“…NO can control the growth of microalgae by affecting the activity of enzymes (Lehner et al 2009), and its effects depend on the local concentration of NO (Leshem et al 1998;Zhang et al 2005Zhang et al , 2006b; Lehner et al 2009;Tang et al 2011;Misra et al 2014). NO also contributes to protection under abiotic and biotic toxicity stress including copper ion, sodium selenium, lead nitrate, methomyl, and ultraviolet (UV) radiation stress in marine algae (Mackerness et al 2001;Mittler et al 2004;Chen et al 2003;Singh et al 2004;Liu et al 2008;Feng et al 2011;Xiao et al 2012;Li et al 2013;Misra et al 2014). Exogenous NO increases the rate of photosynthesis of Phaeodactylum tricornutum to protect the structure of the cell from high light damage (Wang et al 2013b).…”

Nitric oxide (NO) is a non-traditional regulator of the growth of plants and phytoplankton. Here, the growth of five marine phytoplankton species, Platymonas helgolandica var. tsingtaoensis, Platymonas subcordiformis, Skeletonema costatum, Gymnodinium sp., and Prorocentrum donghaiense, was monitored, and carbonate system parameters in the culture media were determined after adding different concentrations of NO and sodium nitroprusside (SNP, NO donor) solutions. The two dietary algae (P. helgolandica var. tsingtaoensis and P. subcordiformis) and three red tide algae (S. costatum, Gymnodinium sp., and P. donghaiense) showed different responses to the same NO concentration. The red tide algae were more sensitive to exogenous NO than the dietary algae. NO with a concentration of 1.4 × 10 −6 mol L −1 had the optimal stimulatory effect on the growth of the microalgae and increased the cell density by 9.8-38.3%. SNP solution with a concentration of 100 μmol L −1 inhibited the growth of the two dietary algae, and the cell density decreased by 38.8-84.3%. The addition of 10 μmol L −1 SNP solution to the three red tide algae decreased the cell density by 95.3-99.9%. Low concentrations of SNP (0.1 μmol L −1 for the two dietary algae and 0.01 μmol L −1 for the red tide algae) slightly promoted the growth of microalgae. High concentrations of NO (100 μmol L −1 SNP) inhibited CO 2 assimilation, whereas low concentrations of NO (0.01-1.0 μmol L −1 SNP) promoted CO 2 assimilation, indicating that NO participates in the regulation of photosynthesis.
