Clubroot resistance gene Rcr6 in Brassica nigra resides in a genomic region homologous to chromosome A08 in B. rapa.

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
backgroundClubroot, caused by Plasmodiophora brassicae Woronin, is a very important disease of Brassica species. Management of clubroot relies heavily on genetic resistance. In a cross of Brassica nigra lines PI 219576 (highly resistant, R) × CR2748 (highly susceptible, S) to clubroot, all F
resultsReads of R and S bulks from BSR-Seq were initially aligned onto B. rapa (A-genome; B. nigra has the B-genome) where Rcr6 was associated with chromosome A08. KASP analysis showed that Rcr6 was flanked by SNP markers homologous to the region of 14.8-15.4 Mb of chromosome A08. There were 190 genes annotated in this region, with five genes (Bra010552, Bra010588, Bra010589, Bra010590 and Bra010663) identified as encoding the toll-interleukin-1 receptor / nucleotide-binding site / leucine-rich-repeat (TIR-NBS-LRR; TNL) class of proteins. The reads from BSR-Seq were then aligned into a draft B-genome of B. nigra, where Rcr6 was mapped on chromosome B3. KASP analysis indicated that Rcr6 was located on chromosome B3 in a 0.5 Mb region from 6.1-6.6 Mb. Only one TNL gene homologous to the B. rapa gene Bra010663 was identified in the target region. This gene is a likely candidate for Rcr6. Subsequent analysis of the Rcr6 equivalent region based on a published B. nigra genome was performed. This gene is located into chromosome B7 of the published B-genome, homologous to BniB015819.
conclusionRcr6 was the first gene identified and mapped in the B-genome of Brassica species. It resides in a genomic region homologous to chromosome A08 of A-genome. Based on this finding, it could possibly integrate into A08 of B. napus using marker assisted selection with SNP markers tightly linked to Rcr6 developed in this study.
