Outline of Final Research Achievements |
Hydrangea is tolerant of acidic soils in which toxicity generally arises from the presence of the soluble aluminum (Al) ion. When hydrangea is cultivated in acidic soil, its resulting blue sepal color. The concentration of vacuolar Al in blue sepal cells can reach levels of approximately 15 mM, suggesting the existence of an Al-transport and/or storage system. We identified three transporter genes being responsible for Al hyperaccumulation; one vacuolar membrane-localized Al transporters genes HmVALT and two plasma membrane-localized ones, HmPALT1 and HmPALT2. HmVALT and HmPALT1 are both members of the aquaporin family, HmPALT belongs to anion permease family. The localization of each protein was confirmed. Immunoblotting results indicated that HmVALT and HmPALT2 are expressed all the tissues, but HmPALT2 was only in sepals. The overexpression of HmVALT in Arabidopsis thaliana conferred Al-tolerance and those of HmPALT1, 2 becomes Al-sensitive.
