Original publication date 12 December 2019 (available online) Citation Stöck, M., Kratochvíl, L. (eds.): Paradigm shift in sex chromosome evolution. Abstracts of the workshop held in Berlin, Leibniz- Institute of Freshwater Ecology and Inland Fisheries (IGB), 19-22 September 2019. Berlin and Prague, 42 pp. Key words Vertebrates, sex chromosomes, sex determination, genetics, evolution, genomics, paradigm shift Abstract Explaining the variation in sex-determining mechanisms across the tree of life and understanding the evolution of sex chromosomes represent important goals in evolutionary biology. Many papers have followed the classical paradigm of differentiation pathways of sex chromosomes from autosomes. However, the evolutionary drivers and many other aspects of the differentiation of sex chromosomes still remain controversial. Thanks especially to the impact of new genomic techniques, the always vibrant field of sex chromosome evolution research is currently boosting. Results from recent functional and comparative studies across both model and especially non-model organisms challenge the traditional paradigms of sex chromosome evolution. Therefore, this is the perfect time to open a forum for discussion, summary and reappraisal of our understanding of this field. The aim of the meeting is to gather evolutionary biologists with different backgrounds (developmental biology, population genetics, genomics, evolutionary ecology) to formulate and address fundamental questions and to uncover gaps in our understanding of sex chromosome evolution with a focus on vertebrates. We will unite people who use different approaches and means to study vertebrate sex evolution as well as applications (e.g. in endocrine disruption research, aquaculture, and species evolution/biodiversity).

  • Fungi-Rhizopus
    Characters of Fungi Some of the most important characters of fungi are as follows: 1. Occurrence 2. Thallus organization 3. Different forms of mycelium 4. Cell structure 5. Nutrition 6. Heterothallism and Homothallism 7. Reproduction 8. Classification of Fungi. 1. Occurrence: Fungi are cosmopolitan and occur in air, water soil and on plants and animals. They prefer to grow in warm and humid places. Hence, we keep food in the refrigerator to prevent bacterial and fungal infestation. 2. Thallus organization: Except some unicellular forms (e.g. yeasts, Synchytrium), the fungal body is a thallus called mycelium. The mycelium is an interwoven mass of thread-like hyphae (Sing, hypha). Hyphae may be septate (with cross wall) and aseptate (without cross wall). Some fungi are dimorphic that found as both unicellular and mycelial forms e.g. Candida albicans. 3. Different forms of mycelium: (a) Plectenchyma (fungal tissue): In a fungal mycelium, hyphae organized loosely or compactly woven to form a tissue called plectenchyma. It is two types: i. Prosenchyma or Prosoplectenchyma: In these fungal tissue hyphae are loosely interwoven lying more or less parallel to each other. ii. Pseudoparenchyma or paraplectenchyma: In these fungal tissue hyphae are compactly interwoven looking like a parenchyma in cross-section. (b) Sclerotia (Gr. Skleros=haid): These are hard dormant bodies consist of compact hyphae protected by external thickened hyphae. Each Sclerotium germinates into a mycelium, on return of favourable condition, e.g., Penicillium. (c) Rhizomorphs: They are root-like compactly interwoven hyphae with distinct growing tip. They help in absorption and perennation (to tide over the unfavourable periods), e.g., Armillaria mellea.

  • The Evolutionary Maintenance of Sexual Reproduction: the Solutions Proposed for a Longstanding Problem
    J. Genet. Vol. 69, No. 1, April 1990, pp. 1-10. 9 Printedin India. The evolutionary maintenance of sexual reproduction: The solutions proposed for a longstanding problem STEPHEN C. STEARNS Zoology Institute, Rheinsprung 9, CH-4051 Basel, Switzerland Abstract. The evolutionary maintenance of mixis is one of the major unsolved problems in modern biology. This paper reviews the phenomenon of sex, the hypotheses for its maintenance, and recent evidence bearing on the hypotheses. One elegant experiment supports the idea that bacterial transformation, an analogue and possible forerunner of eukaryotic mixis, functions as a repair mechanism. All mechanisms that produce a short- term advantage for sex in eukaryotes and that are supported by experimental results rely on strong genotype by environment interactions for fitness. While many environmental factors are involved, most prominently parasites, disease, and coarse-grained environmental heterogeneity of other sorts, each is effective only insofar as it is involved in a genotype by environment interaction for fitness. Keywords. Sexual reproduction; genotype by environment interaction; mixis; evolution of SeX. 1. Introduction The existence of sexual reproduction was no-puzzle for evolutionary biologists until 1962, when the publication of Wynne-Edwards' book signalled one of the most productive mistakes in the history of biologyl Wynne-Edwards made explicit and clear a kind of group-selectionist thinking that had previously been too implicit and diffuse to stimulate objections. Prior to that, one could explain sexual reproduction as an adaptation that endowed a population or species with the ability to evolve more rapidly than would asexual reproduction. After that, as part of the reaction to the criticisms of group selection (e.g.

