As know, development of necrotic lesions in the leaves of Oriental lily cultivar Star Gazer could be suppressed by the application of salicylic acid (SA). A cDNA sequence, named LsGRP1, coding for a 138-amino acid protein has been identified via suppression subtractive hybridization and differential screening. When the lily plants were treated with SA solution, the amount of LsGRP1 transcript analyzed by Northern blot hybridization increased. In the study of the relatedness between LsGRP1 and salicylic acid-induced disease resistance, agroinfiltration was applied for analysis of LsGRP1 transient expression in the leaves of Lilium cv. Star Gazer. In Northern blot hybridization, LsGRP1 transcript increased 72 hours after agroinfiltration of sense strand LsGRP1–expressing Agrobacterium tumefaciens EHA101 strain and more obviously 96 hours after agroinfiltraion. When the lily plants were treated with SA solution, the amount of LsGRP1 mRNA decreased in ‘Star Gazer’ leaves infiltrated with A. tumefaciens EHA101 strains expressing sense, anti-sense and hairpin LsGRP1, but the lesion numbers increased as compared to that in the control. These results showed that a gene silencing reaction was induced by introducing sense, anti-sense or hairpin LsGRP1, that abated the resistance of ‘Star Gazer’ leaves to gray mold disease. Thus, LsGRP1 playing an important role in salicylic acid-induced disease resistance of lily wasconcluded. Chao-Ying Chen 陳昭瑩 2006 學位論文 ; thesis 59 zh-TW |
