    Inclusion of TreeBioTEC Infrastructure in the Estonian Research Infrastructures Roadmap Project

    Within the framework of the Estonian Research Infrastructures Roadmap programme, the project “Plant Biology and Valorization Infrastructure” (TARISTU24-TK28, 2024–2029) received national funding under the leadership of Associate Professor Hanna Hõrak, University of Tartu. The TreeBioTEC project served as the basis for including the ERA Chair laboratory infrastructure needs in this national initiative. As a result, the TreeBioTEC team has been allocated a dedicated budget line for laboratory infrastructure support within the TARISTU24-TK28 project.

    Scientific Seminar by prof. Ykä Helariutta: “On a Two-Way Street between Arabidopsis and Tree Research”

    In February 2025, Prof. Yrjö Eero Helariutta, the ERA Chair Holder of the TreeBioTEC project, delivered a public scientific seminar at the University of Tartu. During the seminar, he presented his laboratory’s work on using Arabidopsis thaliana as a model system for understanding tree biology, focusing on vascular development. He described several key discoveries, including the role of cytokinin phytohormone signalling in controlling cambial development and callose (β-1,3-glucan) as a spacer in cell walls, which have subsequently been tested in trees. More recently, his group began applying a genetic approach in Betula trees to study branch development, identifying new concepts…

    Preparatory Kick-off Meetings Set the Stage for TreeBioTEC Project Launch

    Before the official start of the TreeBioTEC ERA Chair project on March 1, 2025, two preparatory kick-off meetings were held at the Institute of Bioengineering, University of Tartu, to ensure a smooth transition into the execution phase. These meetings took place on November 2024 and February 13, 2025, at Nooruse 1 in Tartu.The purpose of these sessions was to align institutional leadership and key stakeholders on the project’s scope, objectives, governance structure, and initial implementation plan. At the time, the ERA Chair Research Group and Project Manager had not yet been recruited, making it essential to clarify roles and responsibilities…
