    Transgenic Brassica napus plants overexpressing aluminium-induced mitochondrial manganese superoxide dismutase cDNA are resistant to aluminium (2001)
    Oxford, UK : Blackwell Science Ltd
    Plant, cell & environment 24 (2001), S. 0 
    Details
    ISSN: 1365-3040

    Topics: Biology
    Notes: We investigated the role that manganese superoxide dismutase (MnSOD, EC 1·15·1·1), an important enzyme of the antioxidant pathway, may play in aluminium (Al) toxicity/resistance. A wheat (Triticum aestivum) cDNA (WMnSOD) was cloned and up-regulation of the transcript was observed in root tips after 24 h exposure to 100 µm Al. The WMnSOD1 under the control of the CaMV35S promoter was expressed in canola (Brassica napus). Transgenic plants were phenotypically normal. Northern analyses showed enhanced levels of the WMnSOD1 and WMnSOD1-GUS transcripts and total SOD activity was 1·5- to 2·5-fold greater in transgenic plants than in wild type (WT) plants. Transgenic (T1) leaf discs showed increased retention of chlorophyll and reduced electrolyte leakage when exposed to methyl viologen (MV) as compared with WT leaf discs, suggesting that transgenic plants were more resistant to oxidative stress. When WT canola plants were exposed to aluminium (0–200 µm), inhibition of root growth, higher SOD activity and increased levels of malondialdehyde (MDA, an indicator of lipid peroxidation) were observed in roots. Aluminium-induced inhibition of root growth and accumulation of MDA was lower in homozygous transgenic plants (T2) compared with WT plants. Transgenic lines also showed lower synthesis of 1,3-β-glucans (callose, a sensitive marker for Al injury) as compared with WT. These data suggest that resistance to Al toxicity can be improved by overexpressing WMnSOD1.

    Emplacement of xenolith nodules in the Kaupulehu lava flow, Hualalai Volcano, Hawaii (1995)

    Notes: Abstract The basaltic Kaupulehu 1800–1801 lava flow of Hualalai Volcano, Hawaii contains abundant ultramafix xenoliths. Many of these xenoliths occur as bedded layers of semi-rounded nodules, each thinly coated with a veneer (typically 1 mm thick) of lava. The nodule beds are analogous to cobble deposits of fluvial sedimentary systems. Although several mechanisms have been proposed for the formation of the nodule beds, it was found that, at more than one locality, the nodule beds are overbank levee deposits. The geological occurrence of the nodules, certain diagnostic aspects of the flow morphology and consideration of the inferred emplacement process indicate that the Kaupulehu flow had an exceptionally low viscosity on eruption and that the flow of the lava stream was extremely rapid, with flow velocities of at least 10 m s-1 (more than 40 km h-1). This flow is the youngest on Hualalai Volcano and future eruptions of a similar type would pose considerable hazard to life as well as property.

    Notes: Abstract  The basaltic Kaupulehu 1800–1801 lava flow of Hualalai Volcano, Hawaii contains abundant ultramafic xenoliths. Many of these xenoliths occur as bedded layers of semi-rounded nodules, each thinly coated with a veneer (typically 1 mm thick) of lava. The nodule beds are analogous to cobble deposits of fluvial sedimentary systems. Although several mechanisms have been proposed for the formation of the nodule beds, it was found that, at more than one locality, the nodule beds are overbank levee deposits. The geological occurrence of the nodules, certain diagnostic aspects of the flow morphology and consideration of the inferred emplacement process indicate that the Kaupulehu flow had an exceptionally low viscosity on eruption and that the flow of the lava stream was extremely rapid, with flow velocities of at least 10 m s–1 (more than 40 km h–1). This flow is the youngest on Hualalai Volcano and future eruptions of a similar type would pose considerable hazard to life as well as property.

    Quantifying the effect of rheology on lava-flow margins using fractal geometry (1994)
    Springer
    Bulletin of volcanology 56 (1994), S. 193-206

    ISSN: 1432-0819
    Keywords: Key words: Fractals ; lava ; rheology ; remote sensing
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract. This study aims at quantifying the effect of rheology on plan-view shapes of lava flows using fractal geometry. Plan-view shapes of lava flows are important because they reflect the processes governing flow emplacement and may provide insight into lava-flow rheology and dynamics. In our earlier investigation (Bruno et al. 1992), we reported that flow margins of basalts are fractal, having a characteristic shape regardless of scale. We also found we could use fractal dimension (D, a parameter which quantifies flow-margin convolution) to distinguish between the two endmember types of basalts: a′a (D: 1.05–1.09) and pahoehoe (D: 1.13–1.23). In this work, we confirm those earlier results for basalts based on a larger database and over a wider range of scale (0.125 m–2.4 km). Additionally, we analyze ten silicic flows (SiO2: 52–74%) over a similar scale range (10 m–4.5 km). We note that silicic flows tend to exhibit scale-dependent, or non-fractal, behavior. We attribute this breakdown of fractal behavior at increased silica contents to the suppression of small-scale features in the flow margin, due to the higher viscosities and yield strengths of silicic flows. These results suggest we can use the fractal properties of flow margins as a remote-sensing tool to distinguish flow types. Our evaluation of the nonlinear aspects of flow dynamics indicates a tendency toward fractal behavior for basaltic lavas whose flow is controlled by internal fluid dynamic processes. For silicic flows, or basaltic flows whose flow is controlled by steep slopes, our evaluation indicates non-fractal behavior, consistent with our observations.

    The efficiency of copper use by 5A/5RL wheat-rye translocation lines and wheat (Triticum aestivum L.) cultivars (1996)

    Notes: Abstract A greenhouse study was conducted to determine the Cu-efficiency of 5A/5RL wheat-rye translocation lines and nine wheat genotypes grown in a Cu-deficient orthic dark grey chernozemic soil. The soil used was characterized by pH 5.4 and 0.48 μg Cu g−1 soil (DTPA), and was obtained from a known Cu-deficient site at Stony Plain, Central Alberta. Twelve genotypes (three 5A/5RL wheat-rye translocation lines and nine wheat cultivars) and two Cu treatments (soil amended with 145 μg Cu kg−1 soil, and non-amended) were used. The efficiency for Cu use was evaluated for grain yield and yield components. 5A/5RL wheat-rye translocation lines individually and as a group showed significantly (p〈0.05) higher grain yield both in +Cu and −Cu treatments compared to wheat genotypes without the wheat-rye chromosome translocation. 5A/5RL wheat-rye translocation lines demonstrated Cu-efficiency ranging from 70–127% for grain yield. Only two wheat cultivars (Kenya Leopard and Columbus) showed comparable efficiency (70 and 76% respectively). Wheat cultivars Kwale, Kenya Tausi, Roblin, Katepwa, Park, Oslo and Biggar showed low Cu-efficiency (10–36%). The study confirms that the 5A/5RL wheat-rye translocation confers useful levels of Cu-efficiency to wheat, that can be used as an additional source of variability in breeding programs. ei]L V Kochian
