    Notes: Abstract  Allometric relationships between stem, leaf area and crown dimensions were determined for Eucalyptus nitens (Deane and Maiden) Maiden using 81 trees sampled from 13 post-canopy closure sites and 34 trees sampled from 6 pre-canopy closure sites. These sites differed in site quality, stand age, fertiliser treatment, stand density and levels of weed infestation. Overall, tree age ranged from 2 to 13 years, tree height from 1.4 to 26.1 m and diameter at breast height from 0.6 to 38.7 cm. Pre-canopy closure trees exhibited site-specific relationships which were to some extent confounded with tree age. However, post-canopy closure trees had relationships which were independent of site, age and silvicultural treatments. Strong relationships between structural components were found for both stem and crown. Stem diameter at breast height was non-linearly related to tree height and crown length. Stem sapwood area (breast height or crown base) could be predicted from stem cross-sectional area. For post-canopy closure trees, a functional relationship between sapwood area (breast height and crown base) and leaf area was site-independent. The lack of specificity in terms of both site and management techniques enables these relationships to be applied generally to E. nitens plantations in Tasmania.

    Effect of esterification on the absorption of astaxanthin in rainbow trout, Oncorhynchus mykiss (Walbaum) (2002)

    Notes: Gastrointestinal and serum absorption of astaxanthin was studied in rainbow trout, Oncorhynchus mykiss (Walbaum) (217 ± 2 g) fed diets supplemented with either esterified astaxanthin (from Haematococcus pluvialis) or free astaxanthin (synthetic, as 8% w/w beadlets) at similar levels (50 mg kg−1). After 56 days of feeding, there was a significant difference (P = 0.0582) between steady-state serum astaxanthin concentrations for fish fed free (2.0 ±  0.3 μg mL−1) or esterified astaxanthin (1.3 ± 0.1  μg mL−1) at the 90% confidence level. However, following ingestion of a single meal supplemented with free or esterified astaxanthin, the rates of astaxanthin absorption into serum were not significantly different (P 〉 0.1) (0.8 ± 0.2 µg mL−1 h−1 and 1.0 ± 0.4 µg mL−1 h−1 respectively). In fish fed both free or esterified astaxanthin, higher absorption (P 〈 0.05) of astaxanthin by the ileal (0.8 ± 0.14 μg g−1 and 0.9 ± 0.15 μg g−1 respectively) compared with the posterior (0.2 ± 0.01 μg g−1 and 0.3 ± 0.14 μg g−1 respectively) intestine was recorded. This confirmed the role of the anterior intestine in carotenoid absorption. Non-detectable levels of esters in digesta taken from the hind intestine suggest the anterior intestine is also the primary region for ester hydrolysis.

    Productivity, carbon isotope discrimination and leaf traits of trees of Eucalyptus globulus Labill. in relation to water availability (2004)
    Oxford, UK : Blackwell Science Ltd
    Plant, cell & environment 27 (2004), S. 0

    ISSN: 1365-3040
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The stand basal area, carbon isotope discrimination (Δ) in tree rings and leaves, leaf area index and leaf traits of trees were measured in 6- to 8-year-old stands of Eucalyptus globulus Labill. across a gradient of rainfall of 600–1400 mm year−1 in south-western Australia to better understand the importance of leaf traits and gas-exchange as determinants of stand productivity. Δ ranged from 17‰ to 21‰. Δ and basal area were highly, positively correlated with each other and the ratio of mean annual rainfall to potential evaporation (P/PE). Leaf area index, soil water holding capacity and leaf nitrogen content were only weakly correlated with basal area. Δ and P/PE were negatively correlated with leaf nitrogen content. Δ was negatively correlated with leaf density but positively correlated with specific leaf area. This is consistent with the theory that larger leaf nitrogen content and smaller specific leaf area are associated with increased photosynthetic capacity and increased leaf-scale water-use-efficiency, and that Δ is influenced by mesophyll conductance. It is concluded that canopy conductance is a more important determinant of growth in water-limited conditions than either leaf area index or leaf traits in fertilized stands of E. globulus. Water availability was dictated more by rainfall than soil type.

