Chloroplast and Mitochondria

Abstract

Photosynthesis is a crucial process for plants on earth that changes light energy to chemical energy. Virus infection can cause dramatic photosynthesis changes: respiration and the translocation of carbohydrates and other substances around the host plant. Chlorosis in virus-infected leaves like Barley Yellow Dwarf Virus (BYDV- PAV).infection can result from damage to chloroplasts resulting from inhibition of photosynthetic activity. Our present study combines TEM and chlorophyll-level content in the presence of Gold nanoparticles (AuNPS) to explore the repair mechanism for the yellowing leaf symptom development caused by infection with BYDV- PAV by illustrating TEM micrographs; showing fragmentized grana, deformation of the myelin like bodies (MLB), many vesicles; osmiophilic lipid granules/plastoglobulus, starch body, and plasmolysis in the chloroplast, distribution of AuNPs & VLPs near and inside the chloroplast.
