Abstract
Plant AT-rich sequence and zinc-binding protein (PLATZ) is a plant transcription factor that has been studied in
corn.
PLATZ can non-specifically bind to sequences rich in A/T bases to induce transcriptional repression. It is
involved in the regulation of dehydration tolerance in seeds. In this study, we performed bioinformatics analysis
to identify and characterize wheat
PLATZ(
TaPLATZ)genes. We identified 49 wheat
PLATZ genes by searching the
wheat genome by using known
PLATZ gene sequences from rice,
Arabidopsis, and maize. Phylogenetic analysis
on
PLATZ gene sequences from different species was performed. We found that
PLATZs could be divided into
three groups. The chromosome (chr) distribution analysis revealed that the 49 identified wheat
PLATZ genes
are distributed in 15 chrs. Gene structure and motif analyses indicated that most
PLATZ genes possess conserved
exon/intron arrangements and motif compositions. Our analysis of transcriptional data indicated that several
wheat
PLATZ genes may play an important role in abiotic stress resistance given that they are expressed under
salt stress. The results of qRT-PCR further confirmed that
TaPLATZ is involved in plant abiotic stress and is also
related to the cell differentiation of plant tissues. Our results lay the foundation for further studies on the function
of the wheat
PLATZ gene family.
