    Hydroxyproline (Hyp) O-arabinosylation is a posttranslational modification that is prominent in extracellular glycoproteins in plants. Hyp O-arabinosylation is generally found in these glycoproteins in the form of linear oligoarabinoside chains and plays a key role in their function by contributing to conformational stability. However, Hyp O-arabinosyltransferase (HPAT), a key enzyme that catalyzes the transfer of the L-arabinose to the hydroxyl group of Hyp residues, has remained undiscovered. Here, we purified and identified Arabidopsis HPAT as a Golgi-localized transmembrane protein that is structurally similar to the glycosyltransferase GT8 family. Loss-of-function mutations in HPAT genes cause pleiotropic phenotypes that include enhanced hypocotyl elongation, defects in cell wall thickening, early flowering, early senescence, and impaired pollen tube growth. Our results indicate essential roles of Hyp O-arabinosylation in both vegetative and reproductive growth in plants.

    Arabinosylation of hydroxyproline (Hyp) is a posttranslational modification often found in secreted peptide signals in plants. The physiological importance of this modification was highlighted by the finding that CLAVATA3 (CLV3), a key peptide signal for regulating the fate of stem cells in shoot apical meristem (SAM) in Arabidopsis, contains three L-arabinose residues linked via linear β-1,2-linkages. However, understanding the functions and properties of arabinosylated peptides have been hindered by difficulties in synthesizing the complex arabinose chain. Here we report the stereoselective total synthesis of β-1,2-linked tri-arabinosylated CLV3 peptide ([Ara3]CLV3). Chemically synthesized [Ara3]CLV3 restricted stem cell activity more effectively than did unmodified CLV3 peptide. Comparison of mono-, di- and tri-arabinosylated CLV3 glycopeptides revealed that the biological activity increased progressively as arabinose chain length increased. Thus, arabinose chain length of CLV3 is important for its biological activity. NMR spectroscopy and NOE-based structure calculations further revealed the structural impact of the arabinose chain on peptide conformation. The arabinose chain of [Ara3]CLV3 extends toward the C-terminal end of the peptide, and its non-reducing end is positioned proximal to the peptide backbone. Consequently, the arabinose chain causes distinct distortion in the C-terminal half of the peptide in a highly directional manner. The established synthetic route of [Ara3]CLV3 will greatly contribute to our understanding of the biology and biochemistry of arabinosylated peptide signals in plants.

    Leucine-rich repeat receptor kinases (LRR-RKs) comprise the largest subfamily of the transmembrane receptor kinases in plants. In several LRR-RKs, a loop-out region called an island domain that intercepts the extracellular tandem LRRs at a position near the transmembrane domain constitutes the ligand-binding pocket, but the absence of the island domain in numerous LRR-RKs raises questions about which domain specifically recognizes the corresponding ligands in non-island domain-carrying LRR-RKs. Here, we determined by photoaffinity labeling followed by chemical and enzymatic digestion that BAM1, a CLV1/BAM family LRR-RK whose extracellular domain is comprised of 22 consecutive LRRs, directly interacts with the small peptide ligand CLE9 at the LRR6-8 region that is relatively distal from the transmembrane domain. Multiple sequence alignment and homology modeling revealed that the inner concave side of LRR6-8 of the CLV1/BAM family LRR-RKs is slightly deviatory from the LRR consensus. Supporting our findings, the clv1-4 mutant carries a missense mutation at the inner concave side of LRR6 of CLV1, and introduction of the corresponding mutation into BAM1 resulted in complete loss of ligand-binding activity. Our results indicate that ligand recognition mechanisms of plant LRR-RKs are more complex and diversified than anticipated.

    Peptidomics is a challenging field in which to create a link between genomic information and biological function through biochemical analysis of expressed peptides, including precise identification of post-translational modifications and proteolytic processing. We found that secreted peptides in Arabidopsis plants diffuse into the medium of whole-plant submerged cultures, and can be effectively identified by o-chlorophenol extraction followed by LC-MS analysis. Using this system, we first confirmed that a 12-amino-acid mature CLE44 peptide accumulated at a considerable level in the culture medium of transgenic plants overexpressing CLE44. Next, using an in silico approach, we identified a novel gene family encoding small secreted peptides that exhibit significant sequence similarity within the C-terminal short conserved domain. We determined that the mature peptide encoded by At1g47485, a member of this gene family, is a 15-amino-acid peptide containing two hydroxyproline residues derived from the conserved domain. This peptide, which we have named CEP1, is mainly expressed in the lateral root primordia and, when overexpressed or externally applied, significantly arrests root growth. CEP1 is a candidate for a novel peptide plant hormone.

