  2. Identification of the pheophytin-Q(A)-Fe domain of the reducing side of the photosystem II as the Cu(II)-inhibitory binding site

    Yruela Guerrero, Inmaculada; Montoya Blanco, Guillermo; Alonso, Pablo J.
    Oxygen evolution by photosystem II membranes was inhibited by Cu(II) when 2,6-dichlorobenzoquinone or ferricyanide, but not silicomolybdate, was used as electron acceptor. This indicated that Cu(II) affected the reducing side of the photosystem II. The inhibition curves of Cu(II), o-phenanthroline and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU), were compared; the inhibitory patterns of Cu(II) and o-phenanthroline were very similar and different in turn from that of DCMU. Cu(II) did not eliminate or modify the electron paramagnetic resonance signal at g = 8.1 ascribed to the non-heme iron of the photosystem II reaction center, indicating that the inhibition by Cu(II) was not the result of...

  7. In search of molecular markers for androgenesis

    Pulido Bosch, Antonio; Castillo Alonso, Ana María; Vallés Brau, María Pilar; Olmedilla, Adela
    We have used specific antibodies against callose, pectins and arabinogalactan-proteins, all components of the cell wall involved in embryo development, to study their distribution during androgenesis induced in barley anthers in the hope that they might serve as markers of this process. Callose was found in the outer region of the intine in induced embryos and in the numerous plasmodesmata within these embryos. Anti-callose antibodies proved useful for following the evolution of these structures throughout the formation of the pollen embryo. The monoclonal antibodies JIM5 and JIM7, which recognise unesterified and methylesterified pectins respectively, were used to follow the evolution...

  8. Plant density affects yield, yield components, and color of direct-seeded paprika pepper

    Cavero Campo, José; Gil Ortega, Ramiro; Gutiérrez López, Miguel
    Paprika pepper (Capsicum annuum var. annuum L., 'Agridulce SIA') was direct-seeded on raised beds in double rows 0.35 cm apart. Plants were thinned within the row to establish densities ranging from 13,333 to >500,000 plants/ha. Yield of paprika pepper increased as plant density increased, but plant densities >200,000 plants/ha resulted in only small increases in yield. Fruit number and dry fruit weight/plant decreased with increasing plant populations, and weight/fruit decreased slightly. The increase in yield/ha as plant density increased was a result of increased numbers of fruits/ha. Pigment content (ASTA units) declined linearly as plant density increased, whereas moisture content...

  9. On the reorganisation of the LH2 850 nm band of Ectothiorhodospira sp. after acidic/chaotropic treatment

    Buche, André
    Acidic/chaotropic conditions induce a 14 nm reversible blueshift of the 850 nm band of the Ectothiorhodospira sp. antenna complex two (LH2), from 856 to 842 nm. This shift occurs with concomitant but practically irreversible blue shift, strong intensity amplification and inversion of corresponding CD signal. Assuming that B850 arises from two transitions we simulated CD spectra corresponding to LH2 samples in acidic/chaotropic buffer conditions and after reversion to pH 8/standard conditions of buffer. The poor correlation between the absorption shifts and corresponding CD of B850 could be explained by a change in the position of the wavelength maximum of both...

  11. Effects of two iron sources on iron and cadmium allocation in poplar (Populus alba) plants exposed to cadmium

    Fodor, Ferenc; Gáspár, László; Morales Iribas, Fermín; Gogorcena Aoiz, Yolanda; Lucena, Juan J.; Cseh, Edit; Kröpfl, Krisztina; Abadía Bayona, Javier; Sárvári, Éva
    Effects of 10 μM cadmium (supplied as Cd nitrate) on the utilization and allocation of iron (Fe) were investigated in poplar (Populus alba L.) plants grown in nutrient solution with Fe(III)-EDTA or Fe(III)-citrate as the Fe source. The effects of Cd were also compared with those of Fe deprivation. The accumulation of Fe in roots was 10-fold higher in plants grown with Fe-citrate than with Fe-EDTA. Cadmium decreased leaf chlorophyll concentrations and photosynthetic rates, and these decreases were more marked in plants grown with Fe-citrate than with Fe-EDTA. In both Fe treatments, addition of Cd caused large increases in root...

