Project description:Investigation of whole genome gene expression level changes in a Nitrosomonas europaea (ATCC 19718) wildtype and pFur::Kan mutant [kanamycin resistance cassette insertion in the promoter region of the fur gene (NE0616)] strains grown in Fe-replete and Fe-limited media. The Nitrosomonas europaea (ATCC 19718) wiltype cells grown in Fe-limited media were compared to cells grown in Fe-replete media to gain a better understanding of the metabolic changes occurring in response to iron stress. The Nitrosomonas europaea (ATCC 19718) pFur::Kan mutant strain grown in Fe-replete & Fe-limited media were compared to wildtype cells grown in Fe=replete & Fe-limited media to gain a better understanding of the role Fur (NE0616) plays in iron homeostasis control.

A 4-plex 3 chip study using total RNA recovered from three separate wild-type cultures each of N. europaea grown in Fe-replete media and Fe-limited media and three seperate cultures each of N. europaea pFur::Kan mutant strain grown in Fe-replete and Fe-limited media. Each chip measures the expression level of 2368 genes from Nitrosomonas europaea (ATCC19718) with 4 X 72,000 60-mer 14 probe pairs per gene, with two-fold technical redundancy.

Project description:Investigation of the whole genome gene expression level changes relative to exponential phase growth in Nitrosomonas europaea ATCC19718 after 12 hours ammonia starvation, 144 hours ammonia starvation, and 20 minutes following ammonia addition to starved cells. The ammonia monooxygenase of chemolithotrophic ammonia oxidizing bacteria (AOB) catalyzes the first step in ammonia oxidation by converting ammonia to hydroxylamine. The monooxygenase of Nitrosomonas europaea is encoded by two nearly identical operon copies (amoCAB1,2). Several AOB, including N. europaea, also posess a divergent monocistronic copy of amoC (amoC3) of unknown function. Previous work suggested a possible functional role for amoC3 in N. europaea during recovery from extended ammonia starvation as part of the σE- stress response regulon during the recovery of N. europaea from extended ammonia starvation, thus indicating its importance during the exit of cells from starvation. We here used global transcription analysis to show that expression of amoC3 is part of a general post-starvation cellular response system in N. europaea. We also found that amoC3 is required for efficient exit from prolonged ammonia starvation, as deleting this gene impaired growth at elevated temperatures and recovery following starvation under high oxygen tensions. Deletion of the σ32 global stress response regulator demonstrated that the heat shock regulon also plays a significant role in mediating the recovery of N. europaea from starvation. These findings provide the first described phenotype associated with the divergent AmoC3 subunit which appears to function as a stress responsive subunit capable of maintaining ammonia oxidation activity under stress conditions. A twelve chip study using total RNA recovered from four timepoints for each of three biological replicates of wild-type cultures of Nitrosomonas europaea ATCC 19718. Total RNA was obtained from each biological culture replicate during exponential growth, following 12 hours ammonia starvation, 144 hours ammonia starvations, and 20 minutes following ammonia addition to starved cells.
