Slow type anion channels (SLAC/SLAHs) play important roles during anion transport, growth and development, abiotic stress responses and hormone responses in plants. However, there is few report on SLAC/SLAHs in rapeseed (). Genome-wide identification and expression analysis of / gene family members were performed in . A total of 23 / genes were identified in . Based on the structural characteristics and phylogenetic analysis of these members, the SLAC/SLAHs could be classified into three main groups. Transcriptome data demonstrated that genes were detected in various tissues of the rapeseed and could be up-regulated by low nitrate treatment in roots. BnSLAC/SLAHs were exclusively localized on the plasma membrane in transient expression of tobacco leaves. These results will increase our understanding of the evolution and expression of the SLAC/SLAHs and provide evidence for further research of biological functions of candidates in .
缓慢阴离子通道（SLAC/SLAHs）在阴离子转运、植物生长发育、非生物胁迫响应和激素响应中发挥重要作用。然而，油菜中 SLAC/SLAHs 的报道很少（）。对油菜中的 / 基因家族成员进行了全基因组鉴定和表达分析。在油菜中鉴定到了 23 个 / 基因。根据这些成员的结构特征和系统发育分析，SLAC/SLAHs 可以分为三大类。转录组数据表明，在油菜的各种组织中检测到了 个基因，并可以在根中通过低硝酸盐处理而上调。BnSLAC/SLAHs 在烟草叶片的瞬时表达中仅定位于质膜上。这些结果将增加我们对 SLAC/SLAHs 进化和表达的理解，并为进一步研究候选基因在油菜中的生物学功能提供证据。
