Abstract

Three treatments consisting of 0%, 15%, and 30% seawater were investigated to analyse the ecotypic variabilities among five populations of Jerusalem artichoke (Helianthus tuberosus) regarding their responses to seawater stress under a hydroponic culture system. Analyses were done 2, 4, and 6 days after treatments. The 15% and 30% seawater treatments reduced the growth rates of roots and shoots of H. tuberosus populations. The activities of superoxide dismutase, peroxidase, and catalase majored in the leaves were stimulated under the seawater stress. The electrolyte leakage and malondialdehyde contents of the leaves were also stimulated owing to seawater stress. The contents of proline and soluble-sugars in the leaves increased significantly with increasing seawater concentrations. The concentrations of Na⁺, K⁺, and Cl⁻in the aerial parts and roots increased with an increase in the seawater concentration throughout the experimental period. There were ecotypic differences among the five populations of H. tuberosus as evidenced by the analyses of the above items in both aerial parts and roots under seawater treatment. The magnitude of the ecotypic variance components indicated that a substantial proportion of the total variation for these physiological and biochemical responses were owing to ecotype, indicating the possibility of improvement through hybridization and selection.

Salt stress affects the biomass of industrial crop Jerusalem artichoke by affecting sugar transport and metabolism
2023, Heliyon
Even though Jerusalem artichoke (Helianthus tuberosus L.) has strong resistance to abiotic stresses, salinity can still reduce the biomass of Jerusalem artichoke. The purpose of this study was to elucidate the differences in the development of Jerusalem artichoke and the dynamics of sugar throughout the growth period under high (7.23–8.15 g/kg) and low (3.20–4.32 g/kg) salinity stress in the field in Jiangsu Province, China. This study confirmed that high salinity promoted the conversion of reducing sugars to non-reducing sugars (fructans) in Jerusalem artichoke tubers, but significantly reduced the biomass of Jerusalem artichoke and advanced the peak time of the dry matter accumulation of aerial parts. In addition, in the early and late stages of tuberization, the total sugar content of tubers under low salinity conditions (786 ± 8 mg/g and 491 ± 8 mg/g) was 93.3% and 1.15 times than those under high salinity conditions, respectively. Moreover, the total sugar content in stems was consistently greater under high than low salinity conditions in the same period. The accumulation rate and the amount of dry matter were significantly higher in stems than in other tissues. Therefore, the aerial parts of “Nanyu No. 1” could be harvested before mid-to-early October, and the tubers after mid-November. This study revealed the internal reasons for the decreased yield of Jerusalem artichoke under salt stress, and provided theoretical basis and guidance for the cultivation and utilization of Jerusalem artichoke in saline-alkali soil.

