1. Promoting Butenyl-spinosyn Production Based on Omics Research and Metabolic Network Construction in Saccharopolyspora pogona
Zirong Zhu,Ziyuan Xia,Duo Jin,Shengbiao Hu,Yunjun Sun,Ziquan Yu,Yang Liu,Qingji Xie,Liqiu Xia,Ling Shuai,Jie Rang,Li Cao J Agric Food Chem . 2022 Mar 23;70(11):3557-3567. doi: 10.1021/acs.jafc.2c00285.
Understanding the metabolism ofSaccharopolyspora pogonaon a global scale is essential for manipulating its metabolic capabilities to improve butenyl-spinosyn biosynthesis. Here, we combined multiomics analysis to parseS. pogonagenomic information, construct a metabolic network, and mine important functional genes that affect the butenyl-spinosyn biosynthesis. This research not only elucidated the relationship between butenyl-spinosyn biosynthesis and the primary metabolic pathway but also showed that the low expression level and continuous downregulation of thebuscluster and the competitive utilization of acetyl-CoA were the main reasons for reduced butenyl-spinosyn production. Our framework identified 148 genes related to butenyl-spinosyn biosynthesis that were significantly differentially expressed, confirming that butenyl-spinosyn polyketide synthase (PKS) and succinic semialdehyde dehydrogenase (GabD) play an important role in regulating butenyl-spinosyn biosynthesis. Combined modification of these genes increased overall butenyl-spinosyn production by 6.38-fold to 154.1 ± 10.98 mg/L. Our results provide an important strategy for further promoting the butenyl-spinosyn titer.
2. Duplication of partial spinosyn biosynthetic gene cluster in Saccharopolyspora spinosa enhances spinosyn production
Xuezhi Ding,Yuanwei Jiang,Yushuang Luo,Liqiu Xia,Fan Huang,Ying Tang FEMS Microbiol Lett . 2011 Dec;325(1):22-9. doi: 10.1111/j.1574-6968.2011.02405.x.
Spinosyns, the secondary metabolites produced by Saccharopolyspora spinosa, are the active ingredients in a family of insect control agents. Most of the S. spinosa genes involved in spinosyn biosynthesis are found in a contiguous c. 74-kb cluster. To increase the spinosyn production through overexpression of their biosynthetic genes, part of its gene cluster (c. 18 kb) participating in the conversion of the cyclized polyketide to spinosyn was obtained by direct cloning via Red/ET recombination rather than by constructing and screening the genomic library. The resultant plasmid pUCAmT-spn was introduced into S. spinosa CCTCC M206084 from Escherichia coli S17-1 by conjugal transfer. The subsequent single-crossover homologous recombination caused a duplication of the partial gene cluster. Integration of this plasmid enhanced production of spinosyns with a total of 388 (± 25.0) mg L(-1) for spinosyns A and D in the exconjugant S. spinosa trans1 compared with 100 (± 7.7) mg L(-1) in the parental strain. Quantitative real time polymerase chain reaction analysis of three selected genes (spnH, spnI, and spnK) confirmed the positive effect of the overexpression of these genes on the spinosyn production. This study provides a simple avenue for enhancing spinosyn production. The strategies could also be used to improve the yield of other secondary metabolites.
3. Conversion of spinosyn A and spinosyn D to their respective 9- and 17-pseudoaglycones and their aglycones
H A Kirst,J W Paschal,L C Creemer J Antibiot (Tokyo) . 1998 Aug;51(8):795-800. doi: 10.7164/antibiotics.51.795.
Forosamine at the 17-position of spinosyns A and D was hydrolyzed under mild acidic conditions to give the corresponding 17-pseudoaglycones. The tri-O-methylrhamnose at the 9-position of the 17-pseudoaglycone of spinosyn A was hydrolyzed under more vigorous acidic conditions to give the aglycone of spinosyn A. However, these conditions led to decomposition of the 17-pseudoaglycone of spinosyn D, presumably due to more facile protonation of the 5,6-double bond to produce a tertiary carbonium ion which undergoes further rearrangements. Spinosyns J and L (3'-O-demethyl spinosyn A and D, respectively) obtained from fermentation of biosynthetically-blocked mutant strains of Saccharopolyspora spinosa, were oxidized to give the corresponding 3'-keto-derivatives and the resultant keto-sugars were then beta-eliminated under basic conditions to give the 9-pseudoaglycones of spinosyns A and D respectively. Forosamine at the 17-position of the 9-pseudoaglycone of spinosyn D was then readily hydrolyzed to yield the aglycone of spinosyn D.
4. Insecticide resistance in the Cydia pomonella (L): Global status, mechanisms, and research directions
Xiao-Qi Wang,Ya-Lin Zhang,Xue-Qing Yang,Di Ju,David Mota-Sanchez,Eduardo Fuentes-Contreras Pestic Biochem Physiol . 2021 Oct;178:104925. doi: 10.1016/j.pestbp.2021.104925.
The codling moth, Cydia pomonella (Lepidoptera: Tortricidae) is a major pest of pome fruit and walnuts worldwide. Although environmentally compatible integrated control strategies, such as mating disruption, attract-kill strategy, and sterile insect technique have been conducted for management of this notorious pest, effects to control of codling moth have mainly relied on insecticides. In consequence, different levels of insecticide resistance towards organophosphates, neonicotinoids, hydrazines, benzoylureas, pyrethroids, diamides, spinosyns, avermectins, JH mimics, carbamates, oxadiazines and C. pomonella granulovirus (CpGVs) have developed in codling moth in different countries and areas. Both metabolic and target-site mechanisms conferring resistance have been revealed in the codling moth. In this review, we summarize the current global status of insecticide resistance, the biochemical and molecular mechanisms involved, and the implications for resistance management.
