TL;DR: The results support the following causal sequence of events: (1) demethylesterification of pectin is triggered in subepidermal tissue layers, this contributes to an increase in elasticity of these layers-the first observable mechanical event in organ initiation, and (3) the process propagates to the epidermis during the outgrowth of the organ.

A Genomic Perspective on the Evolutionary Diversity of the Plant Cell Wall.
Ryusuke Yokoyama
- 12 Sep 2020
TL;DR: In this review, as an example of a comparative genomics approach, the diverse patterns of cell wall gene families among 100 species of green plants are examined, and the evident benefits of using genome databases for studying cell wall divergence are illustrated.
Looking beyond the gene network - metabolic and mechanical cell drivers of leaf morphogenesis.
TL;DR: This review focuses on the emerging novel mechanisms of metabolic and biomechanical regulations that coordinate plant cell growth non-cell-autonomously and reveals how metabolism and mechanics are not solely passive outcomes of genetic regulation but play instructive roles in leaf morphogenesis.
Arabidopsis β-amylase 3 affects cell wall architechure and resistance against Fusarium oxysporum
Eleni Kalogeropoulou,Despoina Beris,Sotirios E. Tjamos,Irene Vloutoglou,Epaminondas J. Paplomatas +4 more
TL;DR: This article showed that the disruption of β-amylase 3 gene (BAM3) led to increased resistance to Fusarium oxysporum f. raphani, since the Arabidopsis thaliana bam3 mutant exhibited significantly reduced susceptibility to the pathogen.
Cloning and Functional Analysis of the Pectin Methylesterase Gene GhPME6 in Upland Cotton
王琳,商海红,李俊文,王少干,刘爱英,石玉真,龚举武,巩万奎,陈婷婷 +8 more
TL;DR: Researchers cloned and functionally analyzed the pectin methylesterase gene GhPME6 in upland cotton, finding it highly conserved across cotton species and specifically expressed during secondary cell wall thickening, potentially influencing fiber strength.
Plant trichomes and the biomechanics of defense in various systems, with Solanaceae as a model
Maya Bar,Ilana Shtein +1 more
TL;DR: Plant trichomes are epidermal outgrowths of varying size and form and the chemical defensive function of the secretory trichome is well established, but the biomechanical functions of the non-glandu...

Regulation of phyllotaxis by polar auxin transport.
Didier Reinhardt,Eva-Rachele Pesce,Pia A. Stieger,Therese Mandel,Kurt Baltensperger,Malcolm J. Bennett,Jan Traas,Jiří Friml,Cris Kuhlemeier +8 more
TL;DR: It is shown that proteins involved in auxin transport regulate phyllotaxis, and data indicate that auxin is transported upwards into the meristem through the epidermis and the outermostMeristem cell layer.
Auxin Regulates the Initiation and Radial Position of Plant Lateral Organs
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.
Developmental Patterning by Mechanical Signals in Arabidopsis

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.

New insights into pectin methylesterase structure and function.
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.
