Abstract excerpt
The effect of constitutive invertase overexpression on the arbuscular mycorrhiza (AM) is shown. The analysis of the enhanced potential for sucrose cleavage was performed with a heterozygous line of Nicotiana tabacum 35S::cwINV expressing a chimeric gene encoding apoplast-located yeast-derived invertase with the CaMV35S promoter. Despite the 35S promoter, roots of the transgenic plants showed no or only minor...
