An atlas of Brachypodium distachyon lateral root development

This paper creates an atlas of lateral root development in Brachypodium distachyon, showing that lateral roots originate from phloem pole pericycle cells and that auxin signaling is active in overlying cortical layers.

BZR1 promotes pluripotency acquisition and callus development through direct regulation of ARF7 and ARF19

This study shows BZR1 promotes pluripotency and callus formation by directly regulating ARF7 and ARF19 in plants.

Ectopic assembly of an auxin efflux control machinery shifts developmental trajectories

The paper shows that ectopic PAX-BRX-PIP5K module assembly reduces PIN abundance and alters root growth by accelerating xylem vessel differentiation.

Single-gene resolution of diversity-driven community overyielding

The paper identifies a gene, AtSUC8, whose allelic differences contribute to increased productivity in mixed Arabidopsis thaliana genotypes by affecting root growth sensitivity to substrate pH.

A morpho-transcriptomic map of brassinosteroid action in the Arabidopsis root

This study combines morphological and transcriptomic analyses to show brassinosteroid signaling regulates cell division orientation and anisotropic expansion in Arabidopsis roots, with non-cell-autonomous effects on root anatomy.

The transcription and export complex THO/TREX contributes to transcription termination in plants

This paper shows that the THO/TREX complex components TEX1 and HPR1 are required for proper transcription termination in Arabidopsis, leading to defects in mRNA processing and growth.

Low Rate of Somatic Mutations in a Long-Lived Oak Tree

The paper sequenced two branches of a 234-year-old oak tree and found few somatic mutations, suggesting shoot meristems are mutation-resistant.
