    Alteration of stimulus-specific guard cell calcium oscillations and stomatal closing in Arabidopsis det3 mutant (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-09-29
    Description: Cytosolic calcium oscillations control signaling in animal cells, whereas in plants their importance remains largely unknown. In wild-type Arabidopsis guard cells abscisic acid, oxidative stress, cold, and external calcium elicited cytosolic calcium oscillations of differing amplitudes and frequencies and induced stomatal closure. In guard cells of the V-ATPase mutant det3, external calcium and oxidative stress elicited prolonged calcium increases, which did not oscillate, and stomatal closure was abolished. Conversely, cold and abscisic acid elicited calcium oscillations in det3, and stomatal closure occurred normally. Moreover, in det3 guard cells, experimentally imposing external calcium-induced oscillations rescued stomatal closure. These data provide genetic evidence that stimulus-specific calcium oscillations are necessary for stomatal closure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, G J -- Chu, S P -- Schumacher, K -- Shimazaki, C T -- Vafeados, D -- Kemper, A -- Hawke, S D -- Tallman, G -- Tsien, R Y -- Harper, J F -- Chory, J -- Schroeder, J I -- R01 GM60396-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 29;289(5488):2338-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell and Developmental Biology Section, Division of Biology and Center for Molecular Genetics, University of California, San Diego, La Jolla, CA 92093-0116, USA. gallen@biomail.ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11009417" target="_blank"〉PubMed〈/a〉

    A calcium-dependent protein kinase with a regulatory domain similar to calmodulin (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-17
    Description: Calcium can function as a second messenger through stimulation of calcium-dependent protein kinases. A protein kinase that requires calcium but not calmodulin or phospholipids for activity has been purified from soybean. The kinase itself binds calcium with high affinity. A complementary DNA clone for this kinase has been identified; it encodes a protein with a predicted molecular mass of 57,175 daltons. This protein contains a catalytic domain similar to that of calmodulin-dependent kinases and a calmodulin-like region with four calcium binding domains (EF hands). The predicted structure of this kinase explains its direct regulation via calcium binding and establishes it as a prototype for a new family of calcium-regulated protein kinases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harper, J F -- Sussman, M R -- Schaller, G E -- Putnam-Evans, C -- Charbonneau, H -- Harmon, A C -- GM15731/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 May 17;252(5008):951-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany, Louisiana State University, Baton Rouge 70803.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1852075" target="_blank"〉PubMed〈/a〉

    Notes: In 1986 the author's previous paper describing a simple mathematical model for the forces driving the plates had an rms error of 1.62 per cent in its best case. The model included slab pull and its global and local reactions proportional to speed times (age)3/2, viscous drag due to shear under moving plates and in the flow towards mantle sinks at midocean ridges and sources at subduction zones, ridge push proportional to plate age, and friction at continental collision zones. Strengths of the various forces were found by least-squares fitting. Three different improvements now reduce the error to 1.14 per cent. They are (1) revision of the N–S American plate boundary east of the Caribbean sea to run along the 15°20′ fracture zone, (ii) removal of a transform segment from the Caribbean subduction zone, and (iii) allowing for ‘hotspot push’. Hotspots cause upward flow in the mantle, which spreads outwards under the lithosphere above, and pushes two plates apart if their boundary runs nearby, in a way which is calculated.The results and their statistical significance are estimated by a method given by Backus, Park & Garbasz (1981), modified slightly because three of the equations in the model are linearly dependent on the remainder. All the physical mechanisms envisaged in this work as driving plates turn out to be significant except local reaction to slab pull, the effect of which is very small anyway.

    Cell specific expression of three genes involved in plasma membrane sucrose transport in developingVicia faba seed (1997)
    Springer

    Keywords: Gene expression ; Plasma membrane transport ; Seed ; Sucrose efflux/influx ; Transfer cells ; Vicia faba

    Topics: Biology
    Notes: Summary In developing seeds ofVicia faba, transfer cells line the inner surface of the seed coat and the juxtaposed epidermal surface of the cotyledons. Circumstantial evidence, derived from anatomical and physiological studies, indicates that these cells are the likely sites of sucrose efflux to, and influx from, the seed apoplasm, respectively. In this study, expression of an H+/sucrose symporter-gene was found to be localised to the epidermal-transfer cell complexes of the cotyledons. The sucrose binding protein (SBP) gene was expressed in these cells as well as in the thin-walled parenchyma transfer cells of the seed coat. SBP was immunolocalised exclusively to the plasma membranes located in the wall ingrowth regions of the transfer cells. In addition, a plasma membrane H+-ATPase was most abundant in the wall ingrowth regions with decreasing levels of expression at increasing distance from the transfer cell layers. The observed co-localisation of high densities of a plasma membrane H+-ATPase and sucrose transport proteins to the wall ingrowths of the seed coat and cotyledon transfer cells provides strong evidence that these regions are the principal sites of facilitated membrane transport of sucrose to and from the seed apoplasm.

    Surface activity and bubble motion (1982)

    Notes: Abstract This paper reviews recent progress in the theories of the surface boundary conditions of adsorbed solutes in liquids, and of the effects of those solutes on the steady motion of a bubble or drop in the liquid. Both singular perturbation theory and numerical solutions have useful roles in this problem, and their relationship is explored. In addition, analytical solutions are given to two problems concerning a spherical bubble rising steadily at low Reynolds number in a viscous fluid. One of these is displacement of the internal vortex centre from its position in the absence of surface activity when there is a small stagnant cap of surfactant at the rear. The results agree with experimental data in the direction of that displacement but give only about half its amount. The other problem is the velocity perturbation all round the surface caused by a very dilute solution of a weak surfactant at high Péclet number. This compares quite well with the numerical solution for a Péclet number of 60, having relative errors of order (60)−1/2 as would be expected.

    Adhesion enhancement of rubbery and ductile polyolefin coatings on glass fibers for epoxy composites and effects on failure mechanism (1993)

    Notes: Dilute polyolefin solutions, respectively based on EPDM and UHMWPE, were reacted with functionalized silanes to prepare coatings for glass fibers. These were found to provide adequate bonding characteristics for both glass and epoxy resin (bisphenol type). Unidirectional composites containing fiber matrix interlayers, using fibers coated with the aforementioned functionalized polyolefins, were found to exhibit much larger tanδ values over the temperature range of 60 to +60°C and greater ductility in flexural tests, albeit at the expense of a reduction in failure stresses. The UHMWPE coatings produced a multiple step fracture mechanism, which was deemed to provide a more efficient crack stopping mechanism than equivalent EPDM coated fibers. © 1993 John Wiley & Sons, Inc.
