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

backgroundKarnal bunt of wheat is an important quarantine disease, incited by Tilletia indica. It limits India's trade in wheat export. The teliospores are major source of inoculum to initiate and spread the Karnal bunt disease. The study aimed to identify the germination-related genes in the teliospores of T. indica. METHODS AND

resultsThe candidate genes in the teliospores germination were identified through the differential gene expression analysis with suitable bioinformatics analysis. Keeping in soil-borne nature of fungi, the teliospores of T. indica (2015 and 2018) were subjected to the qPCR analysis. 20 candidate genes were identified having role in germination of teliospores of T. indica. Twenty genes, viz. Ti9297 (9.31, 7.87-fold), Ti8696 (5.13, 6.54-fold), Ti7699 (8.9, 7.7-fold), Ti7858 (10.33, 6.21-fold), Ti7954 (7.46, 5.54-fold), Ti7739 (5.46, 6.46-fold), Ti9665 (10.74, 7.64-fold), Ti9335 (6.75, 4.36-fold), Ti8396 (9.35, 7.72-fold), Ti8126 (8.87, 11.31-fold), Ti7326 (6.04, 7.7-fold), Ti10208 (13.83, 5.81-fold), Ti12356 (7.83, 8.02-fold), Ti14271 (9.98, 6.32-fold), Ti9234 (11.2, 8.72-fold), Ti 8876 (6.47, 3.55-fold), Ti 10,606 (4.97, 2.35-fold), Ti7758 (10.33, 8.78-fold), Ti4692 (6.89, 9.88-fold), and Ti3932 (5.77, 4.5-fold) were found highly expressed in the germinating teliospores of 2015 and 2018, respectively. Eight genes (Ti508, Ti4152, Ti5346, Ti2375, Ti3739, Ti1134, Ti4399, and Ti4422) were downregulated in the germinating teliospores but these eight genes were showed higher expression in the dormant teliospores.

conclusionsTwenty candidate genes were upregulated in the germinating teliospores are supposed to be involved in the process of germination. Eight genes were downregulated which were related to the process of the dormancy of teliospores. The study will be helpful to devise the newer management strategies for Karnal bunt disease of wheat.
