Genome-Wide Analysis of Tubulin Gene Family in Cassava and Expression of Family Member FtsZ2-1 during Various Stress

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 sequenc...

Description
Summary: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.
