Evaluation of herbicidal potential of Siderophores produced by Amycolatopsis lurida strain 407.

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
The urgent need for sustainable agriculture has intensified the search for environmentally friendly alternatives to chemical herbicides. This study investigates the herbicidal potential of siderophores produced by Amycolatopsis lurida strain 407, focusing on its effects on the growth of ryegrass and redroot weeds. Strain 407 exhibited two distinct colony morphologies-red and white-when cultured under varying environmental conditions. The cell-free culture filtrate (CFCF) from both colony types significantly inhibited the growth of ryegrass and redroot. The concentration of siderophore produced in the iron-deficient medium was measured to be 613.4 ppm for 407 red and 388.5 ppm for 407 white, which indicates significant iron chelating activity. This study also showed a direct relationship between the presence of siderophore in plant culture medium and reduced growth. Also, analysis of fractions of the aqueous phase resulting from column chromatography revealed that all fractions from the 407 red reduced ryegrass shoot length by up to 45% and root length by 83-86%, while redroot seedling length decreased by up to 36%. Fractions from 407 white completely inhibited germination or reduced ryegrass root length by up to 94% and redroot seedling length by 52%. Fractions F4 W to F7 W and F2 R to F8 R, which showed iron chelating activity were most effective in reducing plant growth, suggesting that there are metabolites, alone or in company with siderophores, synergistically do herbicidal activity. The innovative application of siderophores as bioherbicide presents a promising environmentally friendly alternative to chemical herbicides.
