Specific Binding of the Syringolide Elicitors to a Soluble Protein Fraction from Soybean Leaves.
Syringolides are glycolipid elicitors produced by Gram-negative bacteria expressing Pseudomonas syringae avirulence gene D. The syringolides mediate gene-for-gene complementarity, inducing the hypersensitive response only in soybean plants carrying the Rpg4 disease resistance gene. A site(s) for 125I-syringolide 1 was detected in the soluble protein fraction from soybean leaves, but no evidence...
متن کاملCharacterization of a 34-kDa soybean binding protein for the syringolide elicitors.
Syringolides are water-soluble, low-molecular-weight elicitors that trigger defense responses in soybean cultivars carrying the Rpg4 disease-resistance gene but not in rpg4 cultivars. 125I-syringolide 1 previously was shown to bind to a soluble protein(s) in extracts from soybean leaves. A 34-kDa protein that accounted for 125I-syringolide 1 binding activity was isolated with a syringolide affi...
متن کاملCry1Ac, a bacillus thuringiensis toxin, triggers extracellular Ca2+ influx and Ca2+ release from intracellular stores in Cf1 cells
Intracellular Ca2+ concentration was measured in single Cf1 cells (Choristoneura fumiferana, spruce budworm) loaded with Fura-2, a Ca2+-sensitive fluorescent probe. Cf1 cells displayed Ca2+ surges in response to Cry1Ac and Cry1C proteins, two Cf1-toxic Bacillus thuringiensis products, but not to Cry1Aa and Cry3A, which are not toxic to Cf1 cells. In the presence of extracellular Ca2+, the toxin...

adrenal cortex and brown adipose tissue: Crompton et al., 1978; Nicholls, 1978; Al-Shaikhaly et al., 1979), the fluxes of Ca2+, Na+ and H+ may be integrated into a cycle (Fig. l), for which evidence has been published (Crompton el al., 1976; Crompton & Heid, 1978; Nicholls & Scott, 1980). In cardiac muscle the cycle would never reach steady state, as it does in vitro, since the [Caz+] in the cy...
متن کاملA balancing act: efflux/influx in mycobacterial drug resistance.
Since the discovery of the tubercle bacillus by Robert Koch in 1882 (110), a greater understanding of the dynamics and survival mechanisms of this pathogen has led to more questions than answers. Despite stringent control strategies and many advances in our knowledge of the epidemiology of tuberculosis (TB) and the biology of the causative agent Mycobacterium tuberculosis, TB still remains one ...
