“…A comparison between the northern variety of QY2 and the southern variety of NY1 indicated that the ABA content in the tuber of QY2 was higher [26]. The microbial community in the root of the crops could also play an important role under salt stress [27,28]. With the development of research on the abiotic stress of Jerusalem artichoke, the stress resistance of Jerusalem artichoke has been widely recognized.…”

Background: Jerusalem artichoke (Helianthus tuberosus L.) is strongly resistant to stress and an important plant used for ecological management in northern China in recent years. Currently, Jerusalem artichoke has been widely planted in the area around Qinghai Lake in Qinghai Province, China. Jerusalem artichoke can not only prevent land desertification but also has maintain most of its level of production. However, there is little research on the mechanism of drought resistance of Jerusalem artichoke.Results: We conducted transcriptome sequencing under drought stress and normal watering treatment for two varieties, QY1 and QY3, with differing degrees of drought tolerance. In the three stress periods of QY1 and QY3, 5,613, 12,985 and 24,923 differentially expressed genes (DEGs) were identified, respectively. GO analysis showed that there were more DEGs in QY1 than in QY3, but there were more up-regulated genes in QY3 than in QY1. Based on an additional analysis of the metabolic pathways under drought stress using MapMan, the most different types of metabolism included secondary metabolism, light reaction metabolism and cell wall. The up-regulated genes in QY3 were significantly more prevalent than those in QY1 and were primarily concentrated in flavor IDS, phenylpropanoids, and the shikimate and terpenoids pathway. As a whole, QY1 and QY3 both had a large number of up-regulated genes in the flavor pathway. In addition, the gene analysis of the ABA key metabolic pathway showed that QY3 had more genes in NAC and WRKY than QY1. A weighted gene co-expression network was constructed and divided into modules. By specifically analyzing the expressed modules, four modules were found to have the highest correlation with drought. Further research on the genes revealed that all 16 genes related to histone, ABA and protein kinase were the most significant in these pathways.Conclusions: In summary, these findings represent the first RNA-Seq analysis of drought stress in Jerusalem artichoke, which is of substantial significance to explore the function of drought resistance in Jerusalem artichoke and the unearthing of related genes.

“…The samples were then heated at 120 • C for 30 min and dried at 80 • C overnight to a constant weight. Determination of Na + content was done according to a previous method with minor modification [41]. In brief, the plant samples were ground into powder and passed through a 0.5 mm sieve.…”

The P-type plasma membrane (PM) H+-ATPase plays a major role during the growth and development of a plant. It is also involved in plant resistance to a variety of biotic and abiotic factors, including salt stress. The PM H+-ATPase gene family has been well characterized in Arabidopsis and other crop plants such as rice, cucumber, and potato; however, the same cannot be said in sunflower (Helianthus annuus). In this study, a total of thirteen PM H+-ATPase genes were screened from the recently released sunflower genome database with a comprehensive genome-wide analysis. According to a systematic phylogenetic classification with a previously reported species, the sunflower PM H+-ATPase genes (HHAs) were divided into four sub-clusters (I, II, IV, and V). In addition, systematic bioinformatics analyses such as gene structure analysis, chromosome location analysis, subcellular localization predication, conserved motifs, and Cis-acting elements of promoter identification were also done. Semi-quantitative PCR analysis data of HHAs in different sunflower tissues revealed the specificity of gene spatiotemporal expression and sub-cluster grouping. Those belonging to sub-cluster I and II exhibited wide expression in almost all of the tissues studied while sub-cluster IV and V seldom showed expression. In addition, the expression of HHA4, HHA11, and HHA13 was shown to be induced by salt stress. The transgenic plants overexpressing HHA4 and HHA11 showed higher salinity tolerance compared with wild-type plants. Further analysis showed that the Na+ content of transgenic Arabidopsis plants decreased under salt stress, which indicates that PM H+ ATPase participates in the physiological process of Na+ efflux, resulting in salt resistance of the plants. This study is the first to identify and analyze the sunflower PM H+ ATPase gene family. It does not only lay foundation for future research but also demonstrates the role played by HHAs in salt stress tolerance.

Soil salinity is a growing challenge for today’s agriculture. It is one of the most brutal abiotic factors limiting crop productivity globally. Millions of hectares of agricultural land throughout the world are too saline to produce economic crop yields and the area affected by salt accumulation is increasing day by day. Saline soils could however be a potential land resource with utilization value under the process of phytoremediation. Wild soybean (Glycine soja) is a salt-tolerant plant widely used in the cosmetic and pharmaceuticals industries as well as in crop improvement programs. This crop shows potential value for saline soil phytoremediation. However, due to its procumbent growth habit, accumulation of biomass is reduced and consequently reducing its value in phytoremediation. In this study, artificial facilities were used to make wild soybeans grow upright. Compared to the control plants, which yielded 1629.74 kg/ha of seed and 6075.76 kg/ha above ground biomass, erect wild soybean plants yielded 2608.10 kg/ha of seed and 10,286.40 kg/ha of above ground biomass (dry weight). The potential phytoremediation ability of wild soybean was also studied. The wild soybean could absorb up to 264.57 kg soluble salt/ha/year with an average of 25.72‰ salt content. The soluble salt content in the wild soybean rhizosphere was 1.50‰ higher than that in the bulk soil, suggesting that the rhizosphere of wild soybean can enrich soluble salt. The K–Na ratio of seed, leaf, shoot, and capsule were all greater than 1 suggesting that the wild soybean has a good salt tolerance capacity. Additionally, the bioaccumulation factor (BF) value of Na in roots was >1 suggesting that the root of wild soybean was the main organ for Na+ storage and suitable for Na phytostabilization. Furthermore, wild soybean could be potentially play an important role in Ca and Mg phytostabilization due to their corresponding BF values, which were greater than 1 in different organs. In other words, the establishment of a cultivation mode of wild soybean, as demonstrated in this study, will be a bridge towards phytoremediation of saline soils and better industrial utilization of the crop.
