From: Genomic analysis reveals the major driving forces of bacterial life in the rhizosphere
Microarray profiling of bacterial gene expression in the rhizosphere. (a-c) Global gene expression of P. putida KT2440 was analyzed in the rhizosphere versus that of LB log bacteria (OD660 = 0.7) (a, a'), LB stationary phase cells (OD660 = 3.3) (b, b'), and sessile bacterial cells incubated in sand microcosms (c, c'). Experimental set up and cDNA preparation are described in detail in Materials and methods. Genes induced (red) and repressed (green), with a P value < 0.05 and A >64 were clustered according to their fold change (>2 to >10) and (≤2 to ≤10) and the number is plotted.
