Knowra Arabidopsis thaliana Arabidopsis thaliana Arabidopsis thaliana is a small annual flowering plant in the mustard family. Its short life cycle, compact genome, and ease of genetic manipulation make it a major model organism in plant biology.
Brassicaceae : Brassicaceae is a family of flowering plants that includes mustards, cabbages, and their relatives. Arabidopsis belongs to this family, whose shared traits help place it among familiar crops.
Agrobacterium-mediated transformation : Agrobacterium-mediated transformation uses Agrobacterium bacteria to introduce genetic material into plant cells. It provides a widely used route for adding or altering genes in Arabidopsis.
Photoperiodism : Photoperiodism is the response of an organism to the relative lengths of day and night. Arabidopsis helps reveal how seasonal day length controls flowering.
Crop plant : A crop plant is a species cultivated at scale for food, fiber, fuel, or other human uses. Arabidopsis is convenient for genetics but is not itself a major food crop.
Plant life cycle : A plant life cycle is the sequence from seed germination through growth, reproduction, and production of new seeds. Arabidopsis completes this cycle quickly, enabling experiments across successive generations.
T-DNA insertional mutagenesis : T-DNA insertional mutagenesis disrupts genes when transferred DNA inserts into a genome. Arabidopsis insertion collections let researchers connect disrupted genes to plant traits.
Plant hormone : A plant hormone is a signaling molecule that regulates growth, development, or responses to environmental conditions. Arabidopsis genetics has helped identify hormone pathways and their interactions.
Rice : Rice is a cereal grass cultivated worldwide and a major model for studying crop biology. Rice provides a contrasting model for grasses, whose biology differs from Arabidopsis.
Plant meristem : A plant meristem is a region of dividing cells that produces new organs or tissues. Arabidopsis meristems provide tractable systems for studying how plants keep growing.
Arabidopsis Information Resource : The Arabidopsis Information Resource is a database and portal for genetic, genomic, and biological information about Arabidopsis. It brings together reference data that make experiments and published results easier to interpret.
