Plant diversity

  • Diversity of plant form and life history and their distribution onto different habitats suggest that plant functions should underlie this diversity, providing tools to successfully and differentially thrive in every habitat. The knowledge of these functions is then the key to understand community and ecosystem structure and functioning, something that attracted the interest and effort of many plant ecologists trying to establish patterns of adaptive specialization in plants.

  • The wide geographical distribution of the rice plant ( Oryza sativa L.) and its long history of cultivation in Asian countries have led to the development of a great diversity of varietal types. Similarly, workers in various rice-growing countries use different terms to designate identical morphological and physiological characters, agronomic traits, gene symbols, and cultural practices. Whereas varietal diversity in germ plasm is desired in rice breeding, variations in nomenclature hinder scientific communication among the workers.

  • Salinity stress negatively impacts agricultural yield throughout the world affecting production whether it is for subsistence or economic gain. The plant response to salinity consists of numerous processes that must function in coordination to alleviate both cellular hyperosmolarity and ion disequilibrium. In addition, crop plants must be capable of satisfactory biomass production in a saline environment (yield stability).

  • Bacteria that associate with plants are diverse in their ability to affect plant health, their genotypic and phenotypic characteristics, and their phylogeny. These bacteria are typically members of complex microbial communities, with only a few establishing pure clonal populations within a plant.

  • Invasive alien plants are harmful non-native plant species whose introduction or spread threatens the environment, the economy, and society, including human health. They can be introduced into Canada from other countries or continents, or from one region of Canada to another. The current threats posed by invasive alien plants are real and growing. Why are invasive alien plants a problem? The economic cost of invasive alien plants to Canadians is enormous. Weeds in crops and pastures alone cost an estimated $2.2 billion annually.

  • This authoritative new work analyses European plant intellectual property rights. Whilst the focus of the work is on Europe, and in particular the European Patent Convention, the Council Regulation on Community Plant Variety Rights and the EU Directive on the Legal Protection of Biotechnological Inventions, these provisions are discussed within the context of international legislation, including the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs) and the Convention on Biological Diversity.

  • This book is about the conservation of genetic diversity of wild plants in situ in their natural surroundings, primarily in existing protected areas but also outside conventional protected areas. A lot of effort has been dedicated to conserving plant biodiversity, but most of this has focused on rare plant communities or individual species threatened with extinction.

  • Non coding endogenous RNAs were first discovered in the last decade of the previous century. These new discoveries changed our views of the transcriptome landscape of plant genomes and paradigms of the regulation of gene expression. With the beginning of this century, we have witnessed an explosion of studies on small regulatory RNAs that has yielded a basic understanding of the many types of small RNAs in diverse eukaryotic species and how they are functioning as RNA–protein complexes along the RNA silencing pathways.

  • The theoretical metrics developed, such as genetic variance and heritability (Fisher, 1930; Wright, 1931), provided the quantitative standards necessary for the evolutionary synthesis. Further research has focused on the origin of genetic diversity, its maintenance and its role in evolution. Simple questions such as “who breeds with whom” initiated studies on the relatedness of populations.

  • Does this mean that differences in genetic diversity levels will have predictable ecological consequences? The answer is no, because only one portion of genetic diversity is connected to ecological factors, i.e. adaptation. Ecological adaptation is a significant factor for example, in range expansion of plant species. Plants with different genotypes conferring the highest levels of fitness are expected to survive and reproduce better, shifting the gene pool over time towards higher frequencies of the alleles making up the more successful genotypes (Ward et al., 2008).

  • It is difficult to discern exposures from institutions’ reported credit market posi- tions. Indeed, common data sources such as annual reports and regulatory filings record accounting measures on a large and diverse number of credit market instruments. Ac- counting measures are not necessarily comparable across positions. For example, the economic value of two loans with the same book value but different maturities will react quite differently to changes in interest rates. At the same time, many instruments are close substitutes and thus entail essentially the same market risk.
