“…Some algae such as the oceanic phytoplankton, the seaweeds along almost every coastline in the world, or the algae of lakes and riversseem abundant, giving the general impression of commonness for the entire group (Brodie et al 2009). However, many algae are restricted in their distribution and vulnerable due to rising levels of adverse stressors, including climate change, colonisation by alien species, eutrophication, and increases in harmful phytoplankton species (Satta et al 2017). A recent paper on Sardinian charophytes (Becker 2019), defined as 'terra incognita', demonstrated that nine of the 26 taxa known in Sardinia are very rare and endangered.…”

“…Several temporary wet habitats with populations of rare taxa are threatened by invasive plant species such as Cyperus eragrostis or Campylopus introflexus (Cogoni et al 2009;Mayoral et al 2018). Other coastal and inland wetland types are also severely altered and threatened by other invasive alien plant species such as Hydrocotyle ranunculoides, Cortaderia selloana, and Eichornia crassipes or by increasing blooming events of Chattonella subsalsa (Brundu et al 2013;Satta et al 2017;Mayoral et al 2018). To date, there has not been any extensive overview of wetland plants in Sardinia.…”

Where we Come from and where to Go: Six Decades of Botanical Studies in the Mediterranean Wetlands, with Sardinia (Italy) as a Case Study

Plants are key elements of wetlands due to their evolutionary strategies for coping with life in a water-saturated environment, providing the basis for supporting nearly all wetland biota and habitat structure for other taxonomic groups. Sardinia, the second largest island of the Mediterranean Basin, hosts a great variety of wetlands, of which 16 are included in eight Ramsar sites. The 119 hydro- and hygrophilous vascular plant taxa from Sardinia represent the 42.6% and 37.9% of the number estimated for Italy and Europe, respectively. Moreover, around 30% of Sardinia’s bryological flora, which is made up of 498 taxa, is present in temporary ponds. An overview at regional scale considering algae is not available, to our knowledge, even though several specific studies have contributed to their knowledge. In order to find the most investigated research themes and wetland types, identify knowledge gaps and suggest recommendations for further research, we present a first attempt to outline the work that has been hitherto done on plants in lentic habitats in Sardinia. Three plant groups (algae, bryophytes and vascular plants), and five research themes (conservation, ecology, inventory, palaeobotany and taxonomy) were considered. After a literature review, we retained 202 papers published from 1960 to 2019. We found that studies on vascular plants, as plant group, were disproportionately more numerous, and inventories and ecology were the most investigated research themes. Although efforts have recently been made to fill these long-lasting gaps, there is a need for updating the existing information through innovative methods and integrative approaches.

“…In temperate and subtropical-tropical regions of the world, the fish-killing (ichthyotoxic) raphidophytes Chattonella species have frequently caused serious damage to fisheries and mariculture industries in Korea (Kim et al 2007), Japan (Imai andYamaguchi 2012, Yamaguchi et al 2018), China (Wang et al 2006(Wang et al , 2017, North America (Lewitus et al 2008, García-Mendoza et al 2018, and Europe (Stacca et al 2016, Satta et al 2017, Zingone et al 2020. The production of superoxide is associated with the growth of Chattonella, which is a strong candidate for the cause of its toxicity in fishes (Shikata et al 2019).…”

“…In Japan, the genus Chattonella , including C. antiqua , C. marina , and C. ovata , has caused the most harm to the aquaculture industry (Imai and Yamaguchi, 2012). Chattonella subsalsa forms red tides in the United States and Europe (Zhang et al, 2006; Satta et al, 2017) but not in Japan.…”

RNA-Seq Analysis Reveals Genes Related to Photoreception, Nutrient Uptake, and Toxicity in a Noxious Red-Tide Raphidophyte Chattonella antiqua

et al. 2019

Aquaculture industries are under threat from noxious red tides, but harm can be mitigated by precautions such as early harvesting and restricting fish feeding to just before the outbreak of a red tide. Therefore, accurate techniques for forecasting red-tide outbreaks are strongly needed. Omics analyses have the potential to expand our understanding of the eco-physiology of these organisms at the molecular level, and to facilitate identification of molecular markers for forecasting their population dynamics and occurrence of damages to fisheries. Red tides of marine raphidophytes, especially Chattonella species, often extensively harm aquaculture industries in regions with a temperate climate around the world. A red tide of Chattonella tends to develop just after an input of nutrients along the coast. Chattonella displays diurnal vertical migration regulated by a weak blue light, so it photosynthesizes in the surface layer during the daytime and takes up nutrients in the bottom layer during the nighttime. Superoxide produced by Chattonella cells is a strong candidate for the cause of its toxicity to bacteria and fishes. Here we conducted mRNA-seq of Chattonella antiqua to identify genes with functions closely related to the dynamics of the noxious red tide, such as photosynthesis, photoreception, nutrient uptake, and superoxide production. The genes related to photosynthetic pigment biosynthesis and nutrient uptake had high similarity with those of model organisms of plants and algae and other red-tide microalgae. We identified orthologous genes of photoreceptors such as aureochrome (newly five genes), the cryptochrome/photolyase (CRY/PHR) family (6-4PHR, plant CRY or cyclobutane pyrimidine dimer [CPD] Class III, CPD Class II, and CRY-DASH), and phytochrome (four genes), which regulate various physiological processes such as flagellar motion and cell cycle in model organisms. Six orthologous genes of NADPH oxidase, which produces superoxide on the cell membrane, were found and divided into two types: one with 5–6 transmembrane domains and another with 11 transmembrane domains. The present study should open the way for analyzing the eco-physiological features of marine raphidophytes at the molecular level.
