Quantitative GUS assay of the AthBTL1 and AthBTL4 promoter lines. The mean values and standard deviations of GUS activity were calculated from three replicates and represented as nanomoles of 4-methyl umbelliferone per milligram protein per minute, as described in Methods. The gray bars represent the expression of the pAthBTL1: GUS and pAthBTL4: GUS fusions harbouring the 5′UTR intron whereas empty bars represent the expression of the intronless promoter: GUS fusions.
