Regulation of Typical Hypoxia OMCL Families Despite High Oxygen Conditions.
(A) The homologs of the Arabidopsis core hypoxia gene set that were differentially regulated upon submergence. For most Arabidopsis genes, several homologous OMCL families were found (Eval < 1.0E-10). R.a. = Rumex acetosa; R.p. = Rumex palustris.
(B) Oxygen content in the Rumex petioles upon complete submergence under light conditions (mean ± sem, n = 3). Representative traces for both species are given, where the shaded areas mark measurements inside the petioles.
