Fig. 4From: Isolation, purification and characterization of an ascorbate peroxidase from celery and overexpression of the AgAPX1 gene enhanced ascorbate content and drought tolerance in ArabidopsisSubcellular localization analysis of AgAPX1. a Control vector (pA7-GFP) expressed in onion epidermal cells. b Recombinant vector (AgAPX1-GFP) expressed in onion epidermal cells. c AgAPX1-GFP fusion proteins transiently expressed in Arabidopsis mesophyll protoplasts. GFP: green fluorescent protein; BF: bright field; chloroplast: chlorophyll auto fluorescence; merged: combined fluorescence from GFP, BF, and chloroplastBack to article page
