動き回ることのできない植物は土壌中の窒素などの栄養源に代表されるような空間的に不均一な環境に適応する必要があり、また光合成を行なう気相と栄養吸収を行なう土相という異なる環境空間にまたがって生育するため、地上部と地下部の双方において変動する環境情報を時空間的に統合して適応する必要に迫られる。本研究では、これらの不均一変動環境への適応過程に関わる長距離シグナル伝達に着目し、その分子群の同定や情報統御メカニズムの解明を目指す。
動き回ることのできない植物は，土壌中の窒素などの栄養源に代表されるような空間的に不均一な環境に適応する必要がある．また光合成を行なう気相と栄養吸収を行なう土相という異なる環境空間にまたがって生育するため，地上部と地下部の双方において変動する環境情報を時空間的に統合して適応する必要に迫られる．本研究では，これらの不均一変動環境への適応過程に関わる長距離シグナル伝達に着目し，その分子群の同定や情報統御メカニズムの解明を目指している．
1．葉から根に移行する窒素要求シグナルCEPD/CEPDL2が，どのように根でターゲット遺伝子群の発現を誘導するのかを明らかにするために，CEPDL2-GFPをベイトとしたCo-IP/MS解析を行なった結果，転写因子であるTGA1/4が単離された．CEPD/CEPDL2はコアクチベーターとしてTGA1/4を介したターゲット遺伝子群の転写活性化に関わっていると考えられる．
2．CEPD/CEPDL2ペプチドはシロイヌナズナで21個の遺伝子からなるファミリーを形成しているが，その中にCEPDとは逆に過剰発現で窒素吸収を抑制する分子群GrxS1-S8を見出した．これらは，CEPD/CEPDL2と拮抗して窒素恒常性に関わっている可能性が考えられたため，両者の関係性を遺伝子レベルおよびタンパク質レベルで解析している．
3．LRR-RKサブファミリーXIに残された3つのオーファン受容体が，ペプチドホルモンPSYの認識に関わっていることを突き止め，成長とストレス応答との切り替えに関わることを明らかにした．自然界では植物は時空間的に不均一なストレスにさらされているが，ダメージを受けた領域の周辺で局所的にストレス応答が誘導される新たなしくみを見出した．
全身的窒素要求シグナリングでは，これまでに道管移行ペプチドCEP-受容体CEPR-篩管移行ペプチドCEPD-フォスファターゼCEPHなどの主要コンポーネントが明らかになっているが，①窒素欠乏の根におけるCEP誘導のメカニズム，②葉におけるCEPR活性化からCEPD誘導までの分子機構，③根に移行したCEPDが根圏の窒素状況依存的に硝酸取り込みを活性化するメカニズム，などについてはまだ明らかになっていない．それぞれに関わる分子群を見出すことは全身的窒素要求シグナリングを理解する上で不可欠である．
今回の結果から，CEPD/CEPDL2は根で転写因子TGA1/4と直接結合し，コアクチベーターとして下流遺伝子群の発現を制御していることが明らかになった．この知見は，③のメカニズムを解明する上で，大きな前進である．また，CEPD/CEPDL2とは逆に葉の窒素十分を根に伝えるシグナルGrxS1-S8の存在も明らかになったことから，植物体の窒素恒常性は，両者のバランスで維持されている可能性が高い．また，①と②の解析では，トランスクリプトームやリン酸化プロテオミクス，共免疫沈降などによってシグナリングに関与する分子群の探索を進めており，得られた候補分子について欠損株の表現型観察やCEP応答性を解析している．
「現在までの進捗状況」に記した①から③の各項目の研究を引き続き進めていく．特にCEPD/CEPDL2が結合する転写因子を同定できたことや，CEPD/CEPDL2と機能的に拮抗するGrxS1-S8が見出されたことは，植物の窒素恒常性メカニズムの理解に大きな前進であるため，これらの相互関係の解明を中心に研究を進めていく．

The following results were obtained by a new approach that focuses on molecules and traces them back to mechanisms. (i) the discovery of a novel peptide hormone PSY and its receptor PSYR that controls stress response and growth switching in plant cells; (ii) the discovery of the phloem-mobile peptide signal CEPDL2, which communicates leaf nitrogen demand to the roots; (iii) the discovery of the protein phosphatase CEPH, which acts downstream of CEPDL2 and activates the nitrate transporter NRT2.1; and (iv) discovery of proteases that cleave peptide ligands that induce immune response from flagellin, the major protein constituting the bacterial flagellum.

This new area of scientific study began with the goal of performing an integrated analysis of the dynamic environmental response control system in plants. This analysis includes clarifying the flexible and ingenious local and autonomous environmental response system evolved by immobile plants, which is completely different from those of animals, as well as a new spatiotemporal perspective. Specifically, we seek to analyze the long-distance signal transduction system of plants, as well as the environmental memory system that caches information via chromatin modifications. Actually, we have obtained exciting results regarding the dynamic environmental response control system in plants.

Nitrogen (N) is an essential macronutrient that plays a crucial role throughout plant development, but soil nitrate availability fluctuates temporally and spatially. We identified that N starvation-induced peptide CEP acts as a root-derived ascending N-demand signal. CEP is recognized in the shoot by CEP receptor, that leads to the production of non-secreted polypeptide, CEPD. CEPD acts as a descending signal to the root and ultimately upregulates nitrate transporter NRT2.1 gene in the roots. Thus, CEP induced on one side of the roots by local N starvation is able to mediate upregulation of NRT2.1 in the distant part of the roots. In addition to this, plants modulate the efficiency of root N acquisition in response to shoot N demand by CEPD-like 2, which is upregulated in the leaf vasculature in response to decreased shoot N status. Our findings provide new insights into the molecular basis of plant adaptation to a dynamically fluctuating N environment.

Our goal in this project is to uncover the mechanisms by which plant development is regulated through identification of novel peptide hormones and their specific receptors. In plants, small post-translationally modified peptides constitute the largest group of peptide hormones. We explored this type of peptide hormone by in silico gene screening coupled with biochemical and functional analysis, which led to the identification of two types of novel peptide hormones such as CEP family peptides regulating long-distance nitrogen demand signaling and CIF family peptides required for contiguous Casparian strip formation in roots. We also identified receptors for RGF family peptides involved in root meristem development.

ペプチドホルモンの翻訳後修飾のひとつであるチロシン硫酸化に関与する酵素（tyrosylprotein sulfotransferase: TPST）の同定に成功し，この酵素の欠損株では，根端の幹細胞が維持されず，根が極端に短くなることを見出した．さらに，この表現型の原因のひとつとなっていた新しいチロシン硫酸化ペプチドホルモン（root meristem growth factor: RGF）の同定にも成功した．RGFは，根端メリステム幹細胞ニッチの維持およびメリステム活性の制御に関与している．また，液体培地に分泌された微量の分泌型ペプチドの効率的な抽出・構造解析法を確立し，新規ペプチドホルモンの候補を複数見出した．この手法を応用したCLV3ペプチドの構造解析の過程で，Hyp側鎖への糖鎖付加（トリアラビノシル化）という翻訳後修飾を見出し，この修飾がCLV3の生物活性や受容体結合活性を高める重要な働きをしていることを突き止めた．
