An ERF Gene DcERF3 of Dendrobium catenatum Improves Salt Tolerance in Arabidopsis.

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
The ethylene-responsive transcription factors (ERFs) perform pivotal regulatory functions in plant growth, development, and stress responses. Nonetheless, there is limited research on the functional characterization of ERFs in the medicinal orchid, Dendrobium catenatum. Here, we identified a salt-induced ERF gene DcERF3 from a D. catenatum cultivar Tiepi. DcERF3 comprises 186 amino acids and has a confirmed molecular weight of 21 kDa. It possesses a conserved AP2/ERF domain and displays a strong affiliation with the evolutionary lineage of other characterized ERFs. Analysis of expression patterns indicated that DcERF3 exhibits predominant expression in stems and roots, with considerably higher levels than in other tissues, and it demonstrated significant upregulation in response to treatments involving salt, ETH, PEG, and SA. The DcERF3-YFP protein localizes to the nucleus, and DcERF3 displays distinct transcriptional activation characteristics. Overexpressing DcERF3 led to an increased lateral root formation and enhanced tolerance to salt stress in Arabidopsis. Furthermore, the activities of antioxidant enzymes, along with the stress-responsive genes, were significantly induced in transgenic plants when subjected to salt stress. This study aims to investigate the function and role of DcERF3 in D. catenatum to establish a foundation for examining its involvement in lateral root formation and response to salt stress.
