Study on the interaction preference between CYCD subclass and CDK family members at the poplar genome level.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Cyclin-dependent kinases (CDKs) control the progression of the cell cycle. D-type cyclin (CYCD) is generally believed to form a complex with CDK and control the G1/S transition. In plants, CYCD and CDK gene families can be divided into 6 (D1-D7) and 7 (CDKA-CDKG) subclasses, respectively. Different subclasses in the CYCD and CDK families have different numbers, structures and functions. In some heterologous woody plants, the functions of these subclass family members remain unclear. In this study, 43 CYCD and 27 CDK gene family members were identified in the allodiploid Populus tomentosa Carr. Phylogenetic analysis suggested that these CYCDs and CDKs were divided into 6 and 7 subclasses, respectively, which were the same as other species. The analysis of protein properties, gene structure, motifs, domains, cis-acting elements and tissue-specific expression of all members of these CYCDs and CDKs showed that the differences between members of different subclasses varied widely, but members of the same subclass especially in the CDK gene family were very similar. These findings also demonstrated a strong correlation between CYCD and CDK gene family members in response to hormones and specific expression. The collinear analysis of P. tomentosa, Populus trichocarpa and Arabidopsis thaliana showed that the expansion patterns of CYCD and CDK gene families were predominantly whole genome duplications (WGD). The protein interaction prediction results of different subclasses of CYCD and CDKs showed that the interaction between different subclasses of CYCD and CDKs was significantly different. Our previous study found that transgenic PtoCYCD2;1 and PtoCYCD3;3 poplars exhibited opposite phenotypes. Y2H and BIFC results showed that the interaction between PtoCYCD2;1 and PtoCYCD3;3 was significantly different with CDKs. This finding might suggest that the functional differences of different CYCD subclasses in plant growth and development were closely related to the different interactions between CYCD and CDK. Our results provide a good idea and direction for the functional study of CYCD and CDK proteins in woody plants.
