Adaptation of Plants
Plants have been exposed to the elements for thousands of years. During this time they have evolved in order to lessen the effects of abiotic stress. Signal transduction is the mechanism in plants that is responsible for the adaptation of plants (Xiong & Zhu, 2001). Many signaling transduction networks have been discovered and studied in microbial and animal systems. There is limited knowledge in the plant field because it is very difficult to find exactly which phenotypes in the plant are affected by stressors. These phenotypes are very valuable to the researchers. They need to know the phenotypes so that they can create a method to screen for mutant genes. Mutants are the key to finding signaling pathways in living creatures.
Animals and microbes easier to run tests on because they show a reaction fairly quickly when a stress factor is put on them, this leads to the isolation of the specific gene. There have been decades of research on the effects of temperature, drought, and salinity, but not very many answers. it result when scarcity of water is their

Famous quotes containing the words adaptation and/or plants:
“In youth the human body drew me and was the object of my secret and natural dreams. But body after body has taken away from me that sensual phosphorescence which my youth delighted in. Within me is no disturbing interplay now, but only the steady currents of adaptation and of sympathy.”
—Haniel Long (1888–1956)
“When the
Marne flowed by the plants nodded
And above the glistering Gila
A sunset as beautiful as the Athabasca
Stammered. The Zambezi chimed. The Oxus
Flowed somewhere.”
—John Ashbery (b. 1927)
