摘      要：The members of myeloblastosis transcription factor(MYB TF)family are involved in the regulation of biotic and abiotic stresses in ***,the role of MYB TF in phosphorus remobilization remains largely *** the present study,we show that an R2R3 type MYB transcription factor,MYB103,is involved in phosphorus(P)***103 was remarkably induced by P deficiency in cabbage(Brassica oleracea *** L.).As cabbage lacks the proper mutant for elucidating the mechanism of MYB103 in P deficiency,another member of the crucifer family,Arabidopsis thaliana was chosen for further *** transcript of its homologue AtMYB103 was also elevated in response to P deficiency in ***,while disruption of AtMYB103(myb103)exhibited increased sensitivity to P deficiency,accompanied with decreased tissue biomass and soluble P ***,AtMYB103 was involved in the P reutilization from cell wall,as less P was released from the cell wall in myb103 than in wildtype,coinciding with the reduction of ethylene *** together,our results uncover an important role of MYB103 in the P remobilization,presumably through ethylene signaling.
