O2 exchanges in X. elegans thalli successively incubated in dark and saturating light. Theses traces were obtained with thalli fragments incubated in an oxygen-electrode chamber. Numbers on the traces refer to nmol of O2 consumed or produced min−1 g−1 lichen dry weight. Thalli (th) were introduced in the chamber as dry fragments in dark (A1) or light (A2), or as wet fragments in dark (B1) or light (B2). The incubation medium contained 0.1 mM bicarbonate at pH 6.8. Open arrows, light on; solid arrows, light off.
