Water district responds to extreme drought conditions. Gation Center released its newest map, showing that 58 percent of California is now in exceptional drought conditions, the most severe level.
Because free proline can increase the osmotic potential of cells, promote plant cells absorbing water. When the condition of drought, the increase of Pro can help cells absorb water. Proline acts as an osmoprotectant and that overproduction of proline results in the increased tolerance to osmotic stress in plants. It also enhances root biomass and flower development in transgenic plants under drought-stress conditions.
because it can displace the soil
They can in conditions of drought - but if they do so it is a sign that they are stressed or dying.
