Epidermal differentiation: trichomes in Arabidopsis as a model system.
Arabidopsis trichomes are an excellent model system to study all aspects of cell differentiation including cell fate determination, cell cycle regulation, cell polarity and cell expansion. Genetic analysis had initially identified mutants affecting trichome development at different developmental stages. During recent years, molecular analysis of the corresponding genes has revealed a first glim...
متن کاملCoupling membranes as energy-transmitting cables. II. Cyanobacterial trichomes
Power transmission along trichomes of filamentous cyanobacteria Phormidium uncinatum has been studied with the use of ethylrhodamine fluorescence as a probe for the transmembrane electric potential difference (delta psi). It is found that agents preventing the light-induced delta psi formation (photosynthetic redox chain inhibitor dibromothymoquinone) or dissipating delta psi (uncoupler tetrach...
متن کاملCalcium promotes cadmium elimination as vaterite grains by tobacco trichomes
In tobacco plants, elimination of Zn and Cd via the production of Ca-containing grains at the top of leaf hairs, called trichomes, is a potent detoxification mechanism. This study examines how Cd is incorporated in these biominerals, and how calcium growth supplement modifies their nature. Scanning electron microscopy coupled with energy dispersive X-ray microanalysis (SEM-EDX), microfocused X-...
متن کاملInflammasomes as microbial sensors.
Members of the Nod-like receptor family and the adaptor ASC assemble into multiprotein platforms, termed inflammasomes, to mediate the activation of caspase-1 and subsequent secretion of IL-1beta and IL-18. Recent studies have identified microbial and endogenous molecules as well as possible mechanisms involved in inflammasome activation.
متن کاملBRANCHLESS TRICHOMES links cell shape and cell cycle control in Arabidopsis trichomes.
Endoreplication, also called endoreduplication, is a modified cell cycle in which DNA is repeatedly replicated without subsequent cell division. Endoreplication is often associated with increased cell size and specialized cell shapes, but the mechanism coordinating DNA content with shape and size remains obscure. Here we identify the product of the BRANCHLESS TRICHOMES (BLT) gene, a protein of ...
