Abstract

We tried to isolating a noble gene from cucumber library with heterogeneouse RNA probe labeled DIG of Arabidopsis PIN3 gene. Two kinds of RNA probes which had no significant homology each others, were designed from the 5'- and 3'- prime nucleotides of the AtPIN3 gene. In the first and second screenings of the cDNA library of cucumber with the probes, two positive clones were identified with specific duplicate signals. However, we isolated cDNA fragments homologous with putative nucleases from Nicotiana, Arabidopsis, Cordialis, and Oryza sativa, there was no significant homology with any other PIN family genes.
