A single-nuclei transcriptome census of the Arabidopsis maturing root identifies that MYB67 controls phellem cell maturation.

The periderm provides a protective barrier in many seed plant species. The development of the suberized phellem, which forms the outermost layer of this important tissue, has become a trait of interest for enhancing both plant resilience to stresses and plant-mediated CO sequestration in soils. Despite its importance, very few genes driving phellem development are known.

Exaptation of ancestral cell-identity networks enables C photosynthesis.

C photosynthesis is used by the most productive plants on the planet, and compared with the ancestral C pathway, it confers a 50% increase in efficiency. In more than 60 C lineages, CO fixation is compartmentalized between tissues, and bundle-sheath cells become photosynthetically activated. How the bundle sheath acquires this alternate identity that allows efficient photosynthesis is unclear.

A randomized controlled trial of targeted vs. General direct-to-consumer marketing to address psychotherapy attitudes and stigma in military service members and Veterans.

Many military service members and Veterans who experience a psychological need do not seek psychotherapy, which may be due to negative attitudes and stigma toward mental health services. In this study, we investigated the effectiveness of a general vs. military-specific direct-to-consumer psychotherapy marketing video to address psychotherapy attitudes in a nationwide sample of military service members and Veterans ( = 262).
