Comparative study of gene expression and major proteins' function of laticifers in lignified and unlignified organs of mulberry.
Article in Planta, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
A laticifer is a cell involved in plant defense against biotic stresses such as herbivores and microorganisms; however, its gene expression is poorly understood. We compared protein accumulation and transcriptomes among laticifers of lignified and unlignified organs of mulberry (Morus alba), which has a non-articulated, branched type of laticifer. LA-a (equivalent to MLX56) and its homolog LA-b (insecticidal chitinase-like proteins containing two chitin-binding domains) were major proteins in laticifers of unlignified organs, and another protein (LA-c) was a major protein in laticifers of lignified organs. Purification, cDNA cloning, and bioassay of LA-c revealed that LA-c was an acidic class I chitinase having antifungal but not insecticidal activity. Comparative mRNA-Seq analysis using a GS-FLX revealed transcripts of other possible defense-related proteins. Jacalin-like lectin, galacturonase-inhibitor, and pathogenesis-related proteins were also abundant; however, the relative amounts differed among laticifers of lignified and unlignified organs. The results suggest a discontinuous laticifer network in planta and adaptation to different potential enemies among these organs.
