The 44th volume of RAP contains articles based on work presented at the 51st annual meeting of the Phytochemical Society of North America. They were selected to showcase exciting examples of current research in plant chemistry, to highlight the diversity in this field spanning analytical chemistry, ethnobotany, biosynthesis, bioactivity, chemical ecology and biotechnology. Specifically, the perspectives paper by Zerbe and Bohlmann summarizes recent findings on the genes and enzymes involved in conifer resin biosynthesis, while papers by Timoshenko et al. and Guerrero-Analco et al. highlight progress on toxic lectins and bioactive phytochemicals from Canadian forest plants used by Aboriginals, respectively. Next the contribution by Glover and Murch compares methods used to analyze dementia agents in foodstuffs of Pacific Islands. Two papers by Lisko et al and Berhow et al. both summarize recent findings on the engineering of vitamin C contents of plants and of phytochemicals in the emerging oil crop Camelina. Finally, Cook et al discuss the biosynthesis in plant endophytes of alkaloids which have implications for cattle feeding. Overall, these seven Perspectives and Communications give a very good picture of the state of plant (bio) chemistry research in North America, which is also indicative of the state of the field worldwide.

This text provides both review and primary research articles for a broad audience of biologists, chemists, biochemists, pharmacologists, clinicians and nutrition experts, especially those interested in the biosynthesis, structure, function and/or bioactivity of plant natural products. Recurring themes include the evolution and ecology of specialized metabolites, the genetic and enzymatic mechanisms for their formation and metabolism, the systems biology study of their cell/tissue/organ context, the engineering of plant natural products, as well as various aspects of their application for human health. In addition to analysis of current research, new developments in the techniques used to study plant natural products are presented and discussed, taking a detailed look at structure elucidation and quantification, "omic" (genomic/ proteomic/ transcriptomic/ metabolomics) profiling or for microscopic localization. In short, this series combines chapters from researchers that explain and discuss current topics in the most exciting new research in phytochemistry.
