Season- and age-associated telomerase activity in Ginkgo biloba L.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Telomeres have lately received considerable attention in the development of broad-leaved tree species. In order to determine tissue-, sex-, season- and age-specific changes in telomerase activity in ginkgo trees, analyses of the telomerase repeat amplification protocol were carried out. In all of the tissues detected (embryonal callus, microspore tissues and leaves) telomerase activity was found, with differences between these activities statistically significant (P < 0.05). The highest telomerase activity was found in embryonal callus, suggesting that ginkgo trees have tissue-specific telomerase activity. Tissues containing high levels of dividing cells also have high levels of telomerase activity. No significant difference of telomerase activity was found between male and female trees (P > 0.05). In the annual development cycle, the highest telomerase activity was found in April and a decreasing trend over time in the four age groups studied: 10, 20, 70 and 700 year. The most obvious decline appeared in trees of the 700 year old group, suggesting that ginkgo trees have season-specific telomerase activities and trees of various ages react differently to seasonal changes. The mean annual telomerase activity showed a regular decreasing trend in all leaf samples analyzed from 10 to 700 year old ginkgo trees. We conclude that maintenance of telomere length depends on season- and age- associated telomerase activity. An optimal telomere length is regulated and maintained by telomerase in Ginkgo biloba L.
