Root transcriptome analysis on the grape genotypes with contrast translocation pattern of excess manganese from root to shoot

摘要

The root-to-shoot transport of manganese (Mn) exhibited intra-specific characters in different grape genotypes. The majority of Mn was stored in the roots of the grape cultivar Jinshou, while it was mainly transferred to the shoots in the cultivar Combier. The aims of the present study was to reveal the complex interplay of gene expression endowing grape a high tolerance to excess Mn and to explore the relation of the expression of Mn transporters with the contrast root-to-shoot translocation pattern of excess Mn in different grape cultivars.
