P. agglomerans 33.1::pNKGFP density during sugarcane cross-colonization,
measured using qPCR (A) and reisolation (B) at 4 and 15 DAI. The
abundance data, in CFU/g of tissue, were log transformed to stabilize the variance.
The results are the means of the four replicates for each sample. The bars
represent the standard error of each treatment.
