“…Planting two facultative halophytes, S. verrucosum and Bacopa monnieri , for 240 days reduced the electrical conductivity (EC) value from 11.13 to 7.97 dS m −1 , pH from 7.84 to 7.42, while improving soil porosity from 54.71 to 57.23%. Notably, the combined plantation of these two halophytes had a phytodesalination capacity of 1.21 T Na + ha −1 , which helped prepare the soil for Zea mays to thrive and boosted yields from 7.2 to 8.5 T ha −1 [ 141 ]. S. monoica , a salt marsh halophyte, has been shown to lower the soil EC value from 4.75 to 2.10 dS m −1 and pH from 8.40 to 6.73 [ 142 ].…”

Soil salinization, which is aggravated by climate change and inappropriate anthropogenic activities, has emerged as a serious environmental problem, threatening sustainable agriculture and future food security. Although there has been considerable progress in developing crop varieties by introducing salt tolerance-associated traits, most crop cultivars grown in saline soils still exhibit a decline in yield, necessitating the search for alternatives. Halophytes, with their intrinsic salt tolerance characteristics, are known to have great potential in rehabilitating salt-contaminated soils to support plant growth in saline soils by employing various strategies, including phytoremediation. In addition, the recent identification and characterization of salt tolerance-related genes encoding signaling components from halophytes, which are naturally grown under high salinity, have paved the way for the development of transgenic crops with improved salt tolerance. In this review, we aim to provide a comprehensive update on salinity-induced negative effects on soils and plants, including alterations of physicochemical properties in soils, and changes in physiological and biochemical processes and ion disparities in plants. We also review the physiological and biochemical adaptation strategies that help halophytes grow and survive in salinity-affected areas. Furthermore, we illustrate the halophyte-mediated phytoremediation process in salinity-affected areas, as well as their potential impacts on soil properties. Importantly, based on the recent findings on salt tolerance mechanisms in halophytes, we also comprehensively discuss the potential of improving salt tolerance in crop plants by introducing candidate genes related to antiporters, ion transporters, antioxidants, and defense proteins from halophytes for conserving sustainable agriculture in salinity-prone areas.

“…Lo anterior puede deberse a que la concentración óptima de AIB varía de acuerdo con las especies y el nivel endógeno de fitohormonas que se hallan presentes en las plantas madre durante la realización de los esquejes (Cabahug et al, 2018). Recientemente, se reportó que, en el municipio de Villamar, Michoacán, México, crece una especie halófita nativa perenne con enorme potencial fitodesalinizador llamada Sesuvium verrucosum al bioacumular 0.96 t ha -1 de Na + (Lastiri-Hernández et al, 2020), una dicotiledónea de la familia Aizoaceae con fotosíntesis C3, la cual posee una amplia plasticidad fenotípica debido a la formación de cambios sucesivos que ha desarrollado esta especie en su sistema ontogenético, como son los patrones de engrosamiento secundario y la formación del floema interno, mismos que le permiten contar con una mayor resistencia mecánica, flexibilidad y sobre todo, una mayor capacidad de almacenamiento de agua y cationes, principalmente Na + (Elbar, 2015).…”

La sequía y la salinidad son condiciones de algunos suelos que limitan la producción agrícola a nivel mundial. Para combatir estos efectos, se ha hecho énfasis en una técnica llamada fitodesalinización, la cual consiste en el uso de especies halófitas con la capacidad para extraer cantidades importantes de sodio (Na+) del medio afectado. Sin embargo, ésta es una práctica agrícola que demanda una gran cantidad de material vegetal por hectárea, lo cual dificulta su implementación en los sistemas productivos con problemas de salinidad. El objetivo de este trabajo fue determinar la capacidad de enraizamiento de los esquejes de la especie halófita S. verrucosum y analizar los cambios de magnitud en sus parámetros biométricos, a partir de diferentes concentraciones en el tratamiento hormonal, en un periodo de 90 días. Para el desarrollo del experimento se utilizó un diseño experimental completamente al azar y se consideraron dos factores: las concentraciones del ácido indol butírico (AIB) (0, 800, 1 200, 1 600, 2 000 y 4 000 mg L-1) y la posición de los esquejes (basal-intermedia e intermedia-apical). Los resultados obtenidos demostraron diferencias significativas entre los diferentes tratamientos. Los esquejes de la porción intermedia-apical fueron los que obtuvieron el mayor porcentaje de enraizamiento, número de raíces, peso fresco y seco, tanto de la raíz como de la parte área de la planta, diámetro del tallo y altura de la planta, principalmente a una concentración de 2 000 mg L-1. A través de este método, es posible implementar la fitodesalinización de manera extensiva.

“…In addition, it has been widely used for environmental protection, such as sand dune fixation, desert greenification, and landscaping [ 16 ]. A recent study showed the benefit of using the salt-tolerant nature of S. verrucosum for rapid phytodesalination of saline soil to promote the growth of glycophyte Zea mays [ 17 ].…”

Owing to their sessile nature, plants have developed a tapestry of molecular and physiological mechanisms to overcome diverse environmental challenges, including abiotic stresses. Adaptive radiation in certain lineages, such as Aizoaceae, enable their success in colonizing arid regions and is driven by evolutionary selection. Sesuvium verrucosum (commonly known as Western sea-purslane) is a highly salt-tolerant succulent halophyte belonging to the Aizoaceae family; thus, it provides us with the model-platform for studying plant adaptation to salt stress. Various transcriptional and translational mechanisms are employed by plants to cope with salt stress. One of the systems, namely, ubiquitin-mediated post-translational modification, plays a vital role in plant tolerance to abiotic stress and other biological process. E3 ligase plays a central role in target recognition and protein specificity in ubiquitin-mediated protein degradation. Here, we characterize E3 ligases in Sesuvium verrucosum from transcriptome analysis of roots in response to salinity stress. Our de novo transcriptome assembly results in 131,454 transcripts, and the completeness of transcriptome was confirmed by BUSCO analysis (99.3% of predicted plant-specific ortholog genes). Positive selection analysis shows 101 gene families under selection; these families are enriched for abiotic stress (e.g., osmotic and salt) responses and proteasomal ubiquitin-dependent protein catabolic processes. In total, 433 E3 ligase transcripts were identified in S. verrucosum; among these transcripts, single RING-type classes were more abundant compared to multi-subunit RING-type E3 ligases. Additionally, we compared the number of single RING-finger E3 ligases with ten different plant species, which confirmed the abundance of single RING-type E3 ligases in different plant species. In addition, differential expression analysis showed significant changes in 13 single RING-type E3 ligases (p-value < 0.05) under salinity stress. Furthermore, the functions of the selected E3 ligases genes (12 genes) were confirmed by yeast assay. Among them, nine genes conferred salt tolerance in transgenic yeast. This functional assay supports the possible involvement of these E3 ligase in salinity stress. Our results lay a foundation for translational research in glycophytes to develop stress tolerant crops.
