Effects of retinoic acid on regenerated distro-proximal formation of Eisenia fetida

Abstract

Abstract: To prrobeinto the effects of exogenous retinoic acid (RA) on the regeneration of invertebrate,this paper measured the survival rate,biomass,and regenerated length of E.fetida segments amputated from its different position and treated with RA.The results showed that RA had little effect on the survival rate of anterior segments,but a higher effect on that of posterior segments.After treated with RA for 30 days,the regenerated length was shorter than the control.Exogenous RA disrupted and delayed the regeneration of earthworm and the formation of its head,but not the posterior regeneration.It was suggested that the regional specification during regeneration was distro-proximal,and retinoic acid played an important role in pattern formation during regeneration.

Key words: Wheat, Wet injury, Nutrition regulation
