In order to model brittle fracture, we have implemented a two and three dimensional phase-field
method in the commercial finite element code Abaqus/Standard. The method is based …

Superoxide and its derivatives are increasingly implicated in the regulation of physiological
functions from oxygen sensing and blood pressure regulation to lymphocyte activation and …

Spontaneously arising channels that transport the phytohormone auxin provide positional
cues for self-organizing aspects of plant development such as flexible vasculature …

NADPH oxidase 5 (NOX5) is a homologue of the gp91 phox subunit of the phagocyte NADPH
oxidase. NOX5 is expressed in lymphoid organs and testis and distinguished from the …

Cytochrome P450 enzymes of the closely related CYP90 and CYP85 families catalyze
essential oxidative reactions in the biosynthesis of brassinosteroid (BR) hormones. Arabidopsis …

The role of prenylation in the interaction of Rho-family small GTPases with their GTPase
activating proteins (GAPs) was investigated. Prenylated and nonprenylated small GTPases …

To identify genetic factors contributing to psoriasis susceptibility, gene expression profiles of
uninvolved epidermis from psoriatic patients and epidermis from healthy individuals were …

The Arabidopsis CPD gene encodes a cytochrome P450 steroid side‐chain hydroxylase (CYP90)
that plays an essential role in the biosynthesis of the plant hormone brassinolide. …

Brittle and ductile dynamic fracture in solids is a complex mechanical phenomenon which
attracted much attention from both engineers and scientists due to its technological interests. …

Plants, like other multicellular organisms, survive through a delicate balance between growth
and defense against pathogens. Salicylic acid (SA) is a major defense signal in plants, and …
