“…As 25 differentially expressed TFs were detected in all three tissues (Figure 9A), we then analyzed the expression changes of these TFs, and found that only 2 members (MYB59 and bHLH101) in roots, leaf sheaths and leaf blades were downregulated, while other 23 members in all tissues were upregulated (Figure 9B). Moreover, the log2 ratio of NAC25, bZIP60 and HSF C-2a in roots, leaf sheaths and leaf blades were > 3 (meaning that the transcripts of these genes increased more than 2 3 folds after NaCl treatment, Figure 9B), indicated that these TFs might play key roles in the salt tolerance of sweet sorghum.…”

“…The cultivation of sweet sorghum in large-scale salinized areas is thought to be a promising approach to ensure food security and promote ecological restoration [2,3]. For this purpose, the strong photosynthetic ability of sweet sorghum under saline environments could (i) provide large amounts of resources (leaves and stalks) for producing of silage and hay; (ii) develop roots and shoots for sand fixation and soil reservation and, (iii) accumulate sugars for energy production.…”

Sweet sorghum is an important bioenergy grass and valuable forage with a strong adaptability to saline environments. However, little is known about the mechanisms of sweet sorghum coping with ion toxicity under salt stresses. Here, we first evaluated the salt tolerance of a sweet sorghum cultivar “Lvjuren” and determined its ion accumulation traits under NaCl treatments; then explored key genes involved in Na+, Cl−, K+ and NO3− transport using transcriptome profiling and qRT-PCR method. The results showed that the growth and photosynthesis of sweet sorghum were unaffected by 50 and 100 mM NaCl treatments, indicative of a strong tolerance of this species to salt stresses. Under NaCl treatments, sweet sorghum could efficiently exclude Na+ from shoots and accumulate Cl− in leaf sheaths to avoid their overaccumulation in leaf blades; meanwhile, it possessed a prominent ability to sustain NO3− homeostasis in leaf blades. Transcriptome profiling identified several differentially expressed genes associated with Na+, Cl−, K+ and NO3− transport in roots, leaf sheaths and leaf blades of sweet sorghum after 200 mM NaCl treatment for 6 and 48 h. Moreover, transcriptome data and qRT-PCR results indicated that HKT1;5, CLCc and NPF7.3-1 should be key genes involved in Na+ retention in roots, Cl− accumulation in leaf sheaths and maintenance of NO3− homeostasis in leaf blades, respectively. Many TFs were also identified after NaCl treatment, which should play important regulatory roles in salt tolerance of sweet sorghum. This work lays a preliminary foundation for clarifying the molecular basis underlying the adaptation of sweet sorghum to adverse environments.

“…There are exceeding 1 billion ha lands affected by salinity worldwide [ 2 ]. In China, approximately 30 percent of the total 3.6 × 10 7 ha salt-affected lands are potentially arable [ 3 ]. Therefore, with population expansion, urban spread and climate change, the use of salinized lands to cultivate crops and forages is an important strategy to ensure food security and promote ecological restoration [ 4 ].…”

“…Furthermore, different from traditional crop species, sweet sorghum can adapt well to various environmental stresses including salinity, drought and flood, serving as a pioneer plant for recovering saline and marginal lands [ 5 , 9 ]. Combining these eminent traits, there have been increasing practices to evaluate field performance of sweet sorghum in salt-affected lands in China [ 2 , 3 ]. Thus, understanding of mechanisms employed by sweet sorghum to adapt to adverse environments will lay a theoretical basis for the large-scale cultivation of this species in salinized areas.…”

In addition, GO analysis identified candidate genes involved in maintaining membrane stability and photosynthetic capacity under salt stresses. This work lays a preliminary foundation for clarifying the molecular basis underlying the adaptation of sweet sorghum to adverse environments.
