High-affinity K+ (HAK)/K+ uptake (KUP)/K+ transporters (KT) play crucial roles in the regulation of cellular K+ levels. However, little is known about these genes in the Rosaceae family. In this study, 56 putative HAK/KUP/KT genes were identified in genome sequences from Pyrus bretschneideri, Fragaria vesca, and Vitis vinifera, 21 of which were from P. bretschneideri (designated PbHAK1-21). HAK/KUP/KTs from these species, as well as from Arabidopsis and rice, were grouped into five major… Expand
