    Notes: Proteinase inhibitors can be induced by wounding in shoots of tomato (Lycopersicon esculentum [L.] Mill. cv. Moneymaker). These inhibitors are toxic to insects, but their ecological importance is not clear. Published work suggests that proteinase inhibitors may be wound-inducible in tomato only while the plants are young (less than 30 days). In the present investigation the influence of plant age on wound-inducible proteinase inhibitor was re-assessed using tomato plants grown in an outdoor polythene tunnel, with natural lighting and without supplementary heat. In contrast to previous findings, proteinase inhibitor was shown to be induced by wounding in plants of all ages. However, the systemic efficacy of wounds was much reduced in mature plants, possibly because such plants have outgrown the range of the wound-signalling system.

    Salinity effects on water relations in Lycopersicon esculentum and its wild salt-tolerant relative species L. pennellii (1991)

    Notes: Cultivated tomato Lycopersicon esculentum (L.) Mill. cv. P-73 and its wild salt tolerant relative L. pennellii (Correll) D'Arcy accession PE-47, were grown during spring-summer 1989 under unheated plastic greenhouse conditions. Plants were submitted to two different salt treatments using 0 and 140 mM NaCI irrigation water. In both tomato species, salinity caused a proportionally larger reduction in leaf area than in leaf weight and, in L. esculentum, a proportionally larger decrease in stem weight than in leaf weight. Daily variations in leaf water potential (Ψ1) were fundamentally due to changes in the evaporative demand of the atmosphere. Reductions in Ψ1 due to salinity were consistent only in L. esculentum. In all the conditions studied, leaf turgor was maintained. Leaf conductance (g1)was higher in L. esculentum than in L. pennellii.Salinity induced a clear reduction in g1 levels in L. esculentum whereas, in L. pennellii, this reduction was noted only in May. In both species the Ψos (leaf osmotic potential at full turgor) levels were reduced by salinity. The bulk modulus of elasticity (E) and relative water content at turgor loss point (RWCtlp) were not affected by salinity. The RWCtlp values in L. pennellii seem to be controlled by E values.

    Water relations and osmotic adjustment in Lycopersicon esculentum and L. pennellii during short-term salt exposure and recovery (1993)

    Notes: Cultivated tomato Lycopersicon esculentum (L.) Mill. cv. P-73 and its wild salt-tolerant relative L. pennellii (Correll) D'Arcy accession PE-47 growing on silica sand in a growth chamber were exposed to 0, 70, 140 and 210 mM NaCl nutrient solutions 35 days after sowing. The saline treatments were imposed for 4 days, after which the plants were rinsed with distilled water. Salinity in L. esculentum reduced leaf area and leaf and shoot dry weights. The reductions were more pronounced when sodium chloride was removed from the root medium. Reduction in leaf area and weight in L. pennellii was only observed after the recovery period. In both genotypes salinity induced a progressive reduction in leaf water potential and leaf conductance. During the recovery period leaf water potential (ψ1) and leaf conductance (g1) reached levels similar to those of control plants in wild and cultivated species, respectively. Leaf osmotic potential at full turgor (ψos) decreased in the salt treated plants of both genotypes, whereas the bulk modulus of elasticity was not affected by salinity. Leaf water potential at turgor loss point (ψtlp) and relative water content at turgor loss point (RWCtlp) appeared to be controlled by leaf osmotic potential at full turgor (ψos) and by bulk modulus of elasticity, respectively. At lowest salinity, the wild species carried out the osmotic adjustment based almost exclusively on Cl− and Na+, with a marked energy savings. Under highest salinity, this species accommodate the stress through a higher expenditure of energy due to the contribution of organic solutes to the osmotic adjustment. The domesticated species carried out the osmotic adjustment based always on an important contribution of organic solutes.

    An Adaptive Neuro-Fuzzy Approach to Control a Distillation Column (2000)

    Notes: In this paper we use a control strategy that enhances a fuzzy controller with self-learning capability for achieving the control of a binary methanol-propanol distillation column. An Adaptive-Network-based Fuzzy Inference System (ANFIS) architecture extended to cope with multivarible systems has been used. This allows the tuning of parameters both of the membership functions and the consequents in a Sugeno-type inference system. To satisfy the control objectives the backpropagation gradient descent through the plant method is applied, hence identification of the plant dynamics is also needed. The performance of the resulting neuro-fuzzy controller under different reference settings for the concentration of methoanol demonstrates the stabilisation of the concentration profiles in the column, leading to an effective methanol composition control.

    Notes: Summary CT and MRI findings in 35 patients with the acquired immune deficiency syndrome (AIDS) and proven intracranial tuberculosis (TB) are presented. Over 90% of the patients were intravenous drug abusers and in two-thrids TB was the first manifestation of AIDS. CT was normal in one quarter, the most frequent findings being hydrocephalus (51%) and meningeal enhancement (41%), commonly seen together (31.5%). Meningeal enhancement was seen in 48% of the CT studies with intravenous contrast medium and in 3 cases studied with MRI and iv gadolinium DPTA, in 2 of which CT was negative. Parenchymal involvement was found in 37% of cases; MRI was more sensitive than CT for its detection. One quarter of the patients had ischaemic lesions, mainly in the basal ganglia. We confirm the usefulness of CT and the superiority of MRI in the diagnosis of intracranial TB and in differential diagnosis from other conditions likely to be found in these patients.

    Notes: Abstract Rapid and systemic defence responses occur in various higher plants, including the tomato (Lycopersicon esculentum L.). The long-distance signalling mechanisms which permit these responses are not clear, but three models are currently considered in the literature: phloem transport, hydraulic dispersal in the xylem, and electrical transmission. Experiments presented here are designed to discriminate between these three models on the basis of some key predictions. It is demonstrated that wound signalling can be prevented by enclosure of the shoots in polythene bags, to generate high humidity. This effect can be reversed by addition of mannitol solution to the roots, showing that it depends on saturation of the plant's water status rather than on changes in the gaseous environment of the shoot. In addition, wound signals are shown to pass freely across heat-killed tissue. These results are predicted by the hydraulic-dispersal model of signalling, but they are not compatible with the other two models. We therefore conclude in favour of hydraulic dispersal.
