Analysis of plant and environmental samples for the quarantine fungus Phyllosticta citricarpa in four European citrus‐growing areas

open access: yesAnnals of Applied Biology, EarlyView.
Methodologies for the early detection of Phyllosticta citricarpa in air and rainwater samples were developed and applied over three consecutive years (2018–2021) in four European citrus sites, previously reported to harbour the pathogen. Phyllosticta citricarpa was not detected in plant, air, or rainwater samples, and no CBS symptoms were observed on ...

Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

open access: yesPlant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

Ontogenia de los estróbilos, desarrollo de los esporangios y esporogénesis de Equisetum giganteum (Equisetaceae) en los Andes de Colombia

open access: yesRevista de Biología Tropical, 2011
Estudios sobre la ontogenia del estróbilo, los esporangios y la biología reproductiva de Equisetum son escasos, por lo tanto, para la especie E. giganteum, se estudiaron estos aspectos en especímenes recolectados a orillas del Río Frío, Santander ...

Carbon and nitrogen contents depends on macroalgal species, their tissue section, and development stage

open access: yesPhycological Research, EarlyView.
SUMMARY Assessing the potential for macroalgae to function as a carbon sink (blue carbon) and nitrogen (N) assimilation is under intensive investigation. The content of elemental carbon (C) and N in macroalgae is the best indicator of their potential; however, with respect to the thallus, C and N content varies in space and time.

Problems in Cladistic Classification: Higher-Level Relationships in Land Plants [PDF]

open access: yes, 1996
Recent cladistic analyses of green plants recognize an extensive hierarchical series of relatively well-supported monophyletic groups. Translating this hierarchical pattern of relationships into a usable and informative written classification is ...

Effects of temperature on sexual competition in three kelp species, Pterygophora californica, Nereocystis luetkeana, and Macrocystis pyrifera: Implications for range shifts in foundation species

open access: yesPhycological Research, EarlyView.
SUMMARY Kelp forests are threatened by rising ocean temperatures. However, the effects of warming on early life stage interactions among co‐occurring kelp species, particularly competitive dynamics and reproductive timing, remain poorly understood. This study investigates the effects of temperature on embryonic sporophyte competitive interactions and ...

Evolutionary history of the Corallinales (Corallinophycidae, Rhodophyta) inferred from nuclear, plastidial and mitochondrial genomes [PDF]

open access: yes, 2011
Systematics of the red algal order Corallinales has a long and convoluted history. In the present study, molecular approaches were used to assess the phylogenetic relationships based on the analyses of two datasets: a large dataset of SSU sequences ...

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

open access: yesNew Phytologist, Volume 250, Issue 1, Page 629-647, April 2026.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.
