| Outline of Final Research Achievements |
Researches about pollen tube guidance have not well investigated in rice, and pollen tube attractants are not identified in rice until now. To search pollen tube attractants in rice, I searched rice pollen tube attractants based on detailed gene expression profiles of the rice synergid cell. As a result of careful examination of gene expression profiles, interestingly, LURE genes which had been identified as pollen tube attractants in Torenia and Arabidopsis did not exist in the highly expressed genes of rice synergid cell. On the other hand, a lot of genes encoding unknown secreted proteins were highly expressed in the rice synergid cell, so they seemed to be promising candidates for the pollen tube attractants in rice.
