Intrahost mechanisms governing emergence of resistance-breaking variants of Potato virus Y.

Virology - 1 Mar 2013

Acosta-Leal Rodolfo, Xiong Zhongguo

Abstract excerpt

The emergence of resistance breaking (RB) variants starting from the avirulent Potato virus Y NN strain (PVY(NN)) was analyzed after imposing different selective host constraints. Tobacco resistance to PVY(NN) is conferred by va in both NC745 and VAM genotypes, but VAM carries an extra resistance gene, va2. RB-variants emerged only in NC745 and unexpectedly accumulated higher in the original host, tobacco B21,...
