Dismantling of Arabidopsis thaliana mesophyll cell chloroplasts during natural leaf senescence.

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
One of the earliest events in the process of leaf senescence is dismantling of chloroplasts. Mesophyll cell chloroplasts from rosette leaves were studied in Arabidopsis thaliana undergoing natural senescence. The number of chloroplasts decreased by only 17% in fully yellow leaves, and chloroplasts were found to undergo progressive photosynthetic and ultrastructural changes as senescence proceeded. In ultrastructural studies, an intact tonoplast could not be visualized, thus, a 35S-GFP::delta-TIP line with a GFP-labeled tonoplast was used to demonstrate that chloroplasts remain outside of the tonoplast even at late stages of senescence. Chloroplast DNA was measured by real-time PCR at four different chloroplast loci, and a fourfold decrease in chloroplast DNA per chloroplast was noted in yellow senescent leaves when compared to green leaves from plants of the same age. Although chloroplast DNA did decrease, the chloroplast/nuclear gene copy ratio was still 31:1 in yellow leaves. Interestingly, mRNA levels for the four loci differed: psbA and ndhB mRNAs remained abundant late into senescence, while rpoC1 and rbcL mRNAs decreased in parallel to chloroplast DNA. Together, these data demonstrate that, during senescence, chloroplasts remain outside of the vacuole as distinct organelles while the thylakoid membranes are dismantled internally. As thylakoids were dismantled, Rubisco large subunit, Lhcb1, and chloroplast DNA levels declined, but variable levels of mRNA persisted.
