* @entity3104 and @entity1507 are the prevalent @entity1568 sources for growth and development of higher plants. Here, we report on the characterization of the @entity3104 transporter (AMT) family in the perennial species @entity26340 . * In silico analysis and expression analysis of AMT genes from poplar was performed. In addition, @entity73085 ;2 and @entity73085 ;6 function was studied in detail by heterologous expression in @entity375 . * The @entity26340 genome contains 14 putative AMTs, which is more than twice the number of AMTs in @entity958 . In roots, the high-affinity @entity73085 ;2 strongly increased upon mycorrhiza formation and might be partly responsible for the high-affinity @entity3104 uptake component measured in poplar. Transcript level for the high-affinity @entity73085 ;6 was strongly affected by the diurnal cycle. AMT3;1 was exclusively expressed in senescing poplar leaves. Remarkably AMT2;1 was highly expressed in leaves while AMT2;2 was mostly expressed in petioles. Specific expression of @entity73085 ;5 in stamen and of @entity73085 ;6 in female flower indicate that they have key functions in reproductive organ development in poplar. * The present study provides basic genomic and transcriptomic information for the poplar AMT family and will pave the way for deciphering the precise role of AMTs in poplar physiology.
