Mars1 kinase signaling in the chloroplast unfolded protein response (eLIFE)

In stressful situations, such as high light and nutrient scarcity, the chloroplast may experience increased proteotoxicity due to a surge in damaging reactive oxygen species. In response, a signal is sent to the nucleus to increase production of many proteins, including proteases and chaperones to help mitigate the damage. This damage control pathway has been […]

Convergent recruitment of TALE homeodomain life cycle regulators to direct sporophyte development in land plants and brown algae (eLIFE)

Life cycles in sexually reproducing plants and algae alternate between diploid (sporophytic) and haploid (gametophytic) generations. The haploid gametophyte produces gametes that mate to generate the diploid sporophyte, which in turn undergoes meiosis to generate haploid spores. Development must be coordinated with these life cycle-dependent changes in ploidy, so that mating and meiosis take place […]
