    In these days of post genome era, metabolome studies attract more attention because the information on metabolites is the key data for so-called systems biology. To analyze the metabolites, mass spectrometry (MS) has been used mainly. However, the MS analysis is not always suitable to detect chemically-diversed metabolites. Therefore, we have been trying to establish NMR-based metabolomics approach. We have conducted the stable isotope labeling of plants, insects and mice, optimization of the extraction solvent for metabolites, building a chemical shift database, and constructing a semi-automtic signal assignment system, SpinAssign. In this talk, we will review these methodologic developments. We will also show the in vivo NMR measurements of Arabidopsis T87 cultured cells treated with ABA coupled with transcriptome analysis, and our attempt to detect metabolite changes in Ds insertion mutants. In addition, the future perspective and the potential of NMR metabolomics will be discussed.

    申請者らは、これまでに、植物を含む生物の経時的な成長状態や生理状態データを用いた非線形の形質予測モデルを構築することにより、環境要因や遺伝要因データから生体の動態を予測することが可能であることを実証した。一方で、予測に必要なデータの取得は、現段階ではコスト、時間、労力の点で効率が低く、より簡便に生体の生理状態に関するデータを取得する技術の開発が、基礎生物学のみならずその社会実装を実現する医学、農学においても不可欠である。本研究は、センサー開発においてコスト、操作、そして倫理的な点においてもハードルが低い植物を用いて、現在注目を集めているカーボンナノチューブ(CNT/SWNT)を利用して生理状態を把握する生体センサーを開発することを目指している。2021年度は、まずその観測システムの構築をおこなった。CNT/SWNTを用いて植物体内の活性酸素の変動を観測した報告を参考に、観測システム構築を行なった。これまでに、ほぼ同様のCNT/SWNTを利用した報告例が2報あるが、互いに異なるデータもあり、その検証や改良点の抽出も含めた検証実験との位置付けである。その結果、いずれの報告とも多々で相違が見受けられたものの、タバコ葉において傷害で誘導された活性酸素を観測することに、独自に構築したシステムを利用して成功した。また、CNT/SWNTをDNAで分散させる場合の条件検討も試みた。さらに、新たな物質のセンサー開発のために、生体分子のアプタマーとして報告があるDNAの情報を探索し、それらを合成しセンサー開発を進めた。この他、異なる薄幕を用いた基盤を利用したセンサーの開発についても検討を始めた。

    シロイヌナズナ短鎖ペプチドFEP1がどのように鉄欠乏応答の制御および鉄ホメオスタシスに関わっているかを明らかにするため、独自に作成したfep1欠損株やFEP1誘導発現形質転換株を利用して網羅的遺伝子発現解析を行った。詳細なデータ解析から、FEP1は維管束組織おける鉄欠乏応答で重要な役割を持つという知見を得た。また、FEP1類似遺伝子の植物界における保存性を調査し、維管束系を持つシダ植物にはFEP1類似遺伝子があるが、コケ植物には見当たらず、維管束組織との関わりが示唆された。シダ植物のFEP1様遺伝子はシロイヌナズナのものと同様鉄欠乏により誘導されるが、FEP1の活性に不可欠となるC末端の構造が異なっており機能については不明な点が多いが、ナス科植物にも同様の遺伝子が見つかっており、今後解析が必要である。さらに、FEP1周辺の機能因子の同定を目的に、FEP1を含む鉄欠乏応答遺伝子が恒常的に発現しているミトコンドリアpoly(A)制御関連変異株ahg2-1を背景にして、恒常的鉄欠乏応答形質の抑制変異を2系統獲得しているが、その一つの変異の同定に成功しRNA代謝関連の遺伝子が関与していることを明らかにした。一方、出芽酵母を用いた鉄欠乏応答制御の再構成を試み、植物で見られる応答がほぼ再現された。植物細胞を用いた実験で邪魔となる様々な二次的な影響を排除できる再構成系を用いて、今後構成因子に人為的な変化を導入し、その影響を調査することで精密な制御系の描出が可能と考えている。

    We identified short peptide genes that are actually translated by comprehensive transcript analysis and ribo-RNAseq analysis from the light-responsive treated plants of the grass model plant, Brachypodium distachyon. These included at least 100 short peptide genes that have not been reported before. To define the sequence set of non-coding RNA genes, we pooled RNA extracted from 21 tissues and analyzed the sequence data of a full-length cDNA library obtained by the cap-trapping method to identify about 10,000 non-redundant lncRNAs candidate sequences. We are attempting to create a discriminant model using some of the protein-coding genes and lncRNA candidate sequences as teacher data.

