The auxin-synthesizing activity of endophytic fungi from desert halophyte plants Aeluropus litoralis, Halocnemum strobilaceum, Climacoptera crassa, Suaeda heterophylla were studied. In addition, screening of indole-3-acetic acid (IAA) was carried out at the cultivation of endophytes in the presence of 10% NaCl. All isolates produced IAA, but the highest level was observed in two Penicillium strains from C. crassa and H. strobilaceum, which produced significant amounts of extracellular IAA at a relatively low biomass level.
