Outline of Final Research Achievements |
Plants take up essential nutrients and water through root in soil. On the other hand, they prevent non-essential substance from entering into plants. This is enabled by endodermis carrying Casparian strip and suberin. However, their mechanisms of formation and physiological function remain unclear. In out work, we have identified novel protein involved in Casparian strip formation. In addition, through the analysis of that mutant, we have discovered novel function of suberin: Suberin functions as an apoplastic barrier at the site of lateral root where Casparian strip is disrupted.
