The amino acid sequence of a novel trypsin inhibitor (p20) was completed by the molecular cloning of the protein in cultured soybean cells. The clone nucleotide contains an open reading frame encoding a polypeptide of 206 amino acids that shows 45-50% sequence homology to members of the Kunitz-type trypsin inhibitor family. The p20 transcript is expressed(More)
In this paper, we propose four slicing methods using both static and dynamic analysis information. (1) StatementMark Slice : removes the unnecessary statements using an execution history of the statements. (2) Partial Program Analysis : reduces the static analysis cost using invocation history of procedures. (3) Dynamic Data Dependence Analysis : extracts(More)
Cisplatin (CDDP) is a potent DNA-damaging anticancer agent, and its cytotoxic action is exerted by the induction of apoptosis. However, activation of the transcription factor NF-kappaB results in protection against apoptosis. We examined the molecular mechanisms involved in the induction of apoptosis by CDDP as regards both suppression of NF-kappaB and(More)
Genes for two geraniol-responsive factors, designated McEREBP1 and McWRKY1, from cultured shoot primordia of Matricaria chamomilla were cloned. The deduced amino acid sequences of these genes were highly similar to those of the family of ethylene-responsive element binding proteins and elicitor-induced DNA-binding proteins containing a WRKY domain,(More)
A peroxidase was purified from the culture medium of a suspension culture of Marchantia polymorpha (liverwort) after treatment with bornyl acetate, which acts as a chemical stress agent to the cells. The peroxidase was characterised as a glycoprotein of molecular mass 37-kDa having a pl of about 10 and an optimal pH of 6.5. The peroxidase was thermally(More)
An NADP+-dependent alcohol dehydrogenase (allyl-ADH) was isolated from the cultured cells of Nicotiana tabacum. The allyl-ADH was found to be efficient for the dehydrogenation of secondary allylic alcohols rather than saturated secondary alcohols and it was specific for the S-stereoisomer of the alcohols. The enzyme catalyzed the reversible reaction whereby(More)
When the cultured cells of Glycine max (soybean) were treated with 5 mM geraniol as a chemical stress, an mRNA level was elevated in a rapid but transient increase. The mRNA was cloned and sequenced, and found to correspond to the mRNA encoding glutathione S-transferase (GST). The GST mRNA level and GST activity were elevated to maxima at 4-6 h and 8 h,(More)
We have isolated a full-length cDNA clone from the cultured cells of Nicotiana tabacum, of which the deduced 225 amino acid sequence showed significant homology to the known ethylene-responsive element binding proteins (EREBPs) from tobacco and Arabidopsis. Although the clone shared substantial homology with an Arabidopsis ethylene-responsive element(More)
When we try to debug a large program e ectively, it is very important to separate a suspicious program portion from the overall source program. Program slicing is a promising technique to extract a program portion; however, it remains diÆcult issues. Static slicing sometimes produces a large portion of the source program, especially for a program with(More)
