- The chaperonin CCT8 facilitates spread of tobamovirus infectionDaniela Fichtenbauer
Department of Biochemistry and Cell Biology, Center for Molecular Biology, University of Vienna, Vienna, Austria
Plant Signal Behav 7:318-21. 2012..Here we show that spread of tobamovirus infection is reduced in a cct8 mutant. This suggests that similar to KN1, viral movement proteins are unfolded and refolded during transport to gain functionality in the receiving cells...
