Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa. -
Divergence Time Estimates and the Evolution of Major Lineages in The
www.nature.com/scientificreports OPEN Divergence time estimates and the evolution of major lineages in the florideophyte red algae Received: 31 March 2015 Eun Chan Yang1,2, Sung Min Boo3, Debashish Bhattacharya4, Gary W. Saunders5, Accepted: 19 January 2016 Andrew H. Knoll6, Suzanne Fredericq7, Louis Graf8 & Hwan Su Yoon8 Published: 19 February 2016 The Florideophyceae is the most abundant and taxonomically diverse class of red algae (Rhodophyta). However, many aspects of the systematics and divergence times of the group remain unresolved. Using a seven-gene concatenated dataset (nuclear EF2, LSU and SSU rRNAs, mitochondrial cox1, and plastid rbcL, psaA and psbA genes), we generated a robust phylogeny of red algae to provide an evolutionary timeline for florideophyte diversification. Our relaxed molecular clock analysis suggests that the Florideophyceae diverged approximately 943 (817–1,049) million years ago (Ma). The major divergences in this class involved the emergence of Hildenbrandiophycidae [ca. 781 (681–879) Ma], Nemaliophycidae [ca. 661 (597–736) Ma], Corallinophycidae [ca. 579 (543–617) Ma], and the split of Ahnfeltiophycidae and Rhodymeniophycidae [ca. 508 (442–580) Ma]. Within these clades, extant diversity reflects largely Phanerozoic diversification. Divergences within Florideophyceae were accompanied by evolutionary changes in the carposporophyte stage, leading to a successful strategy for maximizing spore production from each fertilization event. Our research provides robust estimates for the divergence times of major lineages within the Florideophyceae. This timeline was used to interpret the emergence of key morphological innovations that characterize these multicellular red algae. The Florideophyceae is the most taxon-rich red algal class, comprising 95% (6,752) of currently described species of Rhodophyta1 and possibly containing many more cryptic taxa2. -

Marine Algal Endophyte and Epiphytes New to New Caledonia
Bull. Natn. Sci. Mus., Tokyo, Ser. B, 24(3), pp. 93-101, September 22, 1998 Marine Algal Endophyte and Epiphytes New to New Caledonia Taiju Kitayama' and Claire Garrigue' 'Department of Botany, National Science Museum, 4-1-1 Amakubo, Tsukuba, Ibaraki, 305-0005 Japan 'ORSTOM, BP A5, Nouméa, New Caledonia Abstract Four microscopic multicellular algae, Plzaeophila deidroides (Chloro- phyceae, Phaeophilales), Feldinannia irregularis, Feldrnaniiizia indica (Phaeo- phyceae, Ectocarpales), Stylonema alsidii (Rhodophyceae, Porphyridiales) were recorded for the first time from the coast of New Caledonia. Plzaeophila deizdroides is an endophyte in Dictyota and the rest are epiphytes on Turbinaria ornata or Sphacelaria rigidula. The three genera and the three orders are new records in New Caledonia. Key words : Algal flora, endophyte, epiphyte, Feldnzannnia indica, Feldmaiznia ii*regularis,New Caledonia, Phaeoplzila dendroides, Phaeophyceae, Rhodophyceae, Stylonema alsidii, Ulvophyceae. Since Kiitzing (1863) published the first records of New Caledonian algae based on E. Vieillard's collections, there have been few further publications focussed on marine benthic algae from New Caledonia including Gepp (1922), Catala (1950), May (1953, 1966), Garrigue (1987) and Ajisaka (1991). In their catalog of the Ma- rine Benthic Algae from New Caledonia (based on the previous records), Garrigue and Tsuda (1988) enumerated 130 species of green algae, 59 species of brown algae and 147 species of red algae. However, to date there have been few studies on minute endophytes or epiphytes on macroalgae in New Caledonia. This is because it is diffi- cult to find microscopic algae living within or on the tissue of the preserved dried plants specimens previously collected. While in New Caledonia on a study trip the first author collected fresh samples with the aim of examining the microscopic ma- rine algae of New Caledonia. -

This represents the frst inventory encompass- ing the three major macroalgal classes (Phaeophyceae, Florideophyceae and Ulvophyceae) for the little-known Malagasy marine fora. Combining morphological and DNA-based approaches, we report from our collection a total of 110 species from northern Madagas- car, including 30 species of Phaeophyceae, 50 Florideophyceae and 30 Ulvophyceae. Bar- coding of the chloroplast-encoded rbcL gene was used for the three algal classes, in addi- tion to tufA for the Ulvophyceae. This study signifcantly increases our knowledge of the Malagasy marine biodiversity while augmenting the rbcL and tufA algal reference libraries for DNA barcoding. These eforts resulted in a total of 72 new species records for Mada- gascar. Combining our own data with the literature, we also provide an updated catalogue of 442 taxa of marine benthic -
