural evidence has been found to indicate how this occurs. On the other hand, there is ample evidence of the incorporation of non-cellulosic material

MICROFIBRIL ANGLES IN THE ROOT WOOD OF PINUS RADIATA AND PINUS NIGRA
IAWA Journal, 2001Microfibril angles of the S2 layer and tracheid lengths were measured in the root wood of Pinus nigra, and the root and stem wood of Pinus radiata. Within 10 mm (the first 2–3 growth rings) from the root centre, microfibril angles were large in the wood of both species, ranging from 25° to 40°.

Resistance of Pinus densiflora and Pinus rigida × radiata to Fomes annosus
European Journal of Forest Pathology, 1979AbstractThe stemwood of Pinus densiflora was found to be more resistant than the stemwood of Pinus rigida × radiata in inhibiting the decaying activity and linear growth of Fomes annosus. The chemical factors responsible for the variations in resistance were extractable in chloroform. One fraction isolated from the chloroform extract of P.

Genetic Transformation of Pinus radiata
2000Pinus radiata is the main forest tree species planted in commercial forestry in New Zealand and has been grown for more than 100-years. It was originally introduced from California and an intensive tree improvement program, which started in the early 1950s, has concentrated on better growth rate, stem form, and lack of stem cones on the lower stem ...

Cold Hardiness of Radiata Pine (Pinus radiata D. Don)
2001Pinus radiata D. Don is native to North America, with three mainland populations on the coast of central California and two island populations off the coast of Baja California, Mexico (Scott 1960). The species occupies only about 7,000 ha in its natural habitat and is of little commercial significance (Burdon and Miller 1992), except to the Christmas ...

A xyloglucan in etiolated seedlings of Pinus radiata
Phytochemistry, 1997Abstract The changes in cell wall carbohydrates and starch were investigated in hypocotyls and cotyledons during growth of etiolated seedlings of Pinus radiata. Starch was depleted within two weeks with an accompanying rise in a hemicellulosic xyloglucan component. This was purified by fractional precipitation.

Carbohydrate Metabolism in the Sapwood of Pinus radiata
Nature, 1963THE use of carbon-14 produced in nuclear bomb testing in biological investigation has been discussed in an earlier communication1. Since 1954 the specific activity of the carbon dioxide in the atmosphere over New Zealand has been increasing, as is shown in Fig. 1 2. We have used this effect to examine the carbohydrate metabolism of Pinus radiata.
