Abstract

SWEET (Sugars Will Eventually be Exported Transporter) is one of the essential protein families transporting sugar in plants. In this study, 20 genes encoding the SWEET proteins were identified from the grain aramanth (Amaranthus hypochondriacus L.) genome and analyzed. The genomic full-length of these genes ranges from 729 to 9324 nucleotides, most of which have four or five introns. The predicted proteins have 226 to 311 amino acids and possess six or seven conserved transmembrane helix regions. Most of these proteins are alkaline, with pI 8.08–9.73. Analysing the phylogeny, we can classify SWEETs of Amaranthus hypochondriacus L. (AhSWEET) into four groups: group I (three genes), group II (seven genes), group III (eight genes), and group IV (two genes). These genes are not equally distributed in the grain aramanth genome. Ten gene duplication events were detected, forming the duplicated SWEET gene pairs, including nine WD events. The duplicated gene pairs are affected by the purifying selection. which stabilizes the coding sequences of these genes. This result is a basis for further studies, such as gene function or genetic modification using SWEET genes.
