چکیده    Ethylene has an important function in plant growth and development. ethylene production generally increases in response to pathogen attacks and other environmental stress conditions. the synthesis of this phytohormone is regulated by two enzymes,acc synthase (acs) and acc oxidase (aco). acc synthase is encoded by a multigene that regulates the production of acc,after which this precursor is converted into ethylene by aco. pisang ambon (musa sp. aaa group),a banana cultivar originating from indonesia,has nine acs genes (maacs 1-9) and one aco gene (maaco). one of the banana acs genes,maacs2,is stress-inducible. in this research,we have investigated the expression profile of maacs2 in the roots and leaf tissues of infected tissue culture plants. quantification of gene expression was analyzed using real-time pcr (qpcr) using ma18srrna and magapdh as reference genes. the results showed nine-to ten fold higher maacs2 expression levels in the infected roots tissues compared to the uninfected roots tissues. however,maacs2 expression in the leaves was only detected in infected tissue. © 2014 published by itb journal publisher.
