AB  - *   The effects of three arbuscular mycorrhizal (AM) fungal isolates on the 
      expression of genes coding for sucrose synthase and on the nonstructural 
      carbohydrate (CHO) status of maize roots were evaluated. Gene expression and CHOs 
      were compared with their status in nonmycorrhizal plants grown at three soil 
      phosphorus (P) concentrations. *   The AM fungi and soil P supply influenced 
      expression of genes coding for sucrose synthase in maize roots. In general, up to 
      18 d after plant emergence, AM colonization increased the expression of genes 
      coding for sucrose synthase in maize roots, whereas increasing soil P decreased 
      this gene expression. The responses in gene expression were detected earlier than 
      other effects of AM fungal colonization, such as increased leaf P status and 
      plant growth response under limiting P supply. *   Higher sucrose-synthase gene 
      expression was not related to the concentration of sucrose, reducing sugars or 
      starch in the root tissue. *   Higher gene expression in AM roots confirms that 
      there is greater allocation of sucrose from nonstructural CHO pools in roots for 
      the AM fungus during the earliest phase of colonization than in nonmycorrhizal 
      roots.
