As a sap-feeding insect, the BPH is *Correspondence: incapable of synthesizing several amino acids which are essential for normal growth Rui Pang and development. Therefore, the insects have to acquire these amino acids from dietary
[email protected] sources or their endosymbionts, in which amino acid transporters (AATs) play a crucial Kai Liu
[email protected] role by enabling the movement of amino acids into and out of insect cells. In this study, a common amino acid transporter gene family of amino acid/polyamine/organocation Specialty section: (APC) was identified in BPHs and analyzed. Based on a homology search and conserved This article was submitted to Invertebrate Physiology, functional domain recognition, 20 putative APC transporters were identified in the BPH a section of the journal genome.
