These spots have a slower development rate than the rest of the leaf.

In the epidermis of the sick plants characteristic structures can be seen easily with a microscope.

Temperature inactivation in juice 90 °C Transition: seed 8–10% from the beginning which is enough to star the silent infection.

Whether CGMMV is transmitted by pollen and pollinators is an important open question as of 2017[update].

[1] Liu et al., 2014 demonstrate simulated pollination does transmit vertically to the seed however this does not distinguish between mechanical transmission by the simulated pollination equipment and true vertical transmission within the pollen.
