Leaf-Associated Shifts in Bacterial and Fungal Communities in Response to Chicken Rearing Under Moso Bamboo Forests in Subtropical China
Article Leaf-Associated Shifts in Bacterial and Fungal Communities in Response to Chicken Rearing Under Moso Bamboo Forests in Subtropical China Xiaoping Zhang 1, Zheke Zhong 1,*, Xu Gai 1, Jiafu Ying 2, Weifen Li 2, Xuhua Du 1, Fangyuan Bian 1 and Chuanbao Yang 1 1 China National Bamboo Research Center, Key Laboratory of Resources and Utilization of Bamboo of State Forestry Administration, Hangzhou 310012, China; [email protected] (X.Z.); [email protected] (X.G.); [email protected] (X.D.); [email protected] (F.B.); [email protected] (C.Y.) 2 College of Animal Sciences, Zhejiang University, Hangzhou 310058, China; [email protected] (J.Y.); wfl[email protected] (W.L.) * Correspondence: [email protected]; Tel.: +86-0571-88860734 Received: 25 January 2019; Accepted: 25 February 2019; Published: 1 March 2019 Abstract: Integrated bamboo-chicken farming (BCF) systems are a traditional agroforestry pattern with large economic benefits in subtropical China. However, little is known regarding the effect of this integration on the bamboo leaf-associated microbiome, which can be very important for disease control and nutrient turnover. In the present study, we compared the leaf-associated bacterial and fungal communities of moso bamboo (Phyllostachys edulis) in a BCF system and an adjacent moso bamboo forest (MBF). The results showed that Cyanobacteria and Ascomycota were the predominant microbial phyla associated with bamboo leaves. Chicken farming under the bamboo forest significantly increased the bacterial and fungal alpha diversity (observed operational taxonomic units (OTUs) and Simpson’s index) associated with bamboo leaves. Principal components analysis (PCoA) further confirmed the shifts in the bacterial and fungal communities caused by chicken farming. -
RED ALGAE · RHODOPHYTA Rhodophyta Are Cosmopolitan, Found from the Artic to the Tropics
RED ALGAE · RHODOPHYTA Rhodophyta are cosmopolitan, found from the artic to the tropics. Although they grow in both marine and fresh water, 98% of the 6,500 species of red algae are marine. Most of these species occur in the tropics and sub-tropics, though the greatest number of species is temperate. Along the California coast, the species of red algae far outnumber the species of green and brown algae. In temperate regions such as California, red algae are common in the intertidal zone. In the tropics, however, they are mostly subtidal, growing as epiphytes on seagrasses, within the crevices of rock and coral reefs, or occasionally on dead coral or sand. In some tropical waters, red algae can be found as deep as 200 meters. Because of their unique accessory pigments (phycobiliproteins), the red algae are able to harvest the blue light that reaches deeper waters. Red algae are important economically in many parts of the world. For example, in Japan, the cultivation of Pyropia is a multibillion-dollar industry, used for nori and other algal products. Rhodophyta also provide valuable “gums” or colloidal agents for industrial and food applications. Two extremely important phycocolloids are agar (and the derivative agarose) and carrageenan. The Rhodophyta are the only algae which have “pit plugs” between cells in multicellular thalli. Though their true function is debated, pit plugs are thought to provide stability to the thallus. Also, the red algae are unique in that they have no flagellated stages, which enhance reproduction in other algae. Instead, red algae has a complex life cycle, with three distinct stages. -
Red Algae (Bangia Atropurpurea) Ecological Risk Screening Summary
Red Algae (Bangia atropurpurea) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, February 2014 Revised, March 2016, September 2017, October 2017 Web Version, 6/25/2018 1 Native Range and Status in the United States Native Range From NOAA and USGS (2016): “Bangia atropurpurea has a widespread amphi-Atlantic range, which includes the Atlantic coast of North America […]” Status in the United States From Mills et al. (1991): “This filamentous red alga native to the Atlantic Coast was observed in Lake Erie in 1964 (Lin and Blum 1977). After this sighting, records for Lake Ontario (Damann 1979), Lake Michigan (Weik 1977), Lake Simcoe (Jackson 1985) and Lake Huron (Sheath 1987) were reported. It has become a major species of the littoral flora of these lakes, generally occupying the littoral zone with Cladophora and Ulothrix (Blum 1982). Earliest records of this algae in the basin, however, go back to the 1940s when Smith and Moyle (1944) found the alga in Lake Superior tributaries. Matthews (1932) found the alga in Quaker Run in the Allegheny drainage basin. Smith and 1 Moyle’s records must have not resulted in spreading populations since the alga was not known in Lake Superior as of 1987. Kishler and Taft (1970) were the most recent workers to refer to the records of Smith and Moyle (1944) and Matthews (1932).” From NOAA and USGS (2016): “Established where recorded except in Lake Superior. The distribution in Lake Simcoe is limited (Jackson 1985).” From Kipp et al. (2017): “Bangia atropurpurea was first recorded from Lake Erie in 1964. During the 1960s–1980s, it was recorded from Lake Huron, Lake Michigan, Lake Ontario, and Lake Simcoe (part of the Lake Ontario drainage). -

