Influence of different nitrogen inputs on the members of ammonium transporter and glutamine synthetase genes in two rice genotypes having differential responsiveness to nitrogen.
Article in Molecular biology reports, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Two aromatic rice genotypes, Pusa Basmati 1 (PB1) and Kalanamak 3119 (KN3119) having 120 and 30 kg/ha optimum nitrogen requirement respectively, to produce optimal yield, were chosen to understand their differential nitrogen responsiveness. Both the genotypes grown under increasing nitrogen inputs showed differences in seed/panicle, 1,000 seed weight, %nitrogen in the biomass and protein content in the seeds. All these parameters in PB1 were found to be in the increasing order in contrast to KN3119 which showed declined response on increasing nitrogen dose exceeding the normal dose indicating that both the genotypes respond differentially to the nitrogen inputs. Gene expression analysis of members of ammonium transporter gene family in flag leaves during active grain filling stage revealed that all the three members of OsAMT3 family genes (OsAMT1;1-3), only one member of OsAMT2 family i.e., OsAMT2;3 and the high affinity OsAMT1;1 were differentially expressed and were affected by different doses of nitrogen. In both the genotypes, both increase and decline in seed protein contents matched with the expressions levels of OsAMT1;1, OsGS1;1 and OsGS1;2 in the flag leaves during grain filling stage indicating that high nitrogen nutrition in KN3119 probably causes the repression of these genes which might be important during grain filling.
