Analysis of auxin responses in the fern Ceratopteris richardii identifies tissue ontogeny as a major determinant for response properties

This study compares auxin responses in the gametophyte and sporophyte of the fern Ceratopteris richardii, finding that ontogeny, not phylogeny, determines auxin response properties.

Twilight length alters growth, flowering time, and clock function in Arabidopsis via LHY/CCA1

This study shows that twilight length affects Arabidopsis growth, flowering time, and circadian clock function through the LHY/CCA1 pathway.

Control of Leaf Vein Patterning by Regulated Plasmodesma Aperture

This study identifies three GN-dependent pathways—auxin signaling, polar auxin transport, and plasmodesma-mediated auxin movement—that collectively control vein patterning in plants.

Control of Vein-Forming, Striped Gene-Expression by Auxin Signaling

The paper investigates how striped gene expression is controlled in plants, showing that ATHB8 expression is activated in striped domains through a combination of MP activation and repression by MP target genes.

Vein Patterning by Tissue-Specific Auxin Transport

This study challenges existing hypotheses about auxin transport in vein patterning by showing that epidermal PIN1 is not required or sufficient, while inner-tissue PIN1 is both required and sufficient.

GAL4/GFP enhancer-trap lines for identification and manipulation of cells and tissues in developing Arabidopsis leaves

The paper identifies and characterizes GAL4/GFP enhancer-trap lines in Arabidopsis Columbia-0 for labeling and manipulating cells and tissues during leaf development.

A dynamic pattern of local auxin sources is required for root regeneration

This study shows that local auxin sources are essential for root regeneration after stem cell niche removal, and their activation depends on regeneration competence factors.

Coordination of tissue cell polarity by auxin transport and signaling

The paper investigates how auxin transport and signaling coordinate tissue cell polarity during vein formation, finding that GNOM acts upstream of both processes.
