- Highlighting the threat from current and near-future ozone pollution to clover in pasture.
- Hewitt DK1, Mills G2, Hayes F2, Wilkinson S3, Davies W3.Author information 1Centre for Ecology & Hydrology, Environment Centre Wales, Deinol Road, Bangor, Gwynedd LL57 2UW, UK; Lancaster University, Lancaster Environment Centre, Lancaster, Lancashire LA1 4YQ, UK. Electronic address: danhew@ceh.ac.uk.2Centre for Ecology & Hydrology, Environment Centre Wales, Deinol Road, Bangor, Gwynedd LL57 2UW, UK.3Lancaster University, Lancaster Environment Centre, Lancaster, Lancashire LA1 4YQ, UK.AbstractGlobally, the legume-rhizobia symbiosis, contained within specialised organs called root nodules, is thought to add at least 30 Tg N annually to agricultural land. The growth and functioning of a modern white clover (Trifolium repens cv. Crusader) and red clover (T. pratense cv. Merviot) cultivar were investigated in current and future ozone scenarios in solardomes. Both cultivars developed leaf injury and had significant reductions in root biomass and root nodule number in response to ozone, with Crusader also displaying a reduced size and mass of nodules. In-situ measurements of N-fixation in Crusader by acetylene reduction assay revealed reduced N-fixation rates in a future scenario with an increased background and moderate peaks of ozone. The implications for the sustainability of temperate pasture are discussed.

- A Rare Case of Solitary Fibrous Tumor of the Adrenal Gland Detected by 18F-FDG PET/CT.
- Treglia G1, Oragano L, Fadda G, Raffaelli M, Lombardi CP, Castaldi P, Rufini V.Author information 1From the *Department of Nuclear Medicine, Oncology Institute of Southern Switzerland, Bellinzona, Switzerland; †Division of Endocrine and Metabolic Surgery; ‡Institute of Pathology; and §Institute of Nuclear Medicine, Università Cattolica del Sacro Cuore, Rome, Italy.AbstractA 33-year old man underwent an F-FDG PET/CT searching for the cause of a fever of unknown origin. F-FDG PET/CT incidentally detected a focal area of markedly increased radiopharmaceutical uptake corresponding to a 2.5-cm nodule in the right adrenal gland. Laboratory data ruled out the presence of a functioning adrenal lesion. All these findings were suggestive of adrenal malignancy. After right adrenalectomy, histology showed a benign solitary fibrous tumor of the adrenal gland. This case highlights that benign solitary fibrous tumor should be considered as possible false-positive F-FDG PET/CT finding for malignancy in evaluating adrenal incidentalomas.

Electronic address: son.tran@riken.jp.AbstractThe aim of the present study was to test the hypothesis that the higher nodule amino acid content induced under certain treatments may play a role in the N-feedback regulation of nitrogenase (EC 1.18.6.1) activity by restricting the carbon supply to the functioning nodules. Growing Medicago truncatula plants under sub-optimal phosphorus conditions or upon exposure to large supply of nitrate caused significant asparagine accumulation in nodules of the treated plants. In addition, there was a remarkable decline in the nodule succinate content under phosphorus deprivation while malate was tended to increase. Interestingly, the relative share of succinate in the symbiotic tissues was totally inhibited, i.e. reached zero, by excessive nitrate application. These results provide evidence that succinate might be greatly affected by asparagine content of the nodule fraction, thereby restricting cellular carbon supply to the functioning bacteroids which leads to down-regulation of nodule metabolism and nitrogenase activity.
