The effects of the hydraulic retention time (HRT=8, 10, 12 or 16.7 h) and glucose concentration (30, 40 or 50 g/L) on the production of hydrogen and butyrate by an immobilized Clostridium tyrobutyricum culture, grown under continuous culturing conditions, were evaluated. With 30 g/L glucose, the higher HRTs tested led to greater butyrate concentrations in(More)
The p53 gene plays a determinant role in radiation-induced cell death and its protein product is negatively regulated by MDM2. We investigated whether adenovirus-mediated modified p53 gene transfer, which blocks p53-MDM2 binding, is effective for radiation-induced cell death in hepatocellular carcinoma (HCC) at different MDM2 cellular levels. Human(More)
Plant growth promoting rhizobacteria (PGPR) are known to confer disease resistance to plants. Bacillus sp. JS demonstrated antifungal activities against five fungal pathogens in in vitro assays. To verify whether the volatiles of Bacillus sp. JS confer disease resistance, tobacco leaves pre-treated with the volatiles were damaged by the fungal pathogen,(More)
A novel gene, denoted IbEF1isolated from sweet potato corresponded to the most abundant mRNA present in root tissue under salt stress. However, the encoded protein did not accumulate in the shoots. Transgenic tobacco plants were generated to elucidate the physiological function of IbEF1. The extent of early flowering of these plants correlated well with the(More)
The elongation factor GSL-Elong and myrosinase, which are essential for sulforaphane biosynthesis, were cloned for the first time from broccoli (Brassica oleracea var. italica) and were designated as Bro-GS-elong and Bro-myro. Sequence analysis of Bro-GS-elong and Bro-myro revealed that its full length cDNA was 1787 bp long and included a 1464 bp open(More)
The cDNA of the touch-induced genes (TCH) of the sweet potato [Ipomoea batatas (L.) Lam.] has been cloned and analyzed. IbTCH1, which exists as at least two-copy genes in the genome of the sweet potato, encodes for 148-amino acid polypeptides, and harbors four conversed Ca2+-binding motif EF-hands. IbTCH1 was shown to be expressed in the flower, leaf, thick(More)
A previous study revealed that IbEF1 from sweet potato promoted early flowering in transgenic tobacco and acted as a novel regulator involved in flowering time control. Two putative ortholog genes were found in N. tabacum: NtEF1 and NtEF2. Subcellular localization of NtEF1 and NtEF2 with an in vivo targeting approach revealed that NtEF1 and NtEF2 were(More)
Specific bacterial strains that promote plant growth have been investigated extensively and are characterized as plant growth-promoting rhizobacteria (PGPR). To identify the series of genes involved in PGPR-mediated enhanced plant growth, suppression subtractive hybridization was performed using cDNA from tobacco plants exposed to the PGPR strain, Bacillus(More)
