The development of spaceflight experiments withArabidopsis as a model system in gravitropism studies
Journal of Plant Research - Tập 111 - Trang 463-470 - 1998
Experiments withArabidopsis have been developed for spaceflight studies in the European Space Agency's Blorack module. The Biorack is a multiuser facility that is flown on the United States Space Shuttle and serves as a small laboratory for studying cell and developmental biology in unicells, plants, and small invertebrates. The purpose of our spaceflight research was to investigate the starch-sta......
Physiological functions of plant cell coverings
Journal of Plant Research - Tập 115 - Trang 277-282 - 2002
The cell coverings of plants have two important functions in plant life. Plant cell coverings are deeply involved in the regulation of the life cycle of plants: each stage of the life cycle, such as germination, vegetative growth, reproductive growth, and senescence, is strongly influenced by the nature of the cell coverings. Also, the apoplast, which consists of the cell coverings, is the field w......
Unique after-hyperpolarization accompanying action potential inChara globularis
Journal of Plant Research - Tập 107 - Trang 371-375 - 1994
A unique after-hyperpolarization was found in internodal cells ofChara globularis. The cells generated an ordinary action potential due to regenerative depolarization induced by the outward electric current pulse larger than a threshold stimulus. After reaching a depolarizing peak, the membrane potential repolarized and overshooted the resting potential to a value which was somehow 40 mV more nega......

Involvement of the C-terminal Region in Phosphate Inhibition of Plasma Membrane Proton Pumping Activity

In situ Inactivation of the Oxidase Activity of Xylem Peroxidases by H2O2 in the H2O2-Producing Xylem of Zinnia elegans
Journal of Plant Research - Tập 112 - Trang 383-390 - 1999
stems with 3,3′, 5, 5′-tetramethylbenzidine (TMB) in the presence and in the absence of catalase reveals the presence of xylem oxidase activities in the H2O2-producing lignifying xylem cells. This staining of lignifying xylem cells with TMB is the result of two independent mechanisms: one is the catalase-sensitive (H2O2-dependent) peroxidase-mediated oxidation of TMB, and the other the catalase-i......
Endogenous indole-3-acetic acid and ethylene evolution in tilted Metasequoia glyptostroboides stems in relation to compression-wood formation
Journal of Plant Research - Tập 117 - Trang 171-174 - 2004
Eight-year-old Metasequoia glyptostroboides seedlings were tilted at a 45° angle to induce compression-wood formation on the lower side of the stems. After 2 weeks of treatment, half of the seedlings were sampled and the remaining half were tilted to the opposite orientation to exchange the upper and lower sides and were kept for 2 more weeks until sampled. Cambium-emitted ethylene was analyzed by......
The remarkable genus Coptosapelta (Rubiaceae): pollen and orbicule morphology and systematic implications
Journal of Plant Research - Tập 117 - Trang 57-68 - 2003
The pollen morphology and distribution of orbicules were investigated in ten species of the genus Coptosapelta (Rubiaceae) using light, scanning electron and transmission electron microscopy. In general, Coptosapelta pollen is three- to five-pororate and suboblate to oblate-spheroidal. The sexine ornamentation varies from psilate to reticulate, and the pollen-wall stratification lacks columellae. ......
Induction of hydrotropism in clinorotated seedling roots of Alaska pea,Pisum sativum L.
Journal of Plant Research - Tập 109 - Trang 335-337 - 1996
Roots of the agravitropic pea (Pisum sativum L.) mutantageotropum show positive hydrotropism, whereas roots of Alaska peas are hydrotropically almost non-responsive. When the gravitropic response was nullified by rotation on clinostats, however, roots of Alaska peas showed unequivocal positive hydrotropism in response to a water potential gradlent. These results suggest that roots of Alaska peas p......
