Mechanism to Control Fruit Development and Disperse in Arabidopsis and the Application For Rapeseed (Brassica napus) Breeding

Abstract: It has been reported that 20% of harvest are lost as a result of fruit development and disperse in maturity and losses up to 50% were estimated in seasons when adverse weather conditions delayed harvesting in rapeseed (Brassica napus L.). The model plant， Arabidopsis thaliana， is the same family with rapeseed and has similar fruit structure and dehiscence mechanism. An intricate process which is related with the fruit development and dehiscence had been clear in Arabidopsis thaliana. Three tissues which were valve or pod wall， replum and valve margin were associated with fruit disperse in Arabidopsis thaliana during fruit development and maturity. A series of genes had been identified to regulate three tissue's specify and development. This paper reviewed the mechanism of genes control fruit dehiscence in Arabidopsis and provided tools to engineer shatter-resistant pods to prevent seed loss in rapeseed.
