    Summary

    Hakea laurina, a woody Proteaceae, naturally occurs in severely phosphorus (P)‐impoverished habitats in southwest Australia. It develops distinctive cluster roots that exhibit a high capacity for carboxylate exudation and acid phosphatase activity, contributing to its P acquisition. However, the molecular mechanisms underlying these physiological functions remain poorly understood.

    We explored the cluster‐root transcriptome using de novo RNA‐Seq and identified Hakea laurina Aluminum‐activated Malate Transporter 1 (HalALMT1), encoding an aluminum (Al)‐activated malate transporter induced in mature cluster roots. We characterized HalALMT1 through electrophysiological assays and overexpression in Arabidopsis thaliana, and localized HalALMT1 expression, acid phosphatase activity, and suberized boundaries in cluster roots.

    Differentially expressed genes highlighted multiple increased carboxylate‐related processes at cluster‐root maturity. HalALMT1 released malate, an activity further enhanced by exposure to Al3+. Notably, HalALMT1 was specifically expressed in mature cortex cells of cluster rootlets, which lack a suberized exodermis. Acid phosphatase activity was pronounced throughout the cluster rootlets, unlike in noncluster roots where it was limited to the epidermis and stele.

    Substantial malate release and acid phosphatase activity in the cortex cells in cluster rootlets, which lack a suberized exodermis, allowed massive exudation. This study sheds light on an exquisite P‐acquisition strategy of Proteaceae, enabling survival under extremely low P availability.

    <title>Abstract</title>
    Aluminum (Al)-tolerant tobacco cell line ALT301 derived from SL (wild-type) hardly exhibits Al-triggered reactive oxygen species (ROS) compared with SL. Molecular mechanism leading to this phenotype was investigated comparatively with SL. Under normal growth condition, metabolome data suggested the activation of glycolysis and lactate fermentation but the repression of the tricarboxylic acid (TCA) cycle in ALT301, namely aerobic fermentation, which seemed to be transcriptionally controlled partly by higher expression of genes encoding lactate dehydrogenase and pyruvate dehydrogenase kinase. Microarray and gene ontology analyses revealed the upregulation of th e gene encoding related to APETALA2.3 (RAP2.3)-like protein, one of the group VII ethylene response factors (ERFVIIs), in ALT301. ERFVII transcription factors are known to be key regulators for hypoxia response that promotes substrate-level ATP production by glycolysis and fermentation. ERFVIIs are degraded under normoxia by the N-end rule pathway of proteolysis depending on both oxygen and nitric oxide (NO), and NO is produced mainly by nitrate reductase (NR) in plants. In ALT301, levels of the NR gene expression (NIA2), NR activity and NO production were all lower compared with SL. Consistently, the known effects of NO on respiratory pathways were also repressed in ALT301. Under Al-treatment condition, NO level increased in both lines but was lower in ALT301. These results suggest that the upregulation of the RAP2.3-like gene and the downregulation of the NIA2 gene and resultant NO depletion in ALT301 coordinately enhance aerobic fermentation, which seems to be related to a higher capacity to prevent ROS production in mitochondria under Al stress.

    Under phosphorus (P)-deficient conditions, organic acid secretion from roots plays an important role in P mobilization from insoluble P in the soil. In this study, we characterized AtALMT3, a homolog of the Arabidopsis thaliana aluminum-activated malate transporter family gene. Among the 14 AtALMT family genes, only AtALMT3 was significantly up-regulated in P-deficient roots. AtALMT3 promoter::β-glucuronidase is expressed in the epidermis in roots, especially in root hair cells. AtALMT3 protein was localized in the plasma membrane and in small vesicles. Fluorescence of AtALMT3::GFP was not observed on the vacuole membrane of protoplast after lysis, indicating that AtALMT3 localizes mainly in the plasma membrane. Compared with the wild-type (WT) line, malate exudation in the AtALMT3-knockdown line (atalmt3-1) and overexpression line (atalmt3-2) under P deficiency were, respectively, 37% and 126%. In contrast, no significant difference was found in citrate exudation among these lines. The complementation of the atalmt3-1 line with AtALMT3 recovered the malate exudation to the level of the WT. Taken together, these results suggest that AtALMT3 localized in root hair membranes is involved in malate efflux in response to P deficiency.

