The transcriptional response of PabHLH1 to stress. Thallus was treated with SA (a), or exposed to UV radiation (b). The reference sequence used for the qRT-PCR was a gene encoding an elongation factor. The results were shown as the mean of three replicate reactions with standard deviations, *p < 0.05, ** p < 0.01 according to Student’s t-test
