Comparative genome-wide characterization leading to simple sequence repeat marker development for Nicotiana

BMC Genomics, 2018
Background Simple sequence repeats (SSRs) are tandem repeats of DNA that have been used to develop robust genetic markers. These molecular markers are powerful tools for basic and applied studies such as molecular breeding.

Plant-Based Vaccine Production Through Transient Expression System: A Narrative Review

Life and Science
Transient expression systems involve the temporary expression of a foreign gene in plant tissues to enable efficient, high-yield vaccine production. Plant-based systems minimize contamination risks because the introduced gene does not integrate into the ...

DNA methylation valley as a distinguishing feature occurs in root-specific expressed nicotine-related genes in Nicotiana attenuata

Frontiers in Plant Science
IntroductionNicotine, the main defense alkaloid of Nicotiana species, is synthesized exclusively in the roots. Several studies have shown that changes in DNA methylation patterns are associated with altered expression of genes involved in the ...

Generation of the Camptothecin Scaffold by a Flavin‐Catalyzed Photooxidative Skeletal Reorganization

Angewandte Chemie, EarlyView.
The biosynthetic pathway of the anticancer drug precursor camptothecin involves an enigmatic skeletal reorganization from a 6/5/6 tetrahydro‐β‐carboline to a 6/6/5 pyrroloquinoline ring system. Here, we show that this transformation can be achieved by photooxidation with flavin cofactors, such as flavin mononucleotide (FMN) as catalysts.
