Rhythmic Variation of SsAQP2 Expression in the Motor Tissues.
Phosphorimager scans of RNA gel blots of total RNA from extensor or flexor parts of secondary pulvini with probes to SsAQP2 and 18S rRNA. Numbers are abbreviations of the time of sampling: day (13:00), evening (19:00), night (01:00), and morning (07:00). D/D, continuous darkness, measurements between 39 and 64 hr after lights went off at the end of a normal day; D/L, diurnal alternations of dark and light; D/L-INV, dark/light illumination inverted (leaves were harvested 7 days after the inversion); E, extensor; F, flexor.
