Post-Transcriptional Control of Gene Expression in Plants

A up to date quantity of this sequence (Signals and sign TransductionPathways in crops (K. Palme, ed. ) Plant Molecular Biology26, 1237-1679) defined the relay races wherein signs are transported in crops from the websites of stimuli to the gene expression equipment of the mobile. a part of this equipment, the transcription gear, has been good studied within the final 20 years, and plenty of vital mechanisms controlling gene expression on the transcriptional point were elucidated.

The stomach was removed, washed, extracted and analysed by TLC. Also five polysulfide derivatives of carbosulfan or of carbofuran [4 (n =2-3) and 51 were detected as minor products (Umetsu and Fukuto, 1982). P. R. (1980) J. Agric.

1975). [14C-ring]Benfuracarbwas applied topically to houseflies. Flies were extracted and analysed at intervals up to 24 hours. Penetration of applied radioactivity was rapid and extensive (65% of that applied). Pathways of metabolism were similar to those for plants (Scheme 2). Principal reactions in the housefly were N-S bond cleavage, oxidation, hydrolysis and conjugation. Benfuracarb was readily decomposed to form carbofuran which was in turn oxidised at the 3-position and at the N-methyl group.

14C-caubonyl]-,[14C-dibutylarnino]-or [14C-ring]-Carbosulfanwere orally administered to rats. Samples of urine, faeces and blood were taken at intervals up to 96 hours. Radioactivity eliminated after 24 hours as C02 Carbarnates Carbosulfan 37 from [14C-carbonyl]carbosulfanrepresented 6 5 4 5 % of that administered. Radioactivity eliminated in urine from [14C-ring]carbosulfanrepresented S O % and from [14C-dibutylamino]carbosulfan>50% after 24 hours. A large was recovered from faeces. The carbofuran was then metabolised via hydrolysis and oxidation to metabolites 7, 8,9 and 10.
