Abstract
Nitric oxide NO is an important signal molecule in stress responses Accumulation of secondary metabolites often occurs in plants subjected to stresses including various elicitors or signal molecules NO has been reported to play important roles in elicitorinduced secondary metabolite production in tissue and cell cultures of medicinal plants Better understanding of NO role in the biosynthesis of such metabolites is very important for optimizing the commercial production of those pharmaceutically significant secondary metabolites This paper summarizes progress made on several aspects of NO signal leading to the production of plant secondary metabolites including various abiotic and biotic elicitors that induce NO production elicitortriggered NO generation cascades the impact of NO on growth development and programmed cell death in medicinal plants and NOmediated regulation of the biosynthetic pathways of such metabolites Crosstalks among NO signaling and reactive oxygen species salicylic acid and jasmonic acid are discussed Some perspectives on the application of NO donors for induction of the secondary metabolite accumulation in plant cultures are also presentedThis work was supported by grants from Soochow Scholar Program No 14317363 the National Natural Science Foundation of China 30772731 the fifth Jiangsu Leading Discipline Program BU 132802 and the projectsponsored by PAPD and SRF for ROCS K513201011
