Outline of Final Research Achievements |
Breading of waterlogging tolerant crops is required for improvement of quality and production in the converted filed from paddy in Japan. But, it is difficult to breed such a waterlogging tolerant crop because of the knowledges of waterlogging tolerance are limited. Barrier to radial oxygen loss is one of the key strategies for wetland plants to acclimate to waterlogged conditions. But, it is not known how to regulate the barrier formation under waterlogged conditions. Here, we identified abscisic acid (ABA) as inducer of hypodermal suberization and an ROL barrier in rice. Additionally, in barley that does not form barrier in natural, we succeed to make functional barrier to ROL in barley by an application of exogenous ABA. Our results imply the impotence of ABA localization and/or upstream signaling of ABA to give a function of ROL barrier in crops.
