Summary: Pandanus odorifer, a highly salt-tolerant plant species, exhibits mechanisms to regulate ion balance in its roots, stems, and leaves under high salt conditions. Lower levels of silicon, iron, nickel, and titanium, and higher levels of sodium, chloride, magnesium, cadmium, and chromium were found to contribute to its salt tolerance. Additionally, genes related to ion transport and homeostasis were upregulated under high salt conditions, revealing the importance of vacuolar sequestration of sodium and ion distribution in the roots and shoots of P. odorifer for salt stress tolerance.

Summary: Pandanus odorifer, an economically important species, is distributed along coasts from India and Sri Lanka to South China through tropical Asian countries. The widely used name Pandanus odoratissimus is deemed superfluous and illegitimate, prompting the designation of a neotype for Pandanus odorifer.

Summary: This review article discusses the impact of salt stress on plants and the adaptive mechanisms of plants to salt stress, including physiological, metabolic, and molecular aspects. Salinization is a global environmental issue that negatively affects crop yield and poses a threat to world food security. Conventional breeding techniques have not been very successful in developing salt tolerant plants, and the transgenic approach has provided a pathway for addressing this issue.

Summary: Soil salinization is a major cause of soil degradation, and cultivating salt-tolerant crops is an effective solution. This study investigated the salt tolerance mechanism in broomcorn millet and found that it is achieved through maintaining Na+/K+ balance and intact cell structures. Additionally, the salt-tolerant variety reshapes the rhizospheric microbial community by attracting specific beneficial microbes, which promote soil nutrient cycling and enhance stress tolerance.

Summary: Caffeic acid can improve plants' tolerance to salt stress, with more pronounced effects at a concentration of 100 μM. Wheat genotype FSD-08 shows better response to the application of caffeic acid, leading to increased growth indicators, RWC, MSI, antioxidant enzyme activities, accumulation of mineral ions in grain, and yield attributes.

Summary: The study identified multiple salt tolerance genes in Tamarix hispida through yeast expression system and high-throughput sequencing, demonstrating their reliability in enhancing plant salt tolerance. The research also observed higher expression levels of identified genes in roots under salt stress, with a significant proportion belonging to 'response to stimulus' category. The findings suggest that processes such as protein translation, osmotic adjustment, antioxidant defense, and maintenance of cellular functions play crucial roles in salt tolerance mechanisms.

Summary: In this study, the complete mitochondrial genome of a halophyte species Pandanus odorifer (Forssk.) Kuntze (Pandanaceae) was reported. The genome is circular with a length of 330,962 bp and contains 33 protein coding genes, 3 rRNAs, and 6 tRNAs. Analysis revealed the pseudogenization of important respiratory genes in the mitochondrial genome, but nuclear encoded copies were recovered. Phylogenetic analysis placed P. odorifer sister to P. tectorius.

Summary: This study evaluated salt tolerance in common vetch collections and investigated the underlying physiological mechanisms. The results showed that salt-tolerant collections of common vetch maintained lower levels of Na+ and higher levels of K+ and K+/Na+ ratio under salt stress compared to salt-sensitive ones. The expression of genes involved in Na+ and K+ transportation and redistribution was responsible for salt stress. Transcript levels of NHX7, HKT1, AKT2, and HAK17 were induced after salt stress, with higher levels in salt-tolerant collections. Proline accumulation and antioxidant defense system were also promoted in salt-tolerant collection. These findings suggest that salt tolerance in common vetch is associated with the maintenance of ion homeostasis, gene expression, proline accumulation, and antioxidant defense system.

Summary: This study investigates the composition and distribution of halophilic and salt-tolerant microbial communities in the highly saline soil of Yuncheng Salt Lake. The research finds that the dominant species and abundance of salt-tolerant microorganisms change gradually with distance from the lake. These microorganisms exhibit mechanisms of salt tolerance by regulating the expression of specific genes.

Summary: The increasing problem of soil salinization has a severe impact on soybean growth and development, leading to reduced yields and posing a serious threat to global crop production. In this study, the PfFAD3a gene was isolated from perilla and overexpressed in soybeans to assess the salt tolerance of transgenic plants. The results showed that overexpression of PfFAD3a increased the expression of PfFAD3a and the content of ff-linolenic acid in transgenic soybean plants, significantly enhancing their salt tolerance. Physiological and biochemical analysis revealed that overexpression of PfFAD3a increased the chlorophyll content and maximum photochemical efficiency of transgenic soybean plants under salt stress, while reducing the accumulation of MDA, H2O2, and O-circle(2), and increasing the activities of SOD, POD, CAT, and APX, as well as the production of proline and soluble sugar. In conclusion, the overexpression of PfFAD3a enhances salt tolerance in transgenic soybean plants through improved membrane fluidity and increased antioxidant capacity induced by C18:3.
