dr hab. Jarosław Tyszka – okres realizacji grantu NCN 10.08.2016-9.07.2021 Factors controlling morphogenesis and biomineralization of foraminiferal shells
This project was focused on subcellular structures controlling morphogenesis and biomineralization of foraminiferal tests (shells). Observations and interpretations were based on live experiments on calcifying foraminiferal shells. Our results show that pseudopodial structures are respectively responsible for globular chamber shape and direct cellular control on biomineralization. These novel results contradict the extracellular mineralization paradigm that was proposed to explain an exceptional biomineralization pattern in calcareous foraminifera.
