Differential expression of carotenoid biosynthetic pathway genes in two contrasting tomato genotypes for lycopene content.
Article in Journal of biosciences, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Tomato (Solanum lycopersicum L.) is one of the model plant to study carotenoid biosynthesis. In the present study, the fruit carotenoid content were quantified at different developmental stages for two contrasting genotypes, viz. IIHR-249-1 and IIHR-2866 by UPLC. Lycopene content was high in IIHR-249-1 (19.45 mg/100 g fresh weight) compared to IIHR-2866 (1.88 mg/100 g fresh weight) at the ripe stage. qPCR was performed for genes that are involved in the carotenoid biosynthetic pathway to study the difference in lycopene content in fruits of both the genotypes. The expression of Phytoene synthase (PSY) increased by 36-fold and Phytoene desaturase (PDS) increased by 14-fold from immature green stage to ripe stage in IIHR-249-1. The expression of Chloroplast lycopene beta-cyclase (LCY-B) and Chromoplast lycopene beta cyclase (CYC-B) decreased gradually from the initial stage to the ripe stage in IIHR-249-1. IIHR 249-1 showed 3- and 1.8-fold decrease in gene expression for Chloroplast lycopene beta-cyclase (LCY-B) and Chromoplast lycopene beta-cyclase (CYC-B) .The F2 hybrids derived from IIHR-249-1 and IIHR-2866 were analysed at the ripe stage for lycopene content. The gene expression of Chloroplast lycopene beta-cyclase (LCY-B) and Chromoplast lycopene beta-cyclase (CYC-B) in high and low lycopene lines from F2 progenies also showed the decrease in transcript levels of both the genes in high lycopene F2 lines. We wish to suggest that the differential expression of lycopene beta-cyclases can be used in marker-assisted breeding.
