tolerance or Al-sensitivity yet to be clarified. We previously reported Japonica rice (Oryza
sariva L.) cultivar Rikuu-20 as Al-sensitive, whereas a closely related cultivar that is a
descendant of Rikuu-20, Rikuu-132, was Al tolerant. The objective of the present study was
to clarify the role of plasma membrane lipid layer for Al tolerance in rice. The previously
stated two cultivars were compared to determine mechanisms underlying variations in Al …
