Pospiviroid Infection of Tomato Regulates the Expression of Genes Involved in Flower and Fruit Development.

ABSTRACT: Viroids are unencapsidated, single-stranded, covalently-closed circular, highly structured, noncoding RNAs of 239⁻401 nucleotides that cause disease in several economically important crop plants. In tomato (Solanum lycopersicum cv. Rutgers), symptoms of pospiviroid infection include stunting, reduced vigor, flower abortion, and reduced size and number of fruits, resulting in significant crop losses. Dramatic alterations in plant development triggered by viroid infection are the result of differential gene expression; in our study, we focused on the effect of tomato planta macho viroid (TPMVd) and Mexican papita viroid (MPVd) infection on gene networks associated with the regulation of flower and fruit development. The expression of several of the genes were previously reported to be
