Fig. 4From: Phytohormone up-regulates the biochemical constituent, exopolysaccharide and nitrogen metabolism in paddy-field cyanobacteria exposed to chromium stressImpact of exogenous supplementation of phytohormones (Indole acetic acid; IAA and Kinetin; KN) on glutamine synthetase (a, b), glutamate synthase (c, d) and glutamate dehydrogenase (e, f) activities of Nostoc muscorum and Anabaena sp. exposed to CrVI stress for 96 h. Data are means±standard error of three replicates (n = 3). Bars followed by different letters show significant difference at P < 0.05 according to Duncan multiple range test (DMRT)Back to article page
