Sweet orange (Citrus sinensis L.) is one of the most economically important citrus crops in the world and is the most
commonly grown citrus fruit in the world. Nonetheless, its production is constantly threatened by pathogens that
cause considerable economic losses and severe social impacts including phytoplasma. Phytoplasma is an emerging
threat to sweet orange production which leads to severe yield losses worldwide. Phytoplasmas are phloem-limited
pleomorphic bacteria, mainly transmitted through leafhoppers but also by plant propagation materials and seeds.
This study aimed to evaluate the biochemical alterations in sweet orange plant as a response to phytoplasma
infection. Phytoplasma-infected plants in this study, showed symptoms, such as yellowing of leaves, stunted and
rolled foliage, unripened shoots and fruits, stunted roots or plant and &l.. View more»
