Aug. 27 Flashcards
oldest ambiguous fossil of fungi
lower devonian rhynie chert
subkingdom of fungi that includes the division ascomycota and basidiomycota
dikarya
what are the characteristics of early fungi
simple, unicellular, with flagella
structure outside of cells of phylum basidiomycota
basidia/basidium
basal group of eukaryotes that is related to animals w/ structural similarity to the chytrids
choanoflagellates
they are known to cause animal diseases including potentially lethal infections of humans and plants
phylum basidiomycota or club fungi
fungal genomes can contain more than 200 copies of the cluster organized in repeating sequences
tandem repeats
separates individual copies of sequenced genes
intergenic spacer region (IGS) or non-transcribed spacer region (NTS)
defined as the assignment of organisms to a hierarchy of groups–genus, family, order
classification
term used to describe a broad group of fungi, animals, and choanoflagellates
opisthokonts
undetermined sequence from a distinctive species
operational taxonomic unit (OTU)
these are partitions successive compartments
along the length of the basidiomycete hyphae
dolipore septum
ets sequence use this ends of the cluster
5’ and 3’ ends of the cluster
it is the most common choice in molecular phylogenetic analysis of fungi
ribosomal - gene cluster
common name is club fungi
phylum basidiomycota
opisthokont include
fungi, animals, and choanoflagellates
three components of ribosomal - gene cluster
large subunit (SSU), small subunit (LSU), and internal transcribed spacers (ITS1 and ITS2)
the 3rd important characteristic of Basidiomycetes
clamp connections
distinct group of unicellular eukaryotes
fungi
the study of the evolutionary relationships between species and larger groupings of organisms
systematics
uses fluorescent dye
fluorescent in situ hybridization (FISH)
said to be partners with termites and leaf-cutter ants in a complex symbioses which feeds upon scale insects
phylum basidiomycota or club fungi
it is the identification, description, and naming of organisms
taxonomy
give the six phyla that are recognized in the current taxonomic arrangement of the fungi
phylums basidiomycota, ascomycota, glomeromycota, blastocladiomycota, chytridiomycota, neocallimastigomycota
works with ITS1 and ITS2 to encode for non-functional RNA molecules that are degraded when functional rRNA is transcribed
external transcribed spaces sequences (ETS)
