    The aim of this study was to characterize the transcriptional expression patterns of a new lea gene isolated in a previous work from C. annuum cv. caballero seeds when osmoprimed with PEG and GA3. Capsicum annuum is one of the main horticultural crops in México and routinely their seeds have problems when germinating. To correct this problem, osmopriming treatments based on PEG and GA has been used to improve their vigor. Osmopriming is a strategy developed to improve vigor during seed storage, which causes a reduction in germinability and seedling establishment. Osmopriming consists of the pre-imbibition of seeds in a solution containing an inert osmotic agent such as polyethylene glycol (PEG). In combination with PEG, several other compounds such as gibberellic acid (GA) can be used in order to improve the vigor of seeds. Several ESTs with high induced expression in the osmopriming treatment displayed high homology to LEA proteins and one of them corresponded to a complete cDNA coding a new LEA protein of 73 amino acids (Calea 73 gene). This gene was highly induced in osmoprimed treatments in which KNO3 instead of GA3 was used in combination with PEG on C. annuum cv. caballero seeds. To our knowledge this is the shortest lea gene reported so far. © 2008 Asian Network for Scientific Information

    Agronomic traits associated to yield and quality in oat seeds

    This study aimed the evaluation of the role of plant density and fertilization on yield and quality of oat seeds. Factors as plant density and type of fertilization (nitrogen and phosphoric) were evaluated in the study. Measurements of yield, vigor, germination, volumetric weight, weight of 1000 seeds and protein content were determined in oat seeds. Present results showed that in order to increase yield and seed quality in oat, it is necessary a plant density of 40 kg ha -1, as well as nitrogen fertilization of 60 kg ha -1. Besides, phosphoric fertilization of 80-120 kg ha -1 increased both yield and seed quality. © 2008 Asian Network for Scientific Information

    This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies ,will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction - Quantum Chromodynamics (QCD) - in extreme conditions of temperature, density and parton momentum fraction (low-x). This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high pT hadrons which yield "tomographic" information of the hottest and densest phases of the reaction.0info:eu-repo/semantics/publishe