Shao et al. (2016) found that an appropriate amount of external salt application affects the growth of Jerusalem artichoke seedlings, leading to a decrease in the biomass of roots and aboveground parts, and promoting tuber formation in advance. Although salt stress significantly decreases the photosynthetic efficiency in Jerusalem artichoke (Zhao et al., 2010; Chen et al., 2011a,b), the accumulation of osmotic regulators (e.g., betaine, proline, and soluble sugar), selective absorption of Na+/K+, increased activity of antioxidant enzymes and reactive oxygen species (ROS) removal capacity may enhance the capacity to tolerate salinity in the Jerusalem artichoke (Long et al., 2009; Huang et al., 2013; Li et al., 2014; Chen et al., 2014). The expression of HtNHXs was increased by NaCl stress, and overexpression of HtNHX1 or HtNHX2 increased the salt tolerance of transgenic Arabidopsis thaliana and rice plants, suggesting that these genes may be involved in Jerusalem artichoke salt tolerance (Zeng et al., 2018; Li et al., 2020).
Jerusalem artichoke (Helianthus tuberosus L.) is an herbaceous perennial plant in Compositae with certain salt tolerance, but its salt-responsive mechanisms have not been clearly revealed. Suspension cell cultures act as a model system and can support a consistent and coordinated cellular response to salt stress. In the present study, a combination of physiological characteristics and tandem mass tags (TMT)-based proteomic approaches was conducted to investigate the salt response of suspension cell cultures of Jerusalem artichoke. NaCl stress significantly inhibited the proliferation of Jerusalem artichoke suspension cells and caused a decrease in relative cellular activity. In addition, the content of soluble sugar, proline, H₂O_2, and malondialdehyde was affected by salt stress in suspension cells. From the proteomic analysis, a total of 313 upregulated proteins and 365 downregulated proteins were identified after salt stress. Functional analysis showed that the differentially expressed proteins were involved in a variety of biological processes, including the division of cells, reconstruction of water balance components, scavenging of reactive oxygen species (ROS), biogenesis of ribosomes and proteins, and metabolism of carbohydrates. These findings suggest that salt stress affects protein synthesis and cell division and induces the expression of proteins important for the control of ROS production and metabolic homeostasis in Jerusalem artichoke cell culture.
Inulin from Jerusalem artichoke (Helianthus tuberosus L.): From its biosynthesis to its application as bioactive ingredient
2021, Bioactive Carbohydrates and Dietary Fibre
Jerusalem artichoke (Helianthus tuberosus L.) represents a promising crop emerging in different parts of the world as a natural source of inulin. Different factors such as the kind of cultivar, agroecological conditions, harvest time, and tubers storage, have an impact on the inulin content and the physicochemical and biological characteristics. A wide variety of protocols for the extraction of inulin from Jerusalem artichoke tubers have been described that should be applied and selected considering the desired purity, the equipment available, and the environmental impact. The biosynthesis of the inulin during the plant life cycle, the beneficial health effects of Jerusalem artichoke tubers as well as the application of inulin as a bioactive ingredient in functional foods, are presented in this review. The data analyzed revealed that information is missing about the physicochemical characteristics of the inulin used in the different studies. Finally, the reviewed information contributes to the knowledge of the use of this compound as an ingredient in the food industry considering both its technological and bioactive effects.
Effect of sea water substitution on growth, physiological and biochemical processes of coconut (Cocos nucifera L.) seedlings—A hydroponic study
2021, Scientia Horticulturae
Coconut is grown along the coasts and islands that are vulnerable to climate change-induced sea level rise. Though coconut is considered moderately salt tolerant, our understanding on the growth and physiological response to sea water, either inundation or subsurface water contamination, is very limited. This understanding will enable to effectively manage coconut in coastal systems under future climatic scenarios. In this study, ten month old hydroponically grown coconut seedlings were subjected to 0, 10, 25, 50, 75 and 100 % of sea water substitution (SWS), equivalent to 2.17, 8.32, 16.32, 30.03, 42.14 and 53.69 dS m⁻¹ EC, respectively. Substituting Hoagland solution in hydroponic system by sea water of increasing concentration (>50 % SWS) significantly changed physiological processes; Fv/Fm decreased and r_s increased as early as 7 and 18 days after treatment imposition (DAT), respectively which led to significant decline in leaf area and root length expansion as early as 24 DAT. At 25 % SWS, root system (root length and root biomass) was stable but the aerial part biomass was declined by 47 %. On the other hand plant height, leaf area, collar girth and biomass accumulation of seedlings under 10 % SWS (8.32 EC) was on par with the control plants suggesting coconut seedlings could tolerate 10 % SWS. Though, P_N declined by 19 % and 43 % at 10 % and 25 % SWS, respectively and a similar decline in g_s without a concomitant change in leaf water potential suggested that root-generated signals regulated the stomatal movement in coconut under salinity. Still the biomass accumulation at 10 % SWS was not affected by decline in P_N. Under increasing sea water treatments, most of the Na⁺ absorbed was compartmentalized in root and shoot, while leaf had more accumulation of K⁺, that ensured high K⁺/Na⁺ ratio in the leaves which is an important salinity tolerant mechanism observed in coconut. The leaf Cl⁻ content also had strong negative correlation with [P_N] (r=-0.873) and biomass (r=-0.833), therefore in addition to K⁺ and Na⁺ homeostasis, the level of tolerance to the increased Cl⁻ content in the leaves may also play an important role in salinity tolerance of coconut. This understanding will help in making appropriate strategies for managing coconut grown at coastal systems in the face of sea level rise under climate change.
Improvement of physico-chemical properties and microbiome in different salinity soils by incorporating Jerusalem artichoke residues

