5-FOA resistant colonies were tested for
auxotrophy by patching on CD medium and CD medium with uracil and uridine.
The genome of th17 cell-inducing segmented filamentous bacteria reveals extensive
auxotrophy and adaptations to the intestinal environment.
fischeri strain ESR1, that the host squid provides certain amino acids to support the bacteria, and
auxotrophy for amino acids in the bacteria can lower the level of its colonization of the squid light organ.
Repression of cystathionine [Gamma]-synthase in Arabidopsis thaliana produces partial methionine
auxotrophy and developmental abnormalities.
To characterize the phenotypes of the DNA photolyase-deficient strain DP-1 ([DELTA]pyrE [DELTA]suaI [DELTA]phr) and argD deletion mutant SK-5 ([DELTA]pyrE [DELTA]suaI [DELTA]argD), UV sensitivity and agmatine
auxotrophy were examined, respectively.
The inactivation of URA3 results in uracil
auxotrophy and 5-fluoroorotic acid resistance phenotype (11).
MIPS regulatory loci have not yet been identified in higher plant species; however, at least 10 different Ins
auxotrophy genes have been identified in yeast (Culbertson and Henry, 1975), albeit several of these have pleiotropic effects on carbon source utilization.
