Comparison of maize brown-midrib isogenic lines by cellular UV-microspectrophotometry and comparative transcript profiling.
Article in Plant molecular biology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
The molecular mechanisms underlying cell wall digestibility in maize (Zea mays L.) have been studied in three sets of maize brown-midrib isogenic lines in the genetic background of inbreds 1332 (1332 and 1332 bm3), 5361 (5361 and 5361 bm3), and F2 (F2, F2 bm1, F2 bm2, and F2 bm3). Two complementary approaches, SSH (suppression subtractive hybridization) and microarray-based expression profiling, were used to isolate and identify candidate genes in isogenic lines for bm mutants. Metabolic pathway analysis revealed that transcriptional events caused by altering the expression of a single bm gene involve all metabolic and signaling pathways. 53 ESTs were differentially expressed in all three isogenic bm3 comparisons, whereas 32 ESTs were consistently differentially expressed in different bm isogenic lines in F2 background. About 70% ESTs isolated by SSH were not present on the unigene microarray, demonstrating the usefulness of the SSH procedure to identify genes related to cell wall digestibility. Together with lignin analysis by cellular UV-microspectrophotometry, expression profiling in isogenic bm lines proved to be useful to understand alterations at the sub-cellular and molecular level with respect to lignin composition. The down-regulation of COMT affected the expression of CCoAOMT genes and caused a reduced content both of G and S units in bm3 mutants.
