combat nucleotide 'invaders' such as viruses, trasposable elements and transgenes. The
quantity and quality of light perceived by a plant is a constant environmental stimulus
refining cell homeostasis and RNA silencing mechanism seems not to be an exception In
our recent paper in BMC Plant Biology we documented that light intensity, in physiological
ranges, positively affects silencing initiation and spread. 1 Here, we show that virus induced …
