The generation of a specific cell shape requires differential growth, whereby specific regions of the cell expand more relative to others. The Arabidopsis crooked mutant exhibits aberrant cell shapes that develop because of mis-directed expansion, especially during a rapid growth phase. GFP-aided visualization of the F-actin cytoskeleton and the behavior of(More)
ACTIN-RELATED PROTEINS 2 and 3 form the major subunits of the ARP2/3 complex, which is known as an important regulator of actin organization in diverse organisms. Here, we report that two genes, WURM and DISTORTED1, which are important for cell shape control in Arabidopsis, encode the plant ARP2 and ARP3 orthologs, respectively. Mutations in these genes(More)
A group of microtubule-associated proteins called +TIPs (plus end tracking proteins), including EB1 family proteins, label growing microtubule ends specifically in diverse organisms and are implicated in spindle dynamics, chromosome segregation, and directing microtubules toward cortical sites. Here, we report three new EB1-like proteins from Arabidopsis(More)
With the aim to enhance the plant vitamin E content, the barley gene encoding 4-hydroxyphenylpyruvate dioxygenase was overexpressed in tobacco plants under control of the 35S promoter. Transgenic lines have a higher capacity for homogentisate biosynthesis as evident by a more than 10-fold higher resistance towards the bleaching herbicide sulcotrione. Seeds(More)
In Arabidopsis, based on the randomly misshapen phenotype of leaf epidermal trichomes, eight genes have been grouped into a 'DISTORTED' class. Three of the DIS genes, WURM, DISTORTED1 and CROOKED have been cloned recently and encode the ARP2, ARP3 and ARPC5 subunits respectively, of a conserved actin modulating ARP2/3 complex. Here we identify a fourth(More)
