For example, many plants respond to changes in day length and learn when to start flowering. Studying these subtleties offers hope that humans will be able to grow crops in the future as climate change makes weather more extreme, scientists say. In August, a team of European scientists discovered exactly how plant roots change their shape to maximize water absorption. They usually branch horizontally. However, if contact with water is lost, the process is suspended. Roots will resume branching only after reconnecting with moist soil.
Scientists attribute this process to water signaling. Water Signals moible number data Water signals are a way for plants to sense where water is located without directly measuring its levels. In this, they are helped by molecules that move along with the water through tiny pores inside the plant. When water enters a plant's roots, it travels through the outer cells. They contain a hormone that promotes branching auxin. The absorption of water activates it. If its access is cut off, the root has to rely on water from its own resources.
This redirects the movement of water so that it moves outward, disrupting the flow of auxin. Instead, another hormone kicks in. It closes all the small pores connecting the root cells. on a ship, which close automatically in the event of a fire. Root cells are isolated from each other, the free movement of auxin is stopped, and root branching is hindered. This simple system allows the roots to precisely adjust their shape to the water conditions.
