Working from the premise that essential genes differ in absolute requirement for growth, we describe silencing of putative essential genes in E. coli to obtain a titration of declining growth rates and transcript levels by using antisense peptide nucleic acids (PNA) and expressed antisense RNA.
The positive selection of the TMD may be related to the multicellular and more complex nature of land plants, where many different cell types likely differ in their requirements for Cu and their demand probably even changes with growth and development.
It is conceivable that different neuronal populations differ in their requirements for gene re-activation of silenced Ptet-controlled genes.
Thus peptide arrays are a useful instrument for deducing substrate consensus sequences and highly homologous kinases can differ in their requirement for phosphorylation events.
Our study shows that peptide arrays are useful for deducing substrate consensus sequences and highly homologous kinases can differ in their requirement for phosphorylation events.
Lastly, it should be noted that even in the same cellular setting, particular Gab proteins may differ in their requirement for PH domain-mediated plasma membrane recruitment.
Scrambled and control stimuli share exactly the same stimulus characteristics; however, they differ in task requirement (i.e., making a decision vs. not making a decision).
In conclusion, our data uncover two independent pathways for neuronal and synaptic loss, both triggered by A β, which already differ in their requirement for distinct types of NMDARs.
This finding has prompted van Noorden and colleagues [ 21] to propose that determinate and indeterminate nodules differ in the requirement, transport capacity or regulation of auxin transport [ 5, 21].
For example, plant species differ in their requirements for light, nutrients, and microorganisms, as well as in their ability to fend off competitors and herbivores.
