FUNGI-生物工程专业英语课程PPT

• Many insects also engage in mutualistic relationships with fungi
• As pathogens and parasites • As targets of mycoparasites • With algae and cyanobacteria
Symbiosis
• These interactions can be mutualistic or antagonistic in nature, or in the case of commensal fungi are of no apparent benefit or detriment to the host.
ECOLOGY
• Symbiosis
With Plant and Insects
• Mycorrhizal symbiosis between plants and fungi is one of the most well-known plant–fungus associations
• With Plants • With Insects
ECOLOGY
With algae and cyanobacteria
• Symbiosis • With Plants
• Lichens are a symbiotic relationship between fungi and photosynthetic algae or cyanobacteria.
• mycology is a relatively new science that became systematic after the development of the microscope in the 17th century.
• fungal spores were first observed by Giambattista della Porta in 1588, the seminal work in the development of mycology is considered to be the publication of Pier Antonio Micheli's 1729 work Nova plantarum genera.

DEFINITION
FUNGUS
• a member of the group of eukaryotic organisms
• include yeasts and molds and the more familiar mushrooms
• With Insects • As pathogens and parasites
As pathogens and parasites
• As targets of mycoparasites • With algae and cyanobacteria
• Many fungi are parasites on plants, animals (including humans), and other fungi such as Magnaporthe oryzae, Ophiostoma ulmi, Fusarium, Ustilago.
• Fungi can act as mycoparasites or antagonists of other fungi or become the target of infection by mycoviruses.
Kingdom Fungus Nhomakorabea• Christian Hendrik Persoon established the first classification of mushrooms by the binomial system.
• Elias Magnus Fries further elaborated the classification of fungi, using spore color and microscopic characteristics, methods still used by taxonomists today.
Ustilago
ECOLOGY
As targets of mycoparasites
• Symbiosis • With Plants • With Insects • As pathogens and parasites • As targets of mycoparasites • With algae and cyanobacteria
• The use of DNA sequencing technologies and phylogenetic analysis has provided new insights into fungal relationships and biodiversity, and has challenged traditional morphology-based groupings in fungal taxonomy.
HISTORY
Resent Stage
• The 20th century has seen a modernization of mycology that has come from advances in biochemistry, genetics, molecular biology, and biotechnology.
• a classified kingdom which is separate from the other eukaryotic life of plants and animals
