Glycosylation of arabinogalactan-proteins essential for development in Arabidopsis
Communicative & Integrative Biology, 2016 Arabinogalactan-proteins (AGPs) are ubiquitous cell wall components present throughout the plant kingdom. They are extensively post translationally modified by conversion of proline to hydroxyproline (Hyp) and by addition of arabinogalactan (AG ...

Arabinogalactan Proteins and the Extracellular Matrix of Charophytes: A Sticky Business [PDF]
Frontiers in Plant Science, 2019 Charophytes represent the group of green algae whose ancestors invaded land and ultimately gave rise to land plants 450 million years ago. While Zygnematophyceae are believed to be the direct sister lineage to embryophytes, different members of this ...

Arabinogalactan-proteins [PDF]
WikiJournal of Science, 2021 Arabinogalactan-proteins (AGPs) are highly glycosylated proteins (glycoproteins) found in the cell walls of plants. AGPs account for only a small portion of the cell wall, usually no more than 1% of dry mass of the primary wall. AGPs are members of the hydroxyproline-rich glycoprotein (HRGP) superfamily that represent a large and diverse group of ...

The Growth Oscillator and Plant Stomata: An Open and Shut Case
Plants, 2023 Since Darwin’s “Power of Movement in Plants” the precise mechanism of oscillatory plant growth remains elusive. Hence the search continues for the hypothetical growth oscillator that regulates a huge range of growth phenomena ranging from circumnutation ...

Glycosylation Motifs That Direct Arabinogalactan Addition to Arabinogalactan-Proteins [PDF]
Plant Physiology, 2003 Abstract Hydroxyproline (Hyp)-rich glycoproteins (HRGPs) participate in all aspects of plant growth and development. HRGPs are generally highly O-glycosylated through the Hyp residues, which means carbohydrates help define the interactive molecular surface and, hence, HRGP function.

A Molecular Pinball Machine of the Plasma Membrane Regulates Plant Growth—A New Paradigm
Cells, 2021 Novel molecular pinball machines of the plasma membrane control cytosolic Ca2+ levels that regulate plant metabolism. The essential components involve: 1. an auxin-activated proton pump; 2. arabinogalactan glycoproteins (AGPs); 3. Ca2+ channels; 4. auxin-

FASCICLIN-LIKE 18 Is a New Player Regulating Root Elongation in Arabidopsis thaliana
Frontiers in Plant Science, 2021 The plasticity of root development represents a key trait that enables plants to adapt to diverse environmental cues. The pattern of cell wall deposition, alongside other parameters, affects the extent, and direction of root growth.

Structure and Development of the Legume-Rhizobial Symbiotic Interface in Infection Threads
Cells, 2021 The intracellular infection thread initiated in a root hair cell is a unique structure associated with Rhizobium-legume symbiosis. It is characterized by inverted tip growth of the plant cell wall, resulting in a tunnel that allows invasion of host cells
