Genetic features of the spontaneous self-compatible mutant, 'Jin Zhui' (Pyrus bretschneideri Rehd.).

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
'Jin Zhui' is a spontaneous self-compatible mutant of 'Ya Li' (Pyrus bretschneideri Rehd. S21S34 ), the latter displaying a typical S-RNase-based gametophytic self-incompatibility (GSI). The pollen-part mutation (PPM) of 'Jin Zhui' might be due to a natural mutation in the pollen-S gene (S34 haplotype). However, the molecular mechanisms behind these phenotypic changes are still unclear. In this study, we identified five SLF (S-Locus F-box) genes in 'Ya Li', while no nucleotide differences were found in the SLF genes of 'Jin Zhui'. Further genetic analysis by S-RNase PCR-typing of selfed progeny of 'Jin Zhui' and 'Ya Li' × 'Jin Zhui' progeny showed three progeny classes (S21S21 , S21S34 and S34S34 ) as opposed to the two classes reported previously (S21S34 and S34S34 ), indicating that the pollen gametes of 'Jin Zhui', bearing either the S21 - or S34 -haplotype, were able to overcome self-incompatibility (SI) barriers. Moreover, no evidence of pollen-S duplication was found. These findings support the hypothesis that loss of function of S-locus unlinked PPM expressed in pollen leads to SI breakdown in 'Jin Zhui', rather than natural mutation in the pollen-S gene (S34 haplotype). Furthermore, abnormal meiosis was observed in a number of pollen mother cells (PMCs) in 'Jin Zhui', but not in 'Ya Li'. These and other interesting findings are discussed.
