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

MAIN

conclusionWe cloned two variants of lipase gene-MAGL and TAGL from pearl millet. Lipase showed negative correlation with antioxidants and total phenolics. FAA can be used as marker for rancidity. Pearl millet is considered as "Nutri-cereal" due to its rich nutrient profile. Low keeping quality of the flour due to rancidity is one of the major problems in pearl millet. Lipases are a group of enzymes that produces free fatty acids that ultimately leads to rancidity. Very few lipases have been identified and characterized from pearl millet. Here, we have identified 2039 transcripts of lipases from pooled samples (leaf, stem and developing grains) of pearl millet using de novo transcriptomic approach and predicted 05 full length lipase variants. Further, we cloned 02 lipase genes-monoacylglycerol lipase (MAGL, acc. no. MZ590564) and triacylglycerol lipase (TAGL, acc. no. MZ590565) of 1.5 kb each from pearl millet cv. Pusa-1201. Conserved domain search analysis showed the presence of catalytic triad [GXSXG] near the active site which is signature domain of lipase family of proteins. MAGL showed maximum expression in PC-701 and TAGL in Pusa-1201 during mealy-ripe growth stage of endospermic tissue. Abundance of transcripts of both the lipases was observed in the harvested grains of PC-701. We observed negative correlation between the lipase activity and accumulation of antioxidants like total phenolic content (TPC), tannin, and total antioxidant potential (TAP). Free amino acid and reducing sugar were observed as potential markers for accessing the intensity/extent of rancidity in pearl millet flour. Thus, there is need to explore and characterize the lipase variants to connect the missing dots in rancidity pathway and to use it in genome editing using the CRISPR/Cas9 approach for the development of pearl millet lines free of off-odor and flour rancidity.