    リン酸質肥料は作物生産に必須であるが、資源は涸渇に瀕しており、持続的な作物生産にはその問題の解決が必要である。低リン耐性を有する一部の植物は、クラスター根とよばれる小根が密集した根を形成する能力がある。このクラスター根は、根の表面積を増やし、難利用性リンの吸収を強化して適応するために形成されると考えられているが、その形成能と難利用性リンの供給能の詳細は未解明である。本研究ではシステムズ生物学アプローチ解析によるクラスター根の形態形成イベントの制御、爆発的な根分泌の誘導による難利用性リンからの供給能の解明に取り組む。
    これまでに、クラスター根形成種であるシロバナルーピンおよびHakea laurinaのRNA-seqデータなどを元にして複数の有機酸トランスポーター候補の同定に成功した。これらの候補遺伝子の発現量を調査したところ、低リン条件のクラスター根で顕著な発現誘導が確認された。また、シロバナルーピンのRNA-seqデータからクラスター根の発達へのエチレンの寄与が示唆されたことから、エチレン前駆体であるACCおよびエチレン合成阻害剤であるCo2+イオンを添加してその影響を評価した。その結果、エチレンはクラスター根を構成する小根の伸長停止に寄与するとともに、リン欠乏への発現応答にも関与していることが示唆された。
    新規なクラスター根形成種の探索を行うため、根のメタバーコーディングライブラリー作成のためのサンプル採集を進めた。クラスター根圏土壌細菌群集のメタバーコーディングを行うため、根圏土壌を採取し、アンプリコンシーケンスの準備を進めた。シロバナルーピンの根箱栽培を実施し、クラスター根におけるリン可溶化に関わる遺伝子発現および土壌中のリン形態を調査した結果、クラスター根の発達段階だけでなく根が形成された位置による違いが認められ、局所的に異なる機能を持つことが明らかとなった。

    植物に特異的なALMTファミリー・リンゴ酸輸送体の多様な生理現象に着目している.本研究課題では気孔の孔辺細胞で発現するALMT遺伝子に焦点をあて,その分子メカニズムを解析している.この「気孔ALMT輸送体」については,主にシロイヌナズナでのみ分子生物学的な知見が得られているが,タンパク質の機能領域や環境ストレス応答・シグナル伝達機構について,他の植物との相違が明確ではなかった.昨年度までに,トマトの気孔ALMTであるSlALMT11遺伝子を同定し,遺伝子発現抑制トマトの解析から,アポプラストのリンゴ酸応答した気孔閉口に関与することを明らかにした.
    本年度は,トマトとシロイヌナズナの気孔ALMT(SlALMT11とAtALMT12)について,アフリカツメガエル卵母細胞を用いた電気生理学的測定により,輸送機能領域を調べた.
    SlALMT11,AtALMT12共に,測定時の外液にリンゴ酸が存在下で,リンゴ酸放出に伴う電流パターンが(植物膜の静止電位である)-100 mV付近をピークにした「ベル型」を示した.また,共にタンパク質のC末端へのGFP融合させること,またはC末端側からアルファヘリックス構造までの約30アミノ酸配列の欠失により,「ベル型」パターンの消失がみられた.
    さらに,SlALMT11,AtALMT12と相同性を示す他植物由来ALMTタンパク質のアミノ酸配列の相同領域を比較した結果,C末端に酸性アミノ酸(アスパラギン酸又はグルタミン酸)が保存されていた.そこで,SlALMT11とAtALMT12のC末端の酸性アミノ酸を欠失したコンストラクトを作製し,電気生理的に輸送機能を調べたところ,「ベル型」パターンの消失がみられた.これらの結果から,C末端の一つの酸性アミノ酸が輸送体の膜電位依存性を制御しており,植物の気孔タイプALMTに共通した特徴であることが示唆された.

    In this study, two tomato ALMT-family malate transporter genes expressed in fruit and leaf were analyzed. The SlALMT gene in fruit was found to be expressed in the vascular bundles during the early stage of maturation. The SlALMT transporter exhibited the efflux of malate as well as dicarboxylic acids, and the influx of nitrate and chloride. The transgenic suppresser were constructed and examined several metabolites. Malate content in mature green fruit was not different between wild type and the suppressor lines. The SlALMT gene in leaf was found to be expressed in guard cells. The SlALMT transporter exhibited the malate-efflux activated by extracellular malate concentration.

    This study aimed (1) to clarify the formation of cluster roots and their function and (2) to survey the possibility to utilize on crop production and their ecological functions using cluster root-forming plants, which have super-tolerant to low-P environments. It was suggested that the sparingly soluble organic P fraction in the rhizosphere soil was mobilized by the cluster roots. It was also suggested that the nutrient accumulation pattern of neighbor plants of cluster root-forming plants was altered by rhizosphere sharing with cluster roots. P accumulation of main crop intercropped with cluster root-forming plants was higher than monocropped plants. This result suggests a possibility to decrease of usage of P fertilizer by intercropping of cluster root-forming plants.

