Promiscuous germination and growth of wildtype pollen from Arabidopsis and related species on the shoot of the Arabidopsis mutant, fiddlehead.

Abstract excerpt

When pollen lands upon the stigmatic surface of a receptive flower, recognition events take place that permit germination, pollen tube growth, and tube penetration into the cell walls of the stigmatic papillae. Previously, we have described a mutant of Arabidopsis thaliana, named fiddlehead (fdh), where noncarpel organs of the shoot fuse late in ontogeny (Lolle et al., 1992). Here we demonstrate that wildtype...
