Researchers Albert Cairó and Karel Riha of the Central European Institute of Technology (CEITEC) and their colleagues have discovered a previously unknown mechanism that is responsible for reprogramming gene expression in plants during the transition period when one cell differentiates into another one. The mechanism occurs at the end of meiosis, a specialized cell division essential for sexual reproduction, and enables the differentiation of germ cells and pollen. This mechanism involves the dynamic localization of key regulatory components into intracellular condensates that resemble liquid droplets. This process is closely linked to seed production and could open new possibilities for developing more sustainable crops adapted to harsher environmental conditions.
