Plant RanGAPs are localized at the nuclear envelope in interphase and associated with microtubules in mitotic cells.
TLDR
The complementation of the yeast RanG AP mutant rna1 with Medicago sativa and Arabidopsis thaliana cDNAs encoding RanGAP-like proteins suggests a role for these proteins in the organization of the microtubular mitotic structures. Expand
Dynamic bridges--a calponin-domain kinesin from rice links actin filaments and microtubules in both cycling and non-cycling cells.
TLDR
A new KCH from rice (Oryza sativa), OsKCH1, is identified and shown to bind to micro-tubules and actin microfilaments in vitro in a domain-dependent way and this unique type of kinesin is shown to oligomerize both in vivo and in vitro. Expand
OsARF1, an auxin response factor from rice, is auxin-regulated and classifies as a primary auxin responsive gene
TLDR
OsARF1, a rice homologue of the auxin response factor (ARF) family of transcriptional regulators, is the first ARF that classifies as an early auxin-responsive gene. Expand
Life and death under salt stress: same players, different timing?
TLDR
It is proposed that the outcome of the salinity response (adaptation versus cell death) depends on the timing with which these signals appear and disappear, and that the often-neglected non-selective cation channels are relevant. Expand
Auxin Stimulates Its Own Transport by Shaping Actin Filaments1
TLDR
It is shown that by overexpression of the actin-binding protein talin, transgenic rice (Oryza sativa) lines are generated, where actin filaments are bundled to variable extent and, in consequence, display a reduced dynamics, and that this bundling of actin Filaments correlates with impaired gravitropism and reduced longitudinal transport of auxin. Expand
Is microtubule disassembly a trigger for cold acclimation?
TLDR
The appearance of cold-stable microtubules was accompanied by a reduced abundance of type TUA1/2 alpha-tubulin isotypes, which could induce freezing tolerance when a transient disassembly was artificially generated by a pulse-treatment with the antimicrotubular herbicide pronamide. Expand
Impaired Induction of the Jasmonate Pathway in the Rice Mutant hebiba1
TLDR
Hbiba represents the first rice mutant in which the induction of the jasmonate pathway is impaired providing a valuable tool to study the role of jAsmonates in Graminean development and a cross-talk between jasMonate and auxin signaling is discussed. Expand

TLDR
It is proposed that microtubules are pre-adapted for a function as mechanosensors and, in concert with the flexible actin filaments and the anisotropic cell wall, comprise a tensegral system that allows plant cells to sense geometry and to respond to fields of mechanical strains such that the load is minimized. Expand
The cytoskeleton enhances gene expression in the response to the Harpin elicitor in grapevine
TLDR
It could be shown that pharmacological manipulation of microtubules could induce gene expression in the absence of elicitor using resveratrol synthase and stilbene synthase as examples, and a role for microtubule as positive regulators of defence-induced gene expression is discussed. Expand
Identification of rice Allene Oxide Cyclase mutants and the function of jasmonate for defence against Magnaporthe oryzae.
TLDR
It is demonstrated that, in rice, jasmonate mediates the defence response against blast fungus. Expand
