Root hairs as a model system for studying plant cell growth by Foreman, J, Dolan, L

“…Physiological studies are identifying key transporters required for hair growth, and drug studies have been instructive in defining the role of the cytoskeleton in cell morphogenesis. Genetic analysis is identifying proteins involved in cell growth and the phenotypes of the mutants are instructive in defining the precise function of these proteins in cellular morphogenesis. …”

Evolution and function of RHO cell polarity signalling in plants by Mulvey, H

“…Collectively, the findings from this thesis reveal that an ancient signalling mechanism which became established early in the streptophyte lineage is required for the morphogenesis of complex tissues in extant land plants. …”

MpWIP regulates air pore complex development in the liverwort Marchantia polymorpha by Jones, V, Dolan, L

“…MpWIP is expressed in cells of the developing air pore complex and the morphogenesis of the complex is defective in plants with reduced MpWIP function. …”

How and where to build a root hair. by Dolan, L

“…The root hair of Arabidopsis has become a model system for investigations of the patterning and morphogenesis of cells in plants. A cascade of transcriptional regulators controls the pattern of cellular differentiation. …”

The role of reactive oxygen species in cell growth: lessons from root hairs. by Carol, R, Dolan, L

“…These studies indicate that ROS are required for cell expansion during the morphogenesis of organs such as roots and leaves. Furthermore, there is evidence that ROS are required for root hair growth where they control the activity of calcium channels required for polar growth. …”

Plant development: pulled up by the roots. by Dolan, L, Roberts, K

“…Recent advances in the study of root development in Arabidopsis have begun to yield mechanistic insights into the processes that underpin morphogenesis, pattern formation and cell differentiation in plants. …”

Local positive feedback regulation determines cell shape in root hair cells. by Takeda, S, Gapper, C, Kaya, H, Bell, E, Kuchitsu, K, Dolan, L

“…The specification and maintenance of growth sites are tightly regulated during cell morphogenesis in all organisms. ROOT HAIR DEFECTIVE 2 reduced nicotinamide adenine dinucleotide phosphate (RHD2 NADPH) oxidase-derived reactive oxygen species (ROS) stimulate a Ca2+ influx into the cytoplasm that is required for root hair growth in Arabidopsis thaliana. …”

2 WAYS TO SKIN A PLANT - THE ANALYSIS OF ROOT AND SHOOT EPIDERMAL DEVELOPMENT IN ARABIDOPSIS by Dolan, L, Roberts, K

“…Mutations affecting both the patterning and the morphogenesis of cells in both shoot and root epidermis have recently been described. …”

The COW1 locus of arabidopsis acts after RHD2, and in parallel with RHD3 and TIP1, to determine the shape, rate of elongation, and number of root hairs produced from each site of h... by Grierson, C, Roberts, K, Feldmann, K, Dolan, L

“…Two recessive mutant alleles at CAN OF WORMS1 (COW1), a new locus involved in root hair morphogenesis, have been identified in Arabidopsis thaliana L. …”

Neofunctionalisation of basic helix-loop-helix proteins occurred when embryophytes colonised the land by Bonnot, C, Hetherington, AJ, Champion, C, Breuninger, H, Kelly, S, Dolan, L

“… braunii CbbHLHVIII is expressed at sites of morphogenesis but not in rhizoids. This finding indicates that C.…”

Cellular organisation of the Arabidopsis thaliana root. by Dolan, L, Janmaat, K, Willemsen, V, Linstead, P, Poethig, S, Roberts, K, Scheres, B

“…This description of Arabidopsis root structure underpins future work on the developmental genetics of root morphogenesis.…”

Reactive oxygen species produced by NADPH oxidase regulate plant cell growth. by Foreman, J, Demidchik, V, Bothwell, J, Mylona, P, Miedema, H, Torres, M, Linstead, P, Costa, S, Brownlee, C, Jones, J, Davies, J, Dolan, L

“…Cell expansion is a central process in plant morphogenesis, and the elongation of roots and root hairs is essential for uptake of minerals and water from the soil. …”

Positional information in root epidermis is defined during embryogenesis and acts in domains with strict boundaries. by Berger, F, Haseloff, J, Schiefelbein, J, Dolan, L

“…The epidermal pattern is defined during embryogenesis and positional information remains active in the root until the initiation of cell morphogenesis. The origin of some positional cues might be extracellular.…”

The genetic control of microtubule-mediated tip-growth stability in the liverwort Marchantia polymorpha by Champion, C

“…<p>Polar growth is an important mechanism for plant cell morphogenesis. Tip-growth represents an extreme mode of polar growth where cell expansion is stably restricted to a narrow domain of the cell periphery resulting in the formation of a tubular cell projection. …”

miRNA biogenesis and developmental phase transition in the liverwort M. polymorpha by Streubel, S

“…This thesis also reports that another core regulator of miRNA biogenesis, DICER-LIKE 1 (DCL1), controls growth, morphogenesis and organ differentiation through miRNA processing in M. polymorpha, as it does in angiosperms. …”
