VIP1 is a bZIP transcription factor in Arabidopsis (Arabidopsis thaliana). VIP1 transiently accumulates in the nucleus when cells are exposed to hypoosmotic conditions, but its physiological relevance is unclear. This is possibly because Arabidopsis has approximately 10 close homologs of VIP1 and they function redundantly. To examine their physiological roles, transgenic plants overexpressing a repression domain-fused form of VIP1 (VIP1-SRDXox plants), in which the gene activation mediated by VIP1 is expected to be repressed, were generated. Because hypoosmotic stress can mimic mechanical stimuli (e.g. touch), the touchinduced root-waving phenotypes and gene expression patterns in those transgenic plants were examined. VIP1-SRDXox plants exhibited more severe root waving and lower expression of putative VIP1 target genes. The expression of the VIP1-green fluorescent protein (GFP) fusion protein partially suppressed the VIP1-SRDX-induced increase in root waving when expressed in the VIP1-SRDXox plants. These results suggest that VIP1 can suppress the touch-induced root waving. The VIP1-SRDX-induced increase in root waving was also suppressed when the synthetic auxin 2,4-dichlorophenoxy acetic acid or the ethylene precursor 1-aminocyclopropane-1-carboxylic acid, which is known to activate auxin biosynthesis, was present in the growth medium. Root cap cells with the auxin marker DR5rev::GFP were more abundant in the VIP1-SRDXox background than in the wild-type background. Auxin is transported via the root cap, and the conditions of outermost root cap layers were abnormal in VIP1-SRDXox plants. These results raise the possibility that VIP1 influences structures of the root cap and thereby regulates the local auxin responses in roots.

“…This suggests mechanical manipulations may directly affect mitochondrial function. The touch-and woundingrelated microarray expression data suggest that mitochondrial dicarboxylate carriers (DICs) are among the most highly induced genes (Lee et al, 2005). Therefore, we tested if transcripts for the three Arabidopsis DIC genes are responding to the mock spray treatment presented in Figure 5B.…”

Previous studies have identified a range of transcription factors that modulate retrograde regulation of mitochondrial and chloroplast functions in Arabidopsis (Arabidopsis thaliana). However, the relative importance of these regulators and whether they act downstream of separate or overlapping signaling cascades is still unclear. Here, we demonstrate that multiple stressrelated signaling pathways, with distinct kinetic signatures, converge on overlapping gene sets involved in energy organelle function. The transcription factor ANAC017 is almost solely responsible for transcript induction of marker genes around 3 to 6 h after chemical inhibition of organelle function and is a key regulator of mitochondrial and specific types of chloroplast retrograde signaling. However, an independent and highly transient gene expression phase, initiated within 10 to 30 min after treatment, also targets energy organelle functions, and is related to touch and wounding responses. Metabolite analysis demonstrates that this early response is concurrent with rapid changes in tricarboxylic acid cycle intermediates and large changes in transcript abundance of genes encoding mitochondrial dicarboxylate carrier proteins. It was further demonstrated that transcription factors AtWRKY15 and AtWRKY40 have repressive regulatory roles in this touch-responsive gene expression. Together, our results show that several regulatory systems can independently affect energy organelle function in response to stress, providing different means to exert operational control.

Keywords: calcium signaling, mechanosensitive Ca 2+ channel, hypo-osmotic stress, reactive oxygen species (ROS), riceMechanosensing and its downstream responses are speculated to involve sensory complexes containing Ca 2+ -permeable mechanosensitive channels. On recognizing hypo-osmotic stress, plant cells initiate activation of a widespread signal transduction network involving second messengers such as Ca 2+ to trigger inducible defense responses including the induction of transcriptional factors.1 However, most of the components involved in these signaling networks still remain to be identified. Recently we identified and investigated OsMCA1, the sole homolog of the MCA family putative Ca 2+ -permeable mechanosensitive channels in rice. Functional characterization of the OsMCA1-suppressed cells as well as the overexpressing cells indicated that OsMCA1 is involved in the regulation of plasma membrane Ca 2+ influx and NADPH oxidase-mediated generation of reactive oxygen species (ROS) induced by hypo-osmotic stress. Here we will discuss possible molecular mechanisms and physiological functions of the MCA protein in hypo-osmotic signaling.
