Abstract
The production of interspecific and intergeneric (wide) hybrids is of considerable scientific interest because it enables interactions between two different genomes to be analyzed. Normally, a pollen tube follows the pathway shown in table 1 after germination of the grain. Analysis of the behavior of “alien” pollen tubes (from a different species) indicates some of the points where there is communication between the female sporophyte and male gametophyte. In mature hybrid plants, we have been able to analyze the positions of parental genomes and gene expression in ways that would be impossible in a species (see Heslop-Harrison, 1990; Heslop-Harrison and Bennett, 1990).
