The cDNA clones encoding rab type (INR134 and ELR19) and rac type (ELR26) small GTP-binding proteins were isolated from Ascochyta rabiei-inoculated chickpea leaves and the elicitor-treated cell cultures. Rac type ELR26 showed enhanced expression in inoculated leaves indicating correlation with the defense response. (C) 1999 Elsevier Science B.V. All rights reserved.

Induction of defense responses by synthetic glycopeptides that have a partial structure of the elicitor in the spore germination fluid of Mycosphaerella pinodes

A Kiba, T Takeda, T Kanemitsu, K Toyoda, Y Ichinose, T Yamada, T Shiraishi

PLANT AND CELL PHYSIOLOGY 40 ( 9 ) 978 - 985 1999.9

Language：English Publisher：OXFORD UNIV PRESS

A high molecular weight elicitor (>70 kDa) from spore germination fluid of a pea pathogen, Mycosphaerella pinodes, has a partial structure of beta-D-Glc-(1-->6)-alpha-D-Man-(1-->6)-D-Man, which is O-glycosidically attached to serine in the protein moiety. To elucidate the minimum structure for the elicitor activity to pea plants, the effects of nine glycopeptides including beta-D-Glc-(1-->6)-alpha-D-Man-(1-->6)-D-Man-O-Ser (No. 1) to [beta-D-Glc-(1-->6)-alpha-D-Man-(1-->6)-D-Man](3)-O-Ser(3)-Pro(3) (No. 9) on the infection by M. pinodes, superoxide generation and ATPase activity were measured. The glycopeptides [beta-D-Glc-(1-->6)-alpha-D-Man-(1-->6)-D-Man]-O-Ser(2)-Pro(2) (No. 3) to No. 9 induced rejection reaction of pea tissue against M. pinodes. The glycopeptides No. 3 to No. 9 also induced superoxide generation on uninjured pea leaves. Moreover, the glycopeptides No. 3 to No. 9 induced in vitro the activation of cell wall-bound ATPase and superoxide generation system in the protein fraction solubilized from pea cell wall. The results indicate that the synthetic glycopeptides, No. 3 to No. 9, are available to analyze the signal transduction cascade leading to defense responses and the receptor for the elicitor.

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.
