MULTIDRUG RESISTANCE TRANSPORTER PROTEINS (EFFLUX SYSTEM) IN BACTERIA

The discovery and use of antibiotics to fight against bacterial infection have let to overrun many diseases. However overuse and/or incorrect use of the antibiotics increase the concentration of these compounds in the environment and create the selective pressure, which promotes antibiotic resistant microorganisms. Multidrug resistant pathogenic bacteria are a huge problem of the modern medical science because of the infections, which they cause, are almost incurable.

AUX/LAX PERMEASES, ABC TRANSPORTERS AND PIN PROTEINS IN AUXIN POLAR TRANSPORT

Polar auxin transport is essential for normal plant growth and development. Auxin moves between plant cells through a combination of membrane diffusion and carrier-mediated transport. Recent studies have identified several classes of membrane proteins involved in auxin transport, and have started to uncover a system that regulates auxin flux through plant tissues via the subcellular asymmetric locali- zation of these proteins.
