Nitric oxide and the control of firefly flashing.
Bioluminescent flashing is essential for firefly reproduction, yet the specific molecular mechanisms that control light production are not well understood. We report that light production by fireflies can be stimulated by nitric oxide (NO) gas in the presence of oxygen and that NO scavengers block bioluminescence induced by the neurotransmitter octopamine. NO synthase is robustly expressed in t...
متن کاملLight-responsive organic flashing electron ratchet.
Ratchets are nonequilibrium devices that produce directional motion of particles from nondirectional forces without using a bias, and are responsible for many types of biological transport, which occur with high yield despite strongly damped and noisy environments. Ratchets operate by breaking time-reversal and spatial symmetries in the direction of transport through application of a time-depen...
متن کاملThe effect of bicarbonate on photosynthetic oxygen evolution in flashing light in chloroplast fragments.
The ability of bicarbonate ion (HCO(3) (-)) to stimulate photosynthetic oxygen evolution in maize chloroplast fragments exposed to continuous light depends on light intensity. Stimulation by HCO(3) (-) is less at low intensities. In HCO(3) (-)-depleted chloroplasts exposed to brief saturating light flashes, period 4 oscillations (in O(2) yield per flash) are damped within three cycles. Readditi...
متن کاملGrowth Rate of Chlorella in Flashing Light.
An apparatus is described for precise measurement of growth rate of an alga as a function of intensity and intermittency of illumination. Dilution of a culture is controlled by a photometric device to just such a rate as will maintain constant density of population and balance the growth rate. Maintenance of constant volume by an automatic siphon allows direct application of the differential fo...
متن کاملThe Spectral Distribution of Firefly Light. II
The in vivo peak emission wavelengths of bioluminescence are reported for 15 species of American fireflies. A spectrophotometric study of the dorsal light organs of 155 specimens of the Jamaican firefly Pyrophorus plagiophthalamus showed three distinct color distributions with peak emission wavelengths at 550.1 +/- 1.5 mmicro, 556.8 +/- 1.4 mmicro, and 562.4 +/- 1.0 mmicro. Similar spectral mea...
