Identification of microRNAs involved in the Phosphate starvation response in Oil Palm (Elaeis guineensis Jacq.).
Article in Molecular biology reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPlant microRNA, often known as miRNA, is a novel form of gene expression regulator that is known to play a significant role in phosphate starvation. The identification of microRNAs involved in the response to phosphate starvation in oil palms is beneficial for breeding programs.
methodThe main nursery stage seedlings of two oil palm progenies were treated with three different fertiliser namely: complete fertiliser with urea, P2O5, K2O, and MgO based on the standard procedure as a control (C); fertiliser with urea, K2O, MgO without P2O5 (P0); and no fertiliser (F0) for 24 weeks. A total of six oil palm roots were subjected to RNA isolation, followed by miRNA sequencing using the Illumina HiSeq 4000 platform, and all reads were computationally analysed.
resultsIn total, 119 potential miRNAs related to 5,891 genes were identified. The P-specific miRNAs were assumed based on the miRNAs that identified without P fertilizer treatment, resulted of twenty miRNA sequences in the treatment comparison of (C vs P0) vs (C vs F0). Those 20 miRNA sequences were grouped into 9 families, namely EgmiR319; EgmiR399; EgmiR396; EgmiR172; EgmiR156; EgmiR157; miR5648; miR5645; and EgmiRNA_unidentified. Two miRNAs were selected for RT-qPCR validation, namely EgMir399 and EgMir172. Their expression pattern was similar with the RNA sequencing results and shown opposite expression pattern with their target genes, UBC E2 24 and APETALA2, respectively.
conclusionsThe nine micro RNA families was identified in oil palm root tissue at phosphate starvation.
