A Demonstration of DNA Barcoding-Based Identification of Blade-Form Ulva (Ulvophyceae, Chlorophyta) Species from Three Site in the San Juan Islands, Washington, USA

Diversity, 2022
Marine macroalgae are foundation species that play a critical ecological role in coastal communities as primary producers. The macroalgal genus Ulva is vital in intertidal communities, serving as a food source and shelter for organisms, but these species

Salinity and host drive Ulva‐associated bacterial communities across the Atlantic–Baltic Sea gradient

Molecular Ecology, 2022
The green seaweed Ulva is a model system to study seaweed–bacteria interactions, but the impact of environmental drivers on the dynamics of these interactions is little understood.

A novel quantitative analysis for diurnal dynamics of Ulva prolifera patch in the Yellow Sea from Geostationary Ocean Color Imager observation

Frontiers in Marine Science, 2023
IntroductionIn the last decade, the outbreak of large-scale green tides caused by Ulva prolifera has continuously occurred in the Yellow Sea. Satellite remote sensing techniques have been widely used to monitor the distribution area and duration of green

Tandem integration of circular plasmid contributes significantly to the expanded mitochondrial genomes of the green-tide forming alga Ulva meridionalis (Ulvophyceae, Chlorophyta)

Frontiers in Plant Science, 2022
Comparative mitogenomics of Ulva species have revealed remarkable variations in genome size due to the integration of exogenous DNA fragments, the proliferation of group I/II introns, and the change of repeat sequences.

Seasonal variation in productivity, chemical composition and nutrient uptake of Ulva spp. (Chlorophyta) strains

Journal of Applied Phycology, 2022
Applications of seaweeds require the supply of uniform biomass, yet performance of Ulva is generally characterised by a wide variation across study sites and seasons, as well as among species or strains.

Oxidative stress and enzymatic scavenging of superoxide radicals induced by solar UV-B radiation in Ulva canopies from southern Spain

Scientia Marina, 2003
The generation of reactive oxygen species (ROS) and scavenging of the superoxide radical by superoxide dismutase (SOD) was studied in mat-like canopies of the green macroalga Ulva rotundata Bliding in a tidal brine pond system in southern Spain ...

Strong Endemism of bloom-forming tubular Ulva in Indian West Coast, with description of Ulva paschima Sp. Nov. (Ulvales, Chlorophyta). [PDF]

PLoS ONE, 2014
Ulva intestinalis and Ulva compressa are two bloom-forming morphologically-cryptic species of green seaweeds widely accepted as cosmopolitan in distribution. Previous studies have shown that these are two distinct species that exhibit great morphological

Understanding the Evolution of Mitochondrial Genomes in the Green Macroalgal Genus Ulva (Ulvophyceae, Chlorophyta)

Frontiers in Marine Science, 2022
To gain more insights into the evolution of mitochondrial genomes (mitogenomes or mtDNAs) in the green macroalgal genus Ulva (Ulvophyceae, Chlorophyta), we sequenced seven Ulva mitogenomes from six species as well as one Percursaria mitogenome as ...
