Biofertilizers containing high-density plant growth-promoting bacteria are gaining interest as a sustainable solution to environmental problems caused by eutrophication. However, owing to the limitations of current investigative techniques, the selected microorganisms are not always preferred by the host plant, preventing recruitment into the native microbiota or failing to induce plant growth-promoting effects. To address this, five nitrogen-fixing bacteria previously isolated from water yam (Dioscorea alata L.) plants and showing dominant abundance of 1% or more in the water yam microbiota were selected for analysis of their plant growth-promoting activities when used as a synthetic bacterial inoculant. Water yam cv. A-19 plants were inoculated twice at 10 and 12 weeks after planting under greenhouse conditions. Bacterial communities in root, rhizosphere, and bulk soil samples were characterized using high-throughput 16S rRNA amplicon sequencing. Compared with non-inoculated plants, all bacterial communities were significantly altered by inoculation, mainly at the genus level. The inoculation effects were apparently found in the root communities at 16 weeks after planting, with all inoculated genera showing dominance (in the top 35 genera) compared with the control samples. However, no significant differences in any of the growth parameters or nitrogen contents were observed between treatments. At 20 weeks after planting, the dominance of Stenotrophomonas in the inoculated roots decreased, indicating a decline in the inoculation effects. Interestingly, only the Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium clade was dominant (>1% relative abundance) across all samples, suggesting that bacteria related to this clade are essential core bacteria for water yam growth. This is the first report on addition of a synthetic nitrogen-fixing bacterial community in water yam plants showing that native bacterial communities can be replaced by a synthetic bacterial community, with declining in the effects of Stenotrophomonas on the modified communities several weeks after inoculation.

アセチルコリンとアセチルコリンエステラーゼの気孔運動に対する影響

野生型タバコの気孔開閉へのAChの影響と、アッケシソウAChE過剰発現タバコ(SeAChEタバコ)の表現型を調べた。野生型タバコにAChのみを与えても気孔開度は変化しないが、気孔閉鎖誘導物質アブシジン酸(ABA)とAChを同時に与えた場合、ABAによる気孔閉鎖が緩和された。対照的に、SeAChEタバコでは気孔開度が常に低下していた。AChはABAシグナル系を抑制する効果を持ち、SeAChEタバコでは内在性AChが分解されることで、ABA感受性が高まり気孔閉鎖が促進されていることが考えられた。

トウモロコシAChEのアミノ酸配列と77%および66％の相同性を有する2種類のイネAChEホモログ(rice AChE1およびAChE2)を発見し，イネにおいて各ホモログ遺伝子を植物バイオテクノロジー技術で過剰発現およびノックダウンした．Rice AChE1およびAChE2を過剰発現した形質転換イネは，ベクターコントロールと比較して極めて高いAChE活性を示した．そのため，両rice AChEホモログ遺伝子はイネにおけるAChE遺伝子であり，イネには2種類のAChEアイソザイムが存在することが示唆された．また，rice AChE1およびAChE2を過剰発現およびノックダウンした形質転換イネを用いて，熱および重力などの環境ストレスに対する両AChEの応答を比較検討した．
