Autor: Benoit Tesson, Alex Dajkovic, Ruth Keary, Christian Marlière, Christine C. Dupont-Gillain, Rut Carballido-López

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-14 (2022)

Abstract Cell wall homeostasis in bacteria is tightly regulated by balanced synthesis and degradation of peptidoglycan (PG), allowing cells to expand their sacculus during growth while maintaining physical integrity. In rod-shaped bacteria, actin-lik

Publikováno v: PLoS Biology, Vol 17, Iss 1, p e2005258 (2019)

Tip growth has been studied in pollen tubes, root hairs, and fungal and oomycete hyphae and is the most widely distributed unidirectional growth process on the planet. It ensures spatial colonization, nutrient predation, fertilization, and symbiosis

Characterization and localization of insoluble organic matrices associated with diatom cell walls: insight into their roles during cell wall formation.

Autor: Benoit Tesson, Mark Hildebrand

Publikováno v: PLoS ONE, Vol 8, Iss 4, p e61675 (2013)

Organic components associated with diatom cell wall silica are important for the formation, integrity, and function of the cell wall. Polysaccharides are associated with the silica, however their localization, structure, and function remain poorly un

Extensive and intimate association of the cytoskeleton with forming silica in diatoms: control over patterning on the meso- and micro-scale.

Autor: Benoit Tesson, Mark Hildebrand

Publikováno v: PLoS ONE, Vol 5, Iss 12, p e14300 (2010)

BACKGROUND: The diatom cell wall, called the frustule, is predominantly made out of silica, in many cases with highly ordered nano- and micro-scale features. Frustules are built intracellularly inside a special compartment, the silica deposition vesi

Characterization of a New Protein Family Associated With the Silica Deposition Vesicle Membrane Enables Genetic Manipulation of Diatom Silica

Autor: Mark Hildebrand, Benoit Tesson, Sarah J. L. Lerch

Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-13 (2017)
Scientific Reports

Diatoms are known for their intricate, silicified cell walls (frustules). Silica polymerization occurs in a compartment called the silica deposition vesicle (SDV) and it was proposed that the cytoskeleton influences silica patterning through the SDV

Scientific Reports, Vol 9, Iss 1, Pp 1-17 (2019)

Ectocarpus is a filamentous brown alga, which cell wall is composed mainly of alginates and fucans (80%), two non-crystalline polysaccharide classes. Alginates are linear chains of epimers of 1,4-linked uronic acids, β-D-mannuronic acid (M) and α-L

Hydrolysis of peptidoglycan is modulated by amidation of meso-diaminopimelic acid and Mg

Summary The ability of excess Mg2+ to compensate the absence of cell wall related genes in Bacillus subtilis has been known for a long time, but the mechanism has remained obscure. Here, we show that the rigidity of wild‐type cells remains unaffect

Dynamics of silica cell wall morphogenesis in the diatom Cyclotella cryptica: Substructure formation and the role of microfilaments

Autor: Mark Hildebrand, Benoit Tesson

Publikováno v: Journal of Structural Biology. 169:62-74

Diatoms are unicellular algae that make cell walls out of silica with highly ornate features on the nano- to microscale. The complexity and variety of diatom cell wall structures exceeds those possible with synthetic materials chemistry approaches. U
