| Abstract | Genetic factors of yield related traits in lowland New Rice for Africa variety (NERICA) using different nitrogen condition and QTL to increase rice yield in lowland NERICAs were clarified. Indica Group rice variety (Oryza sativa L.) IR64 increased panicle number, culm weight and panicle weight, according to nitrogen concentration. The tendency is especially remarkable under low nitrogen concentration. NERICA‒L‒19, which is derived from a cross between IR64 and TOG5681 (Oryza glaberrima S.), showed similar values for panicle weight and culm weight, and it showed higher plant height, panicle weight and culm weight and lower harvest index than those of IR64 under all the concentrations. QTL analysis for the agronomic traits were performed using hybrid population derived from a cross between IR64 and NERICA‒L‒19. A total of 22 QTLs were detected on chromosomes (chrs.) 1 (3 QTLs), 2 (2), 4 (2), 5 (5), 6 (1), 7 (1), 8 (6) and 10 (2). Among them, 4 regions at 34.1‒36.6Mbp of chr. 1, at 23.8‒27.8Mbp of chr. 5 and at 4.8Mbp and 20.3‒28.4Mbp of chr. 8 showed several QTLs’ peaks overlapped. The regions of chr. 5 and 4.8Mbp of chr. 8 increased panicle weight by IR64 allele. Those of chr. 1 and 20.3-28.4Mbp of chr. 8 increased plant height and harvest index, respectively, by NERICA‒L‒19 allele. These results indicated that the larger panicle type of lowland NERICA is suitable under low nitrogen condition. Also, the plant type was controlled by the combination of 4 QTLs’ regions on chr. 1 and short arm of chr. 8 originated from O. glaberrima, and those of chr. 5 and long arm of chr. 8 from O. sativa Indica Group. |

| Abstract | Cold wet treatment is frequently applied to Eustoma seeds to enhance the bolting rate of plants grown under high temperatures. Our previous study indicated that cold PEG‒primed Eustoma seeds could maintain their germination rate and bolting rate even after being re‒dried for 30days and grown under high temperatures. The present study aimed to investigate whether prolonged storage after cold PEG‒priming affect the germination, growth, and flowering of Eustoma ‘Exe Lavender’ seedling. Seeds were initially cold‒primed with water or PEG‒6000 at ‒1.5 MPa for 5 weeks at 10°C in the dark and were then subjected to re‒drying and storage for 30, 60, 90 and 360days at 10°C. After 360days of storage, cold PEG‒primed seeds germinated earlier and more effectively than cold hydro‒primed seeds. Compared to the results after 30days of storage, plants grown from 360days exhibited similar bolting rate, days to bolting, bolting node and flowering rate, cut flower length and number of flower node. These results suggest that ‘Exe Lavender’ seeds can germinate and develop well even after 360days of storage and under high temperature conditions when subjected to cold PEG‒6000 treatment. |

| Abstract | The authors have recently developed the overexpression profiling ADOPT method. In the ADOPT method, yeast strains overexpressing most of the genes in the budding yeast Saccharomyces cerevisiae genome are mixed and competitively cultured, and the genes overexpressed in the enriched strains are systematically identified. Furthermore, the identified genes can be used to identify bottleneck factors that are necessary but lacking for growth of S. cerevisiae under given conditions. In our previous studies, we have identified bottlenecks in artificially created stress environments in the laboratory, but in this study, we used grape juice for winemaking as an example to see if industrial bottlenecks can be identified. ADOPT experiments with sulfite-added grape juice used in conventional winemaking resulted in a strong enrichment of strains overexpressing the sulfite pump SSU1 and its transcription factor FZF1. Since enhancement of SSU1 function is known to occur in wine yeast acclimation, ADOPT was also shown to be useful in the search for industrial bottlenecks. On the other hand, no genes were strongly enriched by ADOPT in grape juice without sulfite addition, suggesting that grape juice is a balanced medium with few bottlenecks for S. cerevisiae growth. |
