1 · What the graph read from it

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.

2 · The registry

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

backgroundLeaf color mutants are ideal materials to study pigment metabolism and photosynthesis. Leaf color variations are mainly affected by chlorophylls (Chls) and carotenoid contents and chloroplast development in higher plants. However, the regulation of chlorophyll metabolism remains poorly understood in many plant species. The chloroplast signal-recognition particle system is responsible for the insertion of the light-harvesting chlorophyll a/b proteins (LHCPs) to thylakoid membranes, which controls the chloroplast development as well as the regulation of Chls biosynthesis post-translationally in higher plants.

resultsIn this study, the yellow leaf cucumber mutant, named yl, was found in an EMS-induced mutant library, which exhibited a significantly reduced chlorophyll content, abnormal chloroplast ultrastructure and decreased photosynthetic capacity. Genetic analysis demonstrated that the phenotype of yl was controlled by a recessive nuclear gene. Using BSA-seq technology combined with the map-based cloning method, we narrowed the locus to a 100 kb interval in chromosome 3. Linkage analysis and allelism test validated the candidate SNP residing in CsaV3_3G009150 encoding one homolog of chloroplast signal-recognition particle (cpSRP) receptor in Arabidopsis, cpFtsY, could be responsible for the yellow leaf phenotype of yl. The relative expression of CscpFtsY was significantly down-regulated in different organs except for the stem, of yl compared with that in the wild type (WT). Subcellular localization result showed that CscpFtsY located in the chloroplasts of mesophyll cells.

conclusionsThe yl mutant displayed Chls-deficient, impaired chloroplast ultrastructure with intermittent grana stacks and significantly decreased photosynthetic capacity. The isolation of CscpFtsY in cucumber could accelerate the progress on chloroplast development by cpSRP-dependant LHCP delivery system and regulation of Chls biosynthesis in a post-translational way.
