Regulation of jasmonic acid signalling in tomato cold stress response: Insights into the MYB15-LOXD and MYB15-MYC2-LOXD regulatory modules.

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
Cold stress significantly affects the growth and productivity of tomatoes. Despite the known involvement of jasmonate (JA) in cold stress responses, the underlying mechanism remains to be elucidated. Here, we observed that JA peaked 24 h after cold treatment. The expression of the SlLOXD gene, a key player in JA biosynthesis, also peaked at 24 h of cold exposure, and mutation in SlLOXD reduced JA content and cold tolerance. Downstream of JA signalling, the transcription factor SlMYC2 was implicated in enhancing cold resistance by directly binding to the SlCBF1/2 promoters. Furthermore, the SlMYC2-silenced plants and mutants exhibited increased sensitivity to cold damage. Additionally, SlMYB15 directly bound to the SlLOXD and SlMYC2 promoters. Within 6 h of cold stress, SlMYB15 activated SlLOXD expression while repressing SlMYC2 expression. Between 6 and 24 h, the expression level of SlMYB15 decreased, thereby alleviating the repression of SlMYC2 expression. SlMYC2 further enhanced JA signalling through the transcriptional activation of SlLOXD, thus improving cold tolerance in tomato plants. These findings provide valuable insights into the dynamic regulation of the SlLOXD-SlMYC2 -CBF1/2 module by SlMYB15 and its critical role in tomato cold stress responses.
