At the end of male meiosis in the anther, plants produce 4 haploid (n) cells that are held together in a tetrad structure surrounded by a callose wall. Confocal image coloured by SR2200 stain in blue, contrasted with green autofluorescence signal. In the current issue, Schindfessel et al. analyse how heat stress interferes with normal meiotic cell cycle progression and leads to the production of diploid (2n) male gametes and polyploid offspring in the natural Arabidopsis thaliana population. They uncover a role for TARDY ASYNCHRONOUS MEIOSIS in regulating the translation of major cell cycle genes at high temperature. Image credit: Cédric Schindfessel.
