Entrainment of Lemna CO(2) Output Through Phytochrome.

The entrainability of Lemna perpusilla CO(2) output by periodic 15 minute red (R) and far red (F) illuminations was tested in low nitrate medium. R every 8 hour, symbolized R/R/R, gives a flat output (no entrainment) as does F/F/F. However, R/-/- (R every 24 hour) entrains rapidly, and F/-/- does so as well, in a similar manner. The effects of R/R/- and F/F/- also resemble each other closely. E...

Two 10-bp regions are critical for phytochrome regulation of a Lemna gibba Lhcb gene promoter.

Two small regions of the promoter of an Lhcb gene encoding a light-harvesting chlorophyll a/b protein were identified as essential in conferring phytochrome responsiveness by using a transient expression assay. Initially, 5' deletion analysis of cabAB19, an Lhcb2 gene of Lemna, showed that sequences within the region from -174 to -104 relative to the start of transcription were necessary for ph...

Selective Mass Transport of CO2 Containing Mixtures through Zeolite Membranes

In this work, the main aspects regarding the permeation of mixtures containing CO2 and permanent gases such as H2 , N2 and CH4 through zeolite membranes have been investigated, focusing on the description of the mass transport mechanisms taking place inside the pores. First, a brief overview about the performance of the main zeolite membranes used in gas separation (e.g. DDR, CHA, AEI, FAU, etc...

Air entrainment through free-surface cusps.

In many industrial processes, such as pouring a liquid or coating a rotating cylinder, air bubbles are entrapped inside the liquid. We propose that this is due to air being drawn into the narrow channel of a cusp singularity that generically forms on free surfaces. Since the width of the cusp is exponentially small in the driving strength, even the minute viscosity of air is enough to destroy t...

Carbon dioxide output as an index of circadian timing in Lemna photoperiodism.

Previous work on flowering suggested that photoperiodism in Lemna perpusilla 6746 involves an endogenous circadian "clock," but direct evidence requires study of an overt rhythm in the same plant. The CO(2) output rate of axenic cultures supplied with sucrose has been studied in a system using infrared analysis and monitoring four sets of cultures at once. Alternations of (1/4) to 21 hours of d...
