Pectin-Induced Changes in Cell Wall Mechanics Underlie Organ Initiation in Arabidopsis

TL;DR: A comprehensive overview of the pectin component homogalacturonan, including its synthesis, modification, regulation and role in the plant cell wall is given.

TL;DR: A deeper understanding of cell wall signaling will provide insights into the growth regulatory mechanisms that allow plants to survive in a changing environment.

TL;DR: How genes, phytohormones, and mechanical properties modulate leaf development are focused on, and these factors are discussed in the context of leaf initiation, polarity establishment and maintenance, leaf flattening, and intercalary growth are discussed.

TL;DR: The major cell wall polysaccharides and their implication for plant cell wall mechanics that need to be considered in order to study the growth behavior of the primary plantcell wall are reviewed.

TL;DR: The results show that auxin is required for and sufficient to induce organogenesis both in the vegetative tomato meristem and in the Arabidopsis inflorescence meristsem, and it is proposed that Auxin determines the radial position and the size of lateral organs but not the apical–basal position or the identity of the induced structures.

TL;DR: It is found that morphogenesis at the Arabidopsis shoot apex depends on the microtubule cytoskeleton, which in turn is regulated by mechanical stress, and a feedback loop encompassing tissue morphology, stress patterns, and microtubules-mediated cellular properties is sufficient to account for the coordinated patterns of micro Tubule arrays observed in epidermal cells.

TL;DR: Although, overall, protein structures are highly conserved between isoforms, recent data indicate that structural variations might be associated with the targeting and functions of specific pectin methylesterases.

TL;DR: Experimental results indicate that cell wall enlargement may be regulated at many levels.
