Ion content, antioxidant enzyme activity and transcriptional response under salt stress and recovery condition in the halophyte grass Aeluropus littoralis.

ABSTRACT:

Objective

In contrast to glycophytes, halophyte plants have evolved unique morphological and physiological mechanisms to deal with abiotic stress. This study presents the physiological responses of Aeluropus littoralis, a halophyte grass, to salt stress and recovery conditions on the molecular level.

Results

Elemental analysis showed that Na⁺ concentration increased in the analyzed tissue during salt stress application, and declined at recovery condition. With the exception of root tissue, comparable trends of K⁺, Ca²⁺, and Mg²⁺ concentrations were observed (decreased during salt stress, increased during recovery). Salinity led to an increase in total chlorophyll (Chl), Chl a, and carotenoids content, while Chl b content decreased.
