TLC analysis obtained with 14C labeled N-acetylglucosamine of Nod factors produced by R. gallicum bv. gallicum R602T and R. leucaenae CFN 299T grown under saline stress. Bacteria were induced (+) or not (−) with a flavonoid nod-gene inducer (apigenin, 3.7 μM), under different levels of saline stress (concentration of NaCl). Lines 1 and 2 represent the control without saline stress
