Genome-wide identification of the SWEET gene family in <i>Phaseolus vulgaris</i> L. and their patterns of expression under abiotic stress
<p>Sugar Will Eventually be Exported Transporters (SWEET) proteins function as sugar transporters that play key roles in plant growth, development, and biotic and abiotic stress responses. However, little is known about the SWEET gene family in common bean (<i>Phaseolus vulgaris</i> L.). In this study, 24 putative <i>PvSWEET</i> genes were identified. They can be categorized into four subgroups based on a phylogenetic analysis, exon–intron structure, <i>cis</i>-regulatory elements, and MEME motifs. A collinearity analysis showed that three pairs of segmental duplicated events were identified. The Phytozome database showed that 16 <i>PvSWEET</i> genes were highly expressed in reproductive organs. <i>PvSWEET5</i> was expressed the most highly in all the tissues tested, while <i>PvSWEET8/9/10/13</i> were undetectable in the datasets. The results of qRT-PCR analysis showed that <i>PvSWEET24</i> was significantly up-regulated following treatment with NaCl, CdCl<sub>2</sub>, and HgCl<sub>2</sub>, whereas the <i>PvSWEET5</i> and <i>PvSWEET20</i> genes displayed a specific negative response to CdCl<sub>2</sub> stress. Collectively, this study provides comprehensive information for the role of <i>SWEET</i> gene family in common bean and lays a solid foundation to elucidate the biological function of the <i>PvSWEET</i> gene family, as well as provide insights into the correlation between the <i>PvSWEET</i> genes and responses to metal stresses.</p>
