Transcriptome responses in wheat roots to colonization by the arbuscular mycorrhizal fungus Rhizophagus irregularis.

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 influence of arbuscular mycorrhizal (AM) colonization on the expression of genes in the roots of wheat (Triticum aestivum L.) at the transcriptome level is largely unknown. A pot experiment was established to study the responses of the transcriptome profile in the roots of wheat to colonization by the AM fungus Rhizophagus irregularis using high through-put sequencing methods. The results indicated that the expression of 11,746 genes was regulated by AM colonization, and 64.7% of them were up-regulated genes. 1106 genes were only expressed in roots colonized by AM fungi, and 108 genes were only expressed in non-mycorrhizal roots. The differentially expressed genes (DEGs) were primarily distributed on the 2B, 3B, 2A, 2D, and 5B chromosomes of wheat. The DEGs (including both up- and down- regulated) mainly located on membranes, and functioned in nucleotide binding and transferase activity during cellular protein modification and biosynthetic processes. The data revealed that AM colonization up-regulated genes involved in the phenylpropanoid biosynthesis pathway and transcription factors which play vital roles in protecting plants from biotic or abiotic stresses. A number of key genes involved in molecular signal biosynthesis and recognition, epidermal cell colonization and arbuscule formation, carbon and nutrients exchange during AM symbiosis were found. All the ammonium transporter (AMT), iron-phytosiderophore transporter, boron, zinc, and magnesium transporter genes found in our study were up-regulated DEGs. One new AM-specific induced AMT and three new AM-specific induced nitrate transporter (NRT) genes were found in the roots of wheat colonized by AM fungi, even though a negative growth response of wheat to AM colonization occurred. The present study provided new information which is important for understanding the mechanisms behind the development and function of the symbiosis between wheat and AM fungi.
