Salt and oxidative stresses uniquely regulate tomato cytokinin levels and transcriptomic response.

ABSTRACT: Cytokinins are well-known to be involved in processes responsible for plant growth and development. More recently, these hormones have begun to be associated with stress responses as well. However, it is unclear how changes in cytokinin biosynthesis, signaling, or transport relate to stress effects. This study examines in parallel how two different stresses, salt, and oxidative stress, affect changes in both cytokinin levels and whole plant transcriptome response. Solanum lycopersicum seedlings were given a short-term (6 hr) exposure to either salt (150 mM NaCl) or oxidative (20 mM H₂O₂) stress and then examined to determine both changes in cytokinin levels and transcriptome. LC-MS/MS was used to determine the levels of 22 different types of cytokinins in tomat
