3 How Many Kingdoms? Multicellular Animals MyxozoansProtozoans Tracheophytes Bryophytes True Fungi Slime Molds Red algae Brown Algae Green Algae Chrysophytes EuglenoidsArchezoans Archaebacteria Bacteria Original Cell Extant Extinct Long Time with Prokaryotes only

4 Bacteria - Eubacteria Ancient fossils 3.5 billion years b.p. Archetype for prokaryotic organisms –Phototrophs –Chemoautotrophs –Heterotrophs –Saprobes –Parasites (bacteria benefit, host harmed) –Commensals (bacteria benefit, host unharmed) –Mutualists (bacteria and host both benefit) Unicellular, colonial, filamentous Bacillus, coccus, spirillum

6 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria ChlamydiasSpirochetesGram PositiveCyanobacteria to Domains Archaea and Eukarya

7 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria Gram-negativephotoauto-, chemoauto-, hetero-trophs symbionts, parasites Rhizobium-legumes: N 2 fixation Agrobacterium-host: Recombinant DNA Rickettsias: Rocky Mountain Fever likely source of mitochondrion by endosymbiosis

8 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria Gram-negativephotoauto-, chemoauto-, hetero-trophs nutritionally diverse Nitrosomonas in soil: NH 4 + NO 2 - ammonium nitrite

9 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria Gram-negativephotoauto-, chemoauto-, hetero-trophs Photosynthetic: Chromatium CO 2 + H 2 S CH 2 O + S (solid) Heterotrophic: Legionella-Legionnaires disease Enterics: Escherichia coli in your intestine Salmonella food poisoning Vibrio cholerae cholera

10 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria Gram-negativephotoauto-, chemoauto-, hetero-trophs Myxobacteria: slime secretion, aggregation, spores Bdellovibrios: rapid locomotion 100 m/sec penetrate prey bacteria 100 rps

11 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria Gram-negativephotoauto-, chemoauto-, hetero-trophs Helicobacter pylori: human stomach ulcers

12 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria Chlamydias Gram-negative parasites inside animal cells Chlamydia trachomatis: blindness Non-gonococcal urethritis: common STD (most-common in USA!)

13 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria ChlamydiasSpirochetes Helical heterotrophs to 0.25 mm long but very thin! Rotational bacterial filament Free-living and pathogens: Treponema pallidum = syphilis Borrelia burgdorferi = Lyme disease

14 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria ChlamydiasSpirochetesGram Positive: very diverse Actinomycetes: branched chains tuberculosis, leprosy Soil: Streptomyces antibiotics Solitary: Bacillus, Clostridium anthrax, botulism Staphylococcus: clusters Streptococcus: chains hospital diseases Mycoplasmas 0.1 m walking pneumonia

15 Domain Prokarya Kingdom Bacteria Universal Ancestor Proteobacteria ChlamydiasSpirochetesGram PositiveCyanobacteria unicell, colony, filament photoautotrophs: CO 2 + H 2 O O 2 + CH 2 O heterocysts: N 2 fixation N 2 + H + + ATP NH 4 + likely source of chloroplast by endosymbiosis
