A membrane receptor kinase targets a plant steroid hormone signaling complex to shape growth

Mis en avant

Plants, just like animals, contain growth promoting steroid hormones. The active hormone is sensed at the plasma membrane by a plant-unique receptor kinase. For activation, the plant steroid receptor relies on a shape-complementary helper protein. Researchers from Michael Hothorn‘s team have now uncovered that these helper proteins are targeted by other receptor kinases termed BIR proteins. The steroid receptor and BIRs compete for binding to the helper protein, thereby shaping plant growth in different cells and tissues. The study was published on May 07, 2018 in Nature Plants.

A molecular magnet controlling DNA replication

Mis en avant

The team of David Shore has shown how telomeres control the initiation of DNA replication genome-wide. The study, published on April 24, 2018 in Cell Reports, reveals that a telomere-binding protein called Rif1 is sequestered at telomeres, limiting its repressive effect on origins of DNA replication to regions near the ends of chromosomes. This may allow chromosomes ends to act as nurseries for genome evolution.
