Some Gracilaria species are difficult to identify morphologically and molecular phylogenetic data hold a key role in species level identification. In this study, the chloroplast genomes of G. changii and G. salicornia from the Peninsular Malaysia were sequenced to compare with the published taxa in order to gain a better understanding of the phylogenetic questions regarding the red algae, particularly G. changii and G. firma. Phylogenetic analysis for 66 plastid genes showed that G. changii from Malaysia formed a sister lineage with G. firma with a genetic distance of 0.43 %. However, there was a genetic distance of p = 4.32 % between the Malaysian and Philippine samples of G. changii, indicating they are genetically distinct. Five chloroplast genes (petF, rps12, rps14, rpl18 and petB) showed higher variation of genetic distance between Malaysian G. changii and G. firma (p = 1.23–2.00 %) and the intraspecific variation in G. salicornia from Peninsular Malaysia and Hawaii varies from p = 0–0.31 %. The lack of overlap between the intraspecific genetic distance of Malaysian G. changii and interspecific genetic distance of Malaysian G. changii-G. firma indicates that G. changii and G. firma are not conspecific.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42203356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed two newly collected Erythrotrichia isolates using rbcL DNA sequences and determined their species status using four DNA-based species delimitation methods. One isolate (KNU-1) grouped with E. carnea in three methods: Assemble Species by Automatic Partitioning, both single-threshold and multiple-threshold general mixed yule coalescent, but grouped as a distinct species in the statistical parsimony network analysis. A second isolate (KNU-2) was considered a distinct species in all the above species-delimitation methods. We propose the name, Erythrotrichia johnawestii sp. nov., for this new species. The new species was different from E. carnea in lacking a thick outer cell wall layer and with a smaller cell size. Mature monosporangia produced raised openings that released monospores. Cell walls were not detected in newly released monospores but began to appear when the spore attached to the substratum and produced rhizoids. Sexual reproduction was not observed during the four-year culture period.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45815897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Halymenia samples were collected from nine locations along the coast of Viet Nam (8°–17°N) in the South China Sea and Gulf of Thailand. Morphological observations indicated that almost all samples were Halymenia malaysiana which was supported by two genetic markers, rbcL and COI-5P. However, the presence of Halymenia dilatata in Viet Nam is still unresolved. Based on rbcL, the common haplotype in Viet Nam was R1 as in Malaysia and three new haplotypes were added to H. malaysiana for Southeast Asia. Genetic differences were evident between the Sunda Shelf (Viet Nam and Malaysia) populations and those in Philippine waters. We suggest that a combination of morphology and molecular data would be useful to accurately assess the species diversity and phylogeography of Halymenia in Viet Nam and Southeast Asia region.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47037071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying their physiology under stressful conditions is essential in the context of climate change. We characterized two morphotypes with measurements of length, thickness and width of the thallus of the macroalga Fucus guiryi in two localities (north and south) in Tenerife (Canary Islands), the southern limit of distribution of the species. We hypothesized that the individuals from the north locality, especially the large morphotype, would be more vulnerable to desiccation and high temperatures than those from the south. Tolerance to desiccation was tested through two long desiccation experiments and by comparing the vegetative and reproductive blades. Tolerance to high temperatures was tested by keeping the individuals in seawater (26–32 °C) for 24 h. The recovery of physiological functions after the stressful conditions was estimated through maximal photochemical efficiency of PSII. Results indicate that both of the two morphometrically differentiated morphotypes were tolerant to prolonged desiccation; however, the small one was more affected, particularly in the northern locality. The reproductive blades were hardly affected, indicating greater tolerance to desiccation than the vegetative blades. Fucus guiryi showed tolerance to high temperatures (32 °C) suggesting plasticity to future warming scenarios.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44036002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species of Corollospora were identified by ascospore morphology and confirmed through a phylogenetic analysis of the 28S rDNA with other published sequences. The phylogenetic analysis revealed four previously unknown clades of Corollospora spp. related to C. portsaidica, while differences in ascospore morphology of the isolates in these four clades were observed. A total of 13 species of arenicolous marine fungi was identified from the 11 sandy beaches, including two Arenariomyces spp., nine Corollospora spp. (including four unknown Corollospora clades), Kohlmeyeriella crassa and Carbosphaerella cf sp. Taan Beach had the highest species richness (eight species), followed by Yongzhen Sea Park and Pisirian (five species each). The Shannon’s diversity index revealed the highest diversity at Taan Beach (1.51) over Pisirian (1.44), but the diversity was more even at the latter site (Pielou’s evenness index = 0.9) compared with the former (0.73). Non-metric multidimensional scaling suggests that there was generally a divide in the fungal community composition between the east and the west coasts of Taiwan.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47908789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
