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:Verticillium longisporum is a soil-borne fungal pathogen causing vascular disease predominantly in oilseed rape. The pathogen enters its host through the roots and entertains a parasitic life stage in the xylem before invading other tissues late in the infection cycle. We have started to approach the question how and when the host plant senses the colonization of the xylem using Arabidopsis thaliana as a model plant. Although the stress-related phytohormones salicylic acid, jasmonic acid and abscisic acid increase only at 28 to 35 days, expression of V. longisporum-induced genes (VliGs) starts in the leaf veins as early as 5 dpi when disease symptoms and fungal DNA cannot yet be detected. It is concluded that an elicitor is transported from the root to the aerial parts. More than one third of the VliGs identified by whole genome expression profiling at 18 dpi encode apoplastically localized proteins involved in cell wall modifications and potential defense responses. The identified VliGs provide a useful tool to elucidate the contribution of the induced genes to the disease phenotype and the defense response. Moreover, they will help to identify the elicitor(s) and the components of the signal transduction chain that shape the V. longisporum – plant interaction.

Project description:Japonica rice (Oryza sativa ssp. japonica) variety Mudanjiang 8 (MDJ8) is the wild-type and is susceptible to Xoo. Transgenic rice line Rb49 carries the MR gene Xa3/Xa26, which is driven by its native promoter with the genetic background of MDJ8, and this line is resistant to certain strains (including strain PXO61) of Xoo. Although many studies on Xa3/Xa26-mediated resistace to rice Xoo have been published, the molecular mechanism of this major resistance gene remains poorly understood. Here, we use affymetrix microarray technology to analyze the regulated network mediated by Xa3/Xa26 We used microarrays to study the gene expression network mediated by Xa3/Xa26. Plants were inoculated with the Xoo strain PXO61 at the four-leaf to five-leaf stage by the leaf-clipping method. Control rice plants were inoculated with water (mock inoculation). Samples were collected before inoculation (ck) and at 2, 4, and 24 hours after PXO61 or mock inoculation from Rb49 and MDJ8. Leaf fragments approximately 2 cm in length that were immediately next to the inoculation site were collected.
