Introns 2 and 4 of the psbA gene of Chlamydomonas reinhardtii chloroplasts (Cr.psbA2 and Cr.psbA4, respectively) contain large free-standing open reading frames (ORFs). We used transformation of an intronless-psbA strain (IL) to test whether these introns undergo homing. Each intron, plus short exon sequences, was cloned into a chloroplast expression vector(More)
Polypeptide synthesis using either phenylalanine or lysine was initiated on Escherichia coli ribosomes; then the position and conformation of the nascent peptide were monitored by fluorescence techniques. To this end, fluorophores had been attached to the amino terminus of each nascent peptide, and major differences were observed as chain extension(More)
We are developing Chlamydomonas strains that can be used for safe and sustainable control of mosquitoes, because they produce proteins from Bacillus thuringiensis subsp. israelensis (Bti) in the chloroplast. Chlamydomonas has a number of advantages for this approach, including genetic controls that are not generally available with industrial algae. The Bti(More)
Reaction of 5S RNA with chlorocetaldehyde leads to the conversion of unpaired adenines to the fluorescent 1,N6-etheno-adenine derivatives. Up to 16 of the 23 adenines in free 5S RNA can be modified, the fastest reacting are A29, A34, A57-59. Partial modification of adenines in this area results in a 20% reduction in the efficiency of 5S RNA incorporation(More)
