title: [Effects of Acaulospora spinosa on plant growth and lycopene related genes (psyl and psy2) expression of tomato].
abstract: In the present study, an arbuscular mycorrhizal fungus (AMF) strain Acaulospora spinosa XJ27, previously isolated from tomato root rhizosphere in Xinjiang' s suburbs, was used to inoculate root systems of tomato cultivar "Micro-Tom". The biomass, contents of chlorophyll in leaves and lycopene in fruits of plants between the treatments with and without XJ27 were analyzed, and the expression level of lycopene biosynthesis relevant genes (psyl and.psy2) investigated by semi quantitative-PCR and real-time PCR. The results indicated that the application of XJ27 to the rhizosphere of tomato increased the biomass and yield of the treated plants, the expression of psyl and psy2 was improved, and the amount of lycopene accumulation in tomato. It suggested Acaulospora spinosa XJ27 has a great potential in utilization.
