Previous studies report that a dominant mutation in the OPEN STOMATA2 locus (OST2-2D) constitutively activates Arabidopsis PM H<sup>+<\/sup>-ATPase 1 (AHA1), which enlarges proton motive force for root nutrient uptake. However, the stomatal opening is also constitutively enhanced in the ost2-2D, causing drought hypersensitivity. To develop plants with improved nutrient acquisition and normal stomatal movement, we generated grafted plants (scion\/rootstock : Col-0 (WT)\/ost2-2D), and compared their growth and nutrient element content with those of control plants (WT\/WT) under two nutrient regimes. WT\/ost2-2D shoots had larger weights, rosette diameter, leaf blade area, and content of C, N, K, Ca, S, P, Mg, Na, Mn, B, Co, and Mo under nutrient-poor conditions compared with WT\/WT shoots. The root weights and primary root length were greater in WT\/ost2-2D plants than in WT\/WT plants under both nutrient conditions. These results suggest that root-specific activation of PM H<sup>+<\/sup>-ATPase enhances root nutrient uptake, which accelerates the plant growth under nutrient-poor condition. Our study presents a novel approach to improving nutrient uptake efficiency in crops and vegetable for the implementation of low-input sustainable agriculture.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kota Monden, Takehiro Kamiya, Daisuke Sugiura, Takamasa Suzuki, Tsuyoshi Nakagawa, Takushi Hachiya Abstract Pl [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"_links":{"self":[{"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/posts\/1499"}],"collection":[{"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/comments?post=1499"}],"version-history":[{"count":0,"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/posts\/1499\/revisions"}],"wp:attachment":[{"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/media?parent=1499"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/categories?post=1499"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/biochemistry.isc.chubu.ac.jp\/labo\/suzuki\/wp-json\/wp\/v2\/tags?post=1499"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
