Autophagy is induced during plant grafting to promote wound healing.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Grafting is an agricultural technique that joins tissues from different plants to obtain useful rootstock traits. However, cellular processes involved in joint tissue repair remain poorly understood. We analyzed Nicotiana benthamiana (Nb) and Arabidopsis thaliana (At) interfamily heterografting as a high-stress model and At homografting as a low-stress model. Transmission electron micrographs reveal the formation of autophagic structures in cells near the graft boundary over a long period in Nb/At interfamily grafts and in a short period of a few days in At homografts. Using a GFP-ATG8 marker line, the autophagosomes were observed in the cells near the graft boundary, especially on the scion side, where nutrient depletion occurred. Grafting of At autophagy-defective mutants decreases grafting success rates and post-grafting growth. NbATG5 knockdown suppresses graft establishment in Nb/At interfamily heterografts. Moreover, At autophagy-defective mutants show reduced callus formation directed to wounds under the nutrient-deficient conditions. These results suggest that autophagy is induced during grafting, promoting callus formation and contributing to tissue connectivity.
