An obvious way to increase nutrient remobilization is to increase the expression or activity of transporter genes responsible for the transport of nutrients to the grain.
R. rickettsii appears to respond by up regulating many proteins with homology to transporters which are potentially involved in the transport of nutrients from the cytoplasm of host cells.
Due to the impermeability of the OM, gram-negative bacteria have evolved three major classes of outer membrane proteins to facilitate the transport of nutrients into the cell: active transporters, general porins, and diffusion-driven specific transporters [2].
Transplacental transport of nutrients is carried out by various proteins such as glucose transporters (GLUT) located in the cell membranes of maternal and fetal structures [ 15, 16].
The bacteria attack the trees' phloem, or vascular tissue, preventing the transport of nutrients.
The cytoplasmic membrane carries out many necessary cellular functions, including energy generation, protein secretion, chromosome segregation, and efficient active transport of nutrients.
The gradient of protons is used directly by the cell for many processes, including the active transport of nutrients and the rotation of flagella.
Changes in precipitation regimes and extreme events can cause ecosystem transitions, increase transport of nutrients and pollutants to downstream ecosystems, and overwhelm the ability of natural systems to mitigate harm to people from these events.
The shape and hydrological properties may also affect transport of nutrients such as nitrogen.
The transport of nutrients in the capillary network is convection dominated.
pH of the media affect the reaction environment, enzymatic process and transport of nutrients across the cell membrane of bacteria.
