Genome-wide identification and expression analysis of Ubiquitin-specific protease gene family in maize (Zea mays L.).
Article in BMC plant biology, 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
backgroundUbiquitin-specific proteases (UBPs) are a large family of deubiquitinating enzymes (DUBs). They are widespread in plants and are critical for plant growth, development, and response to external stresses. However, there are few studies on the functional characteristics of the UBP gene family in the important staple crop, maize (Zea mays L.).
resultsIn this study, we performed a bioinformatic analysis of the entire maize genome and identified 45 UBP genes. Phylogenetic analysis indicated that 45 ZmUBP genes can be divided into 15 subfamilies. Analysis of evolutionary patterns and divergence levels indicated that ZmUBP genes were present before the isolation of dicotyledons, were highly conserved and subjected to purifying selection during evolution. Most ZmUBP genes exhibited different expression levels in different tissues and developmental stages. Based on transcriptome data and promoter element analysis, we selected eight ZmUBP genes whose promoters contained a large number of plant hormones and stress response elements and were up-regulated under different abiotic stresses for RT-qPCR analysis, results showed that these genes responded to abiotic stresses and phytohormones to varying degrees, indicating that they play important roles in plant growth and stress response.
conclusionsIn this study, the structure, location and evolutionary relationship of maize UBP gene family members were analyzed for the first time, and the ZmUBP genes that may be involved in stress response and plant growth were identified by combining promoter element analysis, transcriptome data and RT-qPCR analysis. This study informs research on the involvement of maize deubiquitination in stress response.
