Fig. 3From: Ectopically expressing MdPIP1;3, an aquaporin gene, increased fruit size and enhanced drought tolerance of transgenic tomatoesSubcellular localization of MdPIP1;3 on plasma membrane. a Transgenic Arabidopsis protoplasts transiently expressing MdPIP1;3-eGFP fusion protein. b Transgenic Arabidopsis protoplasts transiently expressing eGFP control. They were observed using confocal microscopy with 600 × magnification (objective magnification × eyepiece magnification = 60 × 10).
