Gene expression profiling in rice young panicle and vegetative organs and identification of panicle-specific genes through known gene functions.
Article in Molecular genetics and genomics : MGG, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
In rice, at the stage from pistil and stamen primordia formation to microsporocyte meiosis, the young panicle organs (YPO) make a great contribution to grain productivity. This period corresponds to the onset of meiosis and marks the transition from vegetative to reproductive stages. By comparing gene expression profiling of YPO with that of rice aerial vegetative organs (AVO), it is possible to gain further molecular insight into this period that is developmentally and functionally important. In this report, a total of 92,582 high-quality ESTs from 5'-end sequencing, including 44,247 from YPO and 48,335 from AVO, were obtained and classified. There were 12,884 (29.12%) ESTs from YPO and 16,304 (33.73%) ESTs from AVO matched to known genes, which generated 1,667 and 2,172 known genes, respectively, after integration of these ESTs. From the functions of known homologous genes, we identified some tissue- and developmental-stage-specified genes in YPO. The expression of these genes clearly reflected the unique functional characteristics of YPO. Furthermore, we estimated that there are about 10,000 mRNAs specifically expressed in rice YPO.