    A major inhibitory factor of crop production in acidic soils is aluminum (Al) ion. Using cultured tobacco cell lines and seedlings of tobacco, we found (1) a novel avoidance mechanism of ROS production in mitochondria by repression of TCA cycle but enhancement of fermentations in cytosol even under normoxia, which is similar to the Warburg effect reported in cancer cells, (2) an increase in Al tolerance by the over-expression of sucrose transporter in the plasma membrane, and (3) the involvement of vacuolar processing enzyme in cell death mechanism under Al stress.

    Aluminum ion is a major factor to inhibit plant growth in acidic soils. Mechanisms of aluminum toxicity and tolerance in plants were examined, focusing on energy(sugar) metabolism in mainly cultured tobacco cell lines and tobacco plant. Our results suggest a novel aluminum tolerant mechanism which shifts energy metabolism from respiration to lactate fermentation so that the production of reactive oxygen species(ROS) via dysfunction of mitochondria under aluminum stress could be avoided.

    The mechanisms for the expression and function of aluminum-activated malate transporter (ALMT1) of wheat were analyzed. We demonstrated that the variation of the upstream sequence of ALMT1 is strongly correlated to the aluminum sensitivity of wheat, and that three acidic amino acids within hydrophilic C-terminal domain of ALMT1 is required for the activation of transport function by aluminum. Furthermore, we found that the functions of several ALMT homologues in Arabidopsis are related to aluminum resistance and closing stomata, suggesting that ALMT proteins comprise a family of anion transporters, possessing diverse functions.

    A major factor to inhibit crop production in acidic soils is aluminum (Al) ion. Thus the elucidation of mechanisms of Al toxicity and tolerance will be expected to provide basic information necessary for breeding Al-tolerant crops. In this study, these mechanisms were investigated in both cultured cell system and whole plant systems, focusing on sugar metabolism which is necessary for cell elongation and root growth. The findings are as follows:
    1. Aluminum ion inhibits sugar uptake and stimulates sugar consumption in tobacco cells, which could lead to an increase in water potential and then the inhibition of cell elongation.
    2. In a whole plant system, the translocation of photoassimilates is stimulated towards the root under Al stress.
    3. The Al-induced cell death process is different from the sugar-starvation-induced cell death, and involves the production of reactive oxygen species, vacuolar collapse and changes of cytosolic calcium concentration in tobacco cells.
    4. Another physiological meaning of the Al-triggered malate secretion in wheat is to maintain the growth capability of root under Al stress. The repetitive sequences in the upstream of the ALMT1 gene, encoding the Al-activated malate transporter, seem to control the expression level of the gene. The membrane topology of ALMT1 protein was elucidated.
    5. Isolation and characterization of Al-sensitive mutants of rice at germination stage were performed.
    These results indicate novel Al symptoms related to energy metabolism. Molecular and genetical aspects of these symptoms will be studied, and the roles of Al will be elucidated in the sugar metabolism related to the organic acid secretion to support Al tolerance and the sugar metabolism related to germination.

    In order to isolate Al tolerant gene, we screened 16,000 activation tagging line of Arabidopsis and found 20 candidates lines. However, almost all candidate lines showed the multiple copy of the tag in chromosome. Only one lien (#355-2) showed an insertion of single copy at upstream region of chromosome 1.
    To vivify the role of mitochondria on the molecular mechanism of Al toxicity and tolerance, we used Al sensitive tobacco line(SL) and tolerant line (ALT301). We observed a decrease in State III and IV respiration in both SL with reduced rate of inhibition in ALT301.
    In SL,AOX- and CYT-respirations were inhibited but AOX-respiration in ALT301 increased by 15%. Production of ROS in mitochondria of SL increased but it deceased in ALT301 under Al stress.
    We succeeded to isolate novel gene (ALMT1) encoding Al activated malate transporter from near isogenic Al tolerant wheat (ET8). ALMT1-1 were common in Al tolerant ET8 and Atlas 66. ALMT1-2 were common in Al sensitive ES8 and Scout 66. The difference between ALMT1-1 and ALMT1-2 were 6 bases (2 amino acid residues). ALMT1-1 segregated well to Al tolerance of wheat, suggesting that ALMT1-1 corresponds to Al tolerance (Alt 1) gene.
    Heterogous expression of ALMT1 in Xonopus oocytes, rice and cultured tobacco ells conferred an Al-activated malate efflux. We generated transgenic barley plants expressing ALMT1. ALMT1 expression in barley conferred an Al-activated efflux of malate. The transgenic barley showed a high level of Al tolerance when grown in both hydroponics culture and on acid soils.
