摘要

The effects of arachidonic acid (AA) on the development of viral infection and the activity of phytohemagglutinins in Nicotiana tabacum L. plants were studied. Cv. Samsun NN was used, which displayed a genotypically determined hypersensitive response to tobacco mosaic virus (TMV) infection. When tobacco leaf disks were treated with 10(-9) to -10(-7) M AA, viral reproduction was suppressed by 90-100%. The AA concentration of 10(-8) M was optimal for the improvement of plant virus resistance. Tobacco leaves maintained virus resistance for at least two weeks. Both AA treatment and TMV inoculation were accompanied by an enhanced lectin activity, which may indicate the involvement of lectins in the development of plant defense responses. Lectin accumulation was observed in the intact plants developing systemic resistance and in the detached leaves characterized by local resistance.
