The changes in PsbS levels may not have induced adjustments in the overall expression of genes encoding ROS protection systems, since the systems may have been sufficiently strong to cope with the oxidative stress experienced by plants of all three genotypes during the study period.
The successful restoration of oxygen homeostasis may reduce the need for adjustments in protein expression.
This suggests that adjustments in transgene expression levels had occurred during memory cell development.
Environmental perturbations usually cause a cellular response that is characterized by adjustments in genetic expression levels and cellular physiology.
Such polar auxin transport (PAT), together with metabolic control of auxin, defines local variations in hormone levels, which are perceived and transmitted to induce hormonally controlled adjustments in gene expression and activity (Ljung, 2013; Sauer et al., 2013).
Subtle adjustments in the composition and functioning of the respiratory chain, mainly differential expression of cytochromes, were described [ 9- 11].
A justification for this approach is now clear in light of our results— clones with tight distributions are more likely to be at or near steady state and to experience only small transient adjustments in their median expression level.
Moreover adjustments in expression levels of components of primary as well as secondary metabolism, protein trafficking and turnout were apparent, highlighting the complexity of defense response.
These measurements, combined with data analysis algorithms, Reporter TF algorithm and FBA, were able to identify cellular adjustments in (a) overall expression level, (b) post-Golgi sorting, (c) amino acid biosynthesis and savaging, and (d) oxidative stress.
