Natural variation of CsUGT71A60 determines growth and cold tolerance via regulating cytokinin glycosylation in Camellia sinensis.
Article in Plant biotechnology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Cold stress severely limits tea plant (Camellia sinensis) productivity, yet the molecular mechanisms underlying cold adaptation remain elusive. Here, we identified a cold-inducible glycosyltransferase, CsUGT71A60, through integrative genome-wide association studies (GWAS) and proteomic profiling. Natural variation in CsUGT71A60 was strongly associated with cold tolerance, as evidenced by linkage disequilibrium analysis of flanking SNPs. Functional characterization revealed that CsUGT71A60 specifically catalyses the glycosylation of cis-zeatin to form cis-zeatin 9-O-glucoside in vitro and in vivo. Overexpression of CsUGT71A60 in Arabidopsis enhanced cold tolerance and agronomic traits, including germination rate, tiller number and seed weight, while delaying flowering. Transient silencing of CsUGT71A60 in tea plants disrupted cis-zeatin homoeostasis, impairing antioxidant defences and osmotic regulation under cold stress. Mechanistically, the transcription factor ARR (TEA021099) directly binds to CRM elements in the CsUGT71A60 promoter, activating its expression to fine-tune cytokinin signalling. This study unveils a dual-function glycosyltransferase that orchestrates stress tolerance and developmental plasticity, offering a strategic target for breeding climate-tolerance crops without yield penalties.
