A variety of stimuli, such as abscisic acid (ABA), reactive oxygen species (ROS), and elicitors of plant defense reactions, have been shown to induce stomatal closure. Our study addresses commonalities in the signaling pathways that these stimuli trigger. A recent report showed that both ABA and ROS stimulate an NADPH-dependent, hyperpolarization-activated Ca(2+) influx current in Arabidopsis g...

In this study, the effect of Nauplius Artemia (Nauplii Guard) and adult Artemia (Artemia Guard) in the preservative based on hydro alcoholic extract of Melissa Officinalis and Allium sativum, in order to introduce new Artemia products as aquatic food with domestic production capacity for use in ornamental fish breeding centers. Its effect on the rates of reproductive mortality, reproduction and...

Voltage-gated, Ca2+ release channels have been characterized at the vacuolar membrane of broad bean guard cells using patch clamps of excised, inside-out membrane patches. The most prevalent Ca2+ release channel had a conductance of 27 pS over voltages negative of the reversal potential (Erev) (cytosol referenced to vacuole), with 5,10, or 20 mM Ca2+ as the charge carrier on the vacuolar side a...

Recent reports have shown that GTP-binding proteins (G-proteins) are present in plants but have given limited indication as to their site of action. G-proteins in animal cells transduce extracellular signals into intracellular or membrane-mediated events, including the regulation of ion channels. Using whole-cell patch clamp, we provide evidence that a G-protein in guard cells of fava bean regu...
