Biomarker-based evaluation of cytogenotoxic potential of glyphosate in Vigna mungo (L.) Hepper genotypes.

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
Herbicides have proven to be a boon for agricultural fields. Their inherent property to kill weeds and unwanted vegetation makes them an essential biological tool for farmers and agricultural systems. Besides being capable of destroying weeds, they also exhibit certain effects on non-target crop plants. In the present study, a laboratory experiment was performed to assess the effect of glyphosate on Vigna mungo root meristem cells. Seeds of five different genotypes of V. mungo were treated with a series of concentrations of glyphosate ranging from 1 to 10 mM, and their effects on mitotic cell division were studied. Healthy and uniform-sized seeds were selected and were allowed to grow in Petri plates for 3 days, and all the doses were maintained in triplicates. Roots were fixed at day 3 after treatment (DAT) for cytological microscopic slide preparation. The results obtained indicate the dose-dependent reduction in the mitotic index in all the genotypes and an increase in the percentage of chromosomal aberrations (CAs) and relative abnormality rate (RAR). Most commonly observed chromosome aberrations at lower doses (< 6 mM) were fragments, stickiness, and disoriented metaphase, while at higher doses (6 to 10 mM) bridges, laggards, spindle disorientation, and clumping were obvious. The increase in the percentage of CAs and RAR indicates the inhibitory effect of glyphosate on cell cycle progression at various stages in root tip cells. The present study is a fine example of a biomarker-based genotoxic assessment of mitotic damage caused by glyphosate.
