Ran GTPase plays essential roles in multiple cellular processes, including nucleocytoplasmic transport, spindle formation, and postmitotic nuclear envelope (NE) reassembly. The cytoplasmic Ran GTPase activating protein RanGAP is critical to establish a functional RanGTP/RanGDP gradient across the NE and is associated with the outer surface of the NE in(More)
In higher plants, the plane of cell division is faithfully predicted by the preprophase band (PPB). The PPB, a cortical ring of microtubules and F-actin, disassembles upon nuclear-envelope breakdown. During cytokinesis, the expanding cell plate fuses with the plasma membrane at the cortical division site, the site of the former PPB. The nature of the(More)
All macromolecules that traffic between the nucleus and the cytoplasm traverse the nuclear pore. While yeast and mammalian nuclear pore structure and function have recently been substantially refined, our understanding of the plant nuclear pore is still far from comprehensive. Nevertheless, a number of nuclear pore and nucleocytoplasmic trafficking(More)
The nuclear envelope (NE) and the nuclear pores are important structures that both separate and selectively connect the nucleoplasm and the cytoplasm. NE and nuclear pore research in plants have recently seen an elevated level of interest. This is based both on new findings demonstrating the importance of nucleocytoplasmic trafficking for several signal(More)
Arabidopsis (Arabidopsis thaliana) tryptophan-proline-proline (WPP)-domain proteins, WPP1 and WPP2, are plant-unique, nuclear envelope-associated proteins of unknown function. They have sequence similarity to the nuclear envelope-targeting domain of plant RanGAP1, the GTPase activating protein of the small GTPase Ran. WPP domain-interacting tail-anchored(More)
The buckwheat metallothionein-like (MT3) gene expression was studied throughout seed and leaf development, as well as under the influence of different external stimuli. MT3 mRNAs were detected from the early stage of seed development to the end of maturation, reaching the highest level during the mid-maturation stage. High MT3 mRNA level was noticed for(More)

The leaf hairs (trichomes) on the aerial surface of many plant species play important roles in phytochemical production and herbivore protection, and have significant applications in the chemical and agricultural industries. Trichome formation in the model plant Arabidopsis thaliana also presents a tractable experimental system to study cell differentiation(More)
We have isolated and characterized a full-length cDNA for legumin-like storage polypeptide from buckwheat seed (Fagopyrum esculentum Moench) and compared its deduced amino acid sequence with those from different representatives of dicots, monocots and gymnosperms. The cDNA sequence was reconstructed from two overlapping clones isolated from a cDNA library(More)
