| description | Plants employ sophisticated defense mechanisms, including releasing volatile
organic compounds, to defend against biotic and abiotic stresses. These
compounds play a crucial role in plant defense by attracting natural enemies
and facilitating communication between plants to activate defense mechanisms.
However, there has been no research on how exposure to these compounds
activates defense mechanisms in citrus plants. To elucidate the underlying
mechanisms governing citrus defensive activation, we conducted a molecular
analysis of the rootstock Citrange carrizo [a hybrid of Citrus sinensis × Poncirus
trifoliata] in response to defense activation by the volatile (Z)-3-hexenyl
propanoate [(Z)-3-HP], utilizing a groundbreaking transcriptomic analysis
involving the genomes of both parental species. Our results revealed
significant gene expression changes, notably the overexpression of genes
related to plant immunity, antioxidant activity, defense against herbivores, and
tolerance to abiotic stress. Significantly, P. trifoliata contributed most notably to
the hybrid’s gene expression profile in response to (Z)-3-HP. Additionally, plants
exposed to (Z)-3-HP repelled several citrus pests, attracted natural predators,
and led to diminished performance of two key citrus pests. Our study emphasizes
the complex molecular basis of volatile-triggered defenses in citrus and
highlights the potential of plant volatiles in pest control strategies. |
