Abiotic stress response

In plants, DREB/ERF and AP2/ERF subfamily of ethylene-responsive element (GCC box)-binding transcription factors function in the regulation of abiotic stress responses and regulate disease resistance. AP2/ERF members are downstream components of both ethylene and JA signaling pathways, and are key to the...

In recent years, it has become evident that microRNAs (miRs) play a significant role in the regulation of plant development [45-51], biotic and abiotic stress response and, in a few cases, central (primary) metabolism [52-58]. Expression of miR target genes could be reduced by overexpressing the corresponding miRs, or ele-...

Effect on content of polyphenolic compounds Complete protection from stress, however, appears to reduce plant synthesis of polyphenolic compounds, which are known to be produced as part of the plant s inducible resistance response to fungal and pest attack, but are also produced in response to certain abiotic stress factors such as mechanical injury (Feucht and Treutter, 1999). 

Plants have the innate capacity, gained over eons of evolution, to actively respond to biotic and abiotic stresses in their environment. Many of the stresses that occur naturally are frequently mimicked by the operations that constitute the cultivation, harvesting, marketing, and consumption of fruits and vegetables. Metabolic responses induced by stress and that are adaptive in nature can result in reduced product quality.

Ethylene is involved in most of the plant defensive responses against abiotic stresses. Its action can vary depending on the kind of stress. Some examples of ethylene involvement in response to abiotic stress are presented below.

Plants are highly adaptable to stresses (Levitt 1980,1990). Plant cells, in response to abiotic stresses, can synthesize specific proteins, which alleviate stress by eliminating or neutralizing its effects, but which can also protect basic cellular structures and metabolic processes (Levitt 1980, 1990). Protein synthesis which occurs under the effect of a stress factor has been observed in many plants. The role of such proteins has not been elucidated completely, but in all likelihood they are defense and repair proteins.

To increase production and facilitate isolation, plant cells have been immobilised on various matrices such as polyurethane foam and calcium alginate gel beads,24 while elicitation (i.e. the induction of a defence response) is generally critical for the production of secondary metabolites. The rationale for the use of elicitors is that plants produce secondary metabolites as part of a defence response to stress, either biotic (pathogen infection) or abiotic (ultraviolet, toxic heavy metals and rare earth ions). Jasmonic acid plays a crucial role in plant stress responses and, along with fungal polysaccharides and heavy metals, is the most widely employed elicitor in plant tissue cultures.30...
