Abstract

The TIFY family is a group of novel plant-specific transcription factors involved in plant development, signal transduction, and responses to stress and hormones. genes have been found and functionally characterized in a number of plant species. However, there is no information about this family in warm-season grass plants. The current study identified 24 genes in , a well-known perennial warm-season grass species with a high tolerance to aluminum toxicity and good adaptability to the barren acidic soils. All of the 24 were unevenly located on six out of nine chromosomes and could be classified into two subfamilies (ZIM/ZML and JAZ), consisting of 3 and 21 genes, respectively, with the JAZ subfamily being further divided into five subgroups (JAZ I to JAZ V). The amino acids of 24 EoTIFYs showed apparent differences between the two subfamilies based on the analysis of gene structures and conserved motifs. MCScanX analysis revealed the tandem duplication and segmental duplication of several genes occurred during genome evolution. Syntenic analyses of genes between and other five plant species (including , , , , and ) provided valuable clues for understanding the potential evolution of the EoTIFY family. qRT-PCR analysis revealed that genes exhibited different spatial expression patterns in different tissues. In addition, the expressions of genes were highly induced by MeJA and all of the EoTIFY family members except for displayed upregulated expression by MeJA. Ten genes (, , , , , , , , , and ) were observed to be highly expressed under both exogenous MeJA treatment and aluminum stress, respectively. These results suggest that genes play a role in the JA-regulated pathway of plant growth and aluminum resistance as well. The results of this study laid a foundation for further understanding the function of genes in , and provided useful information for future aluminum tolerance related breeding and gene function research in warm-season grass plants.

摘要

TIFY家族是一类新型的植物特异性转录因子，参与植物发育、信号转导以及对胁迫和激素的响应。已在多种植物物种中发现并对其基因进行了功能表征。然而，关于暖季型禾本科植物中这个家族的信息却尚无报道。本研究在[某种暖季型禾本科植物名称]中鉴定出了24个[该植物名称]TIFY基因，[某种暖季型禾本科植物名称]是一种著名的多年生暖季型禾本科植物，对铝毒具有高耐受性且对贫瘠酸性土壤具有良好适应性。这24个基因均不均匀地定位在九条染色体中的六条上，可分为两个亚家族（ZIM/ZML和JAZ），分别由3个和21个基因组成，其中JAZ亚家族又进一步分为五个亚组（JAZ I至JAZ V）。基于基因结构和保守基序分析，24个[某种暖季型禾本科植物名称]TIFYs的氨基酸在两个亚家族之间表现出明显差异。MCScanX分析表明，在[某种暖季型禾本科植物名称]基因组进化过程中发生了几个[某种暖季型禾本科植物名称]TIFY基因的串联重复和片段重复。对[某种暖季型禾本科植物名称]与其他五种植物物种（包括[其他五种植物名称]）之间的[某种暖季型禾本科植物名称]TIFY基因进行共线性分析，为了解[某种暖季型禾本科植物名称]TIFY家族的潜在进化提供了有价值的线索。qRT-PCR分析表明，[某种暖季型禾本科植物名称]TIFY基因在不同组织中表现出不同的空间表达模式。此外，[某种暖季型禾本科植物名称]TIFY基因的表达受到茉莉酸甲酯（MeJA）的强烈诱导，除了[某个基因名称]外，所有[某种暖季型禾本科植物名称]TIFY家族成员在MeJA处理下均表现出上调表达。观察到十个[某种暖季型禾本科植物名称]TIFY基因（[十个基因名称]）分别在外源MeJA处理和铝胁迫下高表达。这些结果表明，[某种暖季型禾本科植物名称]TIFY基因在植物生长的茉莉酸调节途径以及耐铝性中也发挥作用。本研究结果为进一步了解[某种暖季型禾本科植物名称]中[某种暖季型禾本科植物名称]TIFY基因的功能奠定了基础，并为未来暖季型禾本科植物耐铝相关育种和基因功能研究提供了有用信息。
