La practicidad, conveniencia y cercanía en algunas ocasiones no están relacionadas con la adquisición de productos alimenticios nutritivos, debido a que los patrones alimentarios de ciertas industrias en la actualidad contienen altos porcentajes de grasas saturadas, sodio, azúcares y calorías. Por este motivo, los consumidores en la actualidad exigen al mercado productos sanos y de gran valor nutricional que aporten proteínas, grasas, vitaminas y minerales a la dieta diaria. En la presente investigación se evaluaron las características fisicoquímicas del yogurt con probiótico Bifidobacterium spp. formulado con jalea de uvilla (Physalis peruviana) y harina de quinua (Chenopodium quinoa), como una alternativa alimentaria. Para ello, se valoró dos niveles de jalea de uvilla 25 % y 30 %, y tres niveles de harina de quinua 0,6 %; 0,8 % y 1 %, frente a un tratamiento control 0 %, aplicando un diseño completamente al azar con arreglo factorial AxB. Se realizó seis formulaciones, las mismas que fueron evaluadas sensorialmente, eligiendo al tratamiento T5 (0,8 % de harina de quinua y 30 % de jalea de uvilla) como el más aceptado. En cuanto a las características fisicoquímicas se obtuvo un pH de 4,28 y acidez de 0,765 %; contenido de sólidos totales 23,47%; proteína 3,23 %; grasa 2,88 %; ceniza 0,79 %; fibra 1,82 %; carbohidratos 67,81 %; vitamina C 0,049 %; potasio 1245,03 mg/kg y calcio 738,23 mg/kg, por tanto, se concluye que es un producto nutritivo y saludable, apto para el consumo humano.

El presente trabajo de investigación tiene como objetivo determinar la concentración y tiempo de exposición de la colchicina para la duplicación del número cromosómico de Physalis peruviana L.  en  condiciones  in  vitro.  Para  tal  fin  primeramente  se  determinó  la  concentración  de  los reguladores de crecimiento para establecer en in vitro brotes de P. peruviana, posteriormente los segmentos nodales fueron sometidos a diferentes concentraciones de colchicina (0.05%, 0.10%  y 0.15 %) durante tres tiempos de exposición (12, 24 y 36 horas). El medio MS suplementado con 0.3 mg/L de BAP permitió establecer en in vitro brotes de P. peruviana. Con la aplicación de 0,05% y 0,10% de colchicina por un tiempo de exposición de 36 horas, se obtuvo plantas cuyos números cromosómicos van de 8n-8=88 y plantas mixoploides, teniendo en cuenta que el número cromosómico en condiciones normales encontrados fue de 4n-4=44 cromosomas. Las características morfológicas y anatómicas de las plantas que duplicaron su número cromosómico encontradas en el presente estudio son de poseer menor altura, mayor área foliar, estomas con menor densidad pero de mayor tamaño y con mayor número de cloroplastos.

Abstract Background Night-break (NB) has been proven to repress flowering of short-day plants (SDPs). Long-noncoding RNAs (lncRNAs) play key roles in plant flowering. However, investigation of the relationship between lncRNAs and NB responses is still limited, especially in Chenopodium quinoa, an important short-day coarse cereal. Results In this study, we performed strand-specific RNA-seq of leaf samples collected from quinoa seedlings treated by SD and NB. A total of 4914 high-confidence lncRNAs were identified, out of which 91 lncRNAs showed specific responses to SD and NB. Based on the expression profiles, we identified 17 positive- and 7 negative-flowering lncRNAs. Co-expression network analysis indicated that 1653 mRNAs were the common targets of both types of flowering lncRNAs. By mapping these targets to the known flowering pathways in model plants, we found some pivotal flowering homologs, including 2 florigen encoding genes (FT (FLOWERING LOCUS T) and TSF (TWIN SISTER of FT) homologs), 3 circadian clock related genes (EARLY FLOWERING 3 (ELF3), LATE ELONGATED HYPOCOTYL (LHY) and ELONGATED HYPOCOTYL 5 (HY5) homologs), 2 photoreceptor genes (PHYTOCHROME A (PHYA) and CRYPTOCHROME1 (CRY1) homologs), 1 B-BOX type CONSTANS (CO) homolog and 1 RELATED TO ABI3/VP1 (RAV1) homolog, were specifically affected by NB and competed by the positive and negative-flowering lncRNAs. We speculated that these potential flowering lncRNAs may mediate quinoa NB responses by modifying the expression of the floral homologous genes. Conclusions Together, the findings in this study will deepen our understanding of the roles of lncRNAs in NB responses, and provide valuable information for functional characterization in future.

Cape Gooseberry

Colombia is the main producer of cape gooseberry (Physalis peruviana L.), a plant known for its various consumption practices and medicinal properties. This plant is generally grown in eroded soils and is considered moderately tolerant to unfavorable conditions, such as nutrient-poor soils or high salt concentrations. Most studies conducted on this plant focus on fruit production and composition because it is the target product, but a small number of studies have been conducted to describe the effect of abiotic stress, e.g., salt stress, on growth and biochemical responses. In order to better understand the mechanism of inherent tolerance of this plant facing salt stress, the present study was conducted to determine the metabolic and growth differences of P. peruviana plants at three different BBCH-based growth substages, varying salt conditions. Hence, plants were independently treated with two NaCl solutions, and growth parameters and LC-ESI-MS-derived semi-quantitative levels of metabolites were then measured and compared between salt treatments per growth substage. A 90 mM NaCl treatment caused the greatest effect on plants, provoking low growth and particular metabolite variations. The treatment discrimination-driving feature classification suggested that glycosylated flavonols increased under 30 mM NaCl at 209 substages, withanolides decreased under 90 mM NaCl at 603 and 703 substages, and up-regulation of a free flavonol at all selected stages can be considered a salt stress response. Findings locate such response into a metabolic context and afford some insights into the plant response associated with antioxidant compound up-regulation.
