Expression of Nicotiana benthamiana beta-hexosaminidases (HEXOs). GFP- or RFP-tagged HEXOs or IL-22-GFP (used as apoplast control protein) were transiently expressed in N. benthamiana leaves. As a negative control (–) p19 was used. Leaves were harvested 3 days post infiltration and analyzed by western blot. (A) anti-GFP western blot under reducing conditions of 10 μg total soluble protein of apoplast fluids or intracellular fraction upon expression of IL-22-GFP (22), HEXO2A (2A), HEXO2B (2B), or HEXO3B (3B). (B) anti-RFP western blot under reducing conditions of 10 μg total soluble protein of apoplast fluids or intracellular fraction upon expression of HEXO1A (1A) or HEXO3A (3A).
