Size
Studies by G. Salazar et al. and cited by Soltis indicated that the Lemna has a very small genome size (1C = 0.60 pg, where C = the one chromosome set). Compare this for example to to a primitive diploid wheat, Triticum monococcum (1C = 6.23 pg). The small genome size of Lemna compares to that of early flowering plants. -
Genome Sequencing
Andrey Mardanov and colleagues at the Bioengineering Center of the Russian Academy of Sciences in Moscow announced the sequencing of the Lemna minor chloroplast Genome. -
Giant Genome Sequencing
US Department of Energy (DOE) Joint Genome Institute announced the Community Sequencing Program will fund the sequencing the genome of the giant duckweed, Spirodela polyrhiza, which has a genome size similar to that of Arabidopsis (150 MB). This Duckweed Genome Project was a priority project for DOE in 2009. The research intended to facilitate new biomass and bioenergy programs. -
DNA Sequence
W. Wang and Joachim Messing at Rutgers published a DNA sequence comparison of three duckweed chloroplast genomes Spirodela polyrhiza, Wolffiella lingulata and Wolffia australiana. -
Mitochondrial Genome
Wang, Wu and Messing published the mitochondrial genome of Spirodela. -
Overall Study Published
An international team led by Messing publishes the complete an overall study of the Spirodela genome and interprets their findings to explain important anatomical and physiological attributes of the duckweeds.
