"Mesoplasma florum strain L1, (ATCC 33453) formerly Acholeplasma florum, was isolated from the surface of the lemon tree flower. This is the type strain and will be used for comparative analysis with the pathogenic Mycoplasma species."
Description and significance
Mesoplasma florum is a small, fast growing, non-pathogenic BSL1 organism closely related to the Mycoplasmas. As a part of the family Mollicutes, it lacks a cell wall and has gone through natural genome minimalization. Mesoplasma florum has an approximately 800kb genome  and has a doubling time of 40 minutes . It is possible that Mesoplasma florum is a plant pathogen, as it was discovered on the surface of a lemon tree flower . Due to small genome size, Mesoplasma florum has evolved to have reduced metabolic pathways .
For the reasons stated above, Mesoplasma florum is an important organism in synthetic genomics because of its ease of use and simplicity.