During a study of the fungal diversity of 12 undiscovered taxa in Korea, two mucoralean strains, CNUFC-GWD3-9 and CNUFC-EGF1-4, were 13 isolated from specific habitats including freshwater and fecal samples, respectively, in Korea. The 14 strains were analyzed both for morphology and phylogeny based on the internal transcribed 15 spacer (ITS) and large subunit (LSU) of 28S ribosomal DNA regions. On the basis of their 16 morphological characteristics and sequence analyses, isolates CNUFC-GWD3-9 and CNUFC- 17 EGF1-4 were confirmed to be Gilbertella persicaria and Pilobolus crystallinus, respectively.To the 18 best of our knowledge, there are no published literature records of these two genera in Korea. 19 Keywords: Gilbertella persicaria; Pilobolus crystallinus; mucoralean fungi; phylogeny; morphology; 20 undiscovered taxa 21 22 1. Introduction 23 Previously, taxa of the former phylum Zygomycota were distributed among the phylum 24 Glomeromycota and four subphyla incertae sedis, including Mucoromycotina, Kickxellomycotina, 25 Zoopagomycotina, and Entomophthoromycotina [1]. -

Nature 484, 186–194 (12 April 2012) doi:10.1038/nature10947 The past two decades have seen an increasing number of virulent infectious diseases in natural populations and managed landscapes. In both animals and plants, an unprecedented number of fungal and fungal-like diseases have recently caused some of the most severe die-offs and extinctions ever witnessed in wild species, and are jeopardizing food security. Human activity is intensifying fungal disease dispersal by modifying natural environments and thus creating new opportunities for evolution. We argue that nascent fungal infections will cause increasing attrition of biodiversity, with wider implications for human and ecosystem health, unless steps are taken to tighten biosecurity worldwide. a.

Amoebozoa is a major, early-diverging lineage of eukaryotes, containing at least 2,400 species. At present, 32 mitochondrial genomes belonging to 18 amoebozoan species are publicly available. A dearth of information is particularly obvious for two major amoebozoan clades, Variosea and Tubulinea, with just one mitochondrial genome sequenced for each. The main focus of this review is to summarize features such as mitochondrial gene content, mitochondrial genome size variation, and presence or absence of RNA editing, showing if they are unique or shared among amoebozoan lineages. In addition, we underline the potential of mitochondrial genomes for multigene phylogenetic reconstruction in Amoebozoa, where the relationships among lineages are not fully resolved yet. With the increasing application of next-generation sequencing techniques and reliable protocols, we advocate mitochondrial -
Fungal Evolution: Major Ecological Adaptations and Evolutionary Transitions

Naranjo-Ortiz1 and Toni Gabaldon´ 1,2,3∗ 1Department of Genomics and Bioinformatics, Centre for Genomic Regulation (CRG), The Barcelona Institute of Science and Technology, Dr. Aiguader 88, Barcelona 08003, Spain 2 Department of Experimental and Health Sciences, Universitat Pompeu Fabra (UPF), 08003 Barcelona, Spain 3ICREA, Pg. Lluís Companys 23, 08010 Barcelona, Spain ABSTRACT Fungi are a highly diverse group of heterotrophic eukaryotes characterized by the absence of phagotrophy and the presence of a chitinous cell wall. While unicellular fungi are far from rare, part of the evolutionary success of the group resides in their ability to grow indefinitely as a cylindrical multinucleated cell (hypha). Armed with these morphological traits and with an extremely high metabolical diversity, fungi have conquered numerous ecological niches and have shaped a whole world of interactions with other living organisms. Herein we survey the main evolutionary and ecological processes that have guided fungal diversity. We will first review the ecology and evolution of the zoosporic lineages and the process of terrestrialization, as one of the major evolutionary transitions in this kingdom. Several plausible scenarios have been proposed for fungal terrestralization and we here propose a new scenario, which considers icy environments as a transitory niche between water and emerged land. We then focus on exploring the main ecological relationships of Fungi with other organisms (other fungi, protozoans, animals and plants), as well as the origin of adaptations to certain specialized ecological niches within the group (lichens, black fungi and yeasts). -
