Adverse environmental conditions have negative effects on plant growth and development.
Receptor proteins on the plasma membrane sense various environmental stimuli and …

The shoot apical meristem of angiosperm plants generates leaf, stem and floral structures
throughout the plant's lifetime. To do this, the plant must maintain a population of stem cells …

Stem cells are essential for the development and organ regeneration of multicellular
organisms, so their infection by pathogenic viruses must be prevented. Accordingly …

The cells of multicellular organisms receive extracellular signals using surface receptors.
The extracellular domains (ECDs) of cell surface receptors function as interaction platforms …

The plant hormone abscisic acid (ABA) regulates stomatal movement under drought stress,
and this regulation requires hydrogen peroxide (H2O2). We isolated GUARD CELL …

Reduction/oxidation (redox) metabolism and associated signaling are key components of
cross tolerance to biotic and abiotic stresses in plants. Climate change factors such as …

Arabidopsis embryos lacking DICER-LIKE1 (DCL1), which is required for microRNA
(miRNA) biogenesis, arrest early in development. To assess the functions of embryonic …

The shoot apical meristem (SAM) is the fundamental structure that is located at the growing
tip and gives rise to all aerial parts of plant tissues and organs, such as leaves, stems and …

Formative cell divisions are critical for multicellular patterning. In the early plant embryo,
such divisions follow from orienting the division plane. A major unanswered question is how …

Embryogenesis is the beginning of plant development, yet the cell fate decisions and
patterning steps that occur during this time are reiterated during development to build the …
