genetic variation,   etc   ; domestication; evolution; metabolism; metabolites; phenotype;     Show all 6 Subjects
Abstract:
... Plants produce a huge array of metabolites, far more than those produced by most other organisms. Unraveling this diversity and its underlying genetic variation has attracted increasing research attention. Post-genomic profiling platforms have enabled the marriage and mining of the enormous amount of phenotypic and genetic diversity. We review here achievements to date and challenges remaining tha ...

genetic variation,   etc   ; biosynthesis; gene expression; metabolic engineering; phenotype;     Show all 5 Subjects
Abstract:
... Individual cells within a population can display diverse phenotypes due to differences in their local environment, genetic variation, and stochastic expression of genes. Understanding this cell-to-cell variation is important for metabolic engineering applications because variability can impact production. For instance, recent studies have shown that production can be highly heterogeneous among eng ...

Abstract:
... A growing body of empirical work supports and informs the role of genetic variation and contemporary evolution in shaping ecological dynamics at the population, community and ecosystem levels. Although much progress has been made, I contend that reliance on several common empirical and inferential approaches is limiting forward progress in key areas, which leads me to several suggestions. More stu ...

Abstract:
... In higher plants, leaf waxes provide a barrier to non-stomatal water loss, and their composition varies both between and within species. Characteristics of n-alkanes, a suite of ubiquitous compounds in these waxes, are thought to be influenced by the availability of water and the temperature in a plant’s growing environment. Longer n-alkane distributions with less variability in chain length are h ...

Abstract:
... Floral longevity is a critical component of floral display, yet there is a conspicuous paucity of empirical research on its evolution within species. Evolutionary models of floral longevity are grounded in resource allocation theory and propose that selection acts on heritable variation to optimize longevity in light of competing floral construction and maintenance costs. Key assumptions remain un ...

... Carrot (Daucus carota L.) is a member of the Apiaceae family that includes economically important medicinal, ornamentals, seed spices and vegetables. However, the genomic resources in these crops are limited compared to carrot, which is enriched with a number of molecular markers that are publicly available. Hence, we studied the usefulness of the 30 carrot molecular markers for eight different ge ...

Biochemical logic behind the production of La aglycon and glycoside halves and effects of La on ...

Abstract:
... The genomic shock hypothesis suggests that allopolyploidy is associated with genome changes driven by transposable elements, as a response to imbalances between parental insertion loads. To explore this hypothesis, we compared three allotetraploids, Nicotiana arentsii, N. rustica and N. tabacum, which arose over comparable time frames from hybridisation between increasingly divergent diploid speci ...

Abstract:
... Variation in water temperature can have important effects on the energetics underlying metabolism, growth, and reproduction of many organisms. In order to anticipate how a species' allocation of energy may change in a warming ocean, we need to know the degree to which processes such as metabolic rate change with temperature (i.e., the thermal sensitivity of metabolism, Q10). In the context of long ...

Abstract:
... Living organisms are constantly exposed to wide ranges of environmental cues. They react to these cues by undergoing a battery of phenotypic responses, such as by altering their physiological and behavioral traits, in order to adapt and survive in the changed environments. The adaptive response of a species induced by environmental cues is typically thought to be associated with its genetic divers ...
