A comparative light and electron microscopic analysis of microspore and tapetum development in fertile and cytoplasmic male sterile radish.
Article in Protoplasma, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
To gain further insight into the abortive stages and ultrastructural changes leading to pollen degeneration of a novel cytoplasmic male sterile radish 805A, we compared differences of cellular and subcellular structure of sterile anther with fertile anther by light and electron microscopy analysis. Two types of locule degeneration in sterile anther were detected, of which the time of degeneration occurred and completed was different. In type I, abnormality of pollen mother cells (PMCs) and tapetal cells, including condensation of cytoplasm and large vacuoles within tapetal cells, was shown at PMC stage. In type II, meiosis and early tetrad stage progressed normally except for large vacuoles that appeared in tapetal cells. Ultrastructural alterations of the cellular organization were observed in the type II locules, such as chromatin condensation at the periphery of the nucleus and degeneration of the karyotheca, compared with normal pollen development. The results suggested that the cytoplasmic male sterility anther degeneration was probably caused by dysfunctions of tapetum and vacuolation of tapetum, PMCs, and microspores. Thus, the identical factors, which induced CMS in the same cytoplasmic and nuclear genetic background, might affect development of tapetum and microspore at different stages during the cytoplasmic male sterile 805A anther development.
