Assessing the hydromechanical control of plant growth.

Multicellular organisms grow and acquire their shapes through the differential expansion and deformation of their cells. Recent research has addressed the role of cell and tissue mechanical properties in these processes. In plants, it is believed that growth rate is a function of the mechanical stress exerted on the cell wall, the thin polymeric layer surrounding cells, involving an effective viscosity.

Mechanobiology of the cell wall - insights from tip-growing plant and fungal cells.

The cell wall (CW) is a thin and rigid layer encasing the membrane of all plant and fungal cells. It ensures mechanical integrity by bearing mechanical stresses derived from large cytoplasmic turgor pressure, contacts with growing neighbors or growth within restricted spaces. The CW is made of polysaccharides and proteins, but is dynamic in nature, changing composition and geometry during growth, reproduction or infection.

Study of the genetic and phenotypic variation among wild and cultivated clary sages provides interesting avenues for breeding programs of a perfume, medicinal and aromatic plant.

A road-map of the genetic and phenotypic diversities in both crops and their wild related species can help identifying valuable genetic resources for further crop breeding. The clary sage (Salvia sclarea L.), a perfume, medicinal and aromatic plant, is used for sclareol production and ornamental purposes.

Predictors of adaptive functioning in preschool aged children with autism spectrum disorder.

Difficulties in adaptive functioning are common in autism spectrum disorder (ASD) and contribute to negative outcomes across the lifespan. Research indicates that cognitive ability is related to degree of adaptive functioning impairments, particularly in young children with ASD. However, the extent to which other factors, such as socioeconomic status (SES) and ASD symptom severity, predict impairments in adaptive functioning remains unclear.
