Comparaison de différentes méthodes d'extraction d'acides dicaféoylquiniques à partir d'une plante halophile

Lorène Gourguillon, Émilie Destandau, Annelise Lobstein, Éric Lesellier

Comptes Rendus Chimie > 2016 > 19 > 9 > 1133-1141

The aim of this study is the evaluation of different extraction methods for dicaffeoylquinic acids (diCQA), previously identified by a LC-DAD-ESI-QTOF dereplication strategy from a halophyte plant rich in polyphenols. Three different eco-friendly extraction methods are tested: microwave-assisted extraction (MAE), pressurized fluid extraction (PFE), supercritical fluid extraction (SFE). Various specific...

Early‐responsive molecular signatures associated with halophytic adaptation in Sesuvium portulacastrum (L.)

Jayant Kulkarni, Sripati A. Sahoo, Pawel Herzyk, Vitthal T. Barvkar, more

Plant, Cell & Environment > 47 > 3 > 961 - 975

Sesuvium portulacastrum (L.) is a halophyte, adapted to grow naturally under saline environments. The ability to use Na and K interchangeably indicated its facultative halophyte nature. No significant growth reduction occurs in seedlings up to 250 mM NaCl, except for curling of the youngest leaf. Within 8 h of salt treatment, seedlings accumulate proline, glycine betaine and other amino acids in both...

Fluorescence parameters of chlorophyll a halophytes as a response to salinity of post mining subsidence reservoirs

Edyta Sierka, Michał Bujok, Barbara Stalmachova, Tomasz Horaczek

Journal of Water and Land Development > 2022 > Special Issue > 164--170

The increasing salinity of water in reservoirs is caused by climate change. On the other hand, an increase in salinity promotes the group species, halophytes that tolerate or need NaCl for growth. The aim of this study was to identify the response of facultative halophytes’ photosynthetic apparatus efficiency (PE) to water salinity. The study covered the spiny water nymph (Najas marina L.) population...

Chen Gu, Jiyan Shi, Yanming Yu, Jianliang Rui, more

CLEAN – Soil, Air, Water > 51 > 9 > n/a - n/a

Vegetation restoration is a vital ecological remediation technology for greening saline‐alkaline soils. However, little attention is paid to the seasonal changes of soil remediation under different vegetation coverage. This study investigated a recently restored coastal tidal flat located on the island of Zhoushan, by examining shifts in physicochemical properties, enzyme activities, and bacterial...

Potential of innovative marine aquaculture techniques to close nutrient cycles

Ricarda Lothmann, Hani Sewilam

Reviews in Aquaculture > 15 > 3 > 947 - 964

Aquaculture is an established technique for producing marine species. However, it creates large amounts of nutrient‐rich waste. Therefore, it is worth examining the methods available to use these nutrients and close the nutrient cycle. This review covers research activities of different saline water methods for food production. These are Integrated Multi‐Trophic Aquaculture (IMTA), Biofloc Technology...

Stalk cell polar ion transport provide for bladder‐based salinity tolerance in Chenopodium quinoa

Nadia Bazihizina, Jennifer Böhm, Maxim Messerer, Christian Stigloher, more

New Phytologist > 235 > 5 > 1822 - 1835

Chenopodium quinoa uses epidermal bladder cells (EBCs) to sequester excess salt. Each EBC complex consists of a leaf epidermal cell, a stalk cell, and the bladder. Under salt stress, sodium (Na⁺), chloride (Cl⁻), potassium (K⁺) and various metabolites are shuttled from the leaf lamina to the bladders. Stalk cells operate as both a selectivity filter and a flux controller. In line with the nature...

Proteomic analysis revealed modulations of carbon and nitrogen by arbuscular mycorrhizal fungi associated with the halophyte Suaeda salsa in a moderately saline environment

Fengwei Diao, Bingbing Jia, Xiuhong Wang, Junqing Luo, more

Land Degradation & Development > 33 > 11 > 1933 - 1943

Halophytes can grow well in moderately salty habitats that restrain most plant growth. Arbuscular mycorrhizal fungi (AMF) can assist its host plants to effectively mitigate salinity stress. However, less information is available on the molecular mechanisms of AMF related to halophytes in adapting to moderate saline environments. A pot experiment was undertaken to detect the effects of AMF on the carbon...

Hybridization, polyploidy and clonality influence geographic patterns of diversity and salt tolerance in the model halophyte seashore paspalum (Paspalum vaginatum)

David M. Goad, Ivan Baxter, Elizabeth A. Kellogg, Kenneth M. Olsen

Molecular Ecology > 30 > 1 > 148 - 161

In plant species, variation in levels of clonality, ploidy and interspecific hybridization can interact to influence geographic patterns of genetic diversity. These factors commonly vary in plants that specialize on saline habitats (halophytes) and may play a role in how they adapt to salinity variation across their range. One such halophyte is the turfgrass and emerging genomic model system seashore...

NADPH oxidases and the evolution of plant salinity tolerance

Minmin Liu, Huiyang Yu, Bo Ouyang, Chunmei Shi, more

Plant, Cell & Environment > 43 > 12 > 2957 - 2968

Soil salinization is a major threat to global food security and the biodiversity of natural ecosystems. To adapt to salt stress, plants rely on ROS‐mediated signalling networks that operate upstream of a broad array of physiological and genetic processes. A key player in ROS signalling is NADPH oxidase, a plasma‐membrane‐bound enzyme encoded by RBOH genes. In this study, we have conducted a comprehensive...

The energy cost of the tonoplast futile sodium leak

Sergey Shabala, Guang Chen, Zhong‐Hua Chen, Igor Pottosin

New Phytologist > 225 > 3 > 1105 - 1110

Summary Active removal of Na⁺ from the cytosol into the vacuole plays a critical role in salinity tissue tolerance, but another, often neglected component of this trait is Na⁺ retention in vacuoles. This retention is based on an efficient control of Na⁺‐permeable slow‐ and fast‐vacuolar channels that mediate the back‐leak of Na⁺ into cytosol and, if not regulated tightly, could result in a futile...

BMC Plant Biology > 2019 > 19 > 1 > 1-14

Background Salicornia europaea, a succulent obligatory halophyte is the most salt-tolerant plant species in the world. It survives salt concentrations of more than 1 M. Therefore, it is a suitable model plant to identify genes involved in salt tolerance mechanisms that can be used for the improvement of crops. The changes in a plant’s gene expression in response to abiotic stresses may depend on factors...

Acta Physiologiae Plantarum > 2019 > 41 > 8 > 1-10

Kallar grass (Leptochloa fusca) is a perennial C4 halophytic species with high salt tolerant. The present research was made to investigate the physio-biochemical characters and transcriptional changes of L. fusca under varying salinity levels (0–600 mM NaCl). The Na⁺ level in shoots and roots increased significantly, whereas the K⁺ content was maintained high in 300 mM NaCl and then declined with...

Ming-Xi Zhou, Marie-Eve Renard, Muriel Quinet, Stanley Lutts

Plant and Soil > 2019 > 441 > 1-2 > 525-542

Background and aims Proline and glycinebetaine are osmolytes playing a role in resistance to salt and water stress but their involvement in plant adaptation to heavy metals remain unclear. Methods Young plants of the halophyte Kosteletzkya pentacarpos were grown in nutrient solution in the presence of Cd (20 or 40 μM) or Zn (200 or 400 μM), or a combination of both heavy metals and in the presence...
