Background: Plant growth and development are severely affected by soil salinity. This study was carried out to evaluate the interaction of foliar application of antioxidants (β-carotene and gallic acid) and salt stress on Lepidium sativum seedlings.
Results: Our findings revealed that total dry and fresh weight were adversely affected by 25 mM NaCl salinity stress. Moreover, K content decreased while Na content increased significantly. The foliar application of β-carotene and gallic acid significantly mitigated the effects of salt stress by regulating ion uptake, reducing HO and malondialdehyde (MDA) content, as well as increasing enzymatic antioxidant activity, phenolic, glutathione, and chlorophyll content.
Conclusions: β-carotene- and gallic acid-treated plants had higher salt tolerance.

Introduction: Melatonin significantly enhances the tolerance of plants to biotic and abiotic stress, and plays an important role in plant resistance to salt stress. However, its role and molecular mechanisms in eggplant salt stress resistance have been rarely reported. In previous studies, we experimentally demonstrated that melatonin can enhance the salt stress resistance of eggplants.

Background: RNA m6A methylation installed by RNA methyltransferases plays a crucial role in regulating plant growth and development and environmental stress responses. However, the underlying molecular mechanisms of m6A methylation involved in seed germination and stress responses are largely unknown. In the present study, we surveyed global m6A methylation in rice seed germination under salt stress and the control (no stress) using an osmta1 mutant and its wild type.

Rheum tanguticum, an endemic species from the Qinghai-Xizang Plateau, is a significant perennial and medicinal plant recognized for its robust resistance to abiotic stresses, including drought, cold, and salinity. To advance the understanding of stress-response mechanisms in R. tanguticum, this study aimed to establish a reliable set of housekeeping genes as references for normalizing RT-qPCR gene expression analyses.

Guava is a fruit crop widely exploited in the Northeast region of Brazil. However, its exploitation is limited by water scarcity and, in many cases, producers are forced to use water with high levels of salts in irrigation. Thus, it is necessary to develop techniques to induce plant tolerance to salt stress, and the foliar application of a non-enzymatic compound such as ascorbic acid is a promising alternative to mitigate the deleterious effects on plants.

Background: The Sec14 domain is an ancient lipid-binding domain that evolved from yeast Sec14p and performs complex lipid-mediated regulatory functions in subcellular organelles and intracellular traffic. The Sec14 family is characterized by a highly conserved Sec14 domain, and is ubiquitously expressed in all eukaryotic cells and has diverse functions. However, the number and characteristics of Sec14 homologous genes in soybean, as well as their potential roles, remain understudied.
