Spatiotemporally distinct responses to mechanical forces shape the developing seed of Arabidopsis

This study shows that Arabidopsis seeds undergo anisotropic and isotropic growth phases driven by distinct mechanical responses in different layers of the seed coat.

Heterologous expression of a lycophyte protein enhances angiosperm seedling vigor

The paper shows that expressing a lycophyte BRX protein in Arabidopsis enhances seedling vigor by increasing seed and embryo size.

Stomatal regulators are co-opted for seta development in the astomatous liverwort Marchantia polymorpha

The paper shows that a Ia-IIIb bHLH TF module regulates seta development in liverwort Marchantia polymorpha, similar to its role in stomatal formation in stomatous plants.

A peptide-mediated, multilateral molecular dialogue for the coordination of pollen wall formation

The paper reveals a multilateral molecular dialogue involving three cell types that coordinates pollen wall formation through peptide signaling and subtilase activity.

Endosperm turgor pressure both promotes and restricts seed growth and size

The paper investigates how endosperm turgor pressure influences seed growth by both promoting expansion and restricting it through mechanical interactions with the seed coat.

ROS production by localized SCHENGEN receptor module drives lignification at subcellular precision

The paper identifies a kinase signaling relay that controls ROS production and lignification with subcellular precision by leveraging kinase localization and ROS as a co-substrate.

A two-way molecular dialogue between embryo and endosperm required for seed development

The paper identifies a bidirectional molecular dialogue between embryo and endosperm involving TWS1 and ALE1 to ensure cuticle integrity during seed development.
