CRISPR/Cas9-mediated genome editing of MaACO1 (aminocyclopropane-1-carboxylate oxidase 1) promotes the shelf life of banana fruit.

Abstract

Banana is a fruit with high nutrient content and high economic importance. It is regarded as a main staple food in developing countries. As a typical climacteric fruit, banana will ripen and decay in one week after exogenous ethylene induction. The short shelf life of banana largely limits its storage, transportation and marketing, and causes great post-harvest loss (Krishnakumar, T. and Thirupathi, V. 2014). The shelf life of banana is closely related to ethylene production, which is the first factor considered for developing postharvest preservation technology.
