Genome-Wide Identification, Characterization and Expression Profiling of ADF Family Genes in Solanum lycopersicum L.
The actin depolymerizing factor (ADF) proteins have growth, development, defense-related and growth regulatory functions in plants. The present study used genome-wide analysis to investigateADFfamily genes in tomato. Eleven tomatoADFgenes were identified and differential expression patterns were found in different organs.SlADF6was preferentially expressed in roots, suggesting its function in root development.SlADF1,SlADF3andSlADF10were predominately expressed in the flowers compared to the other organs and specifically in the stamen compared to other flower parts, indicating their potential roles in pollen development. The comparatively higher expression ofSlADF3andSlADF11at early fruit developmental stages might implicate them in determining final fruit size.SlADF5andSlADF8had relatively higher levels of expression five days after the breaker stage of fruit development, suggesting their possible role in fruit ripening. Notably, six genes were induced by cold and heat, seven by drought, five by NaCl, and four each by abscisic acid (ABA), jasmonic acid (JA) and wounding treatments. The differential expression patterns of theSlADFgenes under different types of stresses suggested their function in stress tolerance in tomato plants. Our results will be helpful for the functional characterization ofADFgenes during organ and fruit development of tomato under different stresses.
