Genistein Mediates Beauveria bassiana-Induced Resistance Against Bemisia tabaci Reproduction in Tomato.
Article in Plant, cell & environment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Endophytic colonization by entomopathogenic fungi Beauveria bassiana enhances plant resistance to herbivores; however, the underlying molecular mechanisms, particularly those involving hormonal disruption of pests, remain poorly understood. This study examined whether root inoculation of tomato with B. bassiana suppresses whitefly Bemisia tabaci fitness via flavonoid modulation. Metabolomic profiling of leaf tissues showed a 3.5-fold accumulation of the isoflavonoid genistein in B. bassiana-inoculated plants. KEGG enrichment analysis indicated significant upregulation of the isoflavonoid biosynthesis pathway. Virus-induced gene silencing of SlHIDH (2-hydroxyisoflavanone dehydratase), a key gene in genistein biosynthesis, reversed the fungal-mediated protection: it increased whitefly ovariole number by 20.5% and oviposition by 23.5% compared with the control. Correspondingly, B. bassiana inoculation downregulated seven whitefly reproduction-related genes (BtPLA, BtJHAMT, BtFPPS, BtPER, BtSPN, BtELOVL, BtAPN), whereas SlHIDH silencing abolished this effect and led to their upregulation. In artificial feeding assays, dietary genistein reduced oviposition by 32.9% and ovariole formation by 19.6%. Our findings demonstrate that B. bassiana elevates genistein levels in tomato, which impairs whitefly ovarian development and reproduction via endocrine disruption. These results reveal a tripartite interaction in which EPF enhances plant defense through specific secondary metabolites that target insect reproductive physiology, providing molecular insights for improving biocontrol strategies against sap-sucking pests.
