ASR (ABA-stress-ripening) genes play important roles in regulating plant growth and stress responses. This study identified 29 ASR genes in wheat. 23 pairs of tandem duplication genes and six pairs of segmental duplication genes were found in wheat ASR (TaASR) gene family, respectively. It is speculated that gene duplication event is the main driving force of TaASR genes evolution. Using published RNA-seq data and the qRT-PCR results of 12 TaASR genes, we analyzed the expression profiles for TaASR genes under abiotic stresses. It found that most of the genes mainly responded to salt and low temperature stress. Finally, subcellular localization and self-activation experiments showed that the proteins encoded by 12 TaASR genes were all located in the nucleus and cell membrane, and the full-length proteins had self-activation activity, which supported their role as transcription factors. This study provides a scientific basis for a comprehensive understanding of the TaASR gene family.

A software package for the analysis of nucleotide polymorphism from aligned DNA sequence data. DnaSP can estimate several measures of DNA sequence variation within and between populations (in noncoding, synonymous or nonsynonymous sites, or in various sorts of codon positions), as well as linkage disequilibrium, recombination, gene flow and gene conversion parameters. DnaSP can also carry out several tests of neutrality: Hudson, Kreitman and Aguad (1987), Tajima (1989), McDonald and Kreitman (1991), Fu and Li (1993), and Fu (1997) tests. Additionally, DnaSP can estimate the confidence intervals of some test-statistics by the coalescent. The results of the analyses are displayed on tabular and graphic form.
View all literature mentionsA database of protein families, each represented by multiple sequence alignments and hidden Markov models (HMMs). Users can analyze protein sequences for Pfam matches, view Pfam family annotation and alignments, see groups of related families, look at the domain organization of a protein sequence, find the domains on a PDB structure, and query Pfam by keywords. There are two components to Pfam: Pfam-A and Pfam-B. Pfam-A entries are high quality, manually curated families that may automatically generate a supplement using the ADDA database. These automatically generated entries are called Pfam-B. Although of lower quality, Pfam-B families can be useful for identifying functionally conserved regions when no Pfam-A entries are found. Pfam also generates higher-level groupings of related families, known as clans (collections of Pfam-A entries which are related by similarity of sequence, structure or profile-HMM).
