Effectiveness of Trichoderma harzianum in mitigating Beet curly top Iran virus infection in tomato plants.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 investigates the potential of Trichoderma harzianum to mitigate the effects of Beet curly top Iran virus (BCTIV) on tomato plants. Tomato seedlings at the four-leaf stage were treated with a T. harzianum suspension and subsequently agroinoculated with a BCTIV infectious clone. The experiment included four treatments: mock plants (C), BCTIV-inoculated plants (V), Trichoderma-treated plants (T), and plants both infected with BCTIV and treated with Trichoderma (TV). Three weeks post-inoculation, symptom development and virus accumulation were assessed. At 45 days post-inoculation, root colonization by T. harzianum was confirmed. The disease severity index indicated a significant reduction in TV plants compared to V plants. Virus accumulation was also significantly lower in TV plants. Real-time PCR analysis showed increased expression of defense-related genes (HSP90, AGO2a, PR1) in TV plants, suggesting enhanced plant defense responses. Additionally, TV plants exhibited the highest fresh and dry weight among all groups. The presence of T. harzianum spores in the roots of TV plants confirmed successful colonization. These findings demonstrate that T. harzianum enhances tomato resistance to BCTIV by activating plant defense mechanisms, reducing disease severity and viral replication, promoting healthier growth and greater biomass in the treated tomato plants.
