Summary: This review discusses the phytotoxic essential oils (EOs) and their chemical compositions reported from 1972 to 2020, highlighting the importance of oxygenated terpenes, mono- and sesquiterpenes in the phytotoxicity of EOs. Monoterpenes such as pinene, 1,8 cineole, linalool, and carvacrol, as well as sesquiterpenes like caryophyllene and its derivatives, are identified as key components in the phytotoxicity of EOs. Further studies are recommended to evaluate the pure form activities, determine field application, assess safety, and understand modes of action for these compounds.

Summary: The study identified a potential role of the R2R3-MYB transcription factor HcMYB132 in regulating floral aroma synthesis in Hedychium coronarium. The expression of HcMYB132 correlates with the emission of floral volatile compounds, suggesting its involvement in terpenoid biosynthesis. Silencing of HcMYB132 led to reduced levels of floral volatile compounds and downregulation of key structural volatile synthesis genes, indicating its significant regulatory role in terpenoid biosynthesis in H. coronarium.

Summary: The aim of this study is to experimentally determine the daily evapotranspiration (ET) of the invasive species H. coronarium and compare it with a group of four native species. Three different treatments were carried out in a greenhouse, indicating that different species use water differently. The maximum accumulated daily ET occurred in the mixture treatment, while the treatment with the invasive plant had the lowest value. H. coronarium can reduce evapotranspiration in invaded areas and increase it when immersed in the riparian forest.

Summary: Cryptomeria japonica biomass was obtained monthly from forest lumbering operations in Sao Miguel, Terceira, and Pico (Azores) between May 2018 and June 2020. The chemical composition of the essential oil samples showed distinct clusters, with one cluster grouping samples extracted from branches, foliage, and strobili, while another cluster grouped samples isolated from wood. Despite variations in some diterpenes, the study confirmed the homogeneity of Cryptomeria japonica essential oil obtained from plant material collected in the Azores islands, aiming to add value to the product obtained from forest lumbering.
