Impact of maize hormonal interactions on the performance of Spodoptera frugiperda in plants infected with Clavibacter michiganensis subsp. nebraskensis

In nature, plants interact with multiple organisms, below and aboveground. Although interactions of single biotic stressors are well characterized, knowledge how the immune system responds to is lacking. It known that two most important pathways involved in plant defenses jasmonic acid (JA) salicylic (SA). The crosstalk between these hormonal signaling seems fine-tune responses different stressors. this study, we characterized maize (Zea mays) under attack economically pests: bacterial pathogen causes Goss’s wilt leaf blight (Clavibacter michiganensis subsp. nebraskensis), chewing insect, fall armyworm (Spodoptera frugiperda). Our results indicate wilt-resistant when pretreated bacteria became more vulnerable subsequent by larvae. Furthermore, hormone analysis demonstrated antagonistic JA-Isoleucine (JA-Ile), biologically active form JA, SA contributed enhanced susceptibility herbivory. Collectively, our suggest may play a major role defense against study will improve understanding ability predict plant-induced an crop.
