Physiological, biochemical, and transcriptomic analyses reveal potential candidate genes of Platostoma palustre in response to salt stress.

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
backgroundSalt stress poses a genuine threat to plants, impeding their growth, development, and yields. Platostoma palustre (Blume) A.J.Paton (P. palustre) is an important medicinal plant in tropical and subtropical regions; however, the molecular mechanisms underlying P. palustre response to salt stress remain poorly understood. To better understand the molecular response of P. palustre plants to salt stress, we employed an integrated approach based on physiological, biochemical, and transcriptomic analyses.
resultsIn this study, salt stress significantly restrained the growth of P. palustre and led to the accumulation of antioxidant enzymes (SOD, POD, and CAT). Besides, the chlorophyll content significantly decreased with the increase in NaCl concentration. Transcriptomic analysis revealed 8,679 differentially expressed genes (DEGs) (4,334 were up-regulated and 4,363 were down-regulated) between control (CK) and salt stress (150 mM NaCl). KEGG enrichment analysis showed that these DEGs were significantly enriched in "plant hormone signal transduction", "MAPK signaling pathway-plant", "photosynthesis - antenna proteins", "starch and sucrose metabolism", etc. Among the DEGs, 409 DEGs were identified as transcription factors (TFs), belonging to 25 families including MYB_superfamily, AP2/ERF, C2C2, bHLH, NAC, WRKY, and so on. In KEGG enrichment analysis of the identified TFs, 13 showed significant enrichment in "plant hormone signal transduction". Notably, EIN3 (TRINITY_DN3357_c1_g2) and ERF1 (TRINITY_DN8842_c0_g1) involved in the ethylene (ETH) signaling were suggested potential candidates for salt stress response in P. palustre.
conclusionsThis study unravels key salt-responsive genes in P. palustre, facilitating the development of salinity-resistance varieties.
