Abstract

Filamentous temperature-sensitive protein Z (Tubulin/FtsZ) family is a group of conserved GTP-binding (guanine nucleotide-binding) proteins, which are closely related to plant tissue development and organ formation as the major component of the cytoskeleton. According to the published genome sequence information of cassava (), 23 genes () were identified, which were divided into four main groups based on their type and phylogenetic characteristics. The same grouping generally has the same or similar motif composition and exon-intron structure. Collinear analysis showed that fragment repetition event is the main factor in amplification of cassava superfamily gene. The expression profiles of genes in various tissue were analyzed, and it was found that were mainly expressed in leaf, petiole, and stem, while was highly expressed in storage root. The qRT-PCR results of the gene under hormone and abiotic stresses showed that indole-3-acetic acid (IAA) and gibberellin A3 (GA3) stresses could significantly increase the expression of the gene, thereby revealing the potential role of in IAA and GA3 stress-induced responses.

摘要

丝状温度敏感蛋白Z(微管蛋白/FtsZ)家族是一组保守的GTP结合(鸟嘌呤核苷酸结合)蛋白,作为细胞骨架的主要成分,它们与植物组织发育和器官形成密切相关。根据已公布的木薯基因组序列信息,鉴定出23个基因,根据其类型和系统发育特征分为四个主要组。同一组通常具有相同或相似的基序组成和外显子-内含子结构。共线性分析表明,片段重复事件是木薯超家族基因扩增的主要因素。分析了该基因在各种组织中的表达谱,发现主要在叶、叶柄和茎中表达,而在贮藏根中高度表达。该基因在激素和非生物胁迫下的qRT-PCR结果表明,吲哚-3-乙酸(IAA)和赤霉素A3(GA3)胁迫可显著增加该基因的表达,从而揭示了其在IAA和GA3胁迫诱导反应中的潜在作用。
