1 · What the graph read from it

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.

2 · The registry

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

Tomato (Solanum lycopersicum L.) is one of the most widely cultivated vegetable crops globally. Still, its productivity is significantly constrained by tomato leaf curl virus (ToLCV), a devastating begomovirus transmitted by whiteflies. This study examined the diversity and plant growth-promoting potential of culturable endophytes associated with tomato cultivars differing in resistance to tomato leaf curl virus (ToLCV). A total of 59 fungal and bacterial endophytes were isolated. Resistant cultivars (Nandi, Sankranthi, and Vybhav) harboured more diverse and compositionally distinct communities than the susceptible cultivar Arka Vikas, as indicated by Shannon, Simpson, and Chao-1 indices and multivariate analyses. Several isolates, particularly from the genera Xylaria, Fusarium, Arcopilus, Epicoccum, Bacillus, Pseudomonas, Stutzerimonas, and Paenibacillus, displayed strong nutrient-solubilizing traits in vitro, highlighting their potential as plant growth-promoting candidates. Eleven promising isolates were further evaluated on the susceptible cultivar Arka Vikas. At 30 days after sowing, Epicoccum nigrum and Bacillus subtilis significantly increased seedling height, biomass, and leaf number relative to the control. Overall, the study reveals that resistant cultivars are associated with greater culturable endophyte diversity and identifies several isolates with strong potential for promoting plant growth. Future research should assess the antiviral potential of these endophytes under ToLCV challenge and employ metagenomic studies to elucidate their functional roles in enhancing plant health.
