Abstract: The biosynthesis of anthocyanins is still questionable in regulating the quantities of anthocyanins biosynthesized in rice seeds and the expression levels of transcription factors and the structural genes involved in the biosynthetic pathway of anthocyanins. We herein investigated the relationship between the accumulated anthocyanin contents and the expression levels of genes related to the biosynthesis of anthocyanins in rice seeds. Liquid chromatography/mass spectrometry-mass spectrometry analysis of cyanidin 3-glucoside (C3G) in rice seeds showed no accumulation of C3G in white and red rice cultivars, and the differential accumulation of C3G among black rice cultivars. RNA-seq analysis in rice seeds, including white, red, and black rice cultivars, at twenty days after heading (DAH) further exhibited that the genes involved in the biosynthesis of anthocyanins were differentially upregulated in developing seeds of black rice. We further verified these RNA-seq results through gene expression analysis by a quantitative real-time polymerase chain reaction in developing seeds of white, red, and black rice cultivars at 20 DAH. Of these genes related to the biosynthesis of anthocyanins, bHLH s, MYB s, and WD40 , which are regulators, and the structural genes, including chalcone synthase ( CHS ), flavanone 3-hydroxylase ( F3H ), flavonoid 3´-hydroxylase ( F3 ´ H ), dihydroflavonol 4-reductase ( DFR ), and anthocyanidin synthase ( ANS ), were differentially upregulated in black rice seeds. The correlation analysis revealed that the quantities of C3G biosynthesized in black rice seeds were positively correlated to the expression levels of bHLH s, MYB s and WD40 , CHS , F3H , F3 ´ H , DFR , and ANS . In addition, we present bHLH2 ( LOC_Os04g47040 ) and MYB s ( LOC_Os01g49160 , LOC_Os01g74410 , and LOC_Os03g29614 ) as new putative transcription factor genes for the biosynthesis of anthocyanins in black rice seeds. It is expected that this study will help to improve the understanding of the molecular levels involved in the biosynthesis of anthocyanins in black rice seeds.

Abstract: Our previous research on coprolite specimens from the mummies of Joseon Dynasty (1392-1910 CE) has revealed various species of parasite eggs. Herein, we added 2 new helminthic cases of human remains from Joseon-period graves in the Republic of Korea (Korea). The organic materials precipitated on the hip bones of 2 half-mummied cases (Goryeong and Gwangmyeong cases) were collected, rehydrated, and examined by a microscope. In the sample from Goryeong-gun (gun=County), ova of 〈 i 〉 Trichuris trichiura, Clonorchis sinensis 〈 /i 〉 , and 〈 i 〉 Metagonimus 〈 /i 〉 spp. were detected, and eggs of 〈 i 〉 T. trichiura 〈 /i 〉 and 〈 i 〉 A. lumbricoides 〈 /i 〉 were found from the sample of Gwangmyeong-si (si=City). By adding this outcome to the existing data pool, we confirm our previous estimates of Joseon-period parasite infection rates. The overall rates of 〈 i 〉 A. lumbricoides, T. trichiura 〈 /i 〉 , and 〈 i 〉 C. sinensis 〈 /i 〉 decreased dramatically from Joseon to the modern period. In Goryeong mummy specimen, we also found 〈 i 〉 Metagonimus 〈 /i 〉 spp. eggs that has rarely been detected in archaeological samples so far.

Abstract: The resveratrol-producing rice ( Oryza sativa L.) inbred lines, Iksan 515 (I.515) and Iksan 526 (I.526), developed by the expression of the groundnut ( Arachis hypogaea ) resveratrol synthase 3 ( AhRS3 ) gene in the japonica rice cultivar Dongjin, accumulated both resveratrol and its glucoside, piceid, in seeds. Here, we investigated the effect of the AhRS3 transgene on the expression of endogenous piceid biosynthesis genes ( UGTs ) in the developing seeds of the resveratrol-producing rice inbred lines. Ultra-performance liquid chromatography (UPLC) analysis revealed that I.526 accumulates significantly higher resveratrol and piceid in seeds than those in I.515 seeds and, in I.526 seeds, the biosynthesis of resveratrol and piceid reached peak levels at 41 days after heading (DAH) and 20 DAH, respectively. Furthermore, RNA-seq analysis showed that the expression patterns of UGT genes differed significantly between the 20 DAH seeds of I.526 and those of Dongjin. Quantitative real-time PCR (RT-qPCR) analyses confirmed the data from RNA-seq analysis in seeds of Dongjin, I.515 and I.526, respectively, at 9 DAH, and in seeds of Dongjin and I.526, respectively, at 20 DAH. A total of 245 UGT s, classified into 31 UGT families, showed differential expression between Dongjin and I.526 seeds at 20 DAH. Of these, 43 UGT s showed more than 2-fold higher expression in I.526 seeds than in Dongjin seeds. In addition, the expression of resveratrol biosynthesis genes ( PAL , C4H and 4CL ) was also differentially expressed between Dongjin and I.526 developing seeds. Collectively, these data suggest that AhRS3 altered the expression pattern of UGT genes, and PAL , C4H and 4CL in developing rice seeds.

Abstract: In this study, we compared the quality characteristics of soft morning roll bread with different contents of two Korean high-yield tongil-type rice varieties, namely Hanareum4 and Keumkang1. The final and setback viscosities increased with increasing rice flour ratio as determined by a Rapid Visco Analyzer. The pH of the dough decreased as the rice flour ratio was decreased from 70% to 0%, regardless of the rice cultivar, and the dough rose more when less rice flour was added. During the final fermentation stage, the volumes of the dough containing Keumkang1 were 32.2, 27.5, 23.0, and 21.0 mL when 0, 30, 50, and 70% rice flour were added, respectively. The SEM images reveal that the dough forms a net-like morphology during fermentation, due to the decomposition of the wheat and rice flour. The volume and moisture contents of soft morning roll bread ranged in 90-192.5 mL and 38.25-40.06%, respectively. The volume of the Keumkang1-containing bread loaf was higher than that of the Hanareum4-containing loaf. Texture profile analysis (TPA) results suggest that the hardness and chewiness of the bread containing 30% Keumkang1 is very similar to that of the 100%-wheat bread regardless of rice varieties. The results suggest that Keumkang1 can replace wheat at a 30% level for morning roll bread purposes.
