Localization of nonspecific lipid transfer proteins correlate with programmed cell death responses during endosperm degradation in Euphorbia lagascae seedlings.

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
When the storage materials have been depleted, the endosperm cells undergo programmed cell death. Very little is known about how the components of the dying cells are recycled and used by the growing seedling. To learn more about endosperm degradation and nutrient recycling, we isolated soluble proteins from the endosperm of Euphorbia lagascae seedlings collected 2, 4, and 6 d after sowing. The protein extracts were subjected to two-dimensional gel electrophoresis. Proteins that increased in amount in the endosperm with time were selected for further analysis with mass spectrometry. We successfully identified 17 proteins, which became more abundant by time during germination. Among these proteins were three E. lagascae lipid transfer proteins (ElLTPs), ElLTP1, ElLTP2, and ElLTP3. Detailed expressional studies were performed on ElLTP1 and ElLTP2. ElLTP1 transcripts were detected in endosperm and cotyledons, whereas ElLTP2 transcripts were only detected in endosperm. Western blots confirmed that ElLTP1 and ElLTP2 accumulate during germination. Immunolocalization experiments showed that ElLTP1 was present in the vessels of the developing cotyledons, and also in the alloplastic space in the endosperm. ElLTP2 formed a concentration gradient in the endosperm, with higher amounts in the inner regions close to the cotyledons, and lesser amounts in the outer regions of the endosperm. On the basis of these data, we propose that ElLTP1 and ElLTP2 are involved in recycling of endosperm lipids, or that they act as protease inhibitors protecting the growing cotyledons from proteases released during programmed cell death.
