Project description:The douple mutant Arabidopsis thaliana soc1 ful, in contrast with WT, produces an interfascicular cambium and a large wood cylinder is the flowering stem. We present the RNAseq data for polyA mRNA of different developmental stages of cambium and wood formation in Arabidopsis thaliana. We sequenced 7 stages; 4 in the woody mutant soc1-6 ful-7 (herbaceous, cambium initiation, wood initiation and leaf) and 3 stages in the WT Col-0 (herbaceous, cambium and leaf). The corresponding stem anatomy is also presented in the manuscript indicating the stage of cambium development and the production of secondary xylem.

Project description:The leaf lamina joint joins the rice leaf blade and sheath, contributing significantly to the leaf angle trait. A more erect leaf facilitates the penetration of sunlight, enhancing photosynthetic efficiency and occupying less space in dense planting. Genetic screening found a mutant increased leaf angle1, ila1 from rice T-DNA insertional mutants library. We used microarrays to detail the transcriptional profile changes in the mutant ila1 lamina joint.

Project description:TIE1 regulates leaf development by repressing leaf differentiation because the semi-dominant mutant tie1-D by activation tagging displays small and hyponastic leaves and the differentiation of leaf epidermal cells is delayed in the tie1-D mutant, whereas disruption of TIE1 causes epinastic leaves with early differentiated epidermal cells. We used microarrays to investigate the molecular base underpinning the phenotypes of TIE1-overexpressing plants.

Project description:The veins of leaves are a highly evolved vascular network that allows plants to grow large and complex. The patterning process leading to their formation involves the integration of several internal and external signals, such as plant hormone auxin. Here, we show that an evolutionarily conserved transcription factor controlling leaf vein growth in flowering plants VDOF1 is dependent on autophagy for its activity in Arabidopsis thaliana leaf, suggesting that this pathway might be required for proper vascular system development in leaf. Taken together, our data forms that during leaf vein patterning there is presents a network in which a module that links VDOF1-ATG8-ANT1-SCR-SHR factors integrates Space-time dimension to provide more vein density, which establish a precondition for C4 photosynthesis transition.

Project description:Lesion mimic mutants in rice are widely known as spotted leaf (spl) mutants, of which several genotypes exhibit enhanced resistance to different races of Magnaporthe grisea. Besides naturally occurring spotted leaf mutants, tissue culture-induced reverse genetic repositories also act as sources of lesion mimic mutants in rice. We systematically evaluated a large collection of Tos17 mutant panel lines, developed and maintained at the National Institute of Agrobiological Sciences, Tsukuba, Japan, for their reaction to three different races of M. grisea and identified a lesion mimic mutant, NF4050-8, that showed lesions similar to naturally occurring spl5 mutant and enhanced resistance to all three blast races tested. Microarray analysis of ~44,000 rice genes in NF4050-8 with Nipponbare as control during the progressive lesion appearance stage revealed significant up-regulation of numerous defense/pathogenesis-related genes as well as several WRKY domain-containing genes and down-regulation of haem peroxidase gene. Subsequent real-time PCR analysis of WRKY45 and PR1b genes in NF4050-8 and spl5 suggested possible constitutive activation of a defense signaling pathway downstream of Salicylic Acid (SA) but independent of NH1 in these mutant lines of rice.

Project description:Lateral organ development is important for cucumber yield, while the molecular mechanism controlling leaf and floral organ development in cucumber remain elusive. In this report, a novel EMS-mutaginized mutant, round leaf (rl) was distinguished with remarkable round leaf shape, abnormal floral organ and inhibited tendril outgrowth in early development phase. Moreover, the ovule organogenesis disrupted completely in parthenocarpy fruit of rl. MutMap+ analysis revealed that RL encodes a protein kinase PINOID (CsPID, Csa1G537400). A non-synoymous SNP in the second exon of CsPID resulted in an amino-acid substitution from Arg in the wild type to Lys in the rl mutant. CsPID was down-regulated in rl mutant and preferentially expressed in young leaf, and flower buds. IAA quantification showed that rl plants exhibited a lower IAA content than wild type in ovary and blade edge. IAA immunolocalization results confirmed the IAA content alteration in rl plants. Transcriptome profile analysis further suggested IAA biosynthesis, polar transport and signal transduction genes participated in the leaf and floral development process by CsPID. Biochemical analyses showed that CsPID may regulate leaf shape by interacting with CsREV. In conclusion, this study revealed that the extensive genetic architecture of lateral organ organogenesis and development via CsPID regulating auxin polar transport action in cucumber.
