“…Studies have shown that lignin and tannins are more effective against specialists, but alkaloids or flavonoids are considered primarily effective against generalists, indicating that condensed tannins are not the only indicator for poplar resistance to pests (Wang et al, 2012). P. versicolora is considered a generalist because it feeds on many plant species, such as poplar, willow, mulberry, maize and soybean (Thiel et al, 2020; Xie et al, 2020). Recent studies have found that flavonoids and anthocyanins are key secondary metabolites involved in plant responses to abiotic and biotic stresses (Ahmed et al, 2021; Wang, Li, et al, 2018b).…”

Dioecious plants have evolved effective defense strategies to deal with various biotic and abiotic stresses. However, little is known regarding sexual differences in their defense against herbivores. In this study, we investigated the mechanism of systemic defense responses in male and female Populus cathayana attacked by Plagiodera versicolora Laicharting. The results revealed that P. cathayana exhibits sexually differential responses to a defoliator. The percentage of damaged leaf area was greater in males than in females. Furthermore, the observed saccharide changes imply that males and females exhibit different response times to defoliators. The contents of flavonoids and anthocyanins were significantly increased in both sexes but were higher in females. Specifically, the jasmonic acid (JA) pathway plays an important role. Expression of pest‐related genes further revealed that hormones induce changes in downstream genes and metabolites, and upregulation of JA ZIM‐domain (JAZ) and CORONATINE INSENSITIVE 1 (COI1) was more significant in females. In the undamaged adjacent leaves, metabolite and gene changes displayed similar patterns to the damaged local leaves, but levels of JA, JAZ1, and COI1 were higher in females. Therefore, our data confirmed that plants initiate the JA pathway to defend against herbivores, that there is systematic signal transduction, and that this ability is stronger in females than in males. This study provides new insights into the resistance of dioecious plants to herbivory and adds a new theoretical basis for the systemic signal transduction of plants in response to biotic stress.

Plagiodera versicolora (Coleoptera: Chrysomelidae) is one of the most destructive pests of the Salicaceae worldwide, which has established complex interactions with surrounding organisms. Uncovering the molecular mechanisms of some antagonistic interactions would facilitate the development of environmentally friendly pest insect management strategies. Suitable reference genes are essential for reliable qPCR and gene expression analysis in molecular studies; however, a comprehensive assessment of reference genes in P. versicolora is still lacking. In this study, the stability of seven housekeeping genes (including Actin, EF1A, α-tubulin, RPL13a, RPS18, RPL8 and UBC) was investigated under both biotic (developmental stages, tissues, sex and pathogen treatment) and abiotic (RNA interference treatment, temperature treatment) conditions. The geNorm, NormFinder, BestKeeper, and ΔCt programs were used to analyze gene expression data. The RefFinder synthesis analysis was applied to suggest a handful of appropriate reference genes for each experimental condition. RPS18 and EF1A were the most reliable reference genes in different development stages; RPS18 and RPL8 were most stable in female and male adults, different tissues, different temperatures, and pathogen treatment; α-tubulin and RPL13a were most stable after dietary RNAi treatment. The research provides a strong basis for future research into the molecular biology of P. versicolora.
