Everything about Myxomycota totally explained
Myxomycota is a phylum of the Kingdom
Amoebozoa related to
protists. The name comes from the Greek
Myxo, meaning "slime", and mycota, meaning
fungus.
They are also known as the
plasmodial or
acellular slime molds.
Some would also consider
myxomycota as a kingdom unto itself, with an unsettled phylogeny because of conflicting molecular and developmental data.
Life Cycle
When a
Myxomycota spore germinates, it cracks, releasing an amoeba-like cell called a myxamoeba. The myxamoeba moves like an amoeba, and ingests food via
phagocytosis. Its food can include
microorganisms and nonliving organic matter. The myxamoeba will divide as it eats. When two myxamoeba of different mating strains (of different populations) find each other, that'll merge, forming a
zygote. The zygote itself won't divide, but rather it'll grow as its
nucleus divides, forming a large, multinucleate cell called a plasmodium. The plasmodium will continue to consume organic matter through phagocytosis. After some time, the plasmodium will travel to an open area and convert into a spore-bearing structure called a
sporangia. Spores will be released.
Reproduction
Myxomycota can form
swarm cells that
aggregate, fuse, form a
sporangia,
sporulate, and return to
amoebal or swarm cell stages. The
Myxomycota themselves are
haploid, and can switch between
amoeboid and
flagellated forms. The
gametes fuse into a
zygote, which then becomes a
plasmodium, which can produce fruit-like
spores.
