Fig. 6From: Extra-large G proteins regulate disease resistance by directly coupling to immune receptors in Nicotiana benthamianaNbxlg3,5 mutant plants have enhanced resistance to abiotic stresses. a Nbxlg3,5 mutant plants showed significantly enhanced resistance to salt and osmotic stresses. Nicotiana benthamiana seedlings were vertically grown on 1/2 MS medium supplemented with different concentrations of NaCl, mannitol, or PEG for 7 days. The seedlings were photographed and root length was measured. The related statistical data was shown in Additional file 1: Figure S8. b Nbxlg4 mutant plants showed normal resistance to salt and osmotic stresses. N. benthamiana seedlings were vertically grown on 1/2 MS medium supplemented with different concentrations of NaCl, mannitol, or PEG for 7 days. The seedlings were photographed and root length was measured. The related statistical data was shown in Additional file 1: Figure S9Back to article page