For this purpose, we investigated time series transcriptome and hormone datasets from a wild barley and a landrace accession, and revealed physiological changes along with their growth. We also analyzed genome-scale polymorphisms of diverse barley accessions. Moreover, using a legacy dataset of heading date of barely accessions and weather datasets, we developed statistical and/or machine learning-based models that estimate barely heading date.

    Abscisic acid (ABA) is a major phytohormone which regulates stress responses in plants. It had been demonstrated that protein phosphorylation is important in ABA signal transduction pathway, and we found several mRNA splicing factors as phosphoproteins in response to ABA. To elucidate splicing events in response to ABA, we performed RNA-seq analysis using Arabidopsis WT and srk2dei mutant, and identified over 170 splice variants were regulated by ABA and SnRK2. We are going to functional analysis of splice variants in ABA signaling, and RNA-seq analysis using Arabidopsis seeds in the same way.

    高等植物シロイヌナズナのミトコンドリアのmRNA安定制御に関わると考えられるpolyA特異的RNA分解酵素AHG2/PARNとpolyA付加酵素AGS1の機能解明を進めている。平成24年度は、主にahg2-1変異株のミトコンドリアの性状について解析を行った。そのひとつに、タンパク質の変動を調査した。核ゲノムコードのミトコンドリア局在タンパク質とミトコンドリアゲノムコードのタンパク質についてwestern blottingを行い、蓄積量を調査した。その結果、変異株ではミトコンドリアゲノムコードのタンパク質の増加が認められた。また、Blue-Native-PAGEを用いてミトコンドリア複合体のタンパク質量を調査した。その結果、変異株では、複合体の量が変動していることが確認された。このことから、mRNAの蓄積がタンパク質の増加を引き起こし、それがタンパク質複合体の量比を混乱することにより、呼吸に必要な複合体形成が阻害もしは不安定化を引き起こしていると推察される。また、ミトコンドリアDNA量、RNA量をqPCRを用いて、解析し、変異株では核あたりのミトコンドリア量が増加ていること、更にミトコンドリアDNAあたりのmRNA量が増加していることを明らかにした。また、予備実験としてAHG2, AGS1それぞれと相互作用するタンパク質の同定を試みた。それぞれのGFP結合タンパク質を発現する形質転換体からミトコンドリアを抽出し、供沈殿するタンパク質を質量分析装置を用いて、解析した。この懐石には理化学研究所の支援研究を利用させていただいた。その結果、それぞれ、ミトコンドリアで機能するRNA制御因子との相互作用が認められた。これらのデータを出すとともに、当該年度は論文の執筆を行った。現在、投稿した論文はrevise中で、まもなく投稿する予定である。

    昨年度までに、polyA特異的RNA分解酵素のAHG2の機能解析と、ahg2-1変異株の抑制変異遺伝子として分離されたpolyA付加酵素をコードするAGSI遺伝子の同定を進めてきた。本年度は、これら因子の標的分子の探索を中心に研究を進めた。ahg2-1変異を対象とした網羅的代謝物解析から、ミトコンドリア内転写物の蓄積が認められた。ミトコンドリア機能異常変異atphb3との比較解析から、ahg2-1変異はミトコンドリアに何らかの異常を持つことが示唆されたので、ミトコンドリア転写物いくつかのpolyA状態をPAT法により調査した。その結果、調べた転写物のほとんどでpolyA付加が認められた。一方野生株、ags1,atphb3ではpolyA付加は認められなかった。さらにinverse PCR法でnad7転写物のpolyA鎖長の状態を詳細に調べたところ、野生株ではpolyA付加が認められなかったが、ahg2-1では6~17bのpolyAを持つ転写物が確認された。また、ミトコンドリア転写物のいくつかについてNorthern法により蓄積量を調査したところ、調べたほとんどの転写物のahg2-1での蓄積が認められた。以上の結果から、AHG2およびAGS1の標的はミトコンドリア転写物と考えられる。これまで植物はもちろん他の真確生物に於いてもミトコンドリアmRNAのpolyA付加および除去に関わる因子双方が同定されている例はほとんどなく、その制御が不明であったため、この研究成果は意義が大きいと考える。
    しかしながら、これまでのところ、AHG2とAGS1はともにミトコンドリア局在を示す実験結果はない。これらのN末には、ミトコンドリア移行配列様構造が存在するので、これらを除いた改変遺伝子がahg2-1変異を相補できるかを検討し、ミトコンドリア局在と機能の関連を調査している。

