Project description:The ability of the Antarctic microarthropod, Cryptopygus antarcticus (Collembola, Isotomidae), to survive low temperatures has been well studied at the physiological level. These investigations have indicated the importance of the moulting process in conferring this ability. This study investigated gene expression in groups of C. antarcticus that have distinct differences in their ability to survive low temperatures. A microarray containing 5,400 C. antarcticus expressed sequence tags was used to investigate gene expression differences between groups of animals with different supercooling points (SCP), and to low temperatures close to their SCP. By demonstrating the involvement of moulting genes in the differential survival of two groups of C. antarcticus with distinct SCPs, the results of this investigation add support to the role moulting plays in conferring cold tolerance in C. antarcticus.
Project description:Purpose： The goal of this study is compare the effect of glnA gene in curdlan synthesis in Agrobacterium sp. CGMCC 11546. methods: The transcriptional and metabolomics analysis the function of glnA in Agrobacterium sp. CGMCC 11546. Results: The transcriptional and metabolomics showed that the decrease of curdlan production in the ΔglnA mutants may be caused by the insufficient supply of energy ATP conclusion: glnA play an important role in curdlan synthesis in Agrobacterium sp. CGMCC 11546
Project description:Purpose： The goal of this study is compare the effect of phbC gene in curdlan synthesis in Agrobacterium sp. CGMCC 11546. methods: The transcriptional and metabolomics analysis the function of phbC in Agrobacterium sp. CGMCC 11546. Results:The transcriptional and metabolomics showed that the decrease of curdlan production in the ΔphbC mutants may be caused by the insufficient supply of energy ATP conclusion:phbC play an important role in curdlan synthesis in Agrobacterium sp. CGMCC 11546
Project description:Purpose: The goal of this study is compare the effect of MetH and MetZ gene in curdlan synthesis in Agrobacterium sp. CGMCC 11546. methods: The transcriptional and metabolomics analysis the function of metH and metZ in Agrobacterium sp. CGMCC 11546. Results: The transcriptional and metabolomics showed that the decrease of curdlan production in the ΔmetH and ΔmetZ mutants may be caused by the insufficient supply of energy ATP conclusion: MetH and MetZ play an important role in curdlan synthesis in Agrobacterium sp. CGMCC 11546
