Potato Negatively Regulates Cu/Zn-SOD Response to Drought Tolerance.

One of the main impacts of drought stress on plants is an excessive buildup of reactive oxygen species (ROS).

At the heart of antioxidant enzymes is superoxide dismutase (SOD), which is the first antioxidant enzyme to function in the active oxygen scavenging system.

Stu-miR827-Targeted Transcription Factor Negatively Regulates Drought Tolerance of Potato by Increasing Leaf Stomatal Density.

Stomata are specialized portals in plant leaves to modulate water loss from plants to the atmosphere by control of the transpiration, thereby determining the water-use efficiency and drought resistance of plants. Despite that the stomata developmental progression is well-understood at the molecular level, the experimental evidence that miRNA regulates stomata development is still lacking, and the underlying mechanism remains elusive. This study demonstrates the involvement of stu-miR827 in regulating the drought tolerance of potato due to its control over the leaf stomatal density.

MicroRNAs Are Involved in Regulating Plant Development and Stress Response through Fine-Tuning of TIR1/AFB-Dependent Auxin Signaling.

Recently, microRNAs (miRNAs), a type of short non-coding RNA, have emerged as master regulators of the auxin response pathways by affecting auxin homeostasis and perception in plants. The combination of these miRNAs and the autoregulation of the auxin signaling pathways, as well as the interaction with other hormones, creates a regulatory network that controls the level of auxin perception and signal transduction to maintain signaling homeostasis.
