Interaction between cell wall and plasma membrane via RGD motif is implicated in plant defense responses

A Kiba, M Sugimoto, K Toyoda, Y Ichinose, T Yamada, T Shiraishi

PLANT AND CELL PHYSIOLOGY 39 ( 11 ) 1245 - 1249 1998.11

Language：English Publisher：OXFORD UNIV PRESS

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.

Functional analysis of the putative cis-elements involved in activation by elicitor or UV and deactivation by suppressor in the promoter of a pea gene for phenylalanine ammonia-lyase (PSPAL1)

Y Murakami, Y Ichinose, T Shiraishi, T Yamada

PLANT AND CELL PHYSIOLOGY 38 ( 12 ) 1403 - 1408 1997.12

Language：English Publisher：JAPANESE SOC PLANT PHYSIOLOGISTS

The promoter of a pea gene for phenylalanine ammonia-lyase (PSPAL 1) contains Boxes II and IV that have synergistic effects on activation by fungal elicitor or UV light. Fungal suppressor suppressed the activation that was mediated not only by elicitor but also by UV in pea but activated the promoter in cowpea.

Superoxide generation in extracts from isolated plant cell walls is regulated by fungal signal molecules

PHYTOPATHOLOGY 87 ( 8 ) 846 - 852 1997.8

Language：English Publisher：AMER PHYTOPATHOLOGICAL SOC

Fractions solubilized with NaCl from cell walls of pea and cowpea plants catalyzed the formation of blue formazan from nitroblue tetrazolium. Because superoxide dismutase decreased formazan production by over 90%, superoxide anion (O-2(-)) may participate in the formation of formazan in the solubilized cell wall fractions. The formazan formation in the fractions solubilized from pea and cowpea cell walls was markedly reduced by exclusion of NAD(P)H, manganese ion, or p-coumaric acid from the reaction mixture. The formazan formation was severely inhibited by salicylhydroxamic acid and catalase, but not by imidazole, pyridine, quinacrine, and diphenyleneiodonium. An elicitor preparation from the pea pathogen Mycosphaerella pinodes enhanced the activities of formazan formation nonspecifically in both pea and cowpea fractions. The suppressor preparation from M. pinodes inhibited the activity in the pea fraction in the presence or absence of the elicitor. In the cowpea fraction, however, the suppressor did not inhibit the elicitor-enhanced activity, and the suppressor alone stimulated formazan formation. These results indicated that O-2(-) generation in the fractions solubilized from pea and cowpea cell walls seems to be catalyzed by cell wall-bound peroxidase(s) and that the plant cell walls alone are able to respond to the elicitor nonspecifically and to the suppressor in a species-specific manner, suggesting the plant cell walls may play an important role in determination of plant-fungal pathogen specificity.

Temporal and spatial pattern of expression of the pea phenylalanine ammonia-lyase gene1 promoter in transgenic tobacco

S Kawamata, K Shimoharai, Y Imura, M Ozaki, Y Ichinose, T Shiraishi, H Kunoh, T Yamada

PLANT AND CELL PHYSIOLOGY 38 ( 7 ) 792 - 803 1997.7

Language：English Publisher：JAPANESE SOC PLANT PHYSIOLOGISTS

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.
