string: …transgenic lines harbouring 4 9 SARE after 24 h p.i. with Pto, and OFP fluorescence decreased in transgenic lines containing 4 9 PR1 after 24 h p.i. with Pto (Liu et al., 2013a); field evaluations yielded significantly induced OFP fluorescence only at or after 48 h postphytobacterial treatments.
