Genome-wide identification of high-affinity nitrate transporter 2 (NRT2) gene family under phytohormones and abiotic stresses in alfalfa (Medicago sativa).

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
The high-affinity nitrate transporter 2 (NRT2) protein plays an important role in nitrate uptake and transport in plants. In this study, the NRT2s gene family were systematically analyzed in alfalfa. We identified three MsNRT2 genes from the genomic database. They were named MsNRT2.1-2.3 based on their chromosomal location. The phylogenetic tree revealed that NRT2 proteins were categorized into two main subgroups, which were further confirmed by their gene structure and conserved motifs. Three MsNRT2 genes distributed on 2 chromosomes. Furthermore, we studied the expression patterns of MsNRT2 genes in six tissues based on RNA-sequencing data from the Short Read Archive (SRA) database of NCBI, and the results showed that MsNRT2 genes were widely expressed in six tissues. After leaves and roots were treated with drought, salt, abscisic acid (ABA) and salicylic acid (SA) for 0-48 h, and we used quantitative RT-PCR to analyze the expression levels of MsNRT2 genes and the results showed that most of the MsNRT2 genes responded to these stresses. However, there are specific genes that play a role under specific treatment conditions. This result provides a basis for further research on the target genes. In summary, MsNRT2s play an irreplaceable role in the growth, development and stress response of alfalfa, and this study provides valuable information and theoretical basis for future research on MsNRT2 function.
