Integration of cerium chemical forms and subcellular distribution to understand cerium tolerance mechanism in the rice seedlings.

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
Rare earth elements (REEs) accumulate in the soil and ecosystem. Cerium (Ce) is one of the main additives in REE-containing fertilizers. However, little information is available on Ce distribution patterns and chemical forms in rice. The subcellular distribution and chemical forms of Ce were investigated in the rice seedlings (Oryza sativa L., cv. Zhonghua 11) exposed to 0, 10, 20, 40, 80, and 160 μM Ce. The elongation of root and shoot was significantly inhibited by 20, 40, 80, and 160 μM Ce. Cerium was significantly accumulated in the cell walls, cell organelles, and soluble fractions of the roots and shoots with the increase of Ce concentrations. The concentrations of Ce in roots were significantly higher than shoots, and a large amount of Ce was stored in cell walls. In addition, Ce existed in the different chemical forms in the rice seedlings, and there were most insoluble oxalate or phosphate forms in roots. The subcellular distribution and chemical forms of Ce were closely associated with the metal tolerance and detoxification of rice.
