ecological engineering through the biosecure introduction of kosteletzkya virginica Seashore mallow to saline lands in china a review of 20 years of activity
Ecological Engineering, 2015Co-Authors: Pei Qin, Denise M Seliskar, Ruiming Han, Mingxi Zhou, Huanshi Zhang, Lishan Fan, John L GallagherAbstract:Abstract Over the past 20 years since its introduction, Kosteletzkya virginica has proved to be one of the optimal halophytes for saline land restoration in China. In six Seashore mallow plantations, its well-developed perennial root system promoted the growth of arbuscular mycorrhizal fungus in the rhizosphere, where the fungus’s activity produced total glomalin (TG, ranging from 0.85 to 2.43 mg g −1 soil), with a high ratio of TG/SOC (soil organic carbon) up to 53.29% in six-year-old Seashore mallow plantation. K. virginica ameliorated the condition of saline soils, promoted native species growth, and increased plant diversity in the plantation sites. Seashore mallow contains many bioactive compounds, e.g., polysaccharides, saponins, flavonoids, etc. which have high bioactivity, and could be used as a fodder additive or for the development of health foods. The leaf, flower, stem and root of K. virginica , serve as raw materials for hierachical development of useful products according to their different properties. This study reviews and summarizes research on K. virginica in China during the past 20 years since its introduction from the USA. Also, we present guidelines for the planting and use of Seashore mallow in China, in terms of an ecological engineering roadmap, which illustrates the process and strategy for the restoration of saline soils and designs for biomass industries based on its production.

Seashore mallow kosteletzkya pentacarpos as a salt tolerant feedstock for production of biodiesel and ethanol
ARS USDA Submissions, 2013Co-Authors: Bryan R Moser, Bruce S Dien, Denise M Seliskar, John L GallagherAbstract:Seashore mallow (Kosteletzkya pentacarpos) is a non-invasive perennial nonclonal halophytic oilseed-producing dicot that was investigated as a feedstock for production of biodiesel from seeds and ethanol from residual stem biomass. Seashore mallow seeds contained 19.3 mass % oil, which after extraction with hexane and pretreatment with catalytic sulfuric acid was converted into methyl esters in 94 mass % yield utilizing homogenous base catalysis. The principal components identified were methyl linoleate (48.9%), palmitate (24.4%) and oleate (18.3%). Fuel properties were characterized and compared to biodiesel standards ASTM D6751 and EN 14214. Also investigated were blends with petrodiesel. Lastly, Seashore mallow stems were rich in neutral carbohydrates (51.8 mass %). After simultaneous saccharification and fermentation employing a native Saccharomyces cerevisiae yeast strain, the stems provided ethanol and xylose yields of 104 g/kg and 47.8 g/kg, respectively. Of the four pretreatment methodologies explored, dilute ammonium hydroxide provided the highest yield of sugars.

fertiliser application positively affects plants performance but reduces seed viability in Seashore mallow kosteletzkya pentacarpos implication for biomass production and species conservation
Annals of Applied Biology, 2017Co-Authors: Thomas Abeli, Lisa Brancaleoni, Roberta Marchesini, Simone Orsenigo, Graziano Rossi, Renato GerdolAbstract:Kosteletzkya pentacarpos Seashore mallow, is recognised as an important plant species for several industrial applications, especially in North America and Asia. In Europe, Seashore mallow is highly threatened and subject of conservation actions (e.g. reintroduction). In order to define appropriate multipurpose cultivation protocols, suitable for biomass production and for conservation purposes, we investigated the effect of varying levels of soil salt content and nutrient availability on Seashore mallow. As expected, Seashore mallow had the best performance in terms of growth rate, flowering and fruit production when fertiliser was applied, while salt had only limited effects. Interestingly, seeds produced by fertilised plants showed a lower germination performance and higher mortality than seeds developed from non-fertilised plants. Our results highlight a trade-off between parental plant growth and seed performance, the former being enhanced and the latter being reduced by fertiliser application. The causes of this trade-off are related to a transgenerational maternal effect of fertiliser application that has important implications for Seashore mallow cultivation. Biomass production benefits from fertiliser application but if the quality of seeds and the fitness of the next generation are major objectives (e.g. seed production and species conservation), fertiliser application is not recommended.

Identification and Validation of Reference Genes for Seashore Paspalum Response to Abiotic Stresses
International journal of molecular sciences, 2017Co-Authors: Yu Liu, Jun Liu, Hui Lai, Yu Chen, Zhi Min Yang, Bingru HuangAbstract:Seashore paspalum (Paspalum vaginatum) is among the most salt- and cadmium-tolerant warm-season perennial grass species widely used as turf or forage. The objective of this study was to select stable reference genes for quantitative real-time polymerase chain reaction (qRT-PCR) analysis of Seashore paspalum in response to four abiotic stresses. The stability of 12 potential reference genes was evaluated by four programs (geNorm, NormFinder, BestKeeper, and RefFinder). U2AF combined with glyceraldehyde-3-phosphate dehydrogenase (GAPDH) showed stable expression in Cd-treated leaves and cold-treated roots. U2AF and FBOX were the most stable reference genes in Cd-treated roots and cold-treated leaves. In Polyethylene Glycol (PEG)- or salt-treated roots, the reference gene U2AF paired with either ACT or CYP were stable. SAND and CACS exhibited the most stability in salt-treated leaves, and combining UPL, PP2A, and EF1a was most suitable for PEG-treated leaves. The stability of U2AF and instability of UPL and TUB was validated by analyzing the expression levels of four target genes (MT2a, VP1, PIP1, and Cor413), and were shown to be capable of detecting subtle changes in expression levels of the target genes in Seashore paspalum. This study demonstrated that FBOX, U2AF, and PP2A could be used in future molecular studies that aim to understand the mechanisms of abiotic stress tolerance in Seashore paspalum.
