Etylen a reakcje obronne roślin
Committee on Biotechnology PAS ; Institute of Bioorganic Chemistry PAS
The simplest plant growth and development hormone, ethylene, belongs (together with S.A.and JA) to key molecules governing the plant defense response. Production of ethylene is stimulated by wounding, flooding, metal ions, senescense and abscission processes, pathogeneattack and ethylene itself. High level of ethylene induces the expression of many classes ofpathogenesis-related proteins (PR). In order to properly function, ethylene must be preciselyregulated, especially at the biosynthesis and signalling pathways. Two main enzymes involvedin ethylene biosynthesis are ACC synthase and ACC oxidase. The ethylene signal transductionpathway is very complicated and needs to be further investigated. Ethylene binds to its receptorsCTRs, then the signal is transduced to CTRl and through phosforylating kinases cascades toEINs and EREBPs, directly binding to DNA GCC boxes. As a consequence, many PR proteinsare activated.