  • Sexual Selection, Sexual Conflict and the Evolution of Ageing and Life Span
    Functional Ecology 2008, 22, 443–453 doi: 10.1111/j.1365-2435.2008.01417.x THEBlackwell Publishing Ltd EVOLUTIONARY ECOLOGY OF SENESCENCE Sexual selection, sexual conflict and the evolution of ageing and life span R. Bonduriansky*, A. Maklakov, F. Zajitschek and R. Brooks Evolution and Ecology Research Centre, School of Biological, Earth and Environmental Sciences, University of New South Wales, Sydney NSW 2052, Australia Summary 1. Classic evolutionary models interpret ageing as a cost of reproduction, but evolutionary research has thus far largely neglected the conceptual links between the evolution of ageing and a key mode of selection on male and female reproductive strategies – sexual selection and sexual conflict. 2. We synthesize ideas and evidence linking sex and ageing, and make the case that a focus on this fascinating problem will ultimately lead to a more complete understanding of both the evolution of ageing and the evolution of sexual strategies. 3. The primary and secondary differentiation of male and female reproductive strategies is expected to produce sex-specific optima for traits that affect longevity and ageing rate, often favouring a ‘live fast, die young’ strategy in males, relative to females, although numerous exceptions to this pattern are observed and sex-differences in ageing rate, in particular, remain poorly understood. 4. Conversely, environmental factors that influence life expectancy or ageing rate can thereby determine the magnitude or even sign of sexual selection. 5. Sexual conflict is expected to displace the sexes from their sex-specific life-history optima through sexually antagonistic interactions, as well as sex-specific selection on loci expressed in both sexes.

    KINGDOM PLANTAE Algae Moss & Fern NOTES Characteristics: • Eukaryotes • Autotrophs – have chlorophyll in chloroplasts for photosynthesis • Cell walls made of cellulose • Unicellular & multicellular • Sexual & asexual reproduction • A life cycle (L. C.) called alternation of generations Life Cycle: Alternation of Generations Plant switches back and forth between the sporophyte and the gametophyte generations (they alternate). 2 Phases: 1. Sporophyte generation = Diploid (2N) = Produces spores by meiosis. 2. Gametophyte generation = Haploid (N) = Produces gametes (sex cells). SPOROPHYTE (2N) zygote 2N 2N fertilization meiosis gametes N N N spores GAMETOPHYTE (N) AQUATIC PLANT REPRODUCTION: ALGAE A. Asexual reproduction 3 types: 1. Fragmentation = piece breaks off cell body and grows into a new individual. 2. Asexual spores = haploid 3. Mitotic division = simple cell division –single celled algae. B. Sexual reproduction The two gametes fuse to form a zygote There are two types of gametes: identical and different 1.Isogamy = identical gametes = isogametes = same size and structure. When isogametes fuse = conjugation. Isogametes are differentiated by + and – strain (like fungus) 2. Heterogamy = different gametes = different size and structure. Larger gamete = egg; smaller gamete = sperm. When egg and sperm fuse = fertilization. Algae have accessory pigments Function: • Protect chlorophyll • Absorb additional light for algae’s photosynthetic machinery. This allows algae to live in deeper water than chlorophyll alone • Gives algae its colour AQUATIC PLANTS Benefits of living in water Problem with living in water • Won’t dry out • No conductive tissue • Water provides support for the • No true roots, stems, or leaves plant • Provides nutrients • They must be thin to absorb nutrients & water through leaf- like structures • Helps disperse spores • Helps gametes meet Ecological roles/ uses of algae • Food source • Supply O2 to earth - phytoplankton • Gelatin for pie filling • Used to make agar plates (for study of bacteria!).

