Transcription profiling of Arabidopsis leaf senescence

ABSTRACT: 1. Comparison of two near isogenic lines between which the genome differs only for the region of the leaf-yellowing QTL Y3-4 on chromosome III.
Experiment description:

The lines HIF404-Sha and HIF404-Bay were grown on 3 mM nitrate in growth chamber according to Loudet et al . (2002, TAG 104:1173-84) until phenotypic yellowing symptoms differed between them. Plants were collected 49 days after sowing.

2. Comparison of sugar effect on the leaf senescence progress using three RIL from the Bay-0 x shahdara population that exhibited differential leaf yellowing symptoms.
Experiment description: The recombinant inbred lines RIL310 (hypersenescing and early-senescing), RIL232 (early--senescing) et RIL045 (late-senescing) were grown in petri dishes (4,7 mM Nitrogen, with (LNG) or without (LN) glucose 2% until some difference of Fv/Fm trait can be observed (Wingler et al. 2004, New Phytol, 161 : 781-789). Growth experiments were performed in A. Wingler lab, University College of London.

The extent to which leaf senescence is induced by nitrogen deficiency or by sugar accumulation varies between natural accessions of Arabidopsis (Arabidopsis thaliana). Analysis of senescence in plants of the Bay-0 x Shahdara recombinant inbred line (RIL) population revealed a large variation in developmental senescence of the whole leaf rosette, which was in agreement with the extent to which glucose (Glc) induced senescence in the different lines. To determine the regulatory basis of genetic di ...[more]

Project description:Title : Characterization of genes differentially expressed in roots of transgenic arabidopsis lines expressing the p25 protein of beet necrotic yellow vein virus. Biological question : Rhizomania ("crazy root") is a severe disease of sugar beet caused by beet necrotic yellow vein virus (BNYVV), which is transmitted by the soil-inhabiting fungus Polymyxa betae. Symptoms of virus infection are characterized by a constricted tap root and a massive proliferation of fine rootlets that often undergo necrosis. BNYVV RNA-3 encodes a 25 kDa (p25) which is an important determinant of leaf symptom phenotype. It also governs BNYVV invasion of the plant root system and induction of rootlet proliferation in sugar beet. In order to obtain a better understanding of molecular aspects of disease development in roots and to characterize specific host genes involved in response to viral infection, transgenic Arabidopsis overexpressors of p25 viral protein was obtained and better characterized. It was shown that transgenic plants that efficiently expressed p25 protein produced more lateral roots. Comparative analysis (microarray) was performed between wild type Arabidopsis roots and transgenic Arabidopsis roots expressing p25 protein, in order to identify Arabidopsis genes differentially expressed in response to p25 viral protein. Experiment description: Seeds were surface sterilized, chilled at 4C for 4 days, and then germinated and grown on square Petri plates containing sterilized Murashige and Skoog (MS) medium with 1% sucrose. Such stock plates were arranged vertically in plastic racks and placed into growth chamber. After 5 days, plants were transferred carefully onto fresh MS medium big round plates. On each plate, 60 Wild Type (WT) plantlets were transferred on the half right of the plate, and 60 transgenic plantlets (B, E or T lines) were transferred on the half left of the plate. Plates were arranged horizontally and placed into growth chamber. Experiment 1 : 5 plates containing WT0A control plants and B0A transgenic plants. Experiment 2 : 5 plates containing WT1 control plants and B transgenic plants. 5 plates containing WT2 control plants and E transgenic plants. 5 plates containing WT3 control plants and T transgenic plants. Plants were harvested after 7 days (experiment 1) or 12 days (experiment 2), and WT roots or transgenic roots were pooled and conserved at -80C.
