Genomic survey and expression analysis of the CDPK genes in Liriodendron Chinense to explore their potential functions under multiple abiotic stresses.
Article in BMC genomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCalcium-dependent protein kinases (CDPKs) are key components of calcium signal transduction pathway, which play crucial roles in plant growth, development and abiotic stress response. The forest tree Liriodendron chinense possesses high ecological, ornamental, and economic value; however, abiotic stresses restrict its growth, reproductive capacity, and geographical distribution. The identification of the CDPK gene family in L. chinense, along with analyses of their structural and evolutionary relationships, tissue-specific expression patterns, will facilitate the elucidation of their functions in responding to abiotic stresses.
resultsA total of 21 CDPK genes were identified in the L. chinense genome and phylogenetically classified into four distinct groups. Amino acid sequences of most CDPKs contained four typical EF-hand structures. The cis-acting elements analysis of the promoter region showed a general representation of the ARE, MBS and LTR elements related to abiotic stress. RNA-seq analysis revealed that 6 h, 24 h, and 3 d post-abiotic stress were critical time points for the plant’s regulatory responses. RT-qPCR expression profiles demonstrated that the selected LcCDPKs exhibited differential expression across various tissues, and expression profiling suggested a collective trend of responsiveness to these stresses, with the most pronounced and sustained transcriptional changes often observed under heat stress, followed by cold and then drought. Subcellular localization assays indicated that LcCDPK5-GFP and LcCDPK10-GFP were localized to the nucleus and cell membrane, while LcCDPK5 was additionally localized to the cytoplasm.
conclusionsThis study systematically identified CDPKs in L. chinense, and indicates their potential roles in response to abiotic stress. This study provides important insights into the evolution and function of CDPKs in L. chinense.
