Stachyose treatment induced TUNEL positive nuclei in N. benthamiana. TUNEL Assays were done on sugar treated Nicotiana benthamiana triplicate biological replicates to detect apoptotic-like cell death. N. benthamiana samples treated with DNAse were used as positive controls as DNAse induces nuclei fragmentation. (a) 5 U/μl DNase treated samples (positive control); (b) 3.2 mg/ml Stachyose treated samples; (c) No enzyme control (Negative control); (d) 5 mM Trehalose treated samples (48 h). Arrows represent DNA fragmentation.
