“…These short-lived nuclear proteins can help plants sense and respond to changes in auxin levels quickly [70]. Overexpression of Aux/IAA genes can improve salt tolerance, such as grapevine VvIAA18 gene [71]. We also observed cessation of plant growth when they were treated with NaCl, and such findings were consistent with auxin-mediated regulation in plants.…”

As one of the most severe environmental stresses, salt stress can cause a series of changes in plants. In salt tolerant plant Zoysia macrostachya, germination, physiology, and genetic variation under salinity have been studied previously, and the morphology and distribution of salt glands have been clarified. However, no study has investigated the transcriptome of such species under salt stress. In the present study, we compared transcriptome of Z. macrostachya under normal conditions and salt stress (300 mmol/L NaCl, 24 h) aimed to identify transcriptome responses and molecular mechanisms under salt stress in Z. macrostachya. A total of 8703 differently expressed genes (DEGs) were identified, including 4903 up-regulated and 3800 down-regulated ones. Moreover, a series of molecular processes were identified by Gene Ontology (GO) analysis, and these processes were suggested to be closely related to salt tolerance in Z. macrostachya. The identified DEGs concentrated on regulating plant growth via plant hormone signal transduction, maintaining ion homeostasis via salt secretion and osmoregulatory substance accumulation and preventing oxidative damage via increasing the activity of ROS (reactive oxygen species) scavenging system. These changes may be the most important responses of Z. macrostachya under salt stress. Some key genes related to salt stress were identified meanwhile. Collectively, our findings provided valuable insights into the molecular mechanisms and genetic underpinnings of salt tolerance in Z. macrostachya.

“…The gene ERF76 that encodes salt-responsive ERF TF in poplar was overexpressed in transgenic tobacco and resulted in improved salt tolerance ( Yao et al, 2016 ). Similarly, salt tolerance in tobacco was increased by overexpression of VvIAA18 from grapevine ( Li et al, 2020 ). Xie et al (2018) reported that 75 TFs distributed among 10 families (NAC, AP2/ERF, GATA, MYB, bZIP, bHLH, CBF, ZFP, WRKY and SPL TF) were differentially expressed in maize under salt stress ( Xie et al, 2018 ).…”

Salt stress affects crop yield by limiting growth and delaying development. In this study, we constructed 16 transcriptome libraries from maize seedling roots using two maize lines, with contrasting salt tolerance, that were exposed to salt stress for 0, 6, 18 and 36 h. In total, 6,584 differential expression genes (DEGs; 3,669 upregulated, 2,915 downregulated) were induced in the salt-sensitive line and 6,419 DEGs (3,876 upregulated, 2,543 downregulated) were induced in the salt-tolerant line. Several DEGs common to both lines were enriched in the ABA signaling pathway, which was presumed to coordinate the process of maize salt response. A total of 459 DEGs were specifically induced in the salt-tolerant line and represented candidate genes responsible for high salt-tolerance. Expression pattern analysis for these DEGs indicated that the period between 0 and 6 h was a crucial period for the rapid response of the tolerant genes under salt stress. Among these DEGs, several genes, Aux/IAA, SAUR, and CBL-interacting kinase have been reported to regulate salt tolerance. In addition, the transcription factors WRKY, bZIP and MYB acted as regulators in the salt-responsive regulatory network of maize roots. Our findings will contribute to understanding of the mechanism on salt response and provide references for functional gene revelation in plants.

“…Genetic manipulation techniques would aid towards understanding grapevine gene function; however, the production of grapevine transgenic plants is slow and laborious at present (Vidal et al 2010), thus functional studies of grapevine genes, often involves cloning them into other species, such as tobacco ( Nicotiana spp.) and/or Arabidopsis thaliana (Bogs et al 2007, Henderson et al 2015, Li et al 2020a). Traditionally, the contribution of candidate genes to salt tolerance in grapevine is assessed by comparing their expression between cultivars with different degrees of tolerance; however, this approach is only correlative and does not take into account additional genotypic variation that contributes towards salt tolerance mechanisms.…”

Salinity, which is predominantly an issue for agricultural systems in arid and semi-arid regions, has the potential to impair grape production and wine quality, and its impact on the grape and wine industries is predicted to increase with climate change. Research on the physiological and molecular changes that occur in salt-affected vines has unveiled complex osmotic and ionic responses that include oxidative stress, water loss, photoinhibition, growth inhibition and necrosis. Proposed salt tolerance mechanisms include elevated antioxidant production, hydric regulation and salt exclusion from shoots and berries. These later of these mechanisms is found in certain Vitis genotypes that, when grafted as rootstocks, can protect fruit-bearing scions from accumulating significant amounts of saline ions from soils, most notably through the presence of specific transport proteins that are involved in regulating the transfer of ions from root to shoot via the xylem. Significant gaps in knowledge remain, however, regarding salt tolerance mechanisms for Vitis species, with many mechanisms inferred from other species or documented only at the level of gene expression. A better understanding of the mechanisms that confer salt tolerance in Vitis species is needed to improve the production of new germplasm that is locally adapted and better suited to the challenges of a changing climate. Hence, this review covers the current knowledge on the characteristics that are associated with salt damage and tolerance in grapevine cultivars and rootstocks and highlights possible future avenues that will enable development of new options for the industry to combat salinity.
