摘要:
An object of the present invention is to identify sequence features of the 5′ UTR, which are involved in changes in the translational state of plants under environmental stresses, and to provide a recombinant DNA molecule, an expression vector, a transformant, and the like, having the above sequence features. The present invention provides a recombinant DNA molecule encoding mRNA containing the 5′ UTR (a) or (b) defined below, a vector obtained by ligating the recombinant DNA molecule to a site immediately downstream of the transcription initiation point of a promoter, and a transformant comprising the vector:(a) 5′ UTR in which a sequence of bases 1 to 7 and a sequence of bases 12 to 32 from the 5′ end are, respectively, a sequence of bases 1 to 7 and a sequence of bases 12 to 32 of SEQ ID NO: 4, 6, 20, 36, or 60; and(b) 5′ UTR in which one or more bases in the base sequence of the 5′ UTR of (a) are replaced, and which escapes translational repression induced by at least one environmental stress selected from the group consisting of heat stress and salt stress.

摘要:
A process for the preparation of a 5,5'-bi-1H-tetrazole diammonium salt by using dicyan, sodium azide, ammonium chloride and water as a reaction medium. This process is industrially advantageous since the 5,5'-bi-1H-tetrazole diammonium salt is synthesized and, then, the precipitated crystals thereof are simply isolated by filtration to obtain the 5,5'-bi-1H-tetrazole diammonium salt maintaining an yield which is not lower than 90%. The 5,5'-bi-1H-tetrazole diammonium salt is a gas-generating agent for air bags, which is lowly toxic and is easy to handle.
