Underlying Mechanisms of Action to Improve Plant Growth and Fruit Quality in Crops under Alkaline Stress
The high content of carbonates (CO32−), bicarbonate (HCO3−), and high pH (>7.5) causes environmental pressure and alkaline stress, impairs plant growth and development, and limits fruit quality by causing osmotic alterations and hindering nutrient absorption. Because of alkaline stress, plants are i...

| Sumario: | The high content of carbonates (CO32−), bicarbonate (HCO3−), and high pH (>7.5) causes environmental pressure and alkaline stress, impairs plant growth and development, and limits fruit quality by causing osmotic alterations and hindering nutrient absorption. Because of alkaline stress, plants are in an oxidative environment that alters their metabolic processes, impairing their growth, development, and fruit quality. In response to this situation, plants use several mechanisms to cope, including the alteration of osmolytes, induction of transcription factors, signal transduction, hormone synthesis, alteration of the antioxidant system, and differential gene expression. Current knowledge and understanding of the underlying mechanisms that promote alkalinity tolerance in crops may lead to new production strategies to improve crop quality under these conditions, while ensuring food security. |
