Project description:SQUAMOSA promoter-binding protein-like (SPL) transcription factors play vital roles in various plant physiological processes. Although, the identification of the SPL gene family has been done in C4 grass plants, including rice and maize, the same has not been characterized in the C3 grass species Dichanthelium oligosanthes. In this study, 14 SPL genes were identified in the genome of D. oligosanthes. Gene structure analysis of the identified DoSPLs revealed the similarity and redundancy in their exon/intron organizations. Sequence comparisons within the DoSPLs and along with rice SPLs revealed the putative paralogs and orthologs in D. oligosanthes SPL genes. Phylogenetic analysis clustered the DoSPLs into eight groups along with other plant SPLs. Identification of the conserved SBP motifs in all 14 DoSPLs suggested them to be putative SPLs. In addition, the prediction of sub-cellular localization and associated functions for DoSPLs further supported to be SPL genes. The outcome of this study can serve as a framework for the isolation and functional validation of SPL genes in D. oligosanthes.

Genome wide identification and functional assignments of C<sub>2</sub>H<sub>2</sub> Zinc-finger family transcription factors in Dichanthelium oligosanthes.

Project description:Transcription factors (TFs) are biological regulators of gene function in response to various internal and external stimuli. C2H2 zinc finger proteins (C2H2-ZFPs) are a large family of TFs that play crucial roles in plant growth and development, hormone signalling and response to biotic and abiotic stresses. While C2H2-ZFPs have been well characterized in many model and crop plants, they are yet to be ascertained in the evolutionarily important C3 plant Dichanthelium oligosanthes (Heller's rosette grass). In the present study, we report 32 C2H2-ZF genes (DoZFs) belonging to three different classes-Q type, C-type and Z-type based on structural elucidation and phylogenetic analysis. Sequence comparisons revealed paralogs within the DoZFs and orthologs among with rice ZF genes. Motif assignment showed the presence of the distinctive C2H2-ZF conserved domain "QALGGH" in these proteins. Cis-element analysis indicated that majority of the predicted C2H2-ZFPs are associated with hormone signalling and abiotic stress responses. Further, their role in nucleic acid binding and transcriptional regulation was also observed using predicted functional assignment. Thus, we report an overview of the C2H2-ZF gene family in D. oligosanthes that could serve as the basis for future experimental studies on isolation and functional implication of these genes in different biological mechanism of C3 plants.
