Impact of Trichoderma, abscisic acid and polyamines on resistance tomato cultivars against M. incognita infection.
Article in Molecular biology reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
backgroundThe interaction of various treatments such as abscisic acid (ABA), polyamines (PS), and biological control with Trichoderma against Meloidogyne incognita was evaluated to assess their impact on pathological indices, growth metrics, and defense mechanisms in tomato cultivars.
methodsThe study assessed Meloidogyne incognita root tomato disease (number of galls and egg masses) and growth parameters (shoot, root system, and fruit weight) in two tomato cultivars (1077 and Dania 85), along with the activities of defense enzymes; peroxidase (POD), polyphenol oxidase (PPO) and expression of defense genes (POD, PPO and PR2). Specifically, the study evaluated abscisic acid (ABA; 10 µM), potassium silicate (5 g/L), and biological Trichoderma harzianum (10
resultsAmong the treatments applied, the 1077 cultivar demonstrated the highest resistance, exhibiting the lowest number of galls and egg masses. All treatments (ABA, PS, and Trichoderma) significantly increased growth parameters compared to the nematode-infected untreated control. Specifically, PS treatment showed the strongest enhancement in shoot fresh weight across both cultivars (1077 and Dania 85). Enzyme activities of PPO and POD, along with the gene expressions of POD, PPO and PR2, were elevated across all treatments. PS was the most effective treatment, followed by ABA and Trichoderma, significantly boosting both enzyme activities and gene expressions relative to the untreated control. The 1077 cultivar the resistant hybrid consistently outperformed Dania 85 in enzyme activities and gene expression.
conclusionsPS and ABA significantly enhanced growth (≤ 57.4%↑) and defense (≤ 3.3-fold↑), with 1077 exhibiting superior resistance (48-53%↓ pathology). This hybrid is already marketed as a resistant cultivar, underscoring the potential for integrated disease management strategies.
