Figure Lengend Snippet: In vivo G FP expression analysis control of the native and mutated promoters of AmXLN2 , AmBXL2 and AmABF1 . ( a ) Schematic representation of the native promoters and their variants with deleted putative XlnR-binding sites: P XLN2 Δ:P XLN2 with 5′-GGCTGA-3′ deleted; P BXL2 Δ:P BXL2 with 5′-GGTTAA-3′ deleted; P ABF1 Δ:P ABF1 with 5′-GGCTAT-3′ deleted. ( b ) Relative fluorescence intensity, ( c ) relative GFP transcriptional level, and ( d ) bright-field and corresponding fluorescence images of the reporter strains. Three independent replicates were performed for the statistical analysis. ∗ P < 0.05,∗∗ P < 0.01, ns: no significance.

Article Snippet: GFP fluorescence intensity was visualized using an Olympus U-LH100HG fluorescent microscope and quantified using a BioTeK Synergy H1 Hybrid Reader (BioTek Instruments Inc., USA) (485 nm excitation and 520 nm emission).
