Transcriptome analysis reveals regulatory mechanisms of different drought-tolerant Gleditsia sinensis seedlings under drought stress.
Article in BMC genomic data, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundGleditsia sinensis is a significant tree species from both ecological and economic perspectives. However, its growth is hampered by temporary droughts during the seedling stage, thereby impeding the development of the G. sinensis industry. Drought stress and rehydration of semi-annual potted seedlings using an artificial simulated water control method. RNA sequencing (RNA-seq) analyses were conducted on leaves collected from highly resistant (HR) and highly susceptible (HS) seedling families at five different stages during the process of drought stress and rehydration to investigate their gene expression patterns.
resultsThe differentially expressed genes (DEGs) were predominantly enriched in pathways related to "chloroplast" (GO:0009507), "photosynthesis" (GO:0015979), "plant hormone signal transduction" (map04075), "flavonoid biosynthesis" (map00941), "stress response", "response to reactive oxygen species (ROS)" (GO:0000302), "signal transduction" (GO:0007165) in G. sinensis HR and HS families exposed to mild and severe drought stress. Additionally, the pathways related to "plant hormone signal transduction" (map04075), and osmoregulation were also enriched. The difference in drought tolerance between the two families of G. sinensis may be associated with "transmembrane transporter activity" (GO:0022857), "stress response", "hormones and signal transduction" (GO:0007165), "cutin, suberine and wax biosynthesis" (map00073), "ribosome" (map03010), "photosynthesis" (map00195), "sugar metabolism", and others. An enrichment analysis of DEGs under severe drought stress suggests that the drought tolerance of both families may be related to "water-soluble vitamin metabolic process" (GO:0006767), "photosynthesis" (map00195), "plant hormone signal transduction" (map04075), "starch and sucrose metabolism" (map00500), and "galactose metabolism" (map00052). Osmoregulation-related genes such as delta-1-pyrroline-5-carboxylate synthase (P5CS), Amino acid permease (AAP), Amino acid permease 2 (AAP2) and Trehalose-phosphate synthase (TPS), as well as the antioxidant enzyme L-ascorbate peroxidase 6 (APX6), may be significant genes involved in drought tolerance in G. sinensis. Five genes were selected randomly to validate the RNA-seq results using quantitative real-time PCR (RT-qPCR) and they indicated that the transcriptome data were reliable.
conclusionsThe study presents information on the molecular regulation of the drought tolerance mechanism in G. sinensis and provides a reference for further research on the molecular mechanisms involved in drought tolerance breeding of G. sinensis.
