This is unusual for a gene involved in the nutrient remobilization phase of senescence.
Perhaps more surprising is the fact that the very rapid senescence programme of ephemeral flowers also involves a nutrient remobilization phase.
Transcript abundance increases during perianth senescence, supporting a role for this nitrate transporter in the nutrient remobilization phase of flower senescence (Hunter et al. 2002).
While excellent studies of senescence have been conducted in these systems, we must interpret these results with caution when it comes to the nutrient remobilization phase of senescence.
McCook, L. J. Macroalgae, nutrients and phase shifts on coral reefs: scientific issues and management consequences for the Great Barrier Reef.
Virulence gene expression of Y. pestis is tightly regulated by environment signals, including temperature, nutrients, growth phase, osmolarity and pH.
To elucidate the food composition necessary for dietary entrainment, we examined whether complete or partial substitution of dietary nutrients affected phase shifts in liver clocks of mice.
Together, these experiments suggest that there are two phases during medulla development that are differentially sensitive to dietary nutrients: an early phase that requires dietary nutrients to activate and sustain NE expansion, and a later phase that can sustain neural proliferation and convert NE cells to NBs without dietary inputs.
Other factors influencing PUFA content suggested are CO2 concentration, nutrient availability, growth phase and day-night rhythm (Mayzaud et al. 1990;Yonmanitchai and Ward 1991;Zhukova 2004 Meiser et al. 2004 Lv et al. 2010).
For simulating anaerobic and starvation conditions that exist within the nematode, the saturated bacterial cultures were incubated for further 30 days at 25°C in sealed tubes without disturbance to reach a nutrient depleted stationary phase as described previously [47], [48].
