Comparative transcriptome analysis of Citrus macrophylla tree infected with Citrus tristeza virus stem pitting mutants provides new insight into the role of phloem regeneration in stem pitting disease.

ABSTRACT: Stem pitting is a complex and economically important virus-associated disease of perennial woody plants. Molecular mechanisms and pathways occurring during virus-plant interaction that result in this phenomenon are still obscure. Previous studies indicated that different Citrus tristeza virus (CTV) mutants induce defined stem pitting phenotypes ranging from mild (CTVΔp13) to severe (CTVΔp33) in Citrus macrophylla trees. In this study, we conducted comparative transcriptome analyses of C. macrophylla trees infected with CTV mutants (CTVΔp13 and CTVΔp33) and a full-length virus in comparison to healthy plants as control. The mild CTV stem pitting mutant had very few differentially expressed genes (DEGs) related to plant defense mechanism and plant growth and development.