    Control of transpiration in an irrigated Eucalyptus globulus Labill. plantation (2000)
    Oxford, UK : Blackwell Science Ltd
    Plant, cell & environment 23 (2000), S. 0 
    Details

    Topics: Biology
    Notes: Stomatal conductance and transpiration were measured concurrently in an irrigated Eucalyptus globulus Labill. plantation. Canopy stomatal conductance, canopy boundary layer conductance and the dimensionless decoupling coefficient (Ω) were calculated (a) summing the conductance of three canopy layers (gc) and (b) weighting the contribution of foliage according to the amount of radiation received (gc′). Canopy transpiration was then calculated from gc and gc′ for Ω = 1 (Eeq), Ω = 0 (Eimp) and by weighting Eeq and Eimp using Ω (EΩ). Eeq, Eimp and EΩ were compared to transpiration estimated from measurements of heat pulse velocity. The mean value of Ω was 0·63. Transpiration calculated using gc and assuming perfect coupling (12·5 ± 0·9 mmol m−2 s−1) significantly overestimated measured values (8·7 ± 0·8 mmol m−2 s−1). Good estimates of canopy transpiration were obtained either (a) calculating EΩ separately for the individual canopy layers or (b) treating the canopy as a single layer and using gc′ in a calculation of Eimp (Ω = 0). The latter approach only required measurement of stomatal conductance at a single canopy position but would be unsuitable for use in combined models of canopy transpiration and assimilation. It should however, be suitable for estimating transpiration in forests regardless of the degree of coupling.

    The apparent feed-forward response to vapour pressure deficit of stomata in droughted, field-grown Eucalyptus globulus Labill (2004)

    Notes: This study tested a multiplicative model of stomatal response to environment for drought-affected trees of Eucalyptus globulus Labill. growing in southern Australia. The model incorporates a feed-forward response to vapour pressure deficit of ambient air (δea) and performed well if evaluated using reduced major axis regression and log-transformed   data.   There   was   strong   evidence   from gas-exchange data, leaf water potentials and sapflow measurements of the feed-forward response by stomata to leaf-to-air vapour pressure deficit (δel). The response of stomata to δel was irreversible. Stomatal conductance and the rate of net photosynthesis were highly correlated and declined, together with the rate of transpiration, throughout the afternoon as δea increased despite increasing leaf water potentials. The concentration of CO2 inside leaves (ci) increased as stomatal conductance declined indicating increasing non-stomatal limitations to photosynthesis. The stomatal response to δel of E. globulus in the field is best described as an ‘apparent feed-forward response’ that probably results from both slowly reversible depression of net photosynthesis and abscisic acid accumulation in guard cells. We suggest that the stomatal response to ci may strengthen the link between photosynthetic capacity and stomatal conductance during leaf drying as a result of either drought or large δ el.

    Stable expression of meningococcal class 1 protein in an antigenically reactive form in outer membranes of Escherichia coli (1990)

    Notes: The entire gene encoding the class 1 outer membrane protein of Neisseria meningitidis is located on a 2.2 kb fragment, obtained on digestion of chromosomal DNA with Xbal. This Xbal fragment from strain MC50 (subtype P1-16), which had previously been cloned in bacteriophage M13, has been transferred to the plasmid vector pMTL20. The resulting plasmid (pPORA100) was propagated in Escherichia coli (JM109) and cell lysates were subjected to SDS-PAGE. Western blotting with anti-class 1 protein antibodies revealed constitutive expression of a protein of 41kD, corresponding to the class 1 protein of the parent meningococcal strain, which was absent in the E. coli control Fractionation of E. coli cells carrying the recombinant plasmid revealed that the protein was exclusively located in the outer membrane, and N-terminal amino acid analysis of the expressed protein revealed that normal processing of the signal peptide had occurred. Immuno-gold electron microscopy showed that the protective epitope recognized by a P1-16 subtype-specific monoclonal antibody was exposed in an antigenically reactive form on the surface of E. coli cells carrying plasmid pPORA100. In contrast, expression in E. coli of a second plasmid (pPORA104) lacking the coding sequence for the first 15 amino acids of the signal peptide resulted in accumulation of recombinant class 1 protein only in the cytoplasm of the cells.Thus the presence of the meningococcal signal sequence ensures expression of this meningococcal porin protein in an antigenically native conformation in outer membranes of E. coli, while its absence results in expression of a soluble protein. Such constructs illustrate the potential use of recombinant DNA technology for the development of effective human vaccines against meningococcal infection.
