Introduction - PAMP Signals in Plant Innate Immunity: Signal Perception and Transduction - page 8

result of rapid changes in pathogen populations and the sheer diversity of pathogen
infection mechanisms. Recently several bioengineering and molecular manipula-
tion technologies have been developed to activate the 'sleeping' plant innate immune
system, which has potential to detect and suppress the development of a wide range
of plant pathogens in economically important crop plants (Lacombe et al. 2010 ).
Enhancing disease resistance through altered regulation of plant immunity signaling
systems would be durable and publicly acceptable (Yamamizo et al. 2006 ; Shao
et al. 2008 ; Gust et al. 2010 ; Lacombe et al. 2010 ). Strategies for activation and
improvement of plant immunity aim at enhancing host capacities for recognition of
potential pathogens, at boosting the executive arsenal of plant immunity, and inter-
fering with virulence strategies employed by microbial pathogens (Gust et al. 2010 ).
Major advances in our understanding of the molecular basis of plant immunity and
of microbial infection strategies have opened new ways for engineering durable
resistance in crop plants (Gust et al. 2010 ; Huffaker et al. 2011 ). This topic describes
the most fascinating PAMP-PRR signaling complex and signal transduction
systems. It discusses the highly complex networks of signaling pathways involved
in transmission of the signals to induce distinctly different defense-related genes to
mount offence against different pathogens.
