Preventing Indigenous youth homelessness in Canada: A qualitative study on structural challenges and upstream prevention in education.

Drawing on a partnership with a group of Indigenous youth experiencing homelessness in Vancouver, Canada, this study identifies four structural challenges that have impacted them and four actionable upstream strategies to further prevent youth housing precarity. As a secondary analysis of a community-engaged study with youth experiencing homelessness, we conducted a thematic analysis with qualitative data, which included qualitative interviews with five young people and researcher observations. The results reflect the racial, colonial, and economic concerns that impact Indigenous youth experiencing homelessness.

An importin-beta-like protein mediates lignin-modification-induced dwarfism in Arabidopsis.

Perturbation of lignin biosynthesis often results in severe growth and developmental defects in plants, which imposes practical limitations to genetic enhancement of lignocellulosic biomass for biofuel production. Currently, little information is known about the cellular and genetic mechanisms of this important phenomenon. Here we show that defects in both cell division and cell expansion underlie the dwarfism of an Arabidopsis lignin mutant ref8, and report the identification of a GROWTH INHIBITION RELIEVED 1 (GIR1) gene from a suppressor screen.

Social Network: JAZ Protein Interactions Expand Our Knowledge of Jasmonate Signaling.

Members of the family of JASMONATE ZIM-DOMAIN (JAZ) proteins are key regulators of the jasmonate (JA) hormonal response. The 12-member family is characterized by three conserved domains, an N-terminal domain, a TIFY-containing ZINC-FINGER EXPRESSED IN INFLORESCENCE MERISTEM domain, and a C-terminal Jas domain. JAZ proteins regulate JA-responsive gene transcription by inhibiting DNA-binding transcription factors in the absence of JA.
