Manitoba Co-operator: Is canola on the path to withstand verticillium?

High suberin levels — which is a natural biopolymer produced by the plant — could be one pathway to quantitative resistance, according to local research.

Plants use suberin to build cell walls, especially in roots. Because verticillium stripe infects canola through the roots, roots with thicker, more suberin-rich, cell walls could mean lower infection levels.

University of Manitoba doctoral student Shruti Kashyap made the suberin discovery while studying early-season moisture as it relates to verticillium stripe severity.
