Co-expression of PYE and OLV genes.

Co-expression network of Fe deficiency-responsive genes. OLV belongs to a sub-network of FIT target genes (surrounded by a blue dashed line). FIT is a transcription factor required for up-regulated expression of FIT target genes in response to Fe deficiency in roots of seedlings (Schwarz and Bauer, 2020). PYE belongs to a sub-network of Fe homeostasis genes (surrounded by a red dashed line) up-regulated upon Fe deficiency in roots and shoots of seedlings, also in the absence of FIT (Schwarz and Bauer, 2020). The ATTED-II tool (Ver. 9.2) was used to generate the network (Obayashi et al., 2018) based on PYE and OLV as input genes. The violet arrow links the two genes encoding the interacting proteins PYE and OLV.
