Existing life-history concepts deal inadequately with clonal organisms. To make them more generally applicable, several assumptions must be widened: (i) life histories may expressed at different levels of individual organization. e. g. genets and modules; (ii) parts a cycle executed than once by single genetic individual; (iii) individuals do not necessarily senesce; (iv) size reproductive value increase indefinitely age; (v) dormancy, dispersal progeny, production genetically progeny are...
As the human population grows from 7.8 billion to 10 over next 30 years, breeders must do everything possible create crops that are highly productive and nutritious, while simultaneously having less of an environmental footprint. Rice will play a critical role in meeting this demand thus, knowledge full repertoire genetic diversity exists germplasm banks across globe is required. To meet demand, we describe generation, validation preliminary analyses transposable element long-range...
The -3/2 power rule, or self-thinning was accepted 10 years ago as an important generalization, but has recently been questioned by a number of authors. This paper assesses what remains the rule. While it empirically established that size-density trajectories followed plant populations do not necessarily follow slope, more general rule describing density-dependent upper limit to mean shoot biomass per (the '-3/2 boundary rule') largely intact. Principal component analysis (PCA) overestimates...
Summary Aromatic rice is highly prized by most consumers, and many countries cultivate traditional improved aromatic varieties. 2‐Acetyl‐1‐pyrroline (2AP) the major compound in rice, believed to accumulate because of an eight‐base‐pair (8‐bp) deletion allele at fragrance locus. In this study, 2AP was quantified presence or absence ( fgr ) determined 464 samples varieties from T.T. Chang Genetic Resources Centre International Rice Research Institute. It shown that a number varieties,...
Understanding variation in seed longevity, especially within closely related germplasm, will lead to better understanding of the molecular basis this trait, which is particularly important for genebanks, but also relevant anyone handling seeds. We therefore set out determine relative longevity diverse Indica rice accessions through storage experiments. Since antioxidants are purported play a role storability, antioxidant activity and phenolic content caryopses were determined.Seeds 299...

1 Wilkinson (2001) argues that we cannot assume hybrids between local and alien genotypes will have low fitness, therefore, as hybrid fitness has been presented justification for using only locally provenanced material in habitat restoration schemes, provenance is not important. 2 His observations on are important, correct deserve wider recognition. 3 Nevertheless, I dispute his conclusion about the importance of provenance, two main reasons. One argument based questionable objectives...
Summary Grants for wildlife enhancement in the British Isles have supported widespread planting of new hedges along field margins. However, much planted material, particularly hawthorn Crataegus monogyna , has been obtained from continental mainland Europe. There is a need to assess implications this practice hedgerow performance and conservation indigenous genetic variation. One local ecotype eight commercial provenances (four four European) were an experimental hedge at both exposed upland...
Improved winter hardiness is an important breeding objective in the forage grass Lolium perenne. This a complex trait with several components, including ability to survive and grow at low temperature, acclimate cold, tolerate wind, snow cover ice encasement. Marker-assisted selection has potential increase efficiency of for improved cold tolerance. Here we describe genecological approach identifying molecular markers that are associated adaptation temperatures. AFLP was used assess genetic...
Genebanks underpin global food security, conserving and distributing agrobiodiversity for use in research breeding. The CGIAR collections include >700,000 seed accessions, held trust as public goods. However, the role of genebanks contributing to security can only be realized if are effectively managed. Examination historical viability monitoring data from seven confirmed that high was maintained many decades various crops forage species. departures optimum management procedures were...
Abstract Wild relatives of rice in the genus Oryza (composed 24 species with 11 different genome types) have been significantly contributing to varietal improvement ( sativa ). More than 4000 accessions wild are available and they regarded as a “genetic reservoir” for further improvement. DNA markers essential tools genetic analysis breeding. To date, genome-wide marker sets not well established this is one major difficulties efficient use germplasm. Here, we developed 541 InDel...
Plant genetic resources (PGR), including collections held in national and international gene banks, provide access to a wide array of diversity are critical genomics research, conservation efforts, applied breeding. Yet, there is general lack awareness the research community about rules treaties that govern use PGR, benefit sharing obligations contained and/or laws, how best comply with potentially applicable requirements. This article provides brief history overview three key agreements,...
We evaluated the use of amplified fragment length polymorphism (AFLP) markers to distinguish genotypes, populations and species Lolium. Accessions two Lolium perenne multiflorum their hybrid x hybridum, collected by Institute Grass Environmental Research in 1995 from locations across Portugal, were used. The genetic variation within between extremes latitude altitude was determined assessed. Three primer pair combinations generated 765 polymorphic bands. Principal coordinate analysis...
Abstract Seeds of 15 diverse rice accessions, representing aus , indica temperate japonica and tropical subpopulations, were produced under climate conditions in Korea used for vitamin E analysis seed storage experiments at 45°C 10.9% moisture content. High γ -tocotrienol was significantly positively correlated with longevity. In addition, a high β -tocopherol proportion relative to δ negatively Using high-density single-nucleotide polymorphism marker data, DNA haplotype showed clear allelic...
Abstract Molecular genecology is the study of geographical clines in frequencies molecular markers and their relationship to ecological environmental conditions. This outlines principles underlying selection populations, focusing on avoiding ‘false positives’— noncausal correlations between allele frequency environment. The are illustrated by identifying a set populations Lolium perenne for temperature responses. selected encompasses 20 °C range mean January temperature. Their freezing...
