Transfer of genes from heterologous species provides the means of selectively introducing
new traits into crop plants and expanding the gene pool beyond what has been available to …

The most widely used technique for the introduction of new genetic information into plant
cells is based on the natural gene transfer capacity of Agrobacterium tumefaciens. Currently …

Various factors affecting mannose selection for the production of transgenic plants were
studied using Agrobacterium tumefaciens-mediated transformation of sugar beet (Beta …

Expiants of five plant species (Allium cepa, Antirrhinum majus, Brassica campestris. Glycine
max, and Nicotiana tabacum) were co-cultivated with three Agrobacterium tumefaciens …

1. It has been suggested that genetic modification could lead to crops with enhanced
invasiveness and persistence. These new genotypes could invade natural ecosystems and …

In Arabidopsis thaliana, six vacuolar Na+/H+ antiporters (AtNHX1‐6) were identified. Among
them, AtNHX1, 2 and 5 are functional Na+/H+ antiporters with the most abundant expression …

A new method for the selection of transgenic rice plants without the use of antibiotics or
herbicides has been developed. The phosphomannose isomerase (PMI) gene from …

Selectable markers enable transgenic plants or cells to be identified after transformation.
They can be divided into positive and negative markers conferring a selective advantage or …

The expression of foreign genes in pollen may pose potential problems in the field release
of transgenic plants, since pollen represents a route whereby foreign genes and their …

With advances in recombinant DNA methods and transformation procedures, it is possible to
transfer genes into crop plants from unrelated plants, microbes and animals. Many of the …
