Multiplexed in situ hybridization reveals distinct lineage identities for major and minor vein initiation during maize leaf development

This study uses multiplexed in situ hybridization to show distinct lineage identities for major and minor vein initiation in maize leaves, suggesting both lineage- and position-based mechanisms in venation patterning.

THE WIP6 TRANSCRIPTION FACTOR TOO MANY LATERALS SPECIFIES VEIN TYPE IN C4 AND C3 GRASS LEAVES

This study identifies the WIP6 transcription factor TML as specifying vein rank in maize and rice, with implications for C4 photosynthesis engineering in rice.

Mutations in NAKED-ENDOSPERM IDD genes reveal functional interactions with SCARECROW and a maternal influence on leaf patterning in C4 grasses

The paper shows that mutations in NKD IDD genes worsen leaf patterning defects in C4 grasses but not C3 grasses, and identifies a maternal influence on leaf cell patterning during embryogenesis.

SCARECROW is deployed in distinct developmental contexts during rice and maize leaf development

The study shows that SCARECROW regulates stomatal development in rice and inner leaf patterning in maize, indicating divergent developmental roles after speciation.

Conditional Stomatal Closure in a Fern Shares Molecular Features with Flowering Plant Active Stomatal Responses

This study shows that active stomatal closure in the fern Ceratopteris richardii shares molecular features with flowering plant responses, suggesting conserved signaling pathways.

SCARECROW gene function is required for photosynthetic development in maize

This study shows that maize SCARECROW genes are essential for photosynthetic development, as their mutation reduces chlorophyll content and photosynthetic enzyme activity, affecting plant growth.

Optimization of a Modular Steroid-Inducible Gene Expression System for Use in Rice

The paper optimizes a steroid-inducible gene expression system for rice, showing high sensitivity but off-target effects that can be mitigated with IPTG.

Redundant SCARECROW genes pattern distinct cell layers in roots and leaves of maize

This study shows that two redundant maize SCARECROW genes regulate mesophyll and endodermal cell layer patterning in leaves and roots, respectively.
