Phytoplasmas are significant procaryotic pathogenic bacterium without cell walls , which were formerly known as mycoplasma - comparable being , and belong to the Mollicutes class , Candidatus Phytoplasma genus . They are widely broadcast in plant and insects and can cause serious disease in essential food for thought crop , vegetables , yield tree , cosmetic plant , and trees , resulting in Brobdingnagian economical red ink .
To engagement , more than 100 phytoplasma diseases have been cover in China , which are distributed throughout the nation . Jujube witches'-broom , paulownia witches'-broom , wheat low midget , banana bunchy top , sugarcane white leaf , rice Orange River leaf , and mulberry nanus represent the phytoplasma diseases causing the most serious scathe in China . New phytoplasma disease and their strains are being report incessantly , indicate that phytoplasmas are more diverse than previously thought . Phytoplasmas are mainly carry by dirt ball vectors , such as leafhopper and planthopper , and can also be go around by graft or Cuscuta australis ( known as dodder ) . Mixed infections of phytoplasmas and viruses , bacteria , and spiroplasmas have also become a serious job in several crops and are responsible for for more synergetic expiration .
statistical distribution of master phytoplasma disease in China
With the continuous development and improvement of engineering science , molecular biologic catching has become the main proficiency for phytoplasma spying and identification . presently , research on phytoplasma diseases in China chiefly focuses on pathogen designation and classification and dirt ball vector and host diverseness ; however , there is less focus on pathogenicity , comparative genomics , and effect factors .
More enquiry attention has been paid to wheat drab dwarf phytoplasma , paulownia witches'-broom phytoplasma , jujube witches'-broom phytoplasma , and sugarcane white folio phytoplasma . Other phytoplasma diseases have been reported ; however , there have been no in - depth studies . In this newspaper , the chronicle and present situation of phytoplasma research , the position , distribution , and multifariousness of phytoplasma disease are sum up , and some potential research directions of phytoplasma in the future in China are proposed .
