| molecular cloning of full-length cdna encoding delta-9 desaturase through pcr strategies and its genomic organization and expression in grass carp (ctenopharyngodon idella). | desaturases are enzymes that catalyze double bond formation in fatty acids, which is a critical step in the synthesis of unsaturated fatty acids in organisms. desaturase cdna has been cloned from various species. here we report the cloning of a full-length cdna of delta(9)-desaturase from grass carp (ctenopharyngodon idella), using a combination of pcr techniques: reverse transcription-polymerase chain reaction (rt-pcr) and rapid amplification of cdna ends (race). the resolved cdna encompasses 2 ... | 2001 | 11170264 |
| toxic and feeding deterrent effects of native aquatic macrophytes on exotic grass carp (ctenopharyngodon idella). | declines of amphibians have been attributed to many factors including habitat degradation. the introduction of grass carp (ctenopharyngodon idella) as a biological agent for aquatic plant control in ponds and lakes managed narrowly for human recreation has likely contributed to amphibian declines through massive plant removal and associated habitat simplification and thus degradation. this research examined the interactions among grass carp and three midwestern aquatic plants (jussiaea repens, r ... | 2002 | 12211697 |
