Duckweed species have several key features that make it an attractive model system for research on plant biology:
Smallest flowering plant
Enables limited space requirements
Short generation time
Facilitates rapid experimentation and genetic studies.
Mainly propagates asexually
Allows for clonal propagation and controlled genetic backgrounds.
Simple body plan with few cell types
Especially in Wolffia; ideal for developmental and cellular differentiation studies.
Availability of sequenced genomes
Genomic data is publicly accessible for several species (see Genomics of Duckweed).
Relatively small genome size and low total gene number
Especially in Spirodela; simplifying genetic and transcriptomic analyses.
Easy cultivation in defined aqueous growth media
Promotes reproducibility and ease of experimental manipulation.
These features position duckweed as a powerful and efficient model for addressing fundamental questions in plant biology. Its simplicity, rapid growth, and genomic accessibility make it particularly suited for high-throughput studies, comparative genomics, and systems biology.
