In Arabidopsis, root hair and non-hair cell fates are determined by a MYB-bHLH-WD40 transcriptional complex and are regulated by many internal and environmental cues. Brassinosteroids play important roles in regulating root hair specification by unknown mechanisms. Here, we systematically examined root hair phenotypes in brassinosteroid-related mutants, and(More)
The authors demonstrate that different NMDAR antagonists (ketamine and MK-801) have varying effects on spine density depending on dose, drug regimen, and brain region. While acute ketamine treatment increases cortical spine density in mice, subchronic exposure to either drug reduces spine density in both the cortex and striatum.
