Integrin- and vitronectin-like proteins were found to exist in the pea plasma membrane and cell wall, respectively. The hexapeptide GRGDSP but not GRGESP inhibited either the binding of cell wall protein(s) to plasma membrane protein(s) or the defense response. A possible role of linkage via RGD motif in plant defenses is discussed.

Effects of elicitor and suppressor from a pea pathogen, Mycosphaerella pinodes, on Pl etabolism in pea plasma membrane were examined in vitro. The elicitor induced rapid phosphorylation of phosphatidylinositols as well as production of lysophospholipid in plasma membranes, but these responses were severely inhibited by the suppressor. These results indicate that a membrane-associated phospholipase A is regulated coordinately by fungal signals, together with Pl metabolism, and that it may participate in signal transduction pathways leading to defense responses. To evaluate a possible rote of phospholipase A activation in induction of a pea defense response, the effect of free fatty acid on induction of a phytoalexin accumulation was also examined. When pea leaves were treated with linoleic- or linolenic acid, most commonly released in plant cells by phospholipase A, the accumulation of pisatin was induced even in the absence of the elicitor. It is, therefore, conceivable that free fatty acid(s) released from plasma membrane is also implicated in the early stage of elicitor-signal transduction in pea.エンドウの上胚軸組織により分離した原形質膜画分を褐紋病菌の生産するエリシターで処理すると、ホスファチジルイノシトールリン脂質の急速なリン酸化とリゾリン脂質の生成が誘導されたが、同菌より調製したサプレッサーの共存下では双方とも著しく阻害された。本結果は、ポリホスホイノシチド代謝系と同調的に作動するホリパーゼA活性化が存在すること、さらに、原形質膜における病原菌シグナルの受容・応答には複数の資質代謝系が介在する可能性を示唆している。一方、ホスホリパーゼAの活性化の役割を調べる目的で、本酵素によって原形質膜から生成されると考えられる脂肪酸(リノール酸ならびにリノレン酸)をエンドウ葉に処理したところ、エリシターの非存在下においてもファイトアレキシンであるピサチンの生成が誘導されることが示された。以上から、ポリホスホイノシチド代謝系と同調的に働くホスホリパーゼAがエリシターシグナルの初期伝達に深く関連しているものと考えられた。

エリシターの認識とそのシグナル伝達機構を解析する目的で, エンドウ上胚軸組織におけるジアシルグリセロール生成量を調べた。この結果, エリシター処理組織においては, 処理後1分以内に急速なジアシルグリセロールの生成が認められたが, ホスホリパーゼCの阻害剤であるネオマイシンやエンドウ褐紋病菌のサプレッサーの共存下には, その生成は著しく阻害された。この結果は, 細胞内におけるイノシトール3リン酸を定量した既報の結果と一致し, ホスホリパーゼC活性の一過的上昇がエリシターシグナルの伝達に必須であることを強く示唆する。このことは, 細胞内のジアシルグリセロール濃度の上昇を引き起こすジアシルグリセロールキナーゼ阻害剤(R59022)で処理された組織では, エリシターの処理によって誘導されるファイトアレキシンの生成量が約4倍に増加することからも支持された。

Genes encoding phenylalanine ammonia-lyase (PAL) form a small multigene family with at least three members in pea. Tissue-specific expression of the promoter of a member of PAL gene family (PSPAL1) was investigated in the transgenic tobacco transformants carrying the different modes of chimeric fusion between the PSPAL1 promoter and a bacterial beta-glucuronidase (GUS) gene. In stems, at least, strict correlation was found between steady-state levels of Gus-mRNA and enzyme activity. Significantly high level of GUS activity was observed in roots, particularly in meristematic tissues and the pigmented region of petals of transgenic tobacco carrying the translational fusion type B (-1,394 to +140 of PSPAL1 connected to Gus), followed by moderately high level of GUS activity carrying the translational fusion type A(-1,394 to +117). GUS expression in tissues of mature leaves, however, was very low in these constructs. Extremely low GUS activity was observed in the transformants of transcriptional fusion type (-1,394 to +5), whilst no activity was detected carrying non-transcription fusion type (-1,394 to -27). Furthermore, the pattern of the PSPAL1 expression was characterized in response to pathogen ingress and woundings in transgenic tobacco carrying the translational fusion type B. Woundings itself triggered marked expression of PSPAL1-driven GUS expression at the wounded sites. Inoculation of nonpathogens, Phytophthora capsici, P. boehmeriae and Erisiphe graminis f. sp. hordei, both caused rapid and very clear GUS expression zone along with the development of hypersensitive cell death area where callose was accumulated, however, the inoculation of a pathogen, P. nicotiana caused slow and hazy GUS expression zone along with the lesion development. These results suggest that the expression of pea PSPAL1 promoter is regulated in a similar fashion, at least in a part, in pea and transgenic tobacco, under the plant development and various environmental cues.
