Role of Glycosyltransferases in Pollen Wall Primexine Formation and Exine Patterning.
Article in Plant physiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 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 pollen cell wall is important for protection of male sperm from physical stresses and consists of an inner gametophyte-derived intine layer and a sporophyte-derived exine layer. The polymeric constituents of the robust exine are termed sporopollenin. The mechanisms by which sporopollenin is anchored onto microspores and polymerized in specific patterns are unknown, but the primexine, a transient cell wall matrix formed on the surface of microspores at the late tetrad stage, is hypothesized to play a key role. Arabidopsis (Arabidopsis thaliana) spongy (spg) and uneven pattern of exine (upex) mutants exhibit defective and irregular exine patterns. SPG2 (synonymous with IRREGULAR XYLEM9-LIKE [IRX9L]) encodes a family GT43 glycosyltransferase involved in xylan backbone biosynthesis, while UPEX1 encodes a family GT31 glycosyltransferase likely involved in galactosylation of arabinogalactan proteins. Imaging of developing irx9l microspores showed that the earliest detectable defect was in primexine formation. Furthermore, wild-type microspores contained primexine-localized epitopes indicative of the presence of xylan, but these were absent in irx9l These data, together with the spg phenotype of a mutant in IRX14L, which also plays a role in xylan backbone elongation, indicate the presence of xylan in pollen wall primexine, which plays a role in exine patterning on the microspore surface. We observed an aberrant primexine and irregular patterns of incipient sporopollenin deposition in upex1, suggesting that primexine-localized arabinogalactan proteins could play roles in sporopollenin adhesion and patterning early in microspore wall development. Our data provide new insights into the biochemical and functional properties of the primexine component of the microspore cell wall.
