|
A) Physical sensing
|
i) usually results from the
detection of by-products that accumulate in cells due to the uncoupling of
enzymatic or electron transfer reactions, such as the accumulation of ROS
during stress caused by too much light.
|
|
B) Biophysical sensing
|
ii) often involves the presence of
specialized proteins that have evolved to sense a particular stress; for
example, calcium channels that can sense changes in temperature and alter
Ca2+ homeostasis.
|
|
C) Metabolic sensing
|
iii) refers to modifications of
DNA or RNA structure that do not alter genetic sequences, such as the changes
in chromatin that occur during temperature stress.
|
|
D) Biochemical sensing
|
iv) refers to the mechanical
effects of stress on the plant or cell structure, for example, the
contraction of the plasma membrane from the cell wall during drought stress.
|
|
E) Epigenetic sensing
|
v) might involve changes in
protein structure or enzymatic activity, such as the inhibition of different
enzymes during heat stress.
