THE RELATIONSHIP BETWEEN SYSTEMIC RESISTANCE INDUCED BY PRUNING AND ACCUMULATION OF ANTIFUNGAL SUBSTANCES IN BARLEY SEEDLINGS

Infection by a compatible race of Erysiphe graminis f. sp. hordei on barley secondary leaves was significantly suppressed upon pruning of the primary leaves when E. graminis hordei was inoculated 3-12 h after the pruning, but it was rather enhanced during 15-21 h. The accumulation of antifungal substances was detected in hot ethanol extracts of barley seedlings from 15-27 h after pruning the primary leaves. Taking the time of the infection process of a challenger (E. graminis hordei) into consideration, timing of systemic resistance induced upon pruning coincided with the accumulation of antifungal substances.

SIGNAL MOLECULES INDUCING SYSTEMIC RESISTANCE AND SUSCEPTIBILITY IN BARLEY SEEDLINGS

T HIRAMOTO, R TOBIMATSU, N ABE, T SHIRAISHI, H OKU, T YAMADA, Y ICHINOSE

JOURNAL OF PHYTOPATHOLOGY-PHYTOPATHOLOGISCHE ZEITSCHRIFT 143 ( 1 ) 47 - 51 1995年1月

Exudate collected from the cut end of barley seedlings exhibited both activities that induced systemic resistance and susceptibility against Erysiphe graminis f. sp. hordei race Hh4 depending on the time after pruning. Exudates collected between 3-6 h after pruning showed maximum activity that induced systemic resistance, whereas those during 9-12 h conversely induced susceptibility in barley seedlings. The accumulation of antifungal substances in barley leaves correlates to the timing of induced resistance. The antifuntingal substances were water-soluble and severely affected the infection of E. graminis f. sp. hordei.

健全エンドウ苗中に存在する内生サプレッサーは, エンドウ褐紋病菌のエリシターで誘導されるピサチン蓄積を抑制し, 本サプレッサーで処理されたエンドウには非病原菌が感染できるようになる。本報告では, 抵抗反応の一つと考えられるキチナーゼとβ-1,3-グルカナーゼの活性化に及ぼす内生サプレッサーの影響について調べた。エンドウ, インゲン, ダイズの肛軸組織をエリシターで処理すると, 両酵素の活性化が誘導された。しかし, 内生サプレッサーの共存下には, 供試植物中エンドウでのみ活性増高が抑制された。ー方, インゲンおよびダイズでは, 内生サプレッサーの単独処理においても, 両酵素の活性増高が誘導された。これらの結果は, 植物防御応答に対する内生サプレッサーの作用が種特異的であり, 作用様式において褐紋病菌サプレッサーと酷似することを示している。

ORGANIZATION OF THE GENES ENCODING CHALCONE SYNTHASE IN PISUM-SATIVUM

C AN, Y ICHINOSE, T YAMADA, Y TANAKA, T SHIRAISHI, H OKU

PLANT MOLECULAR BIOLOGY 21 ( 5 ) 789 - 803 1993年3月

To analyze the regulation of defense-related genes by signal molecules produced by phytopathogens, we isolated genes that encode chalcone synthase (CHS) in Pisum sativum. We have obtained seven independent genomic clones that contain at least seven classes of CHS genes, identified by the hybridization analysis to CHS cDNA and by the restriction mapping analysis. Two of the genomic clones (clone 5 and 6) each contain two CHS genes in a tandem repeat. The nucleotide sequence analysis of CHS genomic clone 5 revealed that PsCHS1 and PsCHS2 were corresponding genes of the CHS cDNA clones, pCC6 and pCC2, respectively, as reported earlier. Both genes are interrupted by a single intron of 88 nucleotides with identical sequences, although exonic sequences and 5'-flanking sequences are divergent. Nucleotide sequences of the introns in five other classes of CHS genes showed that three classes had an intron of 87 nt with a striking homology to each other, but that the intron of the other two classes of CHS genes showed heterogeneity both in size and nucleotide sequence. 5'-upstream regions of PsCHS1 and PsCHS2 did not show sequence homology except the 31 bp identical sequence that contains the CCTACC motif resembling the box-1 sequence. Both PsCHS1 and PsCHS2 genes are shown to be induced by fungal elicitor by a primer extension analysis and a transient transformation analysis using pea protoplasts prepared from suspension cultured-cells.
