“…However, the accumulation of underground dry matter and e ciency of transport of non-reducing sugar to tubers continued to decrease, and the synthesis of IAA and GA3 in the leaves and tubers was inhibited, while the synthesis of ABA signi cantly improved [25]. 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].…”

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.

“…It has been observed that regulation of endogenous hormones in plants is determined not only by a single hormone but also is often the result of co-regulation of two or more hormones through antagonism or combined action [43]. For example, dry matter content and sugar accumulation are positively correlated with GA 3 /ABA and IAA/ABA content ratios in Helianthus tuberosus, and the dynamic balance of endogenous hormones plays an important role in tuber development [44]. In this study, endogenous ABA content was higher in mother individuals than in rejuvenated individuals, whereas ZT content was lower in mother individuals than in rejuvenated individuals.…”

Background Rejuvenation is a key process that enables perennial woody plants to regain growth potential. In Robinia pseudoacacia plantations, natural root sprouting individuals provide good material for studying the rejuvenation of woody plants. However, the physiological differences and molecular mechanisms underlying black locust rejuvenation remain unclear. In this study, we compared the physiological conditions and molecular responses of rejuvenated individuals and mother trees. Results Our analysis of leaf structures and physiological indices showed that the epidermis thickness, leaf thickness and leaf-tissue tightness of rejuvenated individuals were less than those of mother trees. The soluble-sugar content and total SOD activity of rejuvenated individuals were also lower than those of mother trees. The younger the rejuvenated individuals were, the lower the ABA content, ABA/ZT and GA3/ZT in the leaves. The ZT content increased with decreasing age of rejuvenated individuals. Using high-throughput sequencing strategies, the mRNA and miRNA involved in the rejuvenation of black locust were identified. RNA-seq identified 175,862 unigenes by de novo transcript assembly. Of those, 4,727 differentially expressed genes were identified based on clean reads mapped to the assembled transcriptome for gene expression analysis(fold change≥2 or ≤0.5 and q-value≤0.05). These genes were enriched to 53 gene ontology(GO) terms and 20 KEGG pathways (FDR≤0.01). Among these were a major pathway related to flavone and flavonol biosynthesis. High-throughput miRNA sequencing identified a total of 991 miRNAs, including 671 novel miRNAs. Furthermore, 262 known and 625 novel differentially expressed miRNAs were identified(fold change≥1.5 or ≤0.67 and p≤0.05). The main functions identified in the GO analysis of the target predictions overlapped with differentially expressed genes derived from RNA-seq. KEGG pathway enrichment showed that circadian rhythm-fly and signaling pathways regulating pluripotency of stem cells attracted considerable attention during rejuvenation. Conclusion Our study revealed physiological differences between rejuvenated individuals and mother trees of R. pseudoacacia. Differential genes between mother trees and rejuvenated individuals may vary according to the tree ages, but miRNAs may play a key regulatory role in rejuvenation. The same genotype system composed of root germinating individuals and mother-tree individuals provides a solid starting point for further elucidation of the rejuvenation of woody plants.

“…Plants provide oxygen, food, feed, fibers, and building materials, and are a diverse source of industrial and pharmaceutical chemicals (Li et al, 2016a(Li et al, , 2016bTang et al, 2015aTang et al, , 2015bShao et al, 2016). In addition, they are centrally important to the health of ecosystems, and the management and maintenance of a sustainable biosphere necessitates their thorough understanding (Liu et al, 2015;Long et al, 2014Long et al, , 2016aLong et al, , 2016bChenchouni, 2016).…”

The total environment includes 5 closely-linking circles, in which biosphere and lithosphere are the active core. As global population increases and urbanization process accelerates, arable land is gradually decreasing under global climate change and the pressure of various types of environmental pollution. This case is especially for China. Land is the most important resources for human beings' survival. How to increase and manage arable land is the key for sustainable agriculture development. China has extensive marshy land that can be reclamated for the better potential land resources under the pre-condition of protecting the environment, which will be a good way for enlarging globally and managing arable land. Related studies have been conducted in China for the past 30 years and now many results with obvious practical efficiency have been obtained. For summarizing these results, salt-soil will be the main target and related contents such as nutrient transport, use types, biodiversity and interactions with plants from molecular biology to ecology will be covered, in which the interactions among biosphere, lithosphere, atmosphere and anthroposphere will be focused on.
