摘要： Lentinan (LNT), a complex polysaccharide with a-beta(1 -> 3)-linked backbone of D-glucose residues, has been reported to inhibit plant diseases. Our objective was to explore the efficacy and action mechanism of LNT used as a seed dressing to control sharp eyespot of wheat. Seed dressing promoted wheat growth. At control germination rates of 50%, 8g of LNT/100 kg of seeds of the Jimai 22, Shannong 23, and Luyuan 502 cultivars significantly increased seed germination to 54%, 52%, and 51%, respectively. Seven days after emergence, the heights and root activity - of wheat treated with LNT were significantly greater than those of controls. These effects were dose-dependent. At this time, the plant heights of Jimai 22, Shannong 23, and Luyuan 502 cultivars were 9.52, 8.52, and 10.52 cm, respectively, significantly higher than that of the controls. LNT prevented the developmet of wheat sharp eyespot. In the highly susceptible Jimai 22 cultivar, sharp eyespot development was reduced by 33.7%, 31.9%, and 30.4% at 7, 14, and 21 days after germination.J.NT some what increased' phenylalanine ammonia-lyase, peroxidase, and superoxide dismutase activity; reduced the malondialdehyde Content; increased chlorophyll a and b levels; and , enhanced the root vigor of wheat: The effects peaked 7 days after gerniination. LNT increased transcription of the genes encoding alternative oxidase '(AOX) and beta-1,3-glucanase (GLU), the salicylic acid signaling pathway-related gene NbPR1a, and the sharp eyeSpot resistance-related gene RS33. A significant dose-effect relationship was evident in terms of AOX transcription; We thus speculate that AOX may be the target gene.
