Effects of Air Temperature on Transient Expression of Influenza Hemagglutinin in Nicotiana benthamiana: Analysis of Transgene Transcription and Plant Stress Responses.
Article in Biotechnology and bioengineering, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Postinfiltration air temperature is known to affect the accumulation of recombinant protein in Agrobacterium-mediated transient expression in Nicotiana benthamiana plants, including the number of days needed to reach maximum content and the rate of reduction thereafter. This study aimed to clarify whether the transcript levels of the transgenes and those of plant stress response markers (i.e., hypersensitive response and endoplasmic reticulum [ER] stress) could be primary determinants of the accumulation of recombinant influenza hemagglutinin (HA) at 21 or 26°C. We found no correlation between the transgene expression levels (HA, RdRP, and MP) and the number of days needed to reach the maximum HA protein content at both temperatures. Regardless of the accumulation compartment, HA protein content peaked earlier at 26°C than at 21°C. The rapid reduction of HA content after reaching the maximum, observed only in the ER at 26°C, correlated with severe necrosis and high transcript levels of two representative ER stress markers, bZIP60 and BiP. This correlation suggests that high postinfiltration air temperature affects HA accumulation primarily through ER stress, a key factor in the rapid reduction of HA content after the peak.
