8 wrz 2018 · We first review the evidence for the biophysical conditions necessary for foliar water uptake to occur, focusing on the plant and atmospheric water potentials necessary to create a gradient for water flow. We then consider the different pathways for uptake, as well as the potential fates of the water once inside the leaf.
8 lut 2010 · This qualitative and quantitative neontological approach to palaeobotany may be useful for interpreting the water-transport efficiencies and hydraulic limits in fossil plants. Large variations in atmospheric carbon dioxide levels are recorded in leaf stomatal densities, and may have had profound impacts on the water conservation strategies of ...
1 lis 2024 · Water transport and homeostasis are co-regulated by light intensity and VPD. Increased light intensity reduces water movement resistance under various VPDs. Different VPDs, coupled with high light intensity, enhance plant water transport. Light regulates the expression of SlTIPs and SlPIPs across VPDs.
It remains to be investigated how changes in water availability and water loss affect different tissues and cells in plants and how these biophysical signals are translated into chemical signals that feed into signaling pathways like abscisic acid response or organ development.
How does water move through plants to get to the top of tall trees? Here we describe the pathways and mechanisms driving water uptake and transport through plants, and causes of flow...
18 paź 2016 · Water transport in plants occurs along various paths and is driven by gradients in its free energy. It is generally considered that the mode of transport, being either diffusion or bulk flow, is a passive process, although energy may be required to sustain the forces driving water flow.
5 gru 2023 · Understanding the mechanisms underlying water uptake, transport, and balance in plants requires a clarity of several concepts, such as diffusion, osmosis, plasmolysis, and various components of water potential.
