Construction of restorer lines and molecular mapping for restorer gene of hau cytoplasmic male sterility in Brassica napus.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
key messageSuccessfully constructing restorer lines for the hau CMS line and molecular mapping of Rfh to a 94 kb candidate region on chromosome A03 in Brassica napus. Cytoplasmic male sterility is a general phenomenon in almost 200 species, and the interaction between chimeric genes in mitochondria and restorer genes in nucleus may be responsible for restoration of male fertility. Orf288 has been identified as a CMS-associated gene in the hau CMS line of Brassica napus and Brassica juncea; however, the restorer lines/genes have not been found yet. We therefore have successfully constructed two restorer lines in B. napus by extensive testcrossing and have mapped a major restorer gene Rfh to a physical distance of 94 kb on chromosome A03 by whole-genome resequencing and molecular markers. We found that the restorer line is indeed restored to male fertility at histological level. Comparative genomics and collinearity analysis between close relatives revealed that rearrangements and recombination may have happened and thus caused the production of Rfh or components of the restoration of fertility complex. Meanwhile, nuclear backgrounds with multiple loci and temperature were related to the variation and instability of restoration of fertility in three different populations. Our study provides new sights into the coevolution between restorer genes and CMS-associated genes as well as the cultivation of superior hybrids via molecular breeding.