    BIOLOGY AND DIVERSITY OF VIRUSES, BACTERIA AND FUNGI (PAPER CODE: BOT 501) By Dr. Kirtika Padalia Department of Botany Uttarakhand Open University, Haldwani E-mail: [email protected] OBJECTIVES The main objective of the present lecture is to cover the topic and make it easy to understand and interesting for our students/learners. BLOCK – III : FUNGI – I Unit –13 : Reproduction in Fungi In this lecture, we will discuss about the various methods of reproduction adopted by the fungi. CONTENT ❑ Reproduction in fungi ❖ Vegetative Reproduction • Fission • Budding • Fragmentation • Sclerotia • Rhizomorphs ❖ Asexual Reproduction • Endogenous Spores • Exogenous Spores ❖ Sexual Reproduction • Planogametic Copulation • Gametangial Contact • Gametangial Copulation • Spermatization: • Somatogamy ❑ Sexual Incompatibility ❑ Sexual Pheromones ❑ Key Points of The Lecture ❑ Terminology ❑ Some Assessment Questions REPRODUCTION IN FUNGI ❖ Reproduction may be define as a process in which individual species increase their number by producing the progeny. ❖ Fungi are achlorophyllas, heterotrophic eukaryotic thallophytes, which adopted the various methods of reproduction. ❖ When the fungal mycelium has reached a certain stage of maturity and has accumulated reserve food material, it start reproduction. ❖ Reproduction involves the production of new individuals resembling the parent or parents. ❖ In fungi, reproduction is of three kinds; • Vegetative reproduction • Asexual reproduction • Sexual reproduction ❖ Many mycologist, however, included all methods of reproduction (vegetative and spore formation) which do not involve union of nucli or sex cell or sex organs under asexual or somatic reproduction. ❖ During asexual and sexual reproduction processes spores are the essential structures. The spores formed after meiosis are called meiospores (e.g., ascospores, basidiospores and sporangiospores) and those resulting from mitosis, called mitospores (e.g., mitospores, zoospores, aplanospores, conidia, uredospores).

  • Evolution of Sex Why Is Sexual Reproduction So Commonplace?
    Honors Project by Aaron Weinblatt Evolution of Sex Why is Sexual Reproduction so Commonplace? Introduction The topic of reproduction has been one of my interests for a while. Evolution, in general, has always fascinated me and I pursued more knowledge of the topic with extracurricular reading and research. I was inspired to write this honors project after reading The Red Queen: Sex and ​ the Evolution of Human Nature by Matt Ridley during the summer before sophomore year. ​ Ridley pointed out that initially, all life forms reproduced asexually. As lifeforms evolved, so did reproduction and eventually, sexual reproduction was practiced. Humans have since evolved their human nature, however, the two forms of reproduction have stayed the same. This begs the question of why life forms have two separate forms of reproduction and why we humans, the most recent species, reproduce sexually. Life has been around for approximately 4.250 billion years and it wasn’t until about 1.250 billion years ago that life began reproducing sexually. Before then, life forms on earth reproduced asexually. Around nine hundred million years after the first sexually reproducing organisms evolved, land life emerged. An estimated 99.99% of all eukaryotes1 can (and often do) reproduce sexually including us humans. So how and why did life begin reproducing sexually after three billion years and why has it prevailed? The explanation for the predominance of sexual reproduction is inconsistent and includes many theories, however, by studying and comparing the facts, a conclusion can materialize. How Sexual Reproduction Works Unlike asexual reproduction, sexual reproduction produces offspring that resemble their ​ ​ parents but are not identical.

  • CLASSIFICATION of LIVING ORGANISMS the Main Purpose Of
    CLASSIFICATION OF LIVING ORGANISMS The main purpose of the classification is to group the living things on the earth according to their kinship relations and make it easier to understand them in a regular system. The science that serves this purpose is known as Systematics or Taxonomy. Taxonomy consists of the words "taxis" (regulation, classification) and "nomos" (rule, rule, law) in Greek. The meaning of taxonomy is to set rules and laws on the classification. Systematics is the science dealing with the diversity of organisms and of any and all relationships among them. HISTORY OF CLASSIFICATION Aristotle (384-322 B.C.), was one of the first scientists to organize living things. He developed the first classification system, which divided all known organisms into two groups (Plants and Animals). The basis of this classification is to classify the living things based on their external appearances, living conditions, the basis of analogical organs and morphologic similarity. Nowadays, this classification has lost its validity. Phylogenetic classification is currently used in the classification of living things. The basic principles of scientific classification were first introduced by Carl Linnaeus (1707-1778) and he is known as the father of taxonomy. Linnaeus, like Aristotle, classified organisms according to their traits. The classification systems of both Aristotle and Linnaeus started with the same two groups (Plants and Animals). Linnaeus called these groups, kingdoms. Unlike Aristotle, Linnaeus divided the kingdom into levels (Class, Order, Genera, Species etc.). Organisms were placed in these levels based on traits, including similarities of body parts, physical form such as size, shape, and methods of feeding.
