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

key messageCsPRR7 acts as a negative regulator of cold tolerance in tea plants via a CBF-dependent pathway. Low temperatures have caused severe damage to the growth and development of tea plants, directly impacting the quality and profitability of spring tea. Circadian clock plays an important role in sensing external environmental signals such as light and temperature, predicting daily environmental changes, and ensuring the rhythms of plant metabolism, physiology, and development. The PSEUDO RESPONSE REGULATOR (PRR) genes, key components of the circadian clock, play a vital role in plant adaptation to diurnal temperature changes. However, the specific role of the CsPRRs in tea plants in response to low-temperature stress, as well as the molecular regulatory mechanisms underlying this response, remain unclear. In this study, we characterized CsPRR7, a key component of the tea plant circadian oscillator, to explore its potential role in cold stress responses. The expression of CsPRR7 exhibits a distinct circadian rhythm. Furthermore, CsPRR7 was suppressed by low temperatures, and its rhythmic expression was significantly disrupted by cold stress treatment. Transient silencing of CsPRR7 enhanced cold tolerance in tea leaves, while its overexpression led to decreased cold tolerance. The yeast one-hybrid (Y1H) and dual-luciferase assays demonstrated that CsPRR7 inhibits the transcription of CsCBF3, a member of the C-repeat (CRT)/dehydration-responsive element (DRE)-binding factor (CBF) family, by directly binding to its promoter region. These results reveal that CsPRR7 acts as a negative regulator of cold tolerance in tea plants via a CBF-dependent pathway.
