From reconstruction to C-4 metabolic engineering: a case study for overproduction of polyhydroxybutyrate in bioenergy grasses
(Elsevier, 2018-08)
The compartmentalization of C-4 plants increases photosynthetic efficiency, while constraining how material and energy must flow in leaf tissues. To capture this metabolic phenomenon, a generic plant metabolic reconstruction ...

En plántulas de Erythrina edulis sometidas a deficiencias de N, P, K, Ca y Mg, se evaluaron las variables área foliar, altura de plántula, peso seco de la parte aérea, peso seco de raíz, sintomatología visual y contenido ...
Comparing inoculation methods to evaluate the growth of Xanthomonas axonopodis pv. manihotis on cassava plants
(Universidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biología, 2015-05-01)
Xanthomonas axonopodis pv. manihotis (Xam) es el agente causal del tizón bacteriano de la yuca, una de las principales enfermedades de los cultivos de yuca en América del Sur y África. Hasta ahora, el desarrollo de la ...
Odontopus abdominalis (Coleoptera: Curculionidae): a new avocado pest in northeastern Brazil.
(Universidad del ValleColombia, 2019-12-31)
This is the first report of Odontopus abdominalis as a novel pest in avocado orchards in the Alagoas State, in Northeastern Brazil. Adults feed and bore holes in the leaves, and larvae feed on the mesophyll tissue, boring ...
Lack of costs of herbivory-induced defenses in a wild wheat: Integration of physiological and ecological approaches
(Blackwell Publishing Ltd, 1997)
Aphid infestation triggered a significant induction of hydroxamic acids (Hx) in wild wheat Triticum uniaristatum seedlings in comparison to control seedlings. We hypothesized that indirect costs of Hx induction (expressed ...
Behavioural differences during host selection between alate virginoparae of generalist and tobacco-specialist Myzus persicae
(2005)
Host plant selection and acceptance by aphids involves four consecutive steps: (1) prealighting behaviour, (2) leaf surface exploration and probing of subepidermal tissues, (3) deep probing of plant tissues, and (4) ...

Compatible GLRaV-3 viral infections affect berry ripening decreasing sugar accumulation and anthocyanin biosynthesis in Vitis vinifera
(2011)
Virus infections in grapevine cause important economic losses and affect fruit quality worldwide. Although the phenotypic symptoms associated to viral infections have been described, the molecular plant response triggered ...
In vitro morphogenic responses of vasconcellea chilensis planch. ex a. dc (caricaceae)
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2011)
Multiple shoot formation was induced in vitro on nodal sections excised from adult “palo gordo” plants of Vasconcellea chilensis ex Carica chilensis, in the presence of relatively high levels of thidiazuron (TDZ), indole-3- ...
Development of transgenic lines from a male-sterile potato variety, with potential resistance to tecia solanivora povolny
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2012)
Male sterility is a very important characteristic for environmental safety in genetically modified (GM) plants, particularly in the release of transgenic plants in the centers of origin or high biodiversity areas. In order ...
