Identification and expression profiling of DNA methyltransferases during development and stress conditions in Solanaceae.
Article in Functional & integrative genomics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
DNA methyltransferase (DMTase) enzymes contribute to plant development and stress responses by de novo establishment and subsequent maintenance of DNA methylation during replication. However, the molecular mechanism underlying this activity remains obscure, especially in crop species. Using DMTase homolog complement in six Solanaceae species, we demonstrated here that their number remained conserved in Solanum lineage, whereas it was expanded in both pepper and Nicotiana benthamiana. Non-synonymous vs synonymous (Ka/Ks) substitution ratio revealed that most of the Solanaceous DMTase homologs undergo purifying selection. The genomic sequences of tomato DMT homologs in its wild relative, Solanum pennellii, remained highly conserved in their exons and methyltransferase domains. Structure analysis further revealed highly similar folding of DMTase homologs and conservation in the residues participating in protein-protein interaction in Solanum lineage, whereas a considerable diversification was observed of pepper homologs. Transcript profiling of DMTases highlighted both similar and distinct expression patterns of tomato homologs in other species during fruit development and stress responses. Overall, our analysis provides a strong basis for in-depth exploration of both conserved as well as distinct functions of tomato DMTase homologs in other economically important Solanaceae species.
