Research profile

The Team conducts research on the modelling and analysis of data from biological experiments, phylogenomic annotation of reference and
newly sequenced taxa (plants and plant-associated microorganisms), as well as generalized data processing tools and structures. Our main
scope of interest lies in the data obtained from sequencing or chromatography experiments involving secondary metabolites, biotic and abiotic stimuli. Due to high input volumes and the complementarity of analyses in biological projects, the integration of diverse data sets plays a key role in our activities. For this purpose, we employ statistical, informatic and bioinformatic methods tailored to analysis of experimental data with special focus on the fields of genetics, genomics and plant breeding programs.

Our main achievements revealed that:

  • The "minimum information" principle can be used for standardization of formatting and annotation of plant phenotypic data, as shown by the development of the Minimum Information About Plant Phenotyping Experiment (MIAPPE) recommendations (Krajewski et al., 2015; Ćwiek-Kupczyńska et al., 2016; Papoutsoglou et al., 2020; www.miappe.org; projects: TransPlant, EPPN2020)
  • A significantly depleted representation across 13 plant gene families, shows that losses of genes involved in trichome development, defense and wounding responses were strongly associated with development of stable rhizobial symbiosis in legumes (Czyż et al. 2022; NCN/SONATA grant no. 2016/21/D/NZ8/01300).
  • Semantic approach can be used to structure results of linear mixed model analyses and improve understanding of the experimental data and scientific conclusions (Ćwiek-Kupczyńska et al., 2020; projects: EPPN2020, NCN grant no. 2016/21/N/ST6/02358)
  • Xanthomonas effector XopD manipulates the expression of Arabidopsis abscisic acid signalling-related genes and activates OSCA1.1, a gene encoding a calcium-permeable channel required for stomatal closure in response to osmotic stress (You et. al., 2023).
  • A survey of 157 genomes of early-diverging fungi (Mucoromycotina) shows that a considerable representation of both terpene and nonribosomal peptide synthetase (NRPS)-like candidate secondary metabolite clusters (SMCs) exists in these (previously) underannotated taxa (Koczyk et al. 2021; NCN/OPUS grant no. 2016/21/B/NZ9/01875).
  • Genome-wide association study provided information useful in procedures of hybrid breeding of wheat (Mokrzycka et al., 2022; Tyrka et al., 2021; project HYBRE)   
  • Elevated temperature can cause genotype-specific changes in crown tissue of barley plants concerning gene expression, as studied by the high-throughput transcriptome sequencing (Mikołajczak et al., 2022; project NCN no. 2016/22/M/NZ9/00251).
