Lobularia maritima or sweet alyssum (Brassicaceae) is an annual littoral halophyte, naturally thriving on sandy beaches. In addition to its obvious interest as a salt-tolerant plant, this species mainly cultivated ornamental plant in many countries. Laboratory experiments were carried out assess the effects of salinity seed germination and recovery from saline conditions after transfer distille...

UNLABELLED • PREMISE OF THE STUDY Microsatellite primers were developed in the beach plum, Prunus maritima, to investigate the genetic composition of remaining populations in need of conservation and, in future studies, to determine its relation to P. maritima var. gravesii. • METHODS AND RESULTS Fourteen primer pairs were identified and tested in four populations throughout the species' ge...

We report on the Tydeidae and Triophtydeidae associated with grapevine (Vitis labrusca L. and Vitis vinifera L.) in Rio Grande do Sul State, Brazil, and describe a new species of Prelorryia, Prelorryia labrusca sp. nov., and two new species of Tydeus, Tydeus manoi sp. nov. and Tydeus riopardensis sp. nov. Brachytydeus formosa (Cooreman), B. podocarpa (Baker), Neolorryia pandana (Baker), Tydeus ...

III Riassunto V Papers published or prepared in the course of the PhD VII Preface IX General introduction 1 Chapter 1 Seed germination responses to varying environmental conditions and provenances in Crucianella maritima L., a threatened coastal species 9 Chapter 2 The effect of seagrass beach-cast on germination and growth of dune plants 16 Chapter 3 High levels of stranded wrack from seagrass...

Artemisia species possess pharmacological properties that are used for medical purposes worldwide. In this paper, the essential oils from the aerial parts of Artemisia nilagirica and Artemisia maritima from the western Indian Himalaya region are described. The main compounds analyzed by simultaneous GC/MS and GC/FID were camphor and 1,8-cineole from A. maritima, and camphor and artemisia ketone...

The reduction of crop yield caused by soil salinization has become a global problem. Halophytes improve saline alkali soil, and the halophyte transcription factors that regulate salt stress are crucial for improving tolerance. In this study, 1466 were identified transcriptome sequencing analysis Glaux maritima leaves after (0, 600, 800 mM/L NaCl). Their genes distributed across 57 factor famili...

Glucosinolates from seed meals of Erysimum hieracifoliwn and l\1alcolmia mantlma were treated with thioglucosidase (EC 3.2.3.1). and the resultant aglucon products investigated. A major product from E. hieracifoliwll was 3-hydroxypropyl isothiocyanate from the novel precursor 3-hydroxypropylglucosinolate. Other aglucon products were 3-methylsulfonylpropyL 3-methylsulfinylpropyl. 3-methylthiopro...

Cultivation of salt-tolerant crops help to face irreversible global salinization freshwater and soils. In New-Caledonia, three halophytes are candidates for saline crops, Salsola australis R.Br., Suaeda maritima (L.) Dumort Enchylaena tomentosa R.Br. Their success quality depend yet on availabilities salinity essential nutrients in agrosystems. So, we investigated effects salinities, i.e., cont...

Batch cultures of Thermotoga maritima were performed in a bioreactor equipped with instruments adapted for experiments performed at 80°C to mimic the fluctuating oxidative conditions in the hot ecosystems it inhabits. When grown anaerobically on glucose, T. maritima was shown to significantly decrease the redox potential (Eh) of the culture medium down to about -480 mV, as long as glucose was a...
