The unique age-dependent infestation pattern of A. induta\u2014with minimal damage to young tea plants but infestation rates reaching 20% in 30-year-old trees and nearly 100% in ancient tea trees\u2014necessitated field sampling from naturally infested old tea plantations rather than controlled laboratory conditions. By integrating rhizosphere microbiomics, transcriptomics, and multi-omics modeling, this study characterized the defensive regulatory networks of 30-year-old Shuixian tea cultivars under A. induta infestation. Rhizosphere microbiome analysis revealed that herbivore attack significantly reshaped the microbial community structure, reducing bacterial diversity and simplifying co-occurrence network complexity. Transcriptomic and metabolomic profiling demonstrated a precise source\u2013sink defense allocation between host tissues. In leaves acting as the photosynthetic source, metabolic reprogramming was dominated by the systematic accumulation of soluble sugars and sugar acids for systemic energy reallocation. Concurrently, the roots acting as the metabolic sink vigorously activated the jasmonic acid (JA) signaling cascade and upregulated genes enriched in phenylpropanoid biosynthesis and alpha-linolenic acid metabolism. This molecular activation drove the substantial de novo synthesis of defensive phenolic acids, while downregulating growth-related flavonoids. Integrated network modeling further highlighted the phenylpropanoid pathway as the central regulatory node coupling transcript\u2013metabolite fluctuations. This study constructs an integrated soil microbiome\u2013root\u2013leaf defense network, providing novel mechanistic insights into plant\u2013borer interactions and a valuable foundation for future insect-resistant breeding programs in the tea industry.<\/jats:p>","DOI":"10.3390\/insects17090911","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T12:41:18Z","timestamp":1788266478000},"page":"911","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Foliar and Root Dynamic Analyses Reveal a Coordinated Defense Regulatory Network Against Aeolesthes induta Infestation in Tea Plants"],"prefix":"10.3390","volume":"17","author":[{"given":"Chengcong","family":"Lu","sequence":"first","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Jialin","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Tourism, Xinyang Vocational and Technical College, Xinyang 464000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Ke","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Xuanyi","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Xi","family":"Du","sequence":"additional","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Fajie","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3766-3783","authenticated-orcid":false,"given":"Pumo","family":"Cai","sequence":"additional","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"validation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"conceptualization","vocabulary":"credit"}]},{"given":"Yongcong","family":"Hong","sequence":"additional","affiliation":[{"name":"College of Tea and Food Science, Wuyi University, Wuyishan 354300, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1038\/s41438-019-0225-4","article-title":"Tea plant genomics: Achievements, challenges and perspectives","volume":"7","author":"Xia","year":"2020","journal-title":"Hortic.
