Polyamines Induce Rapid Biosynthesis of Nitric Oxide (NO) in Arabidopsis thaliana Seedlings

Factors regulating ethylene biosynthesis in etiolated Arabidopsis thaliana seedlings

while the other interactions tested were essentially additive. We examined the effect on etiolated Arabidopsis thaliana seedlings of a wide variety of factors that are known to induce Auxin and cytokinin have been shown to act synergistically to elevate ethylene biosynthesis in many other plant tissues. We ethylene in other plant tissues. Auxin, cytokinin, brassinosteroid and cupric ion were fo...

Carotenoid Biosynthesis in Seed of Arabidopsis thaliana

Nitric Oxide Biosynthesis

The nature of the membrane currents mediating agonist-induced Ca'+ entry and enhanced nitric oxide (NO) production in endothelial cells is still unclear. Using both perforated-patch and conventional whole-cell clamp technique, we have studied the membrane response associated with histamine stimulation of human vascular endothelial cells. In perforated-patch experiments, the initial histamine (1...

Hydrogen peroxide acts upstream of nitric oxide in the heat shock pathway in Arabidopsis seedlings.

We previously reported that nitric oxide (NO) functions as a signal in thermotolerance. To illustrate its relationship with hydrogen peroxide (H₂O₂) in the tolerance of Arabidopsis (Arabidopsis thaliana) to heat shock (HS), we investigated the effects of heat on Arabidopsis seedlings of the following types: the wild type; three NADPH oxidase-defective mutants that exhibit reduced endogenous H₂O...
