GRIS, Genetic Resources Information System for Wheat and Triticale

The system GRIS contains the passport data for 171 000 varieties and lines (names and synonyms) – accession name, accession number, pedigree, botanical species and variety, growth habit, geographical origin, identified gene alleles, synonym, genetic status, year of registration, originator, recommended region for cultivation, years of use, maturing, market class, milling and baking quality, reaction to biotic and abiotic stressors (resistance/ tolerance/ moderate resistance/ susceptibility), sensitivity/ insensitivity to day length, gibberellic acid etc., morphological traits.

Genome-Specific Primers in Polyploid Species

The sequences among subgenomes in a polyploid species share high similarity. This makes it difficult to design genome-specific primers for sequence analysis. GSP, a web-based platform to design genome-specific primers that distinguish subgenome sequences in the polyploid wheat genome. GSP uses BLAST to extract homeologous sequences of the subgenomes in the existing databases, performs a multiple sequence alignment, and designs primers based on sequence variants in the alignment.

WheatExp : A Tool to Visualize Gene Expression in Wheat

Presented is WheatExp, an expression database and visualization tool to analyze and compare homoeologue-specific transcript profiles across a broad range of tissues from different developmental stages in polyploid wheat. Beginning with publicly-available RNA-seq datasets, a pipeline was developed to distinguish between homoeologous transcripts from each annotated gene in the hexaploid bread wheat genome. We have processed and compiled data from multiple studies into a database which can be queried either by BLAST or by searching for a known gene of interest by name or functional domain.

820K wheat Axiom genotyping data

The BBSRC funded WISP partners are pleased to announce that the 820K wheat Axiom array data set, consisting of over 380 million data points, is now available for download from the Cerealsdb web site.

The genotype dataset consist of data derived from screening a range of hexaploid lines mapping populations, nullisomic lines, Kansas deletion lines, progenitors and ancestral species against the 820K SNP array.

Mapping is in progress for the three populations included in the data set, and will be published in due course.
