Somatic embryogenetic receptor kinase TaSERL2 regulates heat stress tolerance in wheat by influencing TaBZR2 protein stability and transcriptional activity.
Article in Plant biotechnology journal, 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
Heat stress is a major factor limiting crop yield, a challenge intensified by climate change. Initial findings indicate that BES1/BZR1 may use heat shock to regulate plant thermal adaptability independently of BIN2-mediated brassinosteroid signalling, although the exact molecular mechanism remains unclear. In this study, we identified TaBZR2, a wheat gene whose expression showed a strong positive correlation with heat stress tolerance, based on transcriptome analysis of heat-tolerant wheat cultivars. Overexpression of TaBZR2 enhanced heat stress tolerance, while RNA interference of TaBZR2 reduced it. Further analysis revealed that TaBZR2 interacts with and is phosphorylated by wheat somatic embryogenesis receptor-like kinase 2 (TaSERL2). Overexpression of TaSERL2 reduced heat stress tolerance by promoting TaBZR2 degradation and inhibiting its regulation of wheat heat stress response genes. However, heat stress reduced the phosphorylation levels of both TaSERL2 and TaBZR2, lessening TaSERL2's inhibitory effect on TaBZR2 and enhancing the stability of TaBZR2. These results reveal that the TaSERL2-TaBZR2 module negatively regulates plant heat stress tolerance. This study expands the current model of heat stress responses and provides evidence for the role of BES1/BZR1 in heat stress regulation independent of brassinosteroid signalling.
