    Notes: Abstract Salt-stressed plants often show Ca deficiency symptoms. The effects of NaCl salinity (1 to 150 mol m-3) and supplemental Ca (10 mol m-3) on Na and Ca transport in barley (Hordeum vulgare L.) and their relationship to growth were investigated. The adjustment of Na and Ca transport was investigated by examining young seedlings exposed to short-term (immediate) and long-term (7 d) exposure to salinity. When the plants were exposed to long-term treatments of salinity, the rate of sodium accumulation in roots was approximately 10 to 15% of short-term treatments. No significant adjustment in the transport to the shoot was observed. Rates of tracer (22Na) transport were compared to calculated rates based on relative growth rates and tissue element concentrations. Comparisons between measured tracer and calculated rates of transport indicate that 22Na transport may underestimate transport to the shoot because of dilution of the tracer in the root cytoplasm. Calcium uptake showed only minor adjustment with time. Measured rates of tracer transport to the shoot correlated well with calculated values. The transport and tissue concentrations of Na were significantly affected by supplemental Ca. Calcium transport and tissue concentrations were markedly inhibited by salinity. Supplemental Ca increased Ca transport and accumulation at all NaCl treatments above that of control plants without supplemental Ca. Salinity inhibited plant growth at 150 mol m -3NaCl, but not at 75 mol m-3.Supplemental Ca significantly improved root length but not fresh weight after 7d of salinity, although differences in fresh weight were detected after 9d. There were significant Na-Ca interactions with ion transport, ion accumulation, and growth. The effects of salinity on Na and Ca transport to the shoot do not appear to play a major role in shoot growth of barley.

    Aqueous silicate complexes in wheat, Triticum aestivum L. (2004)

    Notes: The chemical speciation of silicon in xylem exudate from wheat (Triticum aestivum L.) was examined by 29Si NMR spectroscopy. Wheat plants were grown to maturity in silicon-free nutrient medium, and then transferred to a solution containing 0.02 mm29Si-enriched silicic acid. After 30 min the shoots were excised and xylem exudate was collected. Within 10 min the Si concentration of the xylem exudate reached values greatly in excess of that of the starting nutrient solution, eventually reaching levels as high as 8 mm. Silicon-29 nuclear magnetic resonance spectra indicated the existence of only two Si-containing species in the xylem exudate, mono and disilicic acid (H4SiO4o and (HO)3Si(µ-O)Si(OH)3o) in a ratio of approximately 7 : 1. Significantly, there was no evidence of organosilicate complexes. Nevertheless, the efficiency by which the plant concentrates aqueous silicon indicates active mechanisms of silicon transport across root cell membranes.

    An automated greenhouse sand culture system suitable for studies of P nutrition (1990)

    Notes: Abstract. Maintenance of realistically low solution P concentrations under controlled conditions is a major difficulty in studies of P nutrition. In this report, we describe a relatively simple and economical sand culture system capable of sustaining plant growth to maturity under controlled yet realistic P regimes. The system uses Al2O3 as a solid-phase P buffer, and modern process control technology to control irrigation and addition of other mineral nutrients. Aspects of the design, use and potential applications of automated solid-phase systems are discussed. The system was used to grow Phaseolus vulgaris to matarity at 0.4 mmol m3, 1.0 mmol m3 and 27 mmol m3 P with and without mycorrhizal inoculation. At flowering, low solution P concentrations were associated with reduced leaf concentrations of P in nonmycorrhizal plants, and reduced leaf concentrations of Ca in both mycorrhizal and nonmycorrhizal plants. Mycorrhizal inoculation increased leaf P, K, Mg and Mn concentrations, but reduced leaf N concentration. Low P regimes reduced final seed yield by diminishing both the number of pods per plant and the number of seeds per pod. Mycorrhizal inoculation significantly enhanced seed yield under low P regimes by increasing seed weight, the number of pods per plant, and the number of seeds per pod.

    Notes: Abstract Seeds of Lyeopersicon esculentum cv. VF36 (a salt-sensitive cultivar), L. esculentum var. Edkawi (which is fairly salt-resistant), and a wild relative, L. cheesmanii, were exposed to various concentrations of NaCl, up to 460 mol m−3, either directly or following imbibition in non-saline nutrient solution. After 10 d exposure to salt, they were transferred to non-saline solution. All taxa showed some germination at the lowest salinity tested, 92 mol m−3 NaCl, but virtually no germination occurred at 184 mol m−3 NaCl or higher salinities. Within 2 d after removal of the salt stress, however, the seeds of L. esculentum reached control levels of germination, even if they had already been on the verge of germination when the stress was imposed. The seeds of L. cheesmanii were less resistant to NaCl. The physiological basis for the resistance of VF36 seeds is discussed.

    Identification of a novel mutation in keratin 1 in a family with epidermolytic hyperkeratosis (2000)

    Notes: Abstract: Epidermolytic hyperkeratosis (EHK) is a hereditary skin disorder typified by blistering due to cytolysis. One in 100,000 individuals is affected by this autosomal-dominant disease. The onset of the disease phenotype is typically at birth. Histological and ultrastructural examination of the epidermis shows a thickened stratum corneum and tonofilament clumping around the nucleus of suprabasal keratinocytes. Linkage studies localized the disease genes on chromosomes 12q and 17q which contain the type II and type I keratin gene clusters. Recently, several point mutations in the genes encoding the suprabasal keratins, K1 and K10, have been reported in EHK patients. We have investigated a large kindred affected by EHK and identified a new point mutation in the 2B region of keratin 1 (I107T), resulting from a T to C transition in codon 478.
