Morphological and transcriptomic responses/acclimations of erect-type submerged macrophyte Hydrilla verticillata both at low-light exposure and light recovery phases.

ABSTRACT: Light intensity is a determinant for submerged macrophytes. Little is known about their molecular responses to low-light exposure, despite more informative and responsive than morphological traits. For erect-type submerged macrophytes, the stem is more crucial relative to the leaf in acclimation to low-light stress, but receives less attention. We determined morphological and stem transcriptomic responses/acclimations of Hydrilla verticillata to extremely and mildly low light (7.2 and 36 μmol photons m^-2 s^-1, respectively), that is, EL and ML, with the radiation intensity of 180 μmol photons m^-2 s^-1 as the control. Low-light exposure continued for 9 days, followed by a 7-day recovery phase (180 μmol photons m^-2 s^-1).