    1.Phenotypic analysis using gek1 mutants.
    To investigate the effect of gek1 mutation on the metabolic pathway, we tried to detect the change in metabolites by muti-nuclear NMR measurement combined with ^<13>C, ^<15>N stable isotope labelling. The results showed that gek1 activated the amino acid metabolic pathway in the presence of ethanol more strongly than the wild type. Microarray analysis revealed that several stress inducible genes were upregulated more rapidly by ethanol treatment in the gekl mutant.
    2.Screening for gek1 suppressor mutants.
    Putative gek1 suppressor mutants, totally 34 lines, were isolated. We analyzed most of them and found they were adh mutants. We are going to analyze rest of them.
    3.Identification GEK1-interacting proteins.
    Three putative GEK1-interacting proteins were identified by yeast two-hybrid analysis. Two of them are Zn-finger proteins (#20,#24). The rest one is NFU2(#76) that is presumed to be involved in the formation of Fe-S cluster in chloroplasts. The subcellular localization and the analyses of disruption mutants (#24,#76) did not offer any clear link between these proteins and GEK1 so far.
    4.Recombinant GEK1 protein.
    A recombinant GEK1 protein expressed in E.coli was obtained. We investigated its activity to breakdown acetaldehyde in vitro. We tried several conditions, but failed to detect such activity. We obtained the recombinant protein of the Pyrococcus GEK1 homologus gene that is presumed to be more stable. We tried to detect the same activity but failed again. Therefore, we concluded that GEK1 does not have such activity. We also tried to see any activity to change the metabolite profiling. The extract from ^<13>C,^<15>N stable isotope labeled plants were reacted with the recombinant protein and measured by NMR. However, we could not detect any changes.

We used a ABA analogue, PBI-51, as a ABA binding inhibitor since this chemical has been reported to work as ABA binding inhibitor in Brassica napus. We tried to isolate mutants with two type of screening strategies. One is to search for mutants that seem to recognize PB151 as an ABA binding inhibitor. We isolated several candidates from 500,000 M2 seeds from EMS treated plants. However, these candidates turned out to be ABA insensitive mutants. The other strategy was to isolate mutants that seems recognize PB151 as ABA. In this screen, we isolated 8 independent lines from 400,000 M2 seeds from EMS treated plants. Those candidates show ABA-hypersensitivity, although these are not allelic to known ABA-hypersensitive mutants, eral or ein2.To increase the efficiency to isolate ABA receptor mutants, we thought out the strategy to use aba2 mutants, and isolated several dozens of candidates. ldentification of those mutated genes will surely contribute in our understanding on ABA siganling pathway. In the course to isolate ABA related mutants, we isolated a novel ethanol hypersensitiv mutant, gekol, from Arabidopsis. We identified the GEKO I gene by mapping and found it encoded a novel protein that conserved among plants and archea bacteria. GEKO I may play a pivotal role for plant sp ecific functions.

    1、酵母の高浸透圧応答性遺伝子の単離及び解析
    出芽酵母よりディファレンシャルスクリーニング法を用いて高浸透圧応答性遺伝子のcDNAクローン7つ(HOR1-HOR7)を単離した。これらのクローン構造解析を行い、HOR1,HOR3,HOR4,HOR5,HOR6がそれぞれglycerol-3-phosphate dehidrogenase,glucokinase,hexose,transporter,HSP12,P-type A TPaseをコードしていることが明らかにした。HOR2,HOR7は、今まで報告されていない遺伝子であった。さらにHOR2遺伝子と構造の類似してはいるが恒常的に発現している遺伝子、RHR2が酵母にはあることがわかった。このことから、HOR2及びRHR2の産物は酵母の生育にとって重要な働きを担っていると考えられたが、これらの遺伝子の破壊株は特徴的な表現型を示さなかった。
    様々な変異株のおけるこれらの7つのHOR遺伝子の発現様式を調べることで、情報伝達系路についてある程度示唆を得た。まず、高浸透圧応答には、いくつかの情報伝達経路があると予想された。また、いくつかの遺伝子はcAMPによっても制御されている可能性も示唆された。
    2、高浸透圧応答に関与する情報伝達突然変異体の単離
    単離した高浸透圧応答性遺伝子HOR2の発現調節領域を大腸菌由来のLacZ遺伝子に結合しレポーター遺伝子を構築した。このレポータ遺伝子は高浸透圧に応答した。このレポーター遺伝子を導入した酵母菌を用いて高浸透圧応答に異常の見られる突然変異株の分離を試みている。
