Abstract

The PLATZ (Plant AT rich protein and zinc binding protein) transcription factor, which is a type of plant specific zinc dependent DNA binding protein, participates in regulating the process of plant growth and environmental stress responses. In order to clarify the characteristics of the family genes in birch (), the members of the family were screened and analyzed in this study. Totals of ten genes were identified in birch genome and classified into five groups base on phylogenetic relationship, genes in the same group usually possess a similar motif composition, exon or intron number. These ten genes distributed on eight chromosomes of fourteen chromosomes of birch. In addition, various -elements were distributed in the promoter regions of , especially with abundant MYC, ABRE and MYB, which were reported to be involved in salt stress responses. The RT-qPCR analysis results show that most genes have the higher expression levels in the roots compared to leaves and stems in birch. , , , and are significantly induced expressed response to salt stress. These studies provide a basis for the further functional study of the genes.

摘要

PLATZ（富含AT的植物蛋白和锌结合蛋白）转录因子是一种植物特有的锌依赖性DNA结合蛋白，参与调节植物生长过程和环境胁迫响应。为了阐明白桦中该家族基因的特征，本研究对白桦PLATZ家族成员进行了筛选和分析。在白桦基因组中总共鉴定出10个PLATZ基因，并根据系统发育关系分为五组，同一组中的基因通常具有相似的基序组成、外显子或内含子数量。这10个基因分布在白桦14条染色体中的8条染色体上。此外，各种顺式作用元件分布在PLATZ基因的启动子区域，尤其是富含参与盐胁迫响应的MYC、ABRE和MYB元件。RT-qPCR分析结果表明，在白桦中，大多数PLATZ基因在根中的表达水平高于叶和茎。BpPLATZ1、BpPLATZ3、BpPLATZ5、BpPLATZ7和BpPLATZ9对盐胁迫有显著的诱导表达响应。这些研究为进一步研究PLATZ基因的功能提供了基础。
