Overall changes of gene expression levels in different Klebsormidium species and Zygnema circumcarinatum. Left (greenish) bars: number of up-regulated transcripts. Right (reddish) bars: number of down-regulated transcripts. The Klebsormidium experiments were performed at either 5 °C or 20 °C (data from Holzinger et al., 2014; Rippin et al., 2019a). For Z. circumcarinatum, the type of cultivation (L, liquid culture, 1 month old; P2 agar plate culture, 7 months old) is indicated (data from Rippin et al., 2017). The temperature in the Z. circumcarinatum experiment was 20 °C.
