1Comparison of Leptosphaeria biglobosa-induced and chemically induced systemic resistance to L.maculans in Brassica napus显示文摘Brassica napus(cv.Madrigal)seedlings pre-treated with ascospores of Leptosphaeria biglobosa or foliar sprays of either acibenzolar-S-methyl(ASM)or menadione sodium bisulphite(MSB)were chal- lenge inoculated with L.maculans ascospores and assessed for phoma leaf spot development and tissue morphology and gene expression responses to infection.Rates of increase in phoma leaf spot area 8―21 d after challenge inoculation were significantly greater on water pre-treated plants than on plants pre-treated with L.biglobosa,ASM or MSB on both pre-treated leaves(local effect)and younger leaves without pre-treatment(systemic effect).Ninety-six h after challenge inoculation,the invasive hyphae of L.maculans were encircled by rings of necrotic mesophyll cells on leaves pre-treated with L. biglobosa,ASM or MSB but not those pre-treated with water.Quantification of transcript levels of genes commonly used as markers of the major defence signalling pathways(PDF1.2,PR-1,NPR1,APX, CHB4)0–96 h after L.maculans challenge inoculation showed expression patterns indicating prefer- ential activation of the jasmonate/ethylene pathway and involved induction of NPR1 locally and sys- temically in leaves of plants pre-treated with L.biglobosa ascospores.LIU ShengYi LIU RenHu Akinwunmi O.
