“…Also, it helps in determining the authenticity of a bioactive containing plant. The known plant secretory structures are trichome, idioblast, secretory cavities, secretory canal, laticifer, and osmophores (Kuster and Vale 2016;Naidoo and Naidoo 2018;De Godoy et al, 2019;Almeida et al, 2020). Studies related to the distribution of secretory structures and the histochemical analysis of Curculigo species (Hypoxidaceae) are still limited.…”

Curculigo orchioides and Curculigo latifolia (Hypoxidaceae) have been widely used as traditional medicines in Indonesia and other Asian countries for antihyperglycemic, aphrodisiac, antioxidant, and antimicrobial treatments. This work aimed to determine the distribution of secretory structures and metabolites. Metabolite profiling approach of the plant organs was determined by UHPLC-Q-Orbitrap-HRMS. Histochemical-based techniques on rhizome, root, petiole, and leaf, with transversal sections on fresh samples, were prepared using a razor blade to determine the secretory structures of the plants, followed by plant anatomy procedures. Histochemical analysis was carried out using several reagents to detect the metabolites. Metabolite profiling revealed several classes of compounds, i.e. phenolics, alkaloids, terpenes, essential oils, and lipophilic. Secretory cavities and idioblast cells, were detected in both species and localize a diverse metabolites. Additionally to the specialized structures, hypodermis, epidermis, intercellular spaces, and cuticle also contain some of those compounds. The secretory structures spread over the different organs. This discovery may be useful to distinguish particular organs as medicine source, which does not only depend on the availability of rhizome. The secretory structures and the chemical compounds of the two species, described herein for the first time, can be used further in plant identification purposes based on chemical markers.

Portulaca hatschbachii is endemic to the basaltic rocky outcrops that are distributed, in a discontinuous way, along the Third Plateau of Paraná State, Brazil, composing environments that form the Subtropical Highland Grasslands of the Atlantic Forest Biome. Considering the risk of extinction of the species and the massive anthropization of these outcrops, we applied AFLP, ITS and rps16 molecular markers in ten populations throughout the area of occurrence of the species to generate information about the genetic status of P. hatschbachii and contribute to the development of conservation strategies. Low rates of genetic diversity, high population structure, restricted gene flow and the presence of diversifying selection were observed for the populations. The analysis of variation partitioning (R2adj. = 63.60%) showed that environmental variables have a greater influence on the distribution of variation of loci under selection (R2adj. = 26.70%) than geographical isolation (R2adj. = 1.20%). The strong population structure, for both neutral and selected loci, suggests an isolation by adaptation mechanism (IBA) occurring in populations and highlights the need and urgency for in situ conservation plans for the species and its occurrence on rocky outcrops.
