Expression during growth in stringent medium was also remarkable for numerous tested transcripts.
A selection of 26 transcripts of interest dispersed along the intergenic regions was assessed for expression changes in the presence of various stress conditions including pH, temperature, oxidative shocks and growth in a stringent medium.
Cultures were performed in the presence of 1 mM of paraquat (Sigma) for 30 minutes, or grown in the stringent medium NZM (10 g/l casein tryptone digested, Fluka 95039; 5 g/l NaCl; 2 g/l MgSO4 7H20; pH 7.0).
The selected cutoff of 1.00E−04 (false positive rate of 11%) which is a medium stringent significance filter was implemented based on our experience with miRNA array profiling, biological knowledge and the genomic context of miRNAs.
Additionally, two sets of less stringent C values (medium confidence: 2.6, 1.6, 2.4, and, low confidence: 2.4, 1.4, 2.2 for column, plate and row pools, respectively) were used to anchor additional contigs at the same p-value.
This was further validated by the use of a yeast two-hybrid system that confirmed the interaction of wild-type PfI2 with PfPP1c and suggested that it was strong since the mated PfI2 and PfPP1 yeast strains were able to grow under stringent conditions (SD-LWHA medium).
Therefore, to ensure both good representativeness and low redundancy and, at the same time, to mitigate the risk that reads derived from paralogous sequences are assembled together into one contig, we chose the medium stringent 80 MMP as assembly parameter for the sweetpotato gene index.
However, the unique characteristics of nowadays MHWN, such as distributed and dynamic network architecture, broadcast nature of wireless medium and stringent resource constraints of wireless devices, makes it extremely attractive and vulnerable to malicious attacks.
However, the unique characteristics of MHWN, such as distributed and dynamic network architecture, broadcast nature of wireless medium and stringent resource constraints of wireless devices, make it subject to interference from other nearby communication system, malicious jammers, and other sources of noise.
Homologous recombinants were selected on stringent hypoxanthine aminopterin-thymidine-supplemented medium.
Even under the most stringent feeder-free conditions without conditioned medium, human ESC exhibited an undifferentiated morphology, expressed markers of undifferentiated cells, demonstrated high alkaline phosphatase activity and multilineage differentiation and retained a normal karyotype.
