SECRETION SYSTEMS IN PLANT PATHOGENIC BACTERIA
Abstract :
Plant pathogenic gram-negative ve positive bacteria that cause disease in plants have effector proteins. These proteins pass into the plant cell via special bacterial secretion systems. Plant pathogenic bacteria implement extracellular secretion by their own protein transport systems. The base sequence analyses have shown that extracellular secretion systems in plant ve animal pathogenic bacteria are to a large extent similar. According to these similarities, secretion systems in gram negative bacteria can be classified into five groups: Type I, Type II, Type III, Type IV ve Type V, whereas gram-positive bacteria have three groups: Type I, Type II ve Type V. Most of plant pathogenic gram-negative bacteria have type III secretion system. This secretion system is encoded by hrp (for hypersensitive response ve pathogenicity) genes, which are so named because they are required for bacteria in order to cause disease in susceptible plants ve to elicit the hypersensitive response in resistant plants.
