Genome-wide identification and expression analysis of the ferritin family in sweetpotato and its two diploid relatives.

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
Ferritin (FER), a type of iron-storing proteins, play an essential role in iron storage and in protection against oxidative stress. However, there is limited detailed information regarding FERs in sweetpotato. In this study, a total of 17 putative FER genes, 7, 5 and 5 FERs in sweetpotato (I. batatas, 2n = 6x = 90) and its two diploid relatives I. trifida (2n = 2x = 30) and I. triloba (2n = 2x = 30), located on chromosomes were identified. Phylogenetic analysis revealed that these genes are divided into two different groups. Promoter analysis revealed that IbFER promoters contained a number of abiotic/biotic stress-responsive elements, hormone-responsive element, and iron-dependent regulatory sequence. The structural motif analysis of FER proteins showed that Euk_Ferritin domain was identified near the C-terminus and the structures were relatively conserved in sweetpotato and its two diploid relatives. Transcriptome and RT-qPCR analysis demonstrated that the expression of FERs were detected in different tissues and showed tissue specificity, and they responded to abiotic stresses, such as drought, salt and Fe deficiency. Our results provide a theoretical basis for future genetic research, development of breeding strategies against abiotic stresses and food enrichment with iron in sweetpotato.
