Differential expression of phenylpropanoid and related genes in brown-midrib bm1, bm2, bm3, and bm4 young near-isogenic maize plants.

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 expression of phenylpropanoid and related genes was investigated in bm1, bm2, bm3, and bm4 near-isogenic maize plants at the 4-5 leaf stage using a gene-specific cell wall macro-array. The bm3 mutant, which is mutated in the caffeic acid O-methyltransferase (COMT) gene, exhibited the lowest number of differentially expressed genes. Although no other phenylpropanoid gene had an altered expression, two distinct OMT and two cytochrome P450 genes were overexpressed suggesting the activation of alternative hydroxylation/methylation pathways. The bm1 mutant had the highest number of differentially expressed genes, all of which were under-expressed. Bm1 mutant plants were affected not only in cinnamyl alcohol dehydrogenase (bm1 related CAD) gene expression as expected, but also in the expression of other CAD/SAD gene family members and several regulatory genes including MYB, ARGONAUTE and HDZip. As originally believed, the bm1 mutation could be localized at the CAD locus, but more probably in a gene that regulates the expression of the CAD gene family. The profile of under-expressed genes in the bm2 mutant is nearly similar to that of bm1. These genes fell under several functional categories including phenylpropanoid metabolism, transport and trafficking, transcription factors and regulatory genes. As the bm2 mutant exhibited a lower guaiacyl (G) unit lignin content, the bm2 mutation could affect a regulatory gene involved, perhaps indirectly, in the regulation, conjugation or transport of coniferaldehyde, or the establishment of G-rich maize tissues. The pattern of gene expression in bm4 plants, characterized by the over-expression of phenylpropanoid and methylation genes, suggests that the bm4 mutation likely also affects a gene involved in the regulation of lignification.
