Transposon-Mediated Alteration of TaMATE1B Expression in Wheat Confers Constitutive Citrate Efflux from Root Apices

Andriy Tovkach; Peter R. Ryan; Alan E. Richardson; et al. PLANT PHYSIOLOGY 2012. doi:10.1104/pp.112.207142

Other claims from this paper (10)

Observation Wheat TaMATE1B encodes a plasma-membrane citrate transporter.
Intervention effect Iron deficiency induced TaMATE1B root expression.
Intervention effect Phosphorus deficiency did not induce TaMATE1B root expression.
Intervention effect Aluminum treatment did not induce TaMATE1B root expression.
Observation Egret had a SNP approximately 2 kb upstream of the start codon.
Observation Carazinho had an 11.1-kb transposon-like element absent from Egret.
Intervention effect Carazinho promoter regions drove 20-fold greater expression in the apical rice root millimeter than Egret promoter.
Observation Fluorescence was similar in mature tissue for the two cultivars.
Intervention effect The SNP alone gave twofold greater fluorescence than the Egret promoter.
Mechanism The authors conclude that the Carazinho transposon extends TaMATE1B expression to root apices and confers citrate efflux and aluminum tolerance.
