Transcriptional regulation of genes involved in the pathways of biosynthesis and supply of methyl units in response to powdery mildew attack and abiotic stresses in wheat.

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
From a library of 3,000 expression sequence tags (ESTs), derived from the epidermis of a diploid wheat (Triticum monococcum) inoculated with Blumeria graminis f. sp. tritici (Bgt), we cloned 23 cDNAs representing 12 genes that are involved in the pathways of biosynthesis and supply of methyl units. We studied the transcription of these genes to investigate how the methyl units are generated and regulated in response to Bgt infection and abiotic stresses in wheat. Expression of 5, 10-methylene-tetrahydrofolate reductase, methionine synthase, S-adenosylmethionine synthetase, and S-adenosylhomocystein hydrolase transcripts were highly induced at an early stage of infection. This induction was specific to the epidermis and linked to host cell wall apposition (CWA) formation, suggesting that the pathways for generation of methyl units are transcriptionally activated for the host defense response. Levels of S-adenosylmethionine decarboxylase, caffeic acid 3-O-methyltransferase, 1-aminocyclopropane-1-carboxylate oxidase mRNA, but not phosphoethanolamine N-methyltransferase and nicotianamine synthase mRNA, were up-regulated after infection and showed similar expression patterns to genes involved in the pathways of generation of methyl units, revealing possible routes of methyl transfer towards polyamine, lignin and ethylene biosynthesis rather than glycine betaine and nicotianamine in response to Bgt attack. After imposing various abiotic stresses, genes involved in the pathways of generation and supply of methyl units were also up-regulated differentially, suggesting that the generation of sufficient methyl units at an early stage might be crucial to the mitigation of multiple stresses.