Unlike grain crops, Jerusalem artichoke can grow well in barren, poor-quality land (Li et al., 2013). Jerusalem artichoke distributed throughout the world, and has a number of advantageous characteristics over traditional agricultural crops, including resistance to abiotic stresses (such as its tolerant to salinity and drought), high photosynthetic efficiency, little demand for fertilizer, great ecological resiliency, and high commercial value (Long et al., 2009; Zou et al., 2016). Returning straw to the field is also one of the agronomic measures to improve the saline soil, straw incorporation into soil can efficiently increase soil organic matter and mineral nutrient content, improve soil structure and soil fertility, and increase crop yields (Bijay-Singh et al., 2008; Liao et al., 2013), and because of its low operating cost and easy operation, the impact on soil improvement is also excellent.
Soil salinization is becoming increasingly serious, threatening the development of ecological agriculture that aims at high yield, high efficiency and closed-loop cycles. In this study, residues of Jerusalem artichoke were incorporated in three soils differing in salinity, and the physical and chemical properties of soil and soil microbial community were characterized over time. After residue incorporation, the soil pH fluctuated between 6.8 and 8, trending toward neutrality; the soil salinity decreased significantly. The total nitrogen content increased significantly, whereas the soil organic matter content increased initially and then decreased. Soil microbiome abundance and diversity increased, with a significant increase in the population of moderate halophiles and cellulose-decomposing bacteria in soil. Compared with the genera adapted to medium-to-high salt concentration, the abundance and diversity of the low-salt genera were higher. The degradation rate of residues increased with time, with cellulose degradation being strongest, followed by hemicellulose, and finally lignin. In summary, incorporation of Jerusalem artichoke residues can improve soil physical and chemical properties and the microbial community structure, which provides a theoretical basis for improving saline-alkali soils, rational utilization of crop residues and promoting sustainable development of modern agriculture.
Industrial crop Jerusalem artichoke restored coastal saline soil quality by reducing salt and increasing diversity of bacterial community

Artichokes yield 4 to 15 t ha−1 of carbohydrates (Swanton et al., 1992). Distributed worldwide, the Jerusalem artichoke demonstrates wide ecological adaptability, resistance to abiotic stresses, high resilience and photosynthetic efficiency, little demand for fertilizer, great ecological resiliency and high commercial value (Long et al., 2009; Deng et al., 2016). Its broad range of uses and tolerance to saline-alkali soils and strong breeding capacity, among other traits, making it a candidate to improve the saline soil (Long et al., 2014; Yang et al., 2016) to achieve strong economic, social and ecological benefits.
Salinity is one of the main environmental constraints in soil restricting plant growth and agricultural productivity; however, the utilization of salt-affected land brings substantial benefits. This study investigated an in situ remediation method that involved planting Jerusalem artichokes in naturally occurring saline-alkali soils with different salinities (g salt kg⁻¹ soil), specifically, high salinity (H, >4.0), moderate salinity (M, 2.0–4.0) and low salinity (L, 1.0–2.0), in the coastal saline zone of southeast China. We compared these conditions with corresponding soil controls that were not planted. Soil pH and salinity were increased in bulk and unplanted control soils compared to rhizosphere soils. Neutral phosphatase and invertase showed a significant negative correlation with soil salinity, and there was a significant positive correlation between these two enzymes. While catalase activity decreased in the reverse order. The lowest calcite, muscovite and quartz contents as well as the highest chlorite and albite contents were found in the control soils. Planting Jerusalem artichoke also enhanced bacterial microbiota in saline-alkali soils. Bulk soil Operational Taxonomic Units (OTUs) numbers at high (H), moderate (M) and low (L) salinity were 4177, 5325 and 3672, respectively, and they were 1.27, 1.02 and 1.25 times lower than those in rhizosphere soil. This finding demonstrated that the Jerusalem artichoke played a significant role in enhancing soil microbial richness. In conclusion, Jerusalem artichoke could improve the physical and chemical properties of the soil by released root exudates into soil, increased the diversity and richness of soil microbial communities, and so on, so as to achieved the effect of improved the saline-alkali soil in coastal areas of Dafeng, Jiangsu Province, which provided scientific basis for elaborated the salt-tolerant characteristics of Jerusalem artichoke and improved the mechanism of coastal saline soil function.
