Definition of phytoplasma
: any of a group of bacteria that are related to mycoplasmas, cause plant diseases (such as aster yellows or elm yellows) by infecting phloem tissue, and are transmitted especially by homopteran insect vectors ◆Phytoplasmas are assigned temporary taxonomic names because they cannot yet be grown in artificial media as required in bacterial nomenclature for a fully valid name. For almost half a century, plant pathologists thought phytoplasmas were viruses. To this day, the inability to grow these bacteria outside plants or insects hinders efforts to get a handle on their biology and genomes. — Evelyn Strauss —called also mycoplasma-like organism
