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

B-cell receptor-associated protein 31 (BAP31) is an endoplasmic reticulum (ER) transmembrane protein in humans that regulates protein trafficking, apoptosis, and inflammatory responses to maintain cellular homeostasis. However, its role in plants remains largely unknown. Here, we identified two tomato (Solanum lycopersicum) homologs, SlBAP31 and SlBAP31-LIKE, which are strongly induced by heat stress and function redundantly to stabilize photosystem II-light-harvesting complex II (PSII-LHCII) supercomplexes. Although localization to the ER or Golgi apparatus has been detected, both proteins are also present in chloroplasts, where they interact with SlTOC75, a core component of the chloroplast TOC-TIC translocon complex. Loss of either protein reduces the abundance of PSBW under heat stress. Among the two tomato PSBW isoforms, SlPSBW2 plays a predominant role in PSII-LHCII stability, and its accumulation depends in part on glycine 121 at the C terminus and interaction with SlBAP31/SlBAP31-LIKE. Collectively, our results reveal that ER/Golgi- and chloroplast periphery-localized SlBAP31 and SlBAP31-LIKE positively regulate tomato thermotolerance by mediating SlPSBW2 accumulation and stabilizing the PSII-LHCII supercomplex.
