The miR169z-NF-YA5-GPDHc1 module improves drought tolerance by increasing NAD levels to inhibit ROS production in Populus.

The microRNA169 (miR169) family and NF-YA transcription factors (TFs) are crucial for drought stress responses. However, the mechanisms by which these factors regulate reactive oxygen species (ROS) homeostasis under drought conditions remain inadequately characterized in Populus. Here, we identified an NF-YA TF, PagNF-YA5, from hybrid poplar 84 K (Populus alba × Populus glandulosa).

Evaluating the ability of the Wind Erosion Prediction System (WEPS) to simulate near-surface wind speeds in the Inland Pacific Northwest, USA.

Wind speed is one of the main control factors of wind erosion and dust emissions, which are major problems in arid and semiarid regions of the world. Accurately simulating highly precise hourly wind speeds is critical and cost-efficient for land management decisions with the goal of mitigating wind erosion and land degradation. The Wind Erosion Prediction System (WEPS) is a process-based, daily time-step model that simulates changes in the soil-vegetation-atmosphere.

Windblown sediment transport and loss in a desert-oasis ecotone in the Tarim Basin.

The Tarim Basin is regarded as one of the most highly erodible areas in China. Desert comprises 64% of the land use in the Basin, but the desert-oasis ecotone plays a prominent role in maintaining oasis ecological security and stability. Yet, little is known concerning the magnitude of windblown sediment transport in a desert-oasis ecotone.
