Lipoxygenases—Im portantEnzym es in the Ripening and Sen- scencing of Fruits and Vegetables

Sheng Jiping, Shen Lin2, and Luo Yunbo1 (College of Food, China Agricultural University, Beijing 100094;Beijing AgriculturalTechnology Extension Center)  
Lipoxygenases(LOXs) are som e kinds ofubiquitous enzym es in high plant. Studies on LOX show ed that LOXs m ay participate in the regulation of grow th, developm ent, ripening, senescence and defense reaction of plants. Recently, LOXs w ere found having close relationship w ith postharvestchanges offruits and vegetables, such as synthetic regulation ofsom e m aterials, participation in ethylene biosynthesis. Itw asalso found thatLOXs have been physiologically relat- ed to plant resistance, flavor, color and firm ness. This article briefly review ed the progress in LOXs studies on physiology ofplant, especially on the postharvestphysiology offruits, and sug- gested the w ork m ight be contacted on exploring the inhibitors of LOXs, by using various bio- chem icalm ethods such as anti-sense gene technique to regulate the biosynthesis ofthis enzym e.
