Adoption of recently introduced herbicide tolerant soybean varieties has been extremely rapid. By 1998, approximately 38% of the total US soybean acreage was planted to varieties developed through the use of biotechnology methods to be tolerant to various herbicides. The first herbicide tolerant varieties, sulfonylurea tolerant soybeans, were introduced in 1993 and were developed to tolerate higher rates

Take-all decline (TAD) is a natural biological control of the wheat root disease “take-all” that develops in response to the disease during extended monoculture of wheat. The research to date on TAD has been mostly descriptive and no particular occurrence is yet fully understood.

Iron deficiency is a limiting factor of plant growth. Iron is present at high quantities in soils, but its availability to plants is usually very low, and therefore iron deficiency is a common problem.

In this paper, we report direct measurement of an influx of extracellular Ca²⁺ induced by gamete fusion in flowering plants. This result was obtained during maize in vitro fertilization with the use of an extracellular Ca²⁺

Since 1987, when the International Organisation for Standardisation first published the ISO 9000 series of quality standards, the world-wide take up of quality certification to the ISO 9000 standard (QCert) has been increasing rapidly. At the end of 1998, more than 270,000 firms in over 143 countries, will be certified to the standard, an increase of 48,000 on the previous year (ISO, 1999). The
