This study aimed to characterize some microalgae by their taxonomy and biochemical composition.

Subsequently, microalgal growth under laboratory conditions was assessed and the microalgal cells were harvested to determine the pigments, proximate composition, fatty acid, and amino acid profiles. The findings indicated that the cell densities of Coccomyxa sp. and Ochromonas sp. were nearly identical. Additionally, all microalgae exhibited chlorophyll a as the main pigment component, whereas Coccomyxa sp. and Chlorococcum sp. showed significantly highest (p < 0.05) chlorophyll a (7.79 ± 0.07 μg · mL<sup>-1</sup>) and chlorophyll b (2.74 ± 0.002 μg · mL<sup>-1</sup>), respectively. Significantly higher (p < 0.05) carotenoid and total phycobiliproteins content were found in Ochromonas sp. Furthermore, Coccomyxa sp. was determined to have significantly higher (p < 0.05) protein (31.9% ± 0.46% dry weight) and lipid content (18.2% ± 1.34% dry weight), while the maximum carbohydrate was detected for Ochromonas sp. (29.2% ± 0.1% dry weight). Lastly, essential amino acid (EAA) levels were considerably higher (p < 0.05) in Chlorococcum sp.; however, Coccomyxa sp. produced more polyunsaturated fatty acids (PUFA) in comparison to the other experimental species.

The PyYEATS protein, mainly localized in nuclei with a small amount in cytosolic fractions in thalli, harbored a classic YEATS domain followed by a coiled-coil domain at the C-terminal. This locus exhibited conservation in domain structure compared with its homologs in other red algae and showed a closer relationship to animal GAS41 counterparts than plant YAFs. In vitro assays showed that the PyYEATS protein preferentially binds H3K14ac, H3K18ac, and H4K5ac and that the F105, W124, and F127 residues in the YEATS domain are essential for its affinity to these histone acetylation sites.

We used whole genome sequencing to determine whether these lineages represente species. Whole genomes of 69 individuals from five genetically distinctive lineages in the Gulf of Alaska (United States) and Salish Sea (Canada) were analyzed, along with 63 genomes from three other species of Alaria. Our analysis of >3.4 million single nucleotide polymorphisms reaffirmed that organellar and nuclear phylogenetic signals are incongruent in Alaria, producing different topologies among five organellar and six nuclear A. marginata lineages. Lineages appeared to be reproductively isolated, as evidenced by strong clustering and lack of recent admixture across nuclear genomes. Genetic divergence between A. marginata lineages also exceeded intra-lineage divergence, proxied by A. esculenta populations, but fell short of distances observed across other species of Alaria. Despite the genomic data supporting predictions of the biological and genetic species concepts, we encountered inherent limitations in declaring species status.

Bacteria influence host health and can facilitate or hinder host survival and acclimation to stressful abiotic conditions. Therefore, understanding how bacterial communities change under abiotic stress is critical for understanding how abiotic stress will affect kelp physiology. We investigated the effect of abiotic stress on Saccharina and associated bacteria by surveying the bacterial community associated with Saccharina across naturally occurring salinity and temperature gradients, coupled with salinity manipulation experiments. Overall, Saccharina harbored a stable core bacterial community, which decreased in relative abundance under abiotic stress. In the field, both salinity and temperature shaped the bacterial community, with temperature having higher explanatory power most of the time. In the lab, we confirmed that the patterns observed in the field could be replicated by manipulating salinity alone.
