Accumulation of phytoalexins and alteration in plant hormone profiles in rice leaves following sap sucking by the brown planthopper and green rice leafhopper.

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
This study investigated the accumulation of cultivar-specific phytoalexins in rice-abietoryzins and oryzalactone-as well as known phytoalexins-momilactone A, phytocassane A, and oryzalexins A and S-in response to sap sucking by the brown planthopper (BPH) and the green rice leafhopper (GRL). The analysis revealed that BPH feeding induced abietoryzin accumulation in a cultivar known to accumulate these phytoalexins following fungal infection. Additionally, oryzalactone and oryzalexin S accumulated after insect attack in specific cultivars, unlike oryzalexin A. Plant hormone profiling revealed distinct associations: momilactone A accumulation was strongly correlated with salicylic acid (SA); phytocassane A with jasmonic acid, jasmonic acid-isoleucine, isopentenyladenine, and abscisic acid (ABA); and oryzalactone/oryzalexin S with both SA and ABA. These findings suggest that distinct signaling pathways regulate the induction of specific phytoalexins. The analysis of phenolic metabolites showed only minor changes in response to insect feeding. The findings highlight the broad inducibility of phytoalexins in rice and reveal the complex hormonal regulation underlying their biosynthesis during herbivore attack.
