BGL3I impacted on the hydrolysis and uptake of extracellular lactose. a Lactose concentration, b galactosidase activity, c transcription level of galactosidase gene bga1, d transcription level of lactose permease gene 3405, e transcription level of lactose permease gene 77517, f transcription level of lactose permease gene 79202. Lactose permease genes were detected at 4 h, 16 h and 24 h after the induction with 1% lactose in WT and Δbgl3i mutant. Transcripts were normalized to the housekeeping gene actin. Vertical bars indicate SD and each reaction was done in triplicate
