Gene expression analysis of hypoxia-responsive genes (ADH,PCO1,PGB1,LBD41,WIP4,HUP7,HRA1, andPCO2) at ZT4 and ZT20 under long days (LD), and at ZT20 under continuous light (CL) or LD + nocturnal hyperoxia treatment (LD + 50% [O2]). The mRNA levels of genes were measured by RTqPCR, and the data on the y-axis are expressed relative to ZT4 (ZT4 = 1). Statistical significance was calculated using KruskalWallis test followed by post-hoc Wilcoxon test, and groups of significant difference (P< 0.05) are indicated with different letters (n= 6 biological replicates).