    Phytosulfokine (PSK), an endogenous 5-amino-acid secreted peptide in plants, affects cellular potential for growth via binding to PSKR1, a member of the leucine-rich repeat receptor kinase (LRR-RK) family. PSK interacts with PSKR1 in a highly specific manner with a nanomolar dissociation constant. However, it is not known which residues in the PSKR1 extracellular domain constitute the ligand-binding pocket. Here, we identified the PSK-binding domain of carrot PSKR1 (DcPSKR1) by photoaffinity labeling. We cross-linked the photoactivatable PSK analog [125I]Ne-[(4-azidosalicyl)Lys5]PSK with DcPSKR1 using UV irradiation, and mapped the cross-linked region using chemical and enzymatic fragmentation. We also established a novel メon-column photoaffinity labelingモ methodology that allows repeated incorporation of the photoaffinity label to increase the efficiency of the photoaffinity cross-linking reactions. We purified a labeled DcPSKR1 tryptic fragment using anti-PSK antibodies, and identified a peptide fragment that corresponds to the 15-amino-acid Glu503-Lys517 region of DcPSKR1 by MALDI-TOF MS. Deletion of Glu503-Lys517 completely abolishes the ligand-binding activity of DcPSKR1. This region is in the island domain flanked by extracellular LRRs, indicating that this domain forms a ligand-binding pocket that directly interacts with PSK.

    Despite the large number of receptor-like kinases (RLKs) in plants, few of them have known specific ligands. Ligand fishing is one of the most challenging post-genomic technologies. Here, we report a strategy for functional immobilization of plant RLKs on microbeads via covalent linkage. Due to the high density of immobilized RLK, ligand-receptor interaction can be visualized at high sensitivity using fluorescent-labeled ligands under the confocal laser scanning microscope. Moreover, using receptor-based affinity chromatography system with RLK microbeads, the ligand of the receptor was directly retrieved at high purity from complex natural samples. Our RLK microbeads and receptor-based ligand fishing approach is a feasible alternative to conventional forward genetics and bioassay-based biochemical purification for identification of novel ligand-receptor pairs in plants.

    Phytosulfokine (PSK), a 5-amino-acid sulfated peptide that has been identified in conditioned medium of plant cell cultures, promotes cellular growth in vitro via binding to the membrane-localized PSK receptor. Here, we report that loss-of-function and gain-of-function mutations of the Arabidopsis PSK receptor (AtPSKR1) alter cellular longevity and potential for growth without interfering with basic morphogenesis of plants. Although mutant pskr1-1 plants exhibit morphologically normal growth until 3 weeks after germination, individual pskr1-1 cells gradually lose their potential to form calluses as tissues mature. Shortly after a pskr1-1 callus forms, it loses potential for growth, resulting in formation of a smaller callus than the wild-type. Leaves of pskr1-1 plants exhibit premature senescence after bolting. Leaves of AtPSKR1ox plants exhibit greater longevity and significantly greater potential for callus formation than leaves of wild-type plants, irrespective of their age. Calluses derived from AtPSKR1ox plants maintain their potential for growth longer than wild-type calluses. Combined with the present finding that PSK precursor genes are more strongly expressed in mature plant parts than in immature plant parts, the available evidence indicates that PSK signaling affects cellular longevity and potential for growth, and thereby exerts a pleiotropic effect on cultured tissue in response to environmental hormonal conditions.

    In recent years, numerous biochemical and genetic studies have demonstrated that peptide signaling plays a greater than anticipated role in various aspects of plant growth and development. A substantial proportion of these peptides are secretory and act as local signals mediating cell-to-cell communication. Specific receptors for several peptides were identified as being membrane-localized receptor kinases, the largest family of receptor-like molecules in plants. These findings illustrate the importance of peptide signaling in the regulation of plant growth, functions that were previously ascribed to the combined action of small lipophilic compounds referred to as メtraditional plant hormones.モ Here, we outline recent advances in the current understanding of biologically active peptides in plants, currently regarded as a new class of plant hormones.

    We have developed a novel procedure for concentrating sulfated peptides, as a front end to mass spectrometric analysis, based on ion-selective interaction of sulfate ions with anion exchangers. Ions with a higher charge and smaller solvated ion radius, such as sulfate ions, have higher retention in an ion exchanger, due to their greater degree of coulombic interactions. We tested the effectiveness of this approach for enrichment and identification of sulfated peptides, using a tryptic digest of bovine serum albumin spiked with model sulfated peptide (molar ratio, 20:1), and using a tryptic digest of bovine fibrinogen. Sulfated peptides are identified by mass spectrometry, in which both the molecular ion and its specific fragment ion produced by facile loss of SO3 are detected. In both experiments, sulfated peptides were strongly retained on the anion exchanger, and were eluted by higher concentrations of competing ion with minimum contamination of non-sulfated peptides. Using this procedure, we determined that the 13-amino-acid C-terminal peptide of the minor gユ chain of bovine fibrinogen contains sulfated tyrosine.

    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.

    In contrast to mobile animals, which can seek environments suitable for survival, immobile plants must use their flexible and efficient environmental response systems in order to respond rapidly to a variety of environmental changes. However, it remains unclear how plants control, assess, remember, and transmit information from the environment without brains or nerves. This area of study seeks answers to profound and longstanding biological questions. Our objective is to understand the mechanisms of plastic growth in response to the environment that are unique to plants. To this end, we seek to elucidate the long-distance signal transduction system ? which is completely different from those of animals ? that constitutes the local and autonomous environmental response system. Additionally, elucidation of the environmental memory system, which involves spatiotemporal caching of information via chromatin modifications, will be important for understanding plastic growth.

    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.
