Toxicity of essential oils from Nordic plants against different pathogenic organisms and pests of cultivated plants

open access: yesAnnals of Applied Biology, Volume 188, Issue 1, Page 160-169, January 2026.
Plant essential oils (EOs) represent a potentially effective, safe, and eco‐friendly alternative to synthetic pesticides that cause negative effects for human health and the environment. The present study evaluated in airtight glass chambers the toxicity of vapours produced by EOs obtained from sweet gale, balsam poplar, Labrador tea, jack pine, and ...

The Chaetophorales (Chlorophyceae) – a taxonomic revision at family level

open access: yesEuropean journal of phycology, 2018
The Chaetophorales (Chlorophyceae) consist of filamentous green algae that were mostly described directly from natural samples by light microscopy. However, the descriptions were often based on morphological characters that are either homoplasious or ...

Integrated chloroplast genomics and whole‐genome resequencing reveals demographic history and selection signatures of black walnuts

open access: yesThe Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Elucidating the impacts of demographic history and genomic selection on species evolution is a central topic in phylogeography and evolutionary biology. Black walnuts (Juglans section Rhysocaryon) are native nut trees of the NEW WORLD, with a broad distribution ranging from southern Canada to northern Argentina.

Heterogeneity in global vegetation and terrestrial climate change during the late Eocene to early Oligocene transition [PDF]

open access: yes, 2017
Rapid global cooling at the Eocene – Oligocene Transition (EOT), ~33.9–33.5 Ma, is widely considered to mark the onset of the modern icehouse world. A large and rapid drop in atmospheric pCO2 has been proposed as the driving force behind extinctions in ...

Phenolic compounds as chemical markers of low taxonomic levels in the family Poaceae

open access: yes, 2018
The spectra of non-structural phenolics in herbage were used to study genetic affinity in polyploid complex of Dactylis L., next in complex of octoploid brome species, and in red fescue cultivar collection.

Taxonomic and functional diversity of cultured seed associated microbes of the cucurbit family

open access: yesBMC Microbiology, 2016
BackgroundEndophytes are microbes that colonize plant internal tissues without causing disease. In particular, seed-associated endophytes may be vectors for founder microbes that establish the plant microbiome, which may subsequently contribute ...

Woody Host‐Specific Type III Effector HopBL2 Is Essential for Pseudomonas savastanoi Virulence and Associates With Plasmodesmata

open access: yesMolecular Plant Pathology, Volume 26, Issue 9, September 2025.
HopBL2, a T3SS effector specific to woody plant infection, is delivered into plant cells, localises to subcellular structures and is required for Pseudomonas savastanoi virulence in oleander. ABSTRACT The type III secretion system in Pseudomonas syringae complex pathogens delivers type III effectors (T3Es) into plant cells to manipulate host processes,

Unfolding the Complete Chloroplast Genome of Myrica esculenta Buch.‐Ham. ex D.Don (1825): Advancing Phylogenetic Insights Within Fagales and Pioneering DNA Barcodes for Precise Species Identification

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
This study presents the complete chloroplast genome of Myrica esculenta (159,538 bp) and its phylogenetic placement within the Fagales order. Phylogenetic analysis using the ycf1 gene confirmed a monophyletic clade with other Morella species, highlighting ycf1 as a promising DNA barcode for species identification.

A survey of selected coastal vegetation communities of Florida [PDF]

open access: yes, 1977
A survey of coastal vegetation around Florida was conducted during 1973 and 1974. Seventeen sites were selected and sampled using the transect method to determine species occurrence, relative densities, and habitat development and structure.
