摘要: BAND7 是具有SPFH 特征结构域的一类膜蛋白,同其他膜蛋白偶联,调节离子转运和信号转导,广泛分布于不同的动物细胞中。通过序列比对,在模式植物拟南芥中鉴定到4 个可能编码BAND7 蛋白的基因,其基因代码分别是At1g69840、At3g01290、At5g62740 和At5g51570。半定量反转录PCR 检测发现,它们在拟南芥的叶和根中都有表达,叶中的表达均高于根。通过PCR 检测,获得基因At1g69840 和At5g51570 的T-DNA 插入敲除型纯合突变株SALK_088328 和SALK_104547。通过对比野生型植株和基因敲除突变体在不同培养基上的根长和鲜重方面的差异,证明植物BAND7 基因 At5g51570 参与了植物钙离子的吸收过程。

Abstract: BAND7 is one kind of proteins with SPFH structural motif and wildly distributed in various animal cells, which coupledwith other membrane proteins and regulated ion transportation and signaling transduction. By sequencing comparison, four putative BAND7genes were identified in Arabidopsis, At1g69840, At3g01290, At5g6274 and At5g51570. Semi-quantitative reverse transcript PCR analysisindicated that they expressed in both the leaf and root with comparable higher expression in the leaf. Through PCR-based detection method,T-DNA knockout homozygous mutants SALK_088328 and SALK_104547 were identified in the At1g69840 and At5g51570 genes, respectively.Comparing growth phenotype of the wild type and these mutants revealed a role of At5g51570 in the calcium homeostasis.
