The pvc gene cluster from Pseudomonas aeruginosa has been linked to the biosynthesis of both the pyoverdine chromophore and pseudoverdine. Our reinvestigation of the role this gene cluster plays in P. aeruginosa secondary metabolite biosynthesis shows that its major product is actually paerucumarin, a novel isonitrile functionalized cumarin.

Aquilaria is an evergreen non-timber agarwood obtained from the 15 species of belonging to family Thymelecea. There are two endemic Northeast India, A. malaccensis and khasiana. generate a high-grade degree resin as compared other species, it contributes economy states India country whole. Due its profoundly valuable sources, overexploited, which impacted availability in genetic environments. T...

Streptomyces rapamycinicus strain NRRL 5491 produces the important drug rapamycin. It has a large genome of 12.7 Mb, of which over 3 Mb consists of 48 secondary metabolite biosynthesis clusters.

Aflatoxin B1 (AFB1) is a secondary metabolite produced by some Aspergillus species, which haveharmful impacts on human health such as carcinogenicity, teratogenicity, acute and chronic toxicity.In this study, the occurrence of AFB1 in pistachio nuts during various preparing processes wasinvestigated in two pistachio farms from Qazvin province, Iran, from September to November 2012.High Performa...

The presence of morphine alkaloids, anti-microbial and anti-cancer metabolite, sanguinarine, in different species of Papaver genus has made it one of the most valuable plants in the pharmaceutical industry.With regard to the influence of drought and salinity on the increase of secondary metabolites, the present study attempted to investigate the effect of the mentioned stresses on the key genes...
