Striga hermonthica induces lignin deposition at the root tip to facilitate prehaustorium formation and obligate parasitism.
Article in Plant communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Striga hermonthica, an obligate parasitic plant that causes severe agricultural damage, recognizes its hosts by sensing haustorium-inducing factors (HIFs). Perception of HIFs induces the rapid transformation of S. hermonthica radicles into prehaustoria, structures that enable host invasion and mature into haustoria. HIFs consist of various aromatic compounds, including quinones, lignin monomers, and flavonoids. However, the downstream molecular pathways that orchestrate these developmental events are largely unknown. Here, we report that S. hermonthica root-tip cells rapidly deposit lignin, a major cell wall component, in response to HIFs. In addition to enhancing lignin levels, HIFs strongly induce genes involved in lignin monomer biosynthesis and polymerization, including several respiratory burst oxidase homologs (RBOHs) and class III peroxidases. Disruption of lignin monomer biosynthesis compromises prehaustorium formation, whereas HIF-induced class III peroxidases facilitate the process by promoting lignification. Our study demonstrates that cell wall lignification is a converged cellular process downstream of various HIFs that guides root meristematic cells in prehaustorium development.
