TranscriptomicsTwo transcription factors are necessary for iron homeostasis in a salt-dwelling archaeon [ChIP-chip data]
Because iron toxicity and deficiency are equally life threatening, maintaining intracellular iron levels within a narrow optimal range is critical for nearly all known organisms. However, regulatory mechanisms that establish homeostasis are not well understood in organisms that dwell in environments...

TranscriptomicsRosR is a haloarchaeal-specific transcription factor required for the response to extreme oxidative stress in Halobacterium salinarum NRC-1.
Previous work has shown that the hypersaline-adapted archaeon, Halobacterium salinarum NRC-1, is highly resistant to oxidative stress caused by exposure to hydrogen peroxide, UV and gamma radiation. Genome-wide dynamics alteration of gene the GRN has been implicated in such resistance. However, the...

MetabolomicsMetabolomic homeostasis shifts after callus formation and shoot regeneration in tomato
Plants can regenerate from a variety of tissues on culturing in appropriate media. However, the metabolic shifts involved in callus formation and shoot regeneration are largely unknown. The metabolic profiles of callus generated from tomato (Solanum lycopersicum) cotyledons and that of shoot regener...

TranscriptomicsA single functional blast resistance gene Pi54 activates complex defense mechanism in Rice
To investigate the responses of resistance gene Pi54 at transcriptome level in blast resistant transgenic rice line TP-Pi54 during infection by Magnaporthe oryzae, we studied the co-expression analysis using microarray along with susceptible non-transgenic line Taipei 309 (TP). Suitable controls ...

TranscriptomicsA regulatory hierarchy controls the dynamic transcriptional response to extreme oxidative stress in archaea.
Previous work identified the winged helix-turn-helix DNA binding transcription factor (TF) RosR (encoded by VNG0258H gene), which dynamically regulates expression of more than 300 genes in response to oxidative stress in Halobacterium salinarum (Sharma 2012). RosR is required for survival of oxidant...
