Pine (Pinus radiata)

2006
This chapter describes the transformation of Pinus radiata using organogenic cotyledon explants rather than the more common somatic embryogenesis methods for conifers. The advantages of our method are the year round availability of seed and that over 80% of genotypes can be easily regenerated from the mature cotyledon explants.

The origin and genetic diversity of Pinus radiata in Australia

Theoretical and Applied Genetics, 1987
Despite the fact that forest trees are in early stages of domestication there has been little direct evaluation of either the origin of, or genetic diversity within the breeding material in tree improvement programs. Allozyme variation was used to compare the total genetic diversity in the breeding programs of P.

Phosphorylated intermediates of terpene biosynthesis in Pinus radiata

Archives of Biochemistry and Biophysics, 1966
Abstract 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, 2008
Pinus 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.

Tracheid differentiation in Pinus radiata

Wood Science and Technology, 1977
Differentiating 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

Genetic Transformation of Pinus radiata

2000
Pinus 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 ...

Occurrence and inheritance of microsatellites in Pinus radiata

Genome, 1994
Microsatellites 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

MICROFIBRIL ANGLES IN THE ROOT WOOD OF PINUS RADIATA AND PINUS NIGRA

IAWA Journal, 2001
Microfibril 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, 1979
AbstractThe 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.

Cold Hardiness of Radiata Pine (Pinus radiata D. Don)

2001
Pinus 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 ...
