Genome-wide identification and stress-responsive expression profiling of the TCP gene family in Cenchrus fungigraminus under drought and cold stress.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundTCP transcription factors play a crucial role in various biological processes, including plant growth, development, and response to abiotic stress. However, few related studies investigated the characteristics of TCP genes of Cenchrus and how it plays a role in abiotic stress responses.
resultsHere, we identified 40 CfuTCPs unevenly distributed across 13 chromosomes of Cenchrus fungigraminus and classified them into three subfamilies based on the conserved domain and phylogenetic analysis. Sequence analysis revealed that all CfuTCPs contain basic Helix-Loop-Helix conserved regions, and the majority of the CfuTCP genes were intronless. Twelve genes in the CIN subclade had potential miR319 target sites. Cis-acting element analysis showed that most CfuTCP genes contained many light-, phytohormone-, and developmental stress-responsive elements in their promoter regions. Furthermore, CfuTCPs play an important role in biological activities such as transcription regulation, regulation of biosynthetic processes, and metabolic processes, and were involved in plant circadian rhythms and environmental adaptation pathways. Notably, RNA-seq data showed that most CfuTCPs were involved in stress response under drought and cold treatments. Through RNA-seq analysis and qPCR validation, CfuTCP27/31 were found to play a positive regulatory role in drought stress, while CfuTCP06 plays a negative potentially.
conclusionsIn total, 40 CfuTCP genes were identified in C. fungigraminus. Functional predictions suggested the roles of CfuTCPs in modulating multiple C. fungigraminus physiological processes and metabolic pathways. The induced expression of CfuTCPs under drought and cold stress indicated their involvement in abiotic stress response in C. fungigraminus. These findings lay the groundwork for further research on TCP genes in C. fungigraminus.
