It is with immense pride that I congratulate my brilliant former PhD students, Dr. Magdalena Zaranek and Dr. Renee Perez-Perez, on their outstanding achievements.

Not only have they both successfully defended their doctoral theses, but they have also been honored with the prestigious Prof. Stefan Barbacki Award from the Institute of Plant Genetics, Polish Academy of Sciences.

We are all incredibly proud of you, Doctors! The future of science is bright with researchers like you.

🌱 Nowe badania naszej grupy na pokazują, że anatomia szparek to nie wszystko!

Porównaliśmy 3 gatunki:
🔹 B. distachyon (2n)
🔹 B. stacei (2n)
🔹 B. hybridum (4n)

Tetraploid miał większe, rzadsze szparki, ale podobną wydajność gazową jak B. distachyon.

Zaskoczenie: B. stacei miał TAKĄ SAMĄ anatomię szparek jak B. distachyon, ale O WIELE GORSZĄ wymianę gazową! 😮

Klucz? W komórkach pomocniczych B. stacei brakowało pektyny (arabinanu), co mogło utrudnić otwieranie szparek.

Stomata, the epidermal pores enabling gas exchange and transpiration, are crucial for plant fitness and global water and carbon cycling. Grasses possess efficient four-celled, graminoid stomatal complexes, where dumbbell-shaped guard cells (GCs) and lateral subsidiary cells (SCs) enable rapid stomat...

New paper on Buckwheat is here!!! 🌾

Our new study, published in PCTOC, reveals how three different buckwheat species have unique metabolic strategies in in vitro tissue culture 🧪🌱

We compared callus cultures of common buckwheat (F. esculentum), Tartary buckwheat (F. tataricum), and their wild relative (F. homotropicum), focusing on their phenolic compound profiles. The results show a remarkable divergence in phenolic metabolism between the species!

We invite you to take a look at it: https://doi.org/10.1007/s11240-025-03178-0

The genus Fagopyrum includes economically important species such as F. esculentum and F. tataricum, which are valued for their nutritional and bioactive properties, as well as their wild relative F. homotropicum, which is understudied in tissue culture systems. While callus cultures of Fagopyrum spe...

Our latest paper on Buckwheath is out! 🎉

"Effect of potent inhibitors of phenylalanine ammonia-lyase and PVP on in vitro morphogenesis of Fagopyrum tataricum".

This study demonstrates how phenylalanine ammonia-lyase (PAL) inhibitors and phenolic adsorbents can significantly improve Fagopyrum tataricum morphogenesis in vitro. By counteracting oxidative browning—a major challenge caused by the plant's high phenolic content—we achieved remarkable regeneration outcomes.

https://doi.org/10.1186/s12870-025-06440-x

Background Fagopyrum tataricum (Tartary buckwheat) is known for its high phenolic content, particularly rutin. High concentrations of these compounds secreted in the tissue culture medium can lead to its darkening and the eventual death of explants in in vitro cultures. This study aims to enhance th...

We are pleased to present our Group's latest research, titled “Evolutionary history written in tandem arrays – satellite repeats in the Lagoseris lineage of Crepis sensu lato (Asteraceae)”.This report described the comparative analyses of the genomic and chromosomal organization of tandem repetitive sequences isolated from Crepis palaestina in genomes of five closely related species from the Lagoseris evolutionary lineage. Our data suggested that extensive changes in the chromosomal organization of tandem repetitive sequences accompanied the evolution of this lineage.

Abstract. Satellite DNA families are excellent markers in evolutionary studies of plant karyotypes. Together with phylogenetic background, they can provide

We are pleased to present our Group's latest research, titled “ Does time matter? Intraspecific diversity of ribosomal RNA genes in lineages of the allopolyploid model grass Brachypodium hybridum with different evolutionary ages”. This comprehensive study draws a complex picture of rRNA gene evolutionary trajectories in two B. hybridum lineages of distinct evolutionary ages and cross directions. Our publication addresses the following questions: i) are the evolutionary trajectories of 35S and 5S rDNA homoeologues similar?; (ii) is there a relationship between the direction of the cross and rDNA homoeologues loss in B. hybridum?; (iii) do the rRNA genes in the studied B. hybridum lineages of different evolutionary ages follow the same evolutionary pathways?

Background Polyploidisation often results in genome rearrangements that may involve changes in both the single-copy sequences and the repetitive genome fraction. In this study, we performed a comprehensive comparative analysis of repetitive DNA, with a particular focus on ribosomal DNA (rDNA), in Br...

We are delighted to share a comprehensive study of cell colony development derived from protoplast cultures of Fagopyrum tataricum and F. esculentum. Combining analysis of proteomes, cell wall composition and changes in the expression profiles of selected genes revealed accumulation of embryogenesis-related proteins and dynamic distribution of cell wall components. We suppose that these changes seems to be connected with regaining somatic cells’ totipotency and promoting embryogenic competence of protoplast-derived cell colonies. This work offers valuable and new insights into cell colony development!

Background Due to the totipotency of plant cells, which allows them to reprogram from a differentiated to a dedifferentiated state, plants exhibit a remarkable regenerative capacity, including under in vitro culture conditions. When exposed to plant hormones, primarily auxins and cytokinins, explant...

We are pleased to present our Group's latest research, titled “H3K4me3 modifications in cell wall genes during the development of morphogenic and non-morphogenic calli in Fagopyrum tataricum.” This comprehensive study unravels the role of histone methylation in the development of F. tataricum callus tissue under in vitro conditions. Using chromatin immunoprecipitation (ChIP) sequencing, we mapped the distribution of this epigenetic mark across the genome in calli with differing morphogenic potential. Additionally, we implemented native chromatin immunoprecipitation, the first such protocol applied to Fagopyrum species, to assess H3K4me3 levels in genes related to cell wall development. Our research is further enriched by gene expression analysis and immunohistochemical localization of pectin and extensin epitopes. This work offers valuable new insights into the epigenetic regulation of plant tissue development!

We are delighted to share an extensive analysis of the DNA methylation patterns in floral parts of F. esculentum and F. tataricum. Our analysis revealed a fluctuation in DNA methylation levels across floral parts between species in various stages of development.

Background Proper flower development is essential for plant reproduction, a crucial aspect of the plant life cycle. This process involves precisely coordinating transcription factors, enzymes, and epigenetic modifications. DNA methylation, a ubiquitous and heritable epigenetic mechanism, is pivotal....
