DNAH8 and nutritional disorder: Nevertheless, a bHLH transcription factor FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR (EgFIT) was significantly upregulated at 11 d.p.i rather than 3 and 7 d.p.i. It is an integral regulator in response to iron deficiency which upon activation will trigger downstream iron uptake genes, like ferric reduction oxidase 2 (FRO2) and ATPase AHA2 [39].
