    Effect of silencing of the apoplastic invertase gene on photosynthesis in tomato

    © 2015 Pleiades Publishing, Ltd. Photosynthesis was examined in wild-type tomato plants (Lycopersicon esculentum L., cv. Money-maker) and in the transformants where gene expression of the leaf apoplastic invertase was suppressed by RNA interference (Lin8-RNAi). The influence of genetic transformation on photosynthesis depended on the demand for assimilates by sink organs. Using growth pots with low amount of soil, we found that at the initial growth stage when growth processes were particularly active, photosynthesis in Lin8-RNAi plants was higher than in the wild-type plants. As the reserves of mineral nutrients were gradually exhausted, photosynthesis decreased in both plant groups, but the decrease was more extensive in Lin8-RNAi plant form. Analysis of the distribution of 14C among the photosynthates produced after 3-min period of 14CO2 assimilation revealed the decreased incorporation of 14C into hexoses in Lin8-RNAi plants and the increased incorporation of 14C into aspartate and products of the glycolate pathway. Supplementing the soil with nitrate nitrogen as a fertilizer enhanced the non-carbohydrate trend of photosynthesis, but this trend was less pronounced in the transformed plants. Simultaneous measurements of CO2-exchange and H2O release revealed an insignificant increase in Lin8-RNAi plants of photosynthetic activity, transpiration, and intraleaf CO2 concentration. However, in 30–50 min after lowering the photon flux density from 1556 to 771 μmol/(m2 s) photosynthesis was reduced in both genotypes, whereas transpiration was diminished in wild-type plants and increased in the Lin8-RNAi form. It is concluded that the apoplastic invertase regulates photosynthesis through changes in osmolarity of the apoplastic fluid that controls the opening of stomata

    Effects of phosphate shortage on root growth and hormone content of barley depend on capacity of the roots to accumulate aba

    Although changes in root architecture in response to the environment can optimize mineral and water nutrient uptake, mechanisms regulating these changes are not well-understood. We investigated whether P deprivation effects on root development are mediated by abscisic acid (ABA) and its interactions with other hormones. The ABA-deficient barley mutant Az34 and its wild-type (WT) were grown in P-deprived and P-replete conditions, and hormones were measured in whole roots and root tips. Although P deprivation decreased growth in shoot mass similarly in both genotypes, only the WT increased primary root length and number of lateral roots. The effect was accompanied by ABA accumulation in root tips, a response not seen in Az34. Increased ABA in P-deprived WT was accompanied by decreased concentrations of cytokinin, an inhibitor of root extension. Furthermore, P-deficiency in the WT increased auxin concentration in whole root systems in association with increased root branching. In the ABA-deficient mutant, P-starvation failed to stimulate root elongation or promote branching, and there was no decline in cytokinin and no increase in auxin. The results demonstrate ABA’s ability to mediate in root growth responses to P starvation in barley, an effect linked to its effects on cytokinin and auxin concentrations

    Specific personal features of 296 children and adolescents exposed to tuberculosis and those with unidentified exposure were comparatively analyzed. Children with unidentified exposure demonstrated psychic tension, poor self-control, poorly developed social communication skills which determined disruptive interpersonal relations and uneasy personal growth. Children exposed to tuberculosis in their families were characterized by judging didactive position towards their neighbors which was formed by dysfunctional patterns of relations in their parental families. Adolescent with unidentified exposure manifested the contrast combination of pre-morbid personal attitudes which had certain etiologic contribution to the development of borderline neurotic states. The higher level of destructive reactions in the interpersonal communication was observed in the adolescents exposed to tuberculosis in their families. Identified personal features are considered to be psychological factors determining the hyperactivation of adaptive systems at the pre-morbid state and consequent development of structural functional disorders in various systems of the host, as well as providing impact on the course of tuberculosis

    © SGEM2019. In the present study, we estimated the influence of chicken manure derived biochar prepared at 400⁰C during 2 h being introduced into soil at the dose of 30 t ha-1 on the functional diversity of soil microbes. The experiment was carried out in laboratory conditions in 10L soil containers. To estimate that, substrate utilization ability of the communities were analyzed using Biolog Ecoplates® method. Biochar introduction was analyzed solo as well as with the co-influence of the following factors: Granulation, addition of 1 * 106 CFU g-1 of consortium of microorganisms (Azospirillum zeae, Bacillus megaterium, Pseudomonas fluorescens, Pseudomonas putida); addition of 0.35 l*ha-1; of a pesticide containing propiconazole 300 g*l-1 and tebuconazole 200 g*l-1; addition of 40 g*m-2 of a composite fertilizer containing 10% of nitrogen, and 26% of P2O5 and K2О each. All parameters were estimated on the 1st, 7th, 14th and 28th days of the experiment. Soil with no treatment was used as a control. It was revealed, that ʃAWCD values for all experimental samples were 1.1 – 2.1 times higher than those of control at all the four time points. The highest ʃAWCD were observed on the 1st day of the experiment for microbe amended soil as well as fertilizer and pesticide amended soil (1.7 and 2.1, correspondingly). The application of the fertilizer, the pesticide and the microbes led to the increase of fluctuation amplitudes of ʃAWCD as compared with control while the co-application of biochar smoothed those amplitudes. The application of powder and granular biochars demonstrated equal trends of influence on the functional microbial diversity
