Trehalose-6-phosphate (T6P) is a signaling metabolite that regulates carbon metabolism, developmental processes, and growth in plants. In Arabidopsis (Arabidopsis thaliana), T6P signaling is, at least in part, mediated through inhibition of the SNF1-related protein kinase SnRK1. To investigate the role of T6P signaling in a heterotrophic,(More)
In a 34-year-old patient toxoplasma retinitis/ encephalitis developed 9 months after bone marrow transplantation. The BMT was complicated with a serious GVHD. Although she initially responded well to antibiotic therapy she died 2 years after BMT due to progressive infection.
Storage of potato tubers at low temperatures leads to the accumulation of glucose and fructose in a process called 'cold sweetening'. The aim of this work was to investigate the role of sucrose-phosphatase (SPP) in potato tuber carbohydrate metabolism at low temperature (4 degrees C). To this end, RNA interference (RNAi) was used to reduce SPP expression in(More)
Sucrose (Suc)-phosphate synthase (SPS) catalyses one of the rate-limiting steps in the synthesis of Suc in plants. The Arabidopsis genome contains four annotated SPS genes which can be grouped into three different families (SPSA1, SPSA2, SPSB, and SPSC). However, the functional significance of this multiplicity of SPS genes is as yet only poorly understood.(More)
