Transgenic tobacco (Nicotiana tabacum cv. LA Burley 21) lines expressing three genes encoding enzymes thought to be critical for the efficient production of phytochelatins, (i) serine acetyltransferase (EC 2.3.1.30) involved in the production of O-acetylserine, the cysteine precursor, (ii) gamma-glutamylcysteine synthetase (EC 6.3.2.2) involved in the(More)
In Escherichia coli, heterologous production of Schizosaccharomyces pombe phytochelatin synthase (PCS) along with overproduction of E. coli serine acetyltransferase (SAT) and gamma-glutamylcysteine synthase (gammaECS) was achieved and resulted in the accumulation of phytochelatins in bacterial cells. Overproduction of either gammaECS alone or simultaneous(More)
In contrast to mRNAs, ribosomal RNAs are generally not considered to be polyadenylated. Only a few recent reports describe non-abundant polyadenylated rRNA-related transcripts that have been detected and characterized in yeast and in human cells. Here we depict the phenomenon of 26S rRNA polyadenylation and degradation that was observed in shoots of(More)
