Summary: This study provides detailed sequencing and comparative analysis of mitochondrial genomes in the green macroalgal genus Ulva, revealing novel findings regarding shared core genes, tRNA evolution, and introns in the genome. Furthermore, phylogenomic analysis confirms the division of Ulva into two lineages. This research is significant for a better understanding of the evolution of mitochondrial genomes in green algae.

Summary: This study sequenced and compared three complete chloroplast genomes of Ulva compressa, revealing that variations in Ulva cpDNA size are mainly caused by intron differences, foreign DNA integration, and non-coding regions. Specific intron types were detected at various insertion sites in Ulva chloroplast genomes, showing a high level of plasticity in their structure due to rearrangement events. Additionally, a degenerate group II intron was found in all Ulva species but not in related taxa, suggesting an independent invasion event in their common ancestor.

Summary: The mtDNA variation among Lactuca species is minimal, with L. serriola showing significant differences from other species, suggesting it may be the direct ancestor of cultivated lettuce. Additionally, a close phylogenetic relationship between the mtDNA of L. sativa and L. virosa was found, indicating a hybridization event between L. virosa and the ancestor of cultivated lettuce led to the mitochondrial genome of L. sativa.

Summary: Comparative analysis of Ulva species' mitogenomes reveals variations in genome size due to the integration of exogenous DNA fragments, proliferation of introns, and changes in repeat sequences. This study focuses on Ulva meridionalis and compares its mitogenomes with those of other ulvophyceae species. Results show that the main circular mitogenomes of U. meridionalis range from 82.94 to 111.49 kb, with the 111.49-kb mitogenome being the largest among Ulva so far. The expansion of U. meridionalis mitogenomes is primarily due to the integration of a 5.36-kb mitochondrial circular plasmid (pUme) and the proliferation of introns. The integration of plasmids and the rapid divergence of plasmid-derived sequences are important evolutionary forces shaping the diversity of Ulva mitogenomes.

Summary: In this study, the chloroplast genomes of Ulva species were sequenced and analyzed. The evolution of Ulva plastomes showed a strong selection pressure for compact genome organization and decreased GC composition. Plastome sequences, including genes, introns, and non-coding regions, exhibited a simultaneous decrease in GC content. The invasion of foreign DNA sequences played an important role in plastome rearrangement. These findings provide new insights into the evolution of plastomes in ecologically important Ulva seaweeds.

Summary: This study assessed different perspectives to establish a stable taxonomic framework for Ulva green seaweed, finding that species delimitation methods using the tufA gene were the most consistent. DNA-based species delimitation often disagreed with traditional morphology-based definitions, and biological species concepts were generally narrower than DNA-based delimitation. Although molecular markers improved our understanding of Ulva diversity, names associated with DNA sequences in public databases are unreliable, highlighting the need for further research in tropical regions.

Summary: Marine green macroalgae, particularly Ulva species, have potential applications in therapeutics due to their bioactive phytochemicals, but are currently under-exploited. Ulva lactuca, a widely grown macroalgae along the Mediterranean coast, is a good source of proteins and nutrients, making it suitable for salad and kimchi preparations. This review highlights the chemistry, structure, and food and pharmaceutical applications of bioactives in green seaweeds and Ulva spp., with the aim of exploiting their nutraceutical properties and pharmaceutical applications.

Summary: The mechanisms involved in anthracene degradation in the marine alga Ulva lactuca were analyzed using transcriptomic analysis. At least three pathways for anthracene and linear hydrocarbons degradation were identified, with multiple enzymes potentially participating in each pathway. Gas chromatography and mass spectrometry confirmed the production of anthracene metabolites, validating one of the identified pathways.

Summary: Tooth decay is a common chronic infection caused by acids produced from bacterial breakdown of sugar in the mouth. In this study, nanocellulose and Ulva/Ag/cellulose/nanocomposites were synthesized using Ulva lactuca as a cellulose source and reducing agent. The tests showed that Ulva/Ag/cellulose/nanocomposites had strong antibacterial activity against S. mutans and L. acidophilus, and they were more effective than materials blended with fluoride.

Summary: Ulva prolifera is a typical macroalga known for forming green tides and causing the largest macroalgal blooms in the Yellow Sea of China. Two gamma-carbonic anhydrase genes were cloned from this species, showing different transcriptional responses to environmental factors, with one gene having increased transcription under low pH conditions and both genes being inhibited under high pH conditions. These findings contribute to our understanding of transcriptional regulation of gamma-CA genes in U. prolifera in response to environmental factors.

Summary: The complete mitochondrial genome of Thalassiosira nordenskioeldii isolated from the East China Sea has been constructed in this study, providing genome data for this ecologically important species. Phylogenetic analysis showed that T. nordenskioeldii's mtDNA is closely related to that of Thalassiosira profunda. The high collinearity between T. nordenskioeldii, T. profunda, and Skeletonema marinoi mtDNAs suggests only minor rearrangements, facilitating evolutionary studies within the order Thalassiosirales and the class Mediophyceae.
