Abstract
Sugarcane is a C4 plant that has a unique capacity to accumulate high concentrations of sucrose in the stem. Ethylene is phytohormone that plays an important role on regulation of growth and sucrose accumulation of sugarcane. The rate limiting step of ethylene biosynthesis is mediated by the enzyme 1-aminocyclopropane-1-carboxylase synthase (ACS). In several hormone biosynthesis and signa…
