Several countries of Asia, including Malaysia, have in recent years experienced spectacular economic growth and social change. This, together with declining fertility rates and mortality rates, and accompanying increased expectation of life at birth have resulted in rapid population ageing of these countries. However, relative to the developed countries, where fertility and mortality declines, ...

1% in 2000. Although the objective was far from being reached (the current rate being close to 2%), in 2000 Mexico had 53 million inhabitants fewer than it would have had if fertility had remained at its 1970 level. The population pyramids of 1930, 1970 and 2000 clearly illustrate this dynamics (Figure 2). In 1930 the population was beginning to recover from the aftereffects of the Revolution a...

Plant stilbenes are phytoalexins that accumulate in a small number of plant species, including grapevine (Vitis vinifera), in response to biotic and abiotic stresses and have been implicated in many beneficial effects on human health. In particular, resveratrol, the basic unit of all other complex stilbenes, has received widespread attention because of its cardio-protective, anticarcinogenic, a...

Grapevine stilbenes, particularly trans-resveratrol, have a demonstrated pharmacological activity. Other natural stilbenes derived from resveratrol such as pterostilbene or piceatannol, display higher oral bioavailability and bioactivity than the parent compound, but are far less abundant in natural sources. Thus, to efficiently obtain these bioactive resveratrol derivatives, there is a need to...

Resveratrol contributes to a plant's tolerance of various abiotic and biotic stresses and is highly beneficial to human health. A search for elite alleles affecting resveratrol production was undertaken to find useful grapevine germplasm resources. Resveratrol levels in both berry skins and leaves were determined in 95 grapevine accessions (including 50 wild Chinese grapevine accessions and 45 ...

Inoculation of the grapevine (Vitis amurensis Rupr.) with the arbuscular mycorrhizal (AM) fungus Glomus versiforme significantly increased resistance against the root-knot nematode (RKN) Meloidogyne incognita. Studies using relative quantitative reverse transcription-PCR (RQRT-PCR) analysis of grapevine root inoculation with the AM fungus revealed an up-regulation of VCH3 transcripts. This incr...

The distribution of carbon (C) into whole grapevine fruiting cuttings was investigated during flower development to determine the relative contribution of inflorescence and leaf photoassimilates in the total C balance and to investigate their partitioning towards other plant organs. A (13)C labelling procedure was used to label C photoassimilates by leaves and inflorescences in grapevine. Inves...

Wild grapevine genetic diversity in southeast Turkey has not been documented to date. In the present work, in order to clarify the relationships between wild and cultivated grape accessions from southeastern Turkey, 22 nuclear and three chloroplast microsatellite loci were used on 21 wild grapevine Vitis vinifera L. ssp. sylvestris (Gmelin) and 13 cultivated grapevine Vitis vinifera ssp. sativa...
