Comparative physiological, antioxidant and proteomic investigation reveal robust response to cold stress in Digitalis purpurea L.
Article in Molecular biology reports, 2023. 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
background of the studyDigitalis purpurea (L) is an important medicinal plant growing at Alpine region of Himalayas and withstands low temperatures and harsh climatic conditions existing at high altitude. It serves as an ideal plant system to decipher the tolerance to cold stress (CS) in plants from high altitudes. METHODS AND
resultsTo understand the complexity of plant response to CS, we performed a comparative physiological and biochemical study complemented with proteomics in one-month-old D. purpurea grown at 25 °C (control) and 4 °C (CS). We observed an enhanced accumulation of different osmo-protectants (glycine betaine, soluble sugar and proline) and higher transcription (mRNA levels) of various antioxidant enzymes with an increased antioxidant enzyme activity in D. purpurea when exposed to CS. Furthermore, higher concentrations of non-enzymatic antioxidants (flavonoids, phenolics) was also associated with the response to CS. Differential proteomic analysis revealed the role of various proteins primarily involved in redox reactions, protein stabilization, quinone and sterol metabolism involved in CS response in D. purpurea..
conclusionOur results provide a framework for better understanding the physiological and molecular mechanism of CS response in D. purpurea at high altitudes.
