ABSTRACT
Medicinal plants and microorganisms show a close relationship,both of which are from the plantmicroorganism symbiont system and interact mutually.Microorganisms are closely related to the growth,reproduction and secondary metabolic activities of medicinal plants.The symbiotic relationship between medicinal plants and microbes is the hotspot of medicinal plants in recent years.This paper summarized the relationship between medicinal plants and microorganisms.It reviewed the effects of medicinal plant species and root exudates on the microbial community composition and diversity,the effects of medicinal plant rhizosphere microbes on plant growth,the specificity of microorganism and the molecular recognition mechanism of medicinal plants and microorganisms.This article also provided the basis for excavation and utilization of the mechanism of interaction between medicinal plants and microorganisms,which were significance for the effective use of microbial growth mechanism to improve the stress resistance of medicinal plants,to increase the yield and to improve the quality of medicinal plants.
ABSTRACT
The occurrence of Panax notoginseng diseases seriously constrains its economic yield,which has becoming one of the main factors that hinders the development of P.notoginseng.For the sustainable development of P.notoginseng industry,this study summarized the pathogens,incidence conditions,transmissions and control methods of main P.notoginseng diseases.This paper elaborated that the prevention of major P.notoginseng diseases should be a comprehensive strategy based on agricultural,chemical and biological control.The disease prevention-control system of focusing on prevention and comprehensive management should be established.The breeding of new varieties should be strengthened to improve the disease resistance and to promote the sustainable development of P.notoginseng industry.
