“…Then Na + and Cl − are over-accumulated inside the plants which would affect their growth and development (Gao et al 2022). Plants usually alleviate the effects of salt stress through the excretion of excess ions outside the body or compartmentalization of ions into the vacuoles under the regulation of salt stressresponsive genes, especially for the salt tolerance gene (Adillah et al 2022;Theerawitaya et al 2019).…”

The DUF1644 family is a highly conserved and functionally unknown protein family and has been demonstrated significantly improved the salt tolerance of rice (nonhalophytes). However, little is understood about the function of the DUF1644 gene in halophytes. Further studies are required to determine whether it has a similar function in halophyte species. In our study, the functions of ZmDUF1644 from halophyte Zoysia matrella Z123 species were investigated under salt stress. Phylogenetic analysis clustered ZmDUF1644 and OsSDIP361 in the same group, which function as a salttolerant genes in rice. Our experimental data suggested that the ZmDUF1644 gene significantly alleviated the growth inhibition of transgenic Arabidopsis thaliana seedlings caused by salt stress. The maximum root length, fresh weight, and photosynthetic pigment content of transgenic seedlings were obviously better than that of the wild type. Moreover, a relatively lower relative electrolyte leakage rate, toxic ion (Na + ) content, and Na + /K + ratios were also found in the transgenic line when compared with the wild type under salt stress. In conclusion, this study revealed that the ZmDUF1644 gene was overexpressed in Arabidopsis thaliana significantly enhancing the salt tolerance of seedlings. It is the first report on the functions of ZmDUF1644 from halophyte Zoysia matrella which has a similar function in halophyte species.

We studied changes in plant growth, nutrient absorption, quality of fresh leaves, and the antioxidant enzyme systems of leaves treated with AMF (Glomus etunicatum) in tea (tea cultivar “Xinyang 10”) seedlings exposed to 0 and 100 mmol/L sodium chloride (NaCl). The AMF colonization in the tea roots decreased observably by 50.1% after a 5-week soil NaCl (100 mmol/L) treatment. The growth, leaf nutrient levels, and leaf quality parameter contents significantly declined by 18%–39% in the 100 mmol/L NaCl treatments. In contrast, these variables exhibited observably higher responses in the mycorrhizal seedlings than in the nonmycorrhizal seedlings. Furthermore, AMF improved the leaves’ total amino acid concentrations dramatically, accompanied by the upregulation of the genes of the amino acid synthetic enzymes, such as glutamate dehydrogenase (CsGDH), glutamate synthase (CsGOGAT), and glutamine synthetase (CsGS), while 100 mmol/L NaCl seedlings represented a negative performance. In addition, the 100 mmol/L NaCl treatments dramatically downregulated the expression level of the tea caffeine synthase 1 gene (CsTCS1), the ascorbate peroxidase gene (CsAPX), and the 3-hydroxy-3-methylglutaryl coenzyme gene (CsHMGR) in the leaves, while the AMF seedlings represented positive performances. These results suggest that AMF may play an active role in fresh leaf quality via the partial upregulation of the relevant genes’ expression. In contrast, salt stress represented the opposite result in tea. The seedlings inoculated with AMF showed significantly increased antioxidant enzyme activities, by 13.3%–19.6%, including peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD), over the non-AMF inoculated tea seedlings. Still, they did not affect glutathione reductase (GR), irrespective of the NaCl condition. Further studies indicated that AMF observably upregulated the genes’ expressions (i.e., CsCAT and CsSOD) in both the 0 and 100 mmol/L NaCl seedlings. Meanwhile, the 100 mmol/L NaCl seedlings represented markedly lower antioxidant enzyme activities (i.e., SOD, CAT, and POD) and gene expressions (i.e., CsSOD and CsCAT) than the non-NaCl seedlings, irrespective of AMF inoculation. These results imply that AMF has a positive role in strengthening salt tolerance and on the quality of fresh tea leaves.
