One plant of Methylotrophic bacillus YH-18 for effectively preventing oriental cherry root knot and its Using
Technical field
The invention belongs to microorganisms technical fields, and in particular to one plant of Methylotrophic bud for effectively preventing oriental cherry root knot Spore bacillus (Bacillus methylotrophicus) YH-18 and its application.
Background technique
Oriental cherry is world-renowned ornamencal flower and tree, is under the jurisdiction of rosaceae (Rosaceae) cherry category (Cerasus), is distributed in north The warm area of hemisphere is north temperate zone plant.Oriental cherry system shallow root plant likes slightly sour loose fertile, well-drained soil and back The wet environment of wind direction sun.China possesses the oriental cherry resource of very abundant, non-considerably beyond Japan and neighboring countries, distribution Often extensively, it is all distributed from northeast to southwest, the high type of many of them ornamental value.In recent years oriental cherry because its plant type it is excellent Beauty, pattern is gorgeous, florescence duration is long and the extensive attention for the person that causes cultivating seedlings with high ornamental value, but with Being continuously increased for cultivated area, the area of suffered disease infestation also constantly expand, wherein with oriental cherry root knot, oriental cherry shothole disease And oriental cherry bleeding disease is the most serious.
Root knot is also referred to as root knot, root head cancer, clubroot, it is that as caused by Agrobacterium tumefaciems and have serious harm Bacterial disease, the disease have different degrees of generation in worldwide.Song Yu is bis- et al. the study found that soil Agrobacterium Host range it is very extensive, 93 sections 331 can be infected and belong to more than 643 different plants, wherein to endanger dicotyledon Based on, gymnosperm and monocotyledon can also be infected under specific condition.The infection way of root knot mainly passes through wound. Site of pathological change is mainly rootstock, lateral root and limb, and classical symptom is to form the different tumour of shape size in position of disease.Morbidity The symptom at position initial stage is to be initially formed milky, knob small such as beans, later with the growth knob of nursery stock by It gradually grows up, color is gradually deep, and surface becomes coarse by smooth, and then the quality become by internal lignifying is hard, shows dark brown Color becomes irregular shape after withered cracking, and knurl can surround rootstock or branch when which occurs serious.Illness is early The aerial part non-evident sympton of phase, nursery stock or tree body.With becoming larger for tumour, plant imaginary root tails off, tree vigo(u)r by dying down by force, into And yellowing leaf is caused, untimely defoliation.When falling ill serious, plant will receive influence in terms of nutrient absorption and Water Transportation, Plant strain growth slows down, and yield declines year by year, last until dead.
Oriental cherry root knot is caused by Agrobacterium tumefaciens, and very big loss is caused in production, is put within 1996 years Domestic forest quarantine object list.It is that spherical or hemispherical knob is generated at rhizome that oriental cherry, which obtains most apparent symptom after being ill, Knob is slowly grown up with the growth of nursery stock, has been seriously affected oriental cherry seedling growth speed and tree vigo(u)r, has been reduced ornamental article Matter and commodity value.Disease causes to fall leaves in advance when occurring light, can cause whole tree withered when serious, be known as oriental cherry by flower-grower " cancer ".
The current means of prevention for oriental cherry root knot is mainly based on chemical prevention and biological control.Utkhede RS etc. (1993) root for handling morbidity treelet with Kocide SD solution in apple field trial, as a result, it has been found that test group nodule number It is reduced compared with control group;Suppression of the Wang Huimin etc. (1995) by measurement fungicide and antibiotic to 3 kinds of bion Agrobacterium tumefaciems Bacterium effect, research find that streptomycin sulphate is all fine to the inhibiting effect of whole crown gall bacterium;Thiram is to biological type III crown gall agriculture All bacterial strains of bacillus have to be acted on compared with high inhibition;Benzylpenicillin sodium salt only has good inhibiting effect to biological type III;Other medicaments are equal Without effect.But it is long-term can bring a series of serious problems to environment and the ecological balance using chemical pesticide, and biological control In recent years by favor due to its is at low cost, pollution is small, control efficiency is significant, some scientific workers prevent and treat work in root knot Also variety classes and the significant biocontrol bacterial strain of control efficiency have been filtered out during work.Kerr is taught from peach root knot illness plant Isolated bacterial strain K84 in rhizosphere soil can effectively inhibit pathological form Agrobacterium tumefaciens to grow;Akira (2007) from Isolated grape agrobacterium VAR03-1, no pathogenicity on the grape nursery stock of Japan, and a kind of bacteriocin can be generated, it can To inhibit the formation of the tumour as caused by pathogenic grape agrobacterium G-Ag-27 on tomato and grape.
Bacillus has become the dominant strain of biocontrol microorganisms because cultivation cycle is short, convenient for production.It is a kind of production bud The gram-positive bacterium of spore, aerobic or amphimicrobian life, can generate heat-resisting, drought-enduring, uvioresistant and resist organic molten The endospore of agent, produced gemma can be made into the various dosage forms such as pulvis, wettable powder, and it is mixed with chemical pesticide after do not lose It is living, it is ideal screening of biocontrol agents object.
Clover is the model plant for being generally used for hospital's Bacteria infecting respiratory Pathogenicity.Laura in 2002 is with one Kind is inoculated with clover and mouse in the pathogen Psudomnoas aeruginosa that CF is often detected in patient body respectively, compares Result of study discovery, clover can replace the toxicity or even clover mould that mouse measures the bacterium to mammal as model plant Type shows sensitivity more higher than mouse models (Laura et al., 2002).Then, Steve has done similarly Bcc Compare test, it is found that disease incidence of the Bcc on clover is positively correlated with the result on mouse, can replace mouse as measurement Bcc is to the model plant of animal toxicity (Steve et al., 2003).With clover model can be simple and fast detect Bcc bacterium It is pathogenic whether strain has mammal, this has established solid foundation for our the safe utilization Bc in agricultural and environmental protection.
