Plant genetic transformation is a pivotal and essential step in modifying important agronomic traits using biotechnological tools, which primarily depend on the efficacy of transgene delivery and the plant regeneration system. Over the years, advancements in the development of delivery methods and regeneration systems have contributed to plant engineering and molecular breeding. Recent studies have demonstrated that the efficiency of plant transformation can be improved by simultaneously delivering meristem-developmental regulators, utilizing virus-mediated gene editing, and executing non-sterile in planta manipulations.

Introduction: Extracts from the rhizome of the traditional Chinese medicinal plant (CY) mediate a number of biologic effects that are associated with its content of isoquinoline alkaloids. CY alkaloids have shown analgesic, cardioprotective, and anti-addictive effects in animal models of disease. Since CY alkaloids are available to consumers as dietary supplements we analyzed the content of alkaloids in 14 products including open powders, capsules, and liquid formulations, capturing a majority of the products available online in the US.

Background: Cannabis sativa L. (Cannabaceae) has been widely used by humans throughout its history for a variety of purposes (medicinal, alimentary and other uses). Armenia, with its rich cultural history and diverse ecosystems, offers a unique context for ethnobotanical research about traditional uses of Cannabis.

Crown rot caused by Fusarium proliferatum is a severe postharvest disease of banana fruit. The N-methyladenosine (mA) modification is the most common type of RNA modification and regulates gene expression in eukaryotes. Here, we analyzed transcriptome-wide changes in mA methylation to investigate post-transcriptional regulation mechanisms of growth and fumonisin biosynthesis of F.

A structurally novel metabolite, fatuamide A (), was discovered from a laboratory cultured strain of the marine cyanobacterium sp., collected from Faga'itua Bay, American Samoa. A bioassay-guided approach using NCI-H460 human lung cancer cells directed the isolation of fatuamide A, which was obtained from the most cytotoxic fraction.
