Identification and differential expression analysis of anthocyanin biosynthetic genes in root-skin color variants of radish (Raphanus sativus L.).
Article in Genes & genomics, 2020. 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
backgroundTaproot skin color is a major trait for assessing the commercial and nutritional quality of radish, and red-skinned radish is confirmed to improve consumer's interest and health. However, little is known about the molecular mechanisms responsible for controlling the formation of red-skinned radish.
objectiveThis study aimed to identify the differentially expressed anthocyanin biosynthetic genes between red- and white-skinned radishes and understand the molecular regulatory mechanism underlying red-skinned radish formation.
methodsBased on the published complete genome sequence of radish, the digital gene expression profiles of Yangzhouyuanbai (YB, white-skinned) and Sading (SD, red-skinned) were analyzed using Illumina sequencing.
resultsA total of 3666 DEGs were identified in SD compared with YB. Interestingly, 46 genes encoded enzymes related to anthocyanin biosynthesis and 241 genes encoded transcription factors were identified. KEGG pathway analysis showed that the formation of red-skinned radish was mainly controlled by pelargonidin-derived anthocyanin biosynthetic pathway genes. This process included the upregulation of PAL, C4H, 4CL, CHS, CHI, F3H, DFR, LDOX, and UGT enzymes in SD. CHS genes were specifically expressed in SD, and it might be the key point for red pigment accumulation in red-skinned radish. Furthermore, MYB1/2/75, bHLH (TT8), and WD 40 showed higher expression in SD than in YB. Meanwhile, the corresponding low-abundance anthocyanin biosynthesis enzymes and upregulation of MYB4 might be the factors influencing the formation of white-skinned radish.
conclusionThese findings provide new insights into the molecular mechanisms and regulatory network of anthocyanin biosynthesis in red-skinned radish.
