Calcium modulation of bacterial wilt disease on potato.

Unlabelled: species complex (RSSC) is a phytopathogenic bacterial group that causes bacterial wilt in several crops, being potato () one of the most important hosts. The relationship between the potato plant ionome (mineral and trace elements composition) and the resistance levels to this pathogen has not been addressed until now. Mineral content of xylem sap, roots, stems and leaves of potato genotypes with different levels of resistance to bacterial wilt was assessed in this work, revealing a positive correlation between divalent calcium (Ca) cation concentrations and genotype resistance.
