Genome-wide analysis of the rice PPR gene family and their expression profiles under different stress treatments.
Article in BMC genomics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 72 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
backgroundPentatricopeptide-repeat proteins (PPRs) are characterized by tandem arrays of a degenerate 35-amino-acid (PPR motifs), which can bind RNA strands and participate in post-transcription. PPR proteins family is one of the largest families in land plants and play important roles in organelle RNA metabolism and plant development. However, the functions of PPR genes involved in biotic and abiotic stresses of rice (Oryza sativa L.) remain largely unknown.
resultsIn the present study, a comprehensive genome-wide analysis of PPR genes was performed. A total of 491 PPR genes were found in the rice genome, of which 246 PPR genes belong to the P subfamily, and 245 genes belong to the PLS subfamily. Gene structure analysis showed that most PPR genes lack intron. Chromosomal location analysis indicated that PPR genes were widely distributed in all 12 rice chromosomes. Phylogenetic relationship analysis revealed the distinct difference between the P and PLS subfamilies. Many PPR proteins are predicted to target chloroplasts or mitochondria, and a PPR protein (LOC_Os10g34310) was verified to localize in mitochondria. Furthermore, three PPR genes (LOC_Os03g17634,LOC_Os07g40820,LOC_Os04g51350) were verified as corresponding miRNA targets. The expression pattern analysis showed that many PPR genes could be induced under biotic and abiotic stresses. Finally, seven PPR genes were confirmed with their expression patterns under salinity or drought stress.
conclusionsWe found 491 PPR genes in the rice genome, and our genes structure analysis and syntenic analysis indicated that PPR genes might be derived from amplification by retro-transposition. The expression pattern present here suggested that PPR proteins have crucial roles in response to different abiotic stresses in rice. Taken together, our study provides a comprehensive analysis of the PPR gene family and will facilitate further studies on their roles in rice growth and development.
