Nitric Oxide in Cytokinin and Polyamine Signaling: Similarities and Potential Crosstalk,al examples the biosynthesis of NO is up-regulated sorapidly that a function of NO as a second messenger in signal transduction seems likely. We investigatedthis postulate with the signal substances cytokinin and polyamines. After polyamine addition to . seedlings, net NO biosynthesis increased with

Nitric Oxide and Plant Ion Channel Control,iological studies of guard cells, there is good reasonto expect similar patterns of action in other plant cell types as well. As in animals, NO appears to actthrough two distinct mechanisms. One mechanism is mediated via stimulation of guanylate cyclase, whichleads to a rise in cyclic ADP-ribose and

Fluorometric Detection of Nitric Oxide with Diaminofluoresceins (DAFs): Applications and Limitationificance, however, the unique challenges of NO research can bring confusion to investigations, primarily due to difficulties in detecting and quantifying biological NO production. To overcome such barriers, we recommend that researchers choose a combinatorial approach for monitoring NO levels, in wh
