“…In fact, stems exposed to 1 mg ethephon exhibited an abnormal layer of unlignified tissue in the outer xylem (asterisk in Figure 4B). This corroborates the down-regulation of a cohort of genes identified via the microarray that are associated with lignin biosynthesis in the xylem which is consistent with a previous claim that ethephon reduced lignification of tracheids in compression wood that developed on the underside of tilted stems of Pinus densiflora (Yamamoto and Kozlowski 1987b).…”

Background: The design, construction and application of a Pinus microarray platform are described. The oligonucleotide microarray was developed using publicly available Pinus cDNA sequences mostly derived from Pinus taeda to test whether heterologous hybridisation of microarray probes will generate useful data when hybridised with cRNA constructed from the dominant New Zealand forestry species Pinus radiata.

“…Ethephon reduced lignification of tracheids in compression wood that developed on the underside of tilted stems of Pinus densiflora Siebold & Zucc. (Yamamoto and Kozlowski 1987b). In P. halepensis, ethephon application implicated ethylene in the control of resin duct formation (Yamamoto and Kozlowski 1987a).…”

“…Waterlogged soils increased stem diameter growth more as a result of increasing bark thickening and stem hypertrophy, which then cause xylem increment. The increase in bark thickness was associated with accelerated proliferation of phloem parenchyma cells and large amounts of intercellular space in the phloem (Yamamoto and Kozlowski, 1987).…”

The study was carried out for investigation of the adaptability of white jabon seedlings from 12 populations to drought and water logging stresses in a controlled green house. The results showed that the adaptive responses of white jabon seedling to drought and waterlogging stresses were affected by genotype (population). The drought and waterlogging stresses significantly inhibited plant growth, biomass accumulation and allocation, leaf area, also decreased chlorophyll content, increased carotenoids contents, and accumulated free proline. Relative water content and specific leaf area tended to be higher in waterlogging and declined in drought stresses. The result clearly indicated that white jabon seedlings were more adaptive to waterlogging than to drought stresses. Moreover, there were different responses to drought and waterlogging stresses between the twelve populations. Kampar, Gowa, Kuala Kencana and OKI populations exhibited higher growth performance and stress tolerance index to be adapted to waterlogging stress, while Gowa, Pomalaa and Kampar populations had relatively better growth performance in the drought stress.

“…The formation of tracheids on the surface probably indicates that low concentrations of auxin reached the surface parenchyma cells. Yamamoto & Kozlowski (1987b) found an increase in endogenous ethylene concentrations following flooding, which resulted in an increase in tracheid number. In our study the trend towards increasing tracheid numbers induced by ethrel, was curtailed by Ag# + and restored to the value induced by 0.1% NAA, indicating that the promoting effect of ethylene on tracheid formation can be blocked by its action inhibitor.…”

Role of ethylene and auxin in regenerative differentiation and orientation of tracheids in Pinus pinea seedlings

A low auxin concentration (0.1% naphthalene acetic acid) induced tracheids with longitudinal polarity parallel to the hypocotyl axis in young Pinus pinea seedlings. Application of 0.1% ethrel laterally and 0.1% naphthalene acetic acid apically disturbed axial tracheid polarity and promoted the differentiation of tracheids with a lateral orientation. Ethrel by itself, with no auxin background, did not affect tracheid differentiation. Apical application of 1% gibberellic acid with the low auxin, reversed the polarity disorder induced by ethrel. Disturbance of axial tracheid polarity was observed under a high auxin concentration (0.5% naphthalene acetic acid) which was similar to the combined effect of ethrel and auxin. The high auxin concentration increased tracheid number significantly. This effect was curtailed following treatment with inhibitors of ethylene formation (Co# + ; 1-aminoethoxyvinylglycine) and action (Ag# + ). The role of ethylene in controlling the differentiation of radial tracheids, which characterize the vascular rays of pines, is discussed.
