Centre of Plant Structural & Functional Genomics

Our research unveils the organization of genetic information of plants and explains how it controls plant growth and development. Our teams collaborate with colleagues across the world. We have participated in the ambitious projects that delivered genome sequences of important crops including barley and wheat.

New publication: Fine structure and transcription . . .
Annotation: 45S ribosomal DNA loci are organized as long head-to-tail tandem arrays of nearly identical units, spanning several megabases of sequence. Due to this structure, the rDNA loci are the major sources of gaps in genome assemblies, and expression status of particular arrays remains elusive. We combined cytogenomics techniques with bioinformatics to reconstruct individual 45S rDNA arrays in hexaploid wheat, thus building a stepping stone for . . .
New publication: Genome dominance in Allium hybrids(A. . . .
Annotation: Genome dominance is a phenomenon frequently observed in newly developed interspecific hybrids. After merging two diverse genomes in a single nucleus opens, one of the parental genomes becomes dominant, while the other turns to be submissive. In Allium hybrids (A. cepa x A. roylei), we observed that chromosomes of A. cepa are gradually substituted by those of A. roylei. Our study describes that this phenomenon is probably underlined by female . . .
New publication: Draft sequencing crested wheatgrass . . .
Annotation: Crested wheatgrass (Agropyron cristatum), a wild relative of wheat, is an attractive source of genes and alleles for their improvement. Our work has created new genomic resources and increased the knowledge about the genome/chromosome structure of A. cristatum. Chromosome draft assemblies were created, and regions homologous to agronomically important genes were identified. The classification of repetitive DNA sequences revealed the . . .

The Application Laboratory for Agricultural Research
The Application Laboratory for Agricultural Research is the first laboratory at the Czech Academy of Sciences to link scientists with breeders and farmers. It was established under the Food for Future Program of the Strategy AV21 in February 2017 and is located at the Centre of Plant Structural and Functional Genomics of the Institute of Experimental Botany in Olomouc. The main objective of the Laboratory is to facilitate the . . .
The Foods for the Future research program of Strategy . . .
The Strategy of the Czech Academy of Sciences responds to current social challenges through a sophisticated formulation of research programmes, based on cooperation of scientific fields and institutions. The research programmes of the CAS are open to partners from universities, corporations, and institutions of regional administration, as well as foreign research groups and organisations. The research programmes are proposed and formulated in discussion . . .
