Specification of embryonic shoot stem cells via a small RNA-driven morphogenic circuit

This paper identifies a small RNA-driven morphogenic circuit in maize embryos that regulates shoot stem cell specification through auxin signaling and cell division patterning.

WUSCHEL-dependent chromatin regulation in maize inflorescence development at single-cell resolution

The paper uses single-cell ATAC-seq to show ZmWUS1 overexpression alters chromatin accessibility in maize inflorescence meristem, revealing its role in stem cell maintenance through context-dependent regulation.

Transcription factor binding site divergence across maize inbred lines drives transcriptional and phenotypic variation

The paper identifies TF binding site divergence between maize inbred lines and links it to gene expression and phenotypic variation.

Diversification and conservation of DNA binding specificities of SPL family of transcription factors

The paper analyzes DNA-binding specificities of SPL transcription factors in Arabidopsis, maize, and wheat, revealing conserved target genes and species-specific motifs linked to dimerization.

Mechanisms Of Meristem Maintenance By Maize Transcriptional Corepressors

The paper identifies REL2 and RELK1 as key regulators of maize meristem development, showing they control gene expression to maintain meristem size and influence seed yield.

Uncovering the "ZIP code" for bZIP dimers reveals novel motifs, regulatory rules and one billion years of cis-element evolution

The paper develops dDAP-seq to study bZIP heterodimer DNA binding in Arabidopsis, revealing expanded binding preferences and evolutionary origins of cis-elements.

Identifying transcription factor-DNA interactions using machine learning

The paper applies machine learning to predict transcription factor-DNA interactions in maize and soybean, achieving high accuracy in maize but high false positives in soybean.

A cis-regulatory atlas in maize at single-cell resolution

The paper creates a cis-regulatory atlas in maize using scATAC-seq, identifying cell-type-specific CREs and their regulatory roles.
