Abstract:

Phylogenetic studies are providing powerful new insights into the evolution of complex traits. Metal hyperaccumulation is an unusual and complex physiological trait found in about 500 plant species and is associated with an exceptionally high degree of tolerance of metalliferous soils. Alyssum L. (Brassicaceae) is the largest known hyperaccumulator genus, comprising approximately 188 species distributed throughout the Mediterranean region and south-west Asia. Approximately one-quarter of these are largely restricted to areas of serpentine soils and have the ability to accumulate nickel to high

Abstract:

Les plantes hyperaccumulatrices pourraient constituer une alternative ou un complément aux méthodes physico-chimiques pour le traitement des sols pollués par les métaux. L’efficacité de cette phytoextraction repose en grande partie sur la biodisponibilité des métaux présents dans les sols. La thèse était destinée à comprendre les processus de fourniture des métaux du sol aux hyperaccumulateurs. Dans ce but, une prospection de terrain a d'abord été effectuée en Albanie pour déterminer la flore métallicole présente sur des sites de serpentines présentant des teneurs élevées en Cd, Co, Cr et Ni e

Abstract:

Hoary alyssum (Berteroa incana (L.) DC) has become a serious weed of rangelands, pastures, and forage crops in British Columbia. In order to develop effective management strategies for this weed, a sound knowledge of its biology and ecology is essential. The goal of this research is to improve our understanding of the biology of hoary alyssum and to identify vulnerable links in its persistence strategy that may be exploited to develop effective management strategies for this weed. The distribution of hoary alyssum seeds in the soil profile; the size and persistence of its seed bank; the effec

L’application de l’agromine à des zones ultramafiques délaissées constitue un enjeu majeur à la vue des surfaces potentiellement valorisables. Par contre, les sols ultramafiques sont particuliers avec de fortes concentrations en métaux et une quasi absence de matière organique. Malgré tout, la mise en place de l’agromine a déjà donné de bons résultats, couplée avec l’application d’herbicides et une fertilisation minérale. Notre défi a été de développer une agromine durable par la mise en place d’agro-écosystèmes basés sur l’introduction d’une légumineuse en association avec une plante hyperacc

Certaines plantes, dites hyperaccumulatrices, ont la capacité de se développer sur des sols riches en métaux et d’accumuler ces métaux à des concentrations élevées.

Ce travail s’inscrit dans la continuité d’une recherche menée par l’équipe depuis plusieurs années, qui a donné lieu notamment à un brevet sur la production du sel double sulfate de nickel et d’ammonium hexahydraté (ANSH) à partir de la biomasse d’Alyssum murale.

Abstract:

Due to the high nickel concentrations, serpentine soils provide a very restrictive and selective environment for plant life. Some plants, termed “Ni-hyperaccumulators”, are adapted to live on these heavy-metal-enriched soils without toxicity symptoms. Ni-hyperaccumulators are increasingly important for research on metal tolerance, homeostasis and biotechnological applications. This project aims to investigate nickel accumulation in taxa and populations of Odontarrhena, a genus of tribe Alysseae (Brassicaceae) that includes over 85 species many of which are Ni-hyperaccumulators.

Reliable, high-throughput and low-cost next-generation sequencing technologies have invigorated genetic research into non-model organisms over the last decade. In this work, RNA-Seq was employed to obtain the first-ever transcriptomes of two groups of closely related plant taxa possessing distinctive complex physiological traits, namely metal hyperaccumulation and C4 photosynthesis. Metal hyperaccumulator plants possess an extraordinary ability to take up trace elements from the soil and accumulate them to high concentrations in their shoots, probably to serve as a type of elemental defence ag

Abstract:

Understanding the challenges parents of children with disabilities face when seeking to balance work and family is a real concern; however, these challenges have not been well studied. Parents of children with disabilities experience excess challenges in the home domain as a result of their caregiving demands that can lead to challenges in balancing family and work. This is particularly problematic for parents raising children with autism spectrum disorder (ASD). The present study examined the relationship between inter-domain transitions and work-family conflict in order to identify personal

Abstract:

In this study, buckwheat (Fagopyrum esculentum Moench) and alyssum (Lobularia maritima (L.)) flowers were used to examine the effect of floral resources on the efficacy of the leafroller parasitoid Dolichogenidea tasmanica (Cameron) in vineyards. This was done by assessing the influence of these flowers on parasitoid abundance and parasitism rate, and by investigating the consequences of this for leafroller abundance. In laboratory experiments, alyssum flowers were used to investigate the effect of floral food on the longevity, fecundity and sex ratio of D. tasmanica. Dolichogenidea tasmanica
