Microorganisms and growth conditions. Pantoea agglomerans 33.1, isolated
from Eucalyptus grandis plants (58), and its derivative tagged strain,
33.1::pNKGFP (25), as well as Escherichia coli derivatives were routinely
grown at 28°C and 37°C, respectively, on Luria-Bertani (LB) medium
(67). The tagged strain 33.1::pNKBOR was obtained according to the
methodology described by Ferreira et al. (25). All of the strains (Table 1)
were stored in 20% glycerol at80°C. The plasmids were propagated and
isolated from E. coli DH5 pir or Top10 and purified with a plasmid
miniprep kit (Mobio) according to the manufacturer’s recommendations.
