Resumen

Los polímeros superabsorbentes (SAPs) pueden ayudar a la germinación del maíz bajo sequía, pero la eficacia varía. El SAP MERCK mejoró el crecimiento de las plántulas, mientras que el SWT mostró fitotoxicidad, lo que resalta la necesidad de una selección cuidadosa y el análisis de marcadores moleculares para la resiliencia al estrés.

Conclusiones:

La eficacia de los SAPs para mitigar el estrés por sequía en maíz depende de la formulación, y MERCK muestra potencial y SWT demuestra potencial fitotóxico.
Los genes identificados diferencialmente expresados proporcionan información mecanicista sobre las respuestas fisiológicas y sirven como biomarcadores potenciales para el mejoramiento de cultivares de maíz resistentes al estrés.
Este estudio ofrece una evaluación multinivel de los SAPs, guiando futuras aplicaciones en recubrimientos de semillas y programas de mejoramiento de maíz para una mayor tolerancia a la sequía.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Regulation of Transpiration by Stomata

Regulation of Transpiration by Stomata

During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
