Development and optimization of in vitro shoot regeneration in Physalis peruviana using cotyledon explants.
Article in Journal, genetic engineering & biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
The genetic improvement of Physalis peruviana L. faces important challenges because it is a recalcitrant species, which limits its use in breeding and conservation programs. In the present research, the objective was to develop an effective regeneration protocol using cotyledon cultures. For this purpose, the effects of zeatin (ZT) and meta-topoline (mT) at concentrations of 0, 0.5, 1.0 and 2.0 mg/L and the effects of several auxins, including indolbutyric acid (IBA), indolacetic acid (IAA), naphthaleneacetic acid (NAA) and 2.4-dichlorophenoxyacetic acid (2.4-D), on morphogenetic responses were evaluated. A maximum regeneration of 62.5 % was achieved with the combination of 2 mg/L ZT, 2 mg/L mT, and 0.5-1 mg/L IBA. For root formation, the best results were obtained with the combination of 2 mg/L ZT, 2 mg/L mT, and 1 mg/L NAA, reaching a maximum rate of 87.5 %. In conclusion, specific combinations of cytokinins and auxins can overcome the resistance of P. peruviana to regeneration and provide a solid basis for biotechnological applications such as genetic transformation and germplasm conservation.
