Project description:Purpose: The root hair is a model for understanding evolution of individual cell differentiation programs in plants. We compare the expression of the genes that participate in root hair development between Arabidopsis and other vascular plants to assess the conservation/diversification of the root hair development programs in vascular plants. Methods: We used RNA-Seq, in triplicates, to measure the genome-wide transcription activity of the root-hair cells isolated by Fluorescence-activated cell sorting (FACS) in Arabidopsis (COBL9::GFP transgeneic line, AtRH) and rice (EXPA30::GFP transgenic line, OsRH). We also generated RNA-Seq data, in triplicates, on the Arabidopsis rhd6 WER::GFP and WT WER::GFP by FACS to identify the RHD6-regulating root hair morphogenesis genes (AtRHM). For Arabidopsis, rice, tomato, soybean, cucumber and maize, we used RNA-seq, in triplicates, to measure genome-wide transcription activity of root hair cells filtered by sieves after stirred in liquid nitrogen (HAIR genes). Each sample was trimmed to retain high-quality reads, mapped to the reference genome by TopHat, and quantified by Cufflinks. The number of raw reads of Arabidopsis rhd6 WER::GFP and WT WER::GFP sample was counted by HTSeq and analyzed by edgeR to identify the differentially expressed genes. Results: We defined the root-hair transcriptome in diverse vascular plant species and analyzed the relative conservation/divergence in the expression of a large set of gene families.

Project description:Vascular plant diseases, such as rice bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) and crucifer black rot caused by Xanthomonas campestris pv. campestris (Xcc), cause huge yield loss of crops worldwide. However, how plants operate vascular defense against these obligate pathogens remains elusive. In this study, we used both Arabidopsis and rice pathosystems to address the long-standing question. We found that the loss of function mutation of Arabidopsis mitogen-activated protein kinase (MAPK) phosphatase 1 (MKP1) lost the non-host resistance to Xoo and supported Xoo to grow in the leaf veins, which also enhanced susceptibility to Xcc. MKP1 regulates the MPK3-mediated phosphorylation of the transcription factor MYB4 that functions in vascular lignification. Importantly, the MKP-MAPK cascade-mediated lignin biosynthesis is also conserved in rice through regulating OsMYB102 and OsMYB108, which control rice vascular resistance to adapted Xoo. Interestingly, the Arabidopsis and rice mutants enhanced resistance to the mesophyll cell pathogens most likely through upregulating salicylic acid biosynthesis, Pseudomonas syringae (P. syringae) and Xanthomonas oryzae pv. oryzicole (Xoc), respectively; strongly suggesting that this immune mechanism is likely specific to the obligate vascular pathogens. Therefore, our study uncovers a previously unrecognized vascular-specific and lignin-based immune mechanism, shedingshedding new sight on tissue-specific immunity in plants, as well as providing a practical approach for improvement of disease resistance against vascular pathogens in crops

Project description:We report the application of small RNA sequencing for high-throughput profiling of small RNA under 75 bp in vascular smooth muscle cell. By a reading depth of 30M and single stranded sequencing, we generated the small RNA signature on differentiated and de-differentiated vascular smooth muscle cell induced by PDGF-BB and H3K4me2 editing. We found that PDGF-BB and H3K4me2 editing induced de-differentiation modulated miRNA profile significantly, which was demonstrated at least in part responsible for modulated vascular smooth muscle cell phenotype.

Project description:Arabidopsis thaliana polyamine oxidase 5 gene (AtPAO5) functions as a thermospermine (T-Spm) oxidase. Aerial growth of its knock-out mutant (Atpao5-2) is significantly repressed by low dose(s) of T-Spm but not by other polyamines. Massive analysis of 3â-cDNA ends (MACE) was performed. Cell wall, lipid and secondary metabolisms were dramatically affected in low dose T-Spm-treated Atpao5-2. Intriguingly Fe-deficient responsive genes and drought stress-induced genes were up-regulated, suggesting that vascular system loses the function. Histological observation showed that vascular system of the joint part between stem and leaves was structurally destroyed. The results indicate that T-Spm homeostasis by a balance of synthesis and catabolism, catalysed by AtPAO5 in Arabidopsis, is important for maintaining vascular system. Phylogenetic analysis showed that PAOs from vascular plants are classified into four clades (I-IV) and AtPAO5 belongs to the clade III. Clade III members show high identity to metazoan PAOs and are not found in non-vascular plants. Furthermore, all the clade III genes are intron-less or contain a single intron whereas the other three clade genes usually contain 7 to 9 introns. The data suggest the occurrence of a horizontal gene transfer of ancestral clade III PAO gene(s) from primitive animals. Fine tuning of T-Spm metabolism is critical for vascular plants and its catabolic gene was acquired from a certain Metazoan to equip the vascular system. 8 Samples analyzed by MACE (Massive Analysis of cDNA ends)

Project description:Analyses of the age-related changes that occur at a gene expression level and transcriptional profile have not been elucidated in depth. To determine the changes of the vascular transcriptome, we conducted gene expression microarray experiments on aortas of adult and old mice, in which age-related vascular dysfunction was confirmed by increased stiffness and associated systolic hypertension

Project description:We used N-(1-naphthyl) phthalamic acid (NPA)-induced vascular overgrowth in Arabidopsis leaves to look for differential up-regulation of genes in NPA-treated tissues that may be involved in vascular differentiation. Arabidopsis thaliana Col-0 plants were grown for approximately 2 weeks on solid ATS medium (1) containing a final concentration of 10 um NPA (dissolved in DMSO) or an equivalent volume of DMSO (control). At this stage plants had approximately 6 rosette leaves. RNA was prepared from entire shoot tissues of control (DMSO) or NPA-treated plants.(1) Lincoln et al., 1990. Plant Cell 2: 1071-1080.
