Identification and characterization of sulphotransferase (SOT) genes for tolerance against drought and heat in wheat and six related species.

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
backgroundSulphotransferase (SOT) enzyme (encoded by a conserved family of SOT genes) is involved in sulphonation of a variety of compounds, through transfer of a sulphuryl moiety from 3'phosphoadenosine- 5'phosphosulphate (PAPS) to a variety of secondary metabolites. The PAPS itself is derived from 3'adenosine-5'phosphosulphate (APS) that is formed after uptake of sulphate ions from the soil. The process provides tolerance against abiotic stresses like drought and heat in plants. Therefore, a knowledge of SOT genes in any crop may help in designing molecular breeding methods for improvement of tolerance for drought and heat.
methodsSequences of rice SOT genes and SOT domain (PF00685) of corresponding proteins were both used for identification of SOT genes in wheat and six related species (T. urartu, Ae. tauschii, T. turgidum, Z. mays, B. distachyon and Hordeum vulgare), although detailed analysis was conducted only in wheat. The wheat genes were mapped on individual chromosomes and also subjected to synteny and collinearity analysis. The proteins encoded by these genes were examined for the presence of a complete SOT domain using 'Conserved Domain Database' (CDD) search tool at NCBI.
resultsIn wheat, 107 TaSOT genes, ranging in length from 969 bp to 7636 bp, were identified and mapped onto individual chromosomes. SSRs (simple sequence repeats), microRNAs, long non-coding RNAs (lncRNAs) and their target sites were also identified in wheat SOT genes. SOT proteins were also studied in detail. An expression assay of TaSOT genes via wheat RNA-seq data suggested engagement of these genes in growth, development and responses to various hormones and biotic/abiotic stresses.
conclusionsThe results of the present study should help in further functional characterization of SOT genes in wheat and other related crops.
