Model Organisms used for Research

Much of what scientist know about their current scientific knowledge comes from research on various organisms. Following contents describes some model organisms and what scientists have learned from those model organism studies.

Drosophila melanogaster (Fruit Fly);Heredity, Human disease, Animal development and circadian rhythms

Arabidopsis thaliana (Mouse-Ear Cress); Control of gene expression, Genome duplication, Disease resistancei, Response to the environment, Hormones, Circadian rhythms and flowering.

Caenorhabditis elegans (Nematode); Animal development, Apoptosis, Muscle function, Drug development, aging and origin of sex.

Neurospora crassa (Red Bread Mold); Crossing over, One-gene/one-enzyme hypothesis, Circadian rhythms and gene regulation.
