Webb7 apr. 2024 · SUTs transport sucrose to the other layer of the plasma membrane through the energy generated by membrane potential difference formed by H+ -ATPase, which has main functions: transport sucrose from the leaves to the phloem, and ultimately to the reservoir organs, such as tubers, roots, and fruits.

Webb28 mars 2024 · Drought is an adverse environmental factor for plant growth and development. Aquaporins play an influential role in water uptake and transport in plants. However, the function of PagPIP2;10 in response to drought stress remains largely unclear. Here, we report that the plasma membrane intrinsic protein PagPIP2;10 was in the cell … All terrestrial plants face the trade-off between water loss and carbon gain. Avoiding excessive water loss via stomatal closure during drought inevitably leads to reduced photosynthesis and carbohydrate production, which reduces source strength. Also, the turgor-related reduction of growth is one of the first drought … Visa mer Recent forest mortality events (Allen et al., 2010), combined with climate predictions of increasing drought severity and frequency in many areas (Allison et al., 2009), have motivated a new focus area of plant mortality … Visa mer The currently most accepted theory of phloem transport, the Münch hypothesis (Münch, 1930; see also Knoblauch and Peters, 2010) states that carbohydrates needed for … Visa mer The classical impermeable conduit model predicts that phloem transport could cease during drought even with active sources and sinks because of viscosity blockage in the … Visa mer The Hagen–Poiseuille law was originally developed to describe laminar flow in cylindrical tubes of impermeable walls (Bird et al., 2002) and the classical view of phloem transport, … Visa mer grange choral society christchurch
Plant-PET to investigate phloem vulnerability to drought in
Webb1 feb. 2024 · Phloem function and ability to transport resources is tightly controlled by the balance of carbon and water fluxes within the tree. As such, drought is expected to … WebbFör 1 dag sedan · It is known that the transport direction of phloem is from source to sink. This is inconsistent with our findings that PbHMGR1 can be transported upward from the root ( Fig. 4 ). The macromolecules such as RNA and protein are transported via the pressure flow system of the phloem to specific developing tissues, thereby maintaining … Webb19 okt. 2024 · If C demand for growth and maintenance is low in sink tissues, phloem transport will decrease, supported here by initially low secondary growth likely caused by drought-induced meristem inactivation and lower 13 C allocation to R root (Figs 4b, 5e–f). chinese white radish soup