  13. Tolerance response to iron chlorosis of Prunus selections as rootstocks

    Jiménez Tarodo, Sergio; Pinochet, Jorge; Abadía Bayona, Anunciación; Moreno Sánchez, María Ángeles; Gogorcena Aoiz, Yolanda
    The use of rootstocks tolerant to iron deficiency represents the best alternative to prevent Fe chlorosis for peach production in calcareous soils. Early detection laboratory screening procedures allow the selection of new Fe-efficient rootstock genotypes. Seventeen Prunus rootstocks were tested for root ferric chelate reductase (FC-R) enzymatic activity, leaf SPAD values, and field performance. Some rootstocks were used as a reference to compare with new Prunus selections. Micropropagated plants were grown in hydroponic culture with half-strength Hoagland's nutrient solution containing 90 μM Fe(III)-EDTA as a control treatment. Plants were transferred to iron-free fresh solutions for 4 days and were thereafter...

  16. Pollen development and chilling requirements in apricot cultivars

    Julián Lagunas, Carmen; Herrero Romero, María; Rodrigo García, Javier
    Apricot (Prunus armeniaca L.) flowers at the end of the winter but flower bud differentiation occurs the previous summer. During the winter, the flower bud enters dormancy and resumes growth prior to flowering. The time the flower bud remains dormant is genetically and also environmentally controlled and is a major factor in determining the adaptation of particular cultivars to particular ecological conditions. In apricot, as in other temperate fruit species, chilling is required for buds to emerge from rest, and chilling requirements vary greatly among cultivars. However, very little is known on the physiological changes underlying these events. To explore...

  17. Pollen tube behavior in different Mandarin hybrids

    Distefano, Gaetano; Las Casas, Giuseppina; La Malfa, Stefano; Gentile, Alessandra; Tribulato, Eugenio; Herrero Romero, María
    Seedlessness is an important trait in the evaluation of commercial mandarin for fresh consumption. However, in the last decade, the presence of seeds in fruit of cultivars considered as seedless has become a problem in different citrus-growing areas because the commercial value is depreciated. Seeds have appeared concomitantly with the introduction of new cultivars that appear to be cross-compatible. To overcome this problem, different strategies have been explored, but a definitive answer is still elusive. The search for alternatives contrasts with how little is known about the basis of the problem: the pollen-pistil incompatibility reaction in mandarin, and the intercompatibility...

  18. Variabilidad espacial del transporte de sedimento en la cuenca superior del río Aragón

    Navas Izquierdo, Ana; Navas Izquierdo, Ana; Valero-Garcés, Blas L.; Gaspar Ferrer, Leticia; García-Ruiz, José María; Beguería, Santiago; Machín Gayarre, Javier; López-Vicente, Manuel
    [ES] En el siglo pasado se produjo una importante regulación de los recursos hídricos en España con la construcción de numerosos embalses. En 1959, el río Aragón fue represado en Yesa (Depresión Interior del Pirineo Central) y desde entonces los sedimentos se han ido acumulando en su vaso, reduciendo así su capacidad inicial de almacenamiento de agua. En este trabajo se analiza el transporte de sedimentos en la red hidrológica del río Aragón desde la cabecera hasta el embalse de Yesa. Para ello se ha realizado el muestreo de aguas superficiales en 44 puntos distribuidos en las principales subcuencas del...

  19. A novel approach to study the regulation of cell proliferation

    De la Torre, Consuelo; Giménez-Abián, M. I.; Giménez-Martín, G.
    [EN] In this paper we explain how the regulation of cell proliferation is being tackled nowadays, mostly by dissecting transition points. Photoinactivating (313 nm light under anoxia) the fidelity of transcripts from segments of DNA wich have been previously bromosubstituted is a new method which our group has recently developed for the analysis of a number of areas of the cycle which behave as if formed of sequential cell cycle controls. The main results obtained in Allium cepa L. meristens, as well as the futures perspectives for this approach, are concisely described.
