When the thylakoid membrane of the chloroplast is is disrupted, the light reaction of photosynthesis would also be disrupted.
During the light reaction, light photons help cause the excitation of electrons in the photosystems of the chlorophyll in the chloroplast. This creates a series of reactions during which energy molecules are synthesized for the light-independent reaction of photosynthesis.
The light reaction happens in the thylakoid membrane of the chloroplast.
In the event of a disruption to the thylakoid membrane, the light reaction of photosynthesis would also be disrupted and the entire process of photosynthesis as a result.
Thus, the virus infection on individual plants will affect photosynthesis and thus, productivity.
