Cytokinin elevation caused by high light intensity contributes substantially to the increase of thermotolerance of rice plants

Light is a crucial factor affecting plant development. Rice (Oryza sativa) responses to high light (HL, 1300 μmol m−2 s−1, 27 °C) were characterized. HL significantly elevated root-born cytokinin, trans-zeatin in leaves due to transpiration stream. Despite only minor changes in abscisic acid (ABA) a...
