In fatal stage, Fl concentration or accumulation leads to alternation in growth, cell differentiation, and sub cellular organization in brain cells (Madhusudhan et al., 2009).
Both microgravity conditions in space and simulated microgravity using a 3-dimensional clinostat resulted in: (1) automorphosis of etiolated pea seedlings, (2) epicotyls bending ca. 45° from the vertical line to the direction away from cotyledons, (3) inhibition of hook formation and (4) alternation of growth direction of roots.
The increased amino acid replacement in rbcL may reflect the adaptive fine-tuning of RuBisCO in the alternation of growth forms (heterophyllous or homophyllous) and nuclear genome setsz.
This fast alternation of growth and depolymerization phases, termed dynamic instability [ 62], leads to highly dynamic changes observed for MTs in vitro and in vivo.
Earlier studies in Arabidopsis have revealed that BABA treatment alters amino acid composition and can be linked to an amino acid associated alternation of growth [ 10, 11].
This alternation compared to growth medium should also affect cellular metabolism.
For instance in the top left panel of Figure 5a, the R1 mode score varies regularly between positive and negative values, indicating a periodic alternation in the growth cone shape between bending left and bending right.
Consequently the alternations of the growth rate and genetic mutations may create a suitable environment to loose cellular restriction to viral propagation.
Expansion and contraction of seasonal wetlands induce a sequential alternation between rapid biomass growth and concentration, creating the conditions for local stranding of small fish as they move in response to varying water levels.
But to get more closely at Aristotle's original usage, he had to expand the meaning of motion to cover a much broader range of phenomena that include various other sorts of change, such as growth and diminution, alternation, and generation and corruption, making an objects motion in space (displacement or 'locomotion') just a special case of motion.
