| Outline of Final Research Achievements |
Microhairs, which are considered to increase salt tolerance, and macrohairs, which are considered to increase insect resistance, are distributed on the leaf surface of salt-tolerant plants belonging to the subfamily Chloridoideae in the Poaceae. The numbers of microhairs and macrohairs are considered to increase or decrease by salt-stress or feeding damage. We have showed by scanning electron microscopy that both of the microhairs and macrohairs developed from undifferentiated cells in the same position of the leaves. We have also clarified that the salt-treatment increased the number of microhairs but did not affect that of macrohairs. The treatment of jasmonic acid, abscisic acid, and cytokinin did not cause such as phenomenon.
