Liberibacter spp., and Ca. The Asian form, Ca. Herein a review of insect vectors of plant pathogenic fastidious prokaryotes is provided by the authors. Temperature also shows a great influence in the parasite-host relationship between the bacteria and the insect vector, affecting how it is acquired and transmitted by the insects. Some other plant diseases caused by these bacteria are: citrus greening, elm leaf scorch, potato leaflet stunt, etc. Even so, some types of phytopathogenic bacteria, e.g., fastidious phloem- or xylem-inhabiting bacteria, which for several years were thought to be rickettsia-like organisms (RLO), were only discovered in 1972; more of them, e.g., Serratia, Sphimgomonas, Candidatus liberatus, and the papaya bunchy top bacterium, are still being discovered as plant … sisay says: July 31, 2018 at 6:54 pm i am happy withn your explanations.
