(6) The ability of the recombinant to utilize 3-chlorobenzoate, chlorobenzene, and 1,4-dichlorobenzene as well as its loss of utilization of xylenes and methylbenzoates appears to be associated with the transfer and integration of chromosomal DNA from P. alcaligenes into a Tol-like plasmid of P. putida R5-3.
(7) In the present study, the wild-type alleles at the tol locus were introgressed reciprocally, from N. crassa into N. tetrasperma and from N. tetrasperma into N. crassa, to investigate the action of these alleles in the A+a heterokaryon incompatibility systems of these species.
(8) Transfer of TOL(*) via factor K or TOLDelta is mediated by the formation of plasmid cointegrates; no recombination is observed with CAM.

(12) Thus, each naturally occurring TOL plasmid in this study appears to carry genes for two meta cleavage dioxygenases.
(13) In cultures prepared from 15- and 20-day-old rats, TOL had no apparent effect on rABP secretion, but reduced rTF and increased rTB secretion.
(14) The in vivo clearance of tolbutamide (TOL), theophylline (TH), antipyrine (AP) and its metabolites were determined in the same rats used for hepatic microsome preparation and assessment of P450 content and activities (via 7-ethoxycoumarin O-deethylase (ECOD), 7 ethoxyresorufin O-deethylase, 7-methoxycoumarin O-demethylase (MCOD) and aldrin epoxidase determinations).
(15) The xylR gene is a regulatory gene on the TOL plasmid, which acts in a positive manner on xyl operons for degradation of toluene and xylenes in Pseudomonas putida.
(16) It is concluded that the exb- and tol-dependent systems originate from a common uptake system for biopolymers.
(17) We have used this procedure to assemble in monocopy in Pseudomonas putida the regulatory elements controlling expression of the XylS-activated Pm promoter of the TOL catabolic plasmid pWWO.
(18) Thus, the increased utilizability seen in a mutant strain appeared to be due to an increased quantity of the enzymes coded by the TOL plasmid.
(19) Plasmids were constructed which led to an overproduction of the Tol proteins involved in the import of group A colicins.
(20) The most responsive parameters--TOL and AP clearances, MCOD and ECOD activities--were also those producing the strongest in vivo-in vitro correlations.
