RCO-3 and COL-26 form an external-to-internal module that regulates the dual-affinity glucose transport system in

摘要

COL-26 is a key transcription factor that regulates the dual-affinity glucose transport system in N. crassa. a Relative expression level of glt-1 in 36 transcription factor mutants of N. crassa grown in Vogel’s minimal medium (VMM) supplemented with glucose as the sole carbon source. Detailed information about these transcription factors is shown in Additional file 1: Table S1. b Relative expression of glt-1 and hgt-1/-2 in the presence of glucose and in carbon-free conditions in the wild-type (WT) strain and Δcol-26 mutant. c Subcellular location of COL-26 in N. crassa exposed to a gradient of glucose.
