A Critical Review on Defense Mechanisms of Plants against Bacterial Pathogens: From Morphological to Molecular Levels
Author(s): Tibebu Belete*
Better understanding of plant defense mechanism is crucial for improving crop health and yield. Plant defense
against bacterial pathogens results from a complex combination of structural plant characteristics and induced
biochemical reactions. In addition to the constitutive defense, plants may perceive directly or indirectly the presence
of a bacterium and subsequently induce plant defense responses. These inducible biochemical reactions tend to
create protective physiological conditions to limit bacterial growth and invasion in the host tissues. The inducible
plant defense starts when a particular bacterial molecule or its structural feature is recognized by trans-membrane
protein recognition receptors (PRRs) on plant cell surface. The recognition is based on conserved features of
molecules of bacterial origin, namely pathogen associated molecular pattern.. View more»
