Color-dependent defense mechanisms of Quinoa (Chenopodium quinoa Willd.) against Spodoptera exigua: metabolomic and transcriptomic insights.

ABSTRACT:

Background

Quinoa (Chenopodium quinoa Willd.) exhibits a diverse and complex response to various organisms and environmental factors. The Spodoptera exigua elicits varying levels of damage in different crops. Secondary metabolites in quinoa induce defense mechanisms against S. exigua and play a key role in influencing its feeding preferences. Although the co-evolution of quinoa and S. exigua has been explored, the understanding of the interaction between these species remains limited. We aimed to evaluate the defense mechanisms of differently colored quinoa (red, white, yellow, and black) against S. exigua using metabolomics and transcriptome analyses. Metabolomic analysis was used to identify insect-resistant metabolites in four differently colored quinoa cultivars, whereas transc
