Plant priming, a state of enhanced defense, is induced by pathogens, microbes, or compounds. Primed plants exhibit faster and stronger cellular defense responses against various stresses, advancing our understanding of plant immunity.

Area of Science:

  • Plant pathology
  • Plant immunity
  • Microbiology

Background:

  • Plant priming is a physiological state induced by pathogens, beneficial microbes, or chemical treatments.
  • This state enhances plant defense responses against subsequent biotic and abiotic stresses.
  • While known for decades, recent years have seen significant advancements in understanding plant priming.

Purpose of the Study:

  • To summarize current knowledge on plant priming.
  • To review the role of priming in induced-resistance phenomena in plants.

Main Methods:

  • Review of existing literature on plant priming and induced resistance.
  • Synthesis of findings on the induction and outcomes of the primed state in plants.

Main Results:

  • Plant priming can be triggered by diverse agents including necrotizing pathogens, root-colonizing microbes, and various compounds.
  • Primed plants demonstrate accelerated and/or amplified activation of cellular defense mechanisms.
  • This enhanced defense is observed upon challenge by pathogens, insects, or exposure to abiotic stress.

Conclusions:

  • Plant priming represents a crucial mechanism for bolstering plant defenses.
  • Continued research is vital for harnessing priming for crop protection and resilience.
  • Recent progress has significantly deepened our comprehension of this phenomenon.
