Genome-Wide Analysis of Gene Expression during Early Arabidopsis Flower Development [PDF]

open access: yes, 2005
Detailed information about stage-specific changes in gene expression is crucial for the understanding of the gene regulatory networks underlying development.

Structural Exploration of Zirconium Metal–Organic Frameworks Through Linker Desymmetrization and Modulator Compensation

open access: yesAdvanced Materials, EarlyView.
A linker‐desymmetrization‐modulator‐compensation (LDMC) strategy for constructing structurally diverse Zr‐MOFs is reported. This approach reduces linker symmetry to create defects in Zr‐clusters, which can be compensated for by modulator coordination. Using this approach, we synthesized PCN‐1005 and PCN‐1006, featuring unprecedented Zr‐clusters. In PCN‐

CLAVATA3 is a specific regulator of shoot and floral meristem development affecting the same processes as CLAVATA1 [PDF]

open access: yes, 1995
We have previously described the phenotype of Arabidopsis thaliana plants with mutations at the CLAVATA1 (CLV1) locus (Clark, S. E., Running, M. P. and Meyerowitz, E. M. (1993) Development 119, 397-418).

Autonomous Spatiotemporal Regulation of Reversible Hydrogel Actuators by Chemical Reaction Networks

open access: yesAdvanced Materials, EarlyView.
Hydrogel actuators with reversible response to thiols are developed using reversible binding of thiols to Michael acceptors. Autonomous spatiotemporal regulation of reversible movement of these hydrogels is achieved using thiol‐based chemical reaction networks containing both positive and negative feedback.

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

open access: yesAdvanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.

Exploring Helianthus Species for Resilience to Drought During the Critical Reproductive Stage

open access: yesPlants
Drought stress during the reproductive phase of sunflower can significantly reduce achene yield by affecting inflorescence size, nectar quality, and pollinator activity.
