Abstract
Biotic stress in plants: life lessons from your parents and grandparents
Highlights
In addition to their role during plant development, jasmonic acid (JA) and JA-related compounds, including methyl-jasmonate (MeJA) and jasmonate-isoleucine conjugate (JA-Ile), play essential roles during endogenous regulation of plant resistance to mechanical wounding and herbivory by modulating global changes in gene expression (Creelman and Mullet, 1997; Sheard et al, 2010)
Rasmann et al (2012) report transgenerational priming responses (TPR) in tomato and Arabidopsis induced by caterpillar herbivory (Helicoverpa zea and Pieris rapae) and application of MeJA
Consistent with an NPR1-dependent priming of Salicylic acid (SA)-inducible defense, a faster and stronger induction of SA-inducible defense genes such as PATHOGENESIS-RELATED GENE 1 (PR1), WRKY6, WRKY53, and WRKY70 was observed in P1 plants (Luna et al, 2012)
Summary
In addition to their role during plant development, JA and JA-related compounds, including methyl-jasmonate (MeJA) and jasmonate-isoleucine conjugate (JA-Ile), play essential roles during endogenous regulation of plant resistance to mechanical wounding and herbivory by modulating global changes in gene expression (Creelman and Mullet, 1997; Sheard et al, 2010). SA acts as an endogenous signal involved in systemic acquired resistance (SAR), an inducible resistance against a broad spectrum of pathogens including viruses, bacteria, and fungi that cause necrosis through rapid programmed cell death of infected cells, known as the hypersensitive response (Durrant and Dong, 2004).
