Abstract
Phosphate is an important macronutrient of higher plants, the molecular transport mechanisms of which have not been investigated until recently. Genetical optimizing of arable crops in their phosphate acquisition efficiency is highly desirable, in order to take advantage of their full genetic yield potential. Phosphate greatly influences the yield of crop plants because its lack has detrimental effects on growth, flowering, fruit setting and ripening. Genetic modification however, requires knowledge of the molecules involved in this process. To this end we isolated three cDNAs from potato that showed homology to a high affinity phosphate transporter from Saccharomyces cerevisiae. This paper summarizes the characterisation of two of these clones so far, using yeast as an heterologous expression system and analysis of the genes at the transcriptional level. The results will be discussed in respect to more recent publications in this field. This summary is part of an oral presentation given at the “Sixth International Symposium on Genetics and Molecular Biology of Plant Nutrition” in Elsinore, Denmark.
