Arabidopsis TT19 encodes a GST-like protein that is involved in the accumulation of proanthocyanidins (PAs) in the seed coat. PA accumulation sites in tt19 immature seeds were observed as small vacuolar-like structures, which show unique thick morphology by differential interference contrast microscopy. The distribution pattern of the thick structures overlapped the location of PA accumulation sites in tt19. Metabolic profiling of the solvent-soluble fraction demonstrated that PA derivatives such as epicatechins and epicatechin oligomers, although highly accumulated in the wild-type, were absent in tt19. We also revealed that tt12 specifically accumulated glycosylated epicatechins, the putative transport substrates for TT12. Given the cytosolic localization of functional GFP-TT19 proteins, our results suggest that TT19, which acts prior to TT12, functions in cytosol for regular accumulation of PA precursors such as epicatechin and glycosylated epicatechin in the vacuole.

The authors obtain a new equation to estimate the forward component of a photon dose which is generated through the interaction between a target and a short pulse high power laser. As the equation is quite simple, it is useful for calculating the photon dose. The equation shows that the photon dose is proportional to the electron temperature for the range of its temperature $$>$$ 3 MeV, and proportional to square of the electron temperature for the range of its temperature $$<$$ 3 MeV. The dose estimated with this method is roughly consistent with the result of Monte Carlo simulation. On someassumptions and corrections, it can reproduce experimental results obtained and the dose result calculated at other laboratories.

Arabidopsis TRANSPARENT TESTA19 (TT19) is involved in the accumulation of proanthocyanidins (PAs) in the seed coat. PA accumulation sites in tt19 immature seeds were observed as small vacuolar-like structures, whereas those in tt12, a mutant of the tonoplast-bound transporter of PAs, and tt12 tt19 were observed at peripheral regions of small vacuoles. We found that tt19 immature seeds had small spherical structures showing unique thick morphology by differential interference contrast microscopy. The thick structures were outlined with GFP-TT12 proteins in tt19. Metabolic profiling demonstrated that PA derivatives such as epicatechins and epicatechin oligomers were absent in tt19. Given the cytosolic localization of functional GFP-TT19 proteins, the PA pathway in Arabidopsis seed coat is discussed in relation to the subcellular localization of PA metabolites.
