Characterization of Soft-rot-resistant Amorphophallus konjac and Preliminary Analysis of the Resistance Mechanism
摘要
Abstract
Amorphophallus konjac plants with strong resistance to soft-rot disease were identified from the A.konjac field in Changyang,Yichang.Karyotype analysis showed that the number of chromosomes in resistant plants were consistent with that in common A.konjac plants (susceptible),and both were 2n=26.Resistant plants were compared with susceptible A.konjac plants for disease resistance.Soft-rot-resistant plants showed stronger resistance against Erwinia carotovora var.carotovora than susceptible plants did.ELISA revealed hormone levels induced within 30 h after infection with E.carotovora.However,susceptible plants showed higher levels of jasmonate and salicylic acid than resistant plants did.These results imply a different disease resistance mechanism in resistant A.konjac plants,which can be examined by further studies.关键词
