Insect-resistant transgenic Pinus radiata

Plant Cell Reports, 2005
Transgenic radiata pine (Pinus radiata D. Don) plants containing a Bacillus thuringiensis (Bt) toxin gene, crylAc, were produced by means of biolistic transformation of embryogenic tissue. Using the selectable marker gene nptII and corresponding geneticin selection, 20 independent transgenic lines from five genotypes were established.

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.

Chloride efflux along Pinus radiata roots.

Nature, 1968
PREVIOUS investigations of differences in nutrient uptake along plant roots occurring during short intervals of time have recorded sites of influx, but to obtain net flux it is also necessary to study efflux1. This has been done in current studies of ion uptake along roots of Pinus radiata seedlings, and findings on the loss of chloride at different ...

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 ...

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 ...

Epicuticular wax of Pinus radiata needles

Phytochemistry, 1978
Abstract Epicuticular wax isolated from the cotyledons and primary needles of 10-week-old Pinus radiata seedlings is similar in composition and contains 86% neutral compounds, viz. alkyl esters (25%, C 24 –C 64 ), nonacosan-10-ol (52%), heptacosane-5,10-diol (2%), nonacosane-4,10-diol, nonacosane-5,10-diol, and nonacosane-10,13-diol (total 12%) and

Terpene variability of mainland Pinus radiata

Biochemical Systematics and Ecology, 1992
Abstract Wood and foliage mono- and sesquiterpenes of 45 Pinus radiata trees from the three native mainland populations in California were analysed using conventional and chiral gas chromatography. The wood was found to contain no detectable sesquiterpenes. Wood monoterpenes mainly consisted of β-pinene [98.5% (−), 1.5% (+)] and variable ratios of (
