1 · What the graph read from it

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.

2 · The registry

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

backgroundGossypium anomalum (BB genome) possesses the desirable characteristics of drought tolerance, resistance to diseases and insect pests, and the potential for high quality fibers. However, it is difficult to transfer the genes associated with these desirable traits into cultivated cotton (G. hirsutum, AADD genome). Monosomic alien addition lines (MAALs) can be used as a bridge to transfer desired genes from wild species into G. hirsutum. In cotton, however, the high number and smaller size of the chromosomes has resulted in difficulties in discriminating chromosomes from wild species in cultivated cotton background, the development of cotton MAALs has lagged far behind many other crops. To date, no set of G. hirsutum-G. anomalum MAALs was reported. Here the amphiploid (AADDBB genome) derived from G. hirsutum × G. anomalum was used to generate a set of G. hirsutum-G. anomalum MAALs through a combination of consecutive backcrossing, genomic in situ hybridization (GISH), morphological survey and microsatellite marker identification.

resultsWe improved the GISH technique used in our previous research by using a mixture of two probes from G. anomalum and G. herbaceum (AA genome). The results indicate that a ratio of 4:3 (G. anomalum : G. herbaceum) is the most suitable for discrimination of chromosomes from G. anomalum and the At-subgenome of G. hirsutum. Using this improved GISH technique, 108 MAAL individuals were isolated. Next, 170 G. hirsutum- and G. anomalum-specific codominant markers were obtained and employed for characterization of these MAAL individuals. Finally, eleven out of 13 MAALs were identified. Unfortunately, we were unable to isolate Chrs. 1B

conclusionsThe characterized lines can be employed as bridges for the transfer of desired genes from G. anomalum into G. hirsutum, as well as for gene assignment, isolation of chromosome-specific probes, development of chromosome-specific "paints" for fluorochrome-labeled DNA fragments, physical mapping, and selective isolation and mapping of cDNAs/genes for a particular G. anomalum chromosome.
