Dissecting the functions of class XI myosins in moss and Arabidopsis.
Myosin XI strides along actin tracks at rates of up to 7 mm/s, making it the fastest known processive molecular motor (Tominaga et al., 2003). Class XI myosins are unique to plants and have been implicated in plant growth, intracellular transport, and root hair elongation (Prokhnevsky et al., 2008). Arabidopsis thaliana contains 13 class XImyosins, 6 of which are expressed predominantly in male...
متن کاملTwo class XI myosins function in organelle trafficking and root hair development in Arabidopsis.
Multigene families encoding class XI myosins are conserved in higher plants, however, little information is available on specific functions of these ubiquitous molecular motors. We isolated gene knockout mutants for all 13 class XI myosins present in Arabidopsis (Arabidopsis thaliana) genome. Inactivation of 11 myosin genes resulted in no discernible phenotypes under the normal growth condition...
متن کاملClass XI myosins are required for development, cell expansion, and F-Actin organization in Arabidopsis.
The actomyosin system is conserved throughout eukaryotes. Although F-actin is essential for cell growth and plant development, roles of the associated myosins are poorly understood. Using multiple gene knockouts in Arabidopsis thaliana, we investigated functional profiles of five class XI myosins, XI-K, XI-1, XI-2, XI-B, and XI-I. Plants lacking three myosins XI showed stunted growth and delaye...
متن کاملTransposon diversity in Arabidopsis thaliana.
Recent availability of extensive genome sequence information offers new opportunities to analyze genome organization, including transposon diversity and accumulation, at a level of resolution that was previously unattainable. In this report, we used sequence similarity search and analysis protocols to perform a fine-scale analysis of a large sample ( approximately 17.2 Mb) of the Arabidopsis th...
متن کاملOverlapping functions of the four class XI myosins in Arabidopsis growth, root hair elongation, and organelle motility.
Flowering plants have evolved multigene families of the class XI myosin motors, the functions of which remain poorly understood. Here, we investigated functional profiles of the Arabidopsis myosins that belong to two paralogous pairs, XI-K/XI-1 and XI-2/XI-B, using single and double gene-knockout mutants. It was found that the myosins XI-K, XI-2, and XI-B, but not XI-1 have overlapping and addi...
