Zúñiga Navarro, Gustavo; Argandoña Cortés, Víctor; Corcuera, Luis (1989)The concentration of proline was found to be similar in the epidermis, the vascular bundles and mesophyll parenchyma protoplasts of barley seedlings. In stressed leaves, proline was accumulated mainly in the vascular bundles ...

Zúñiga, Gustavo E.; Corcuera, Luis J. (1986)Gramine (N,N‐Dimethyl‐3‐aminomethylindole) content in various barley cultivars varied from 0 to 2.6 mmoles/kg fresh weight. Those cultivars which were lacking gramine were the most susceptible to the aphid Rhopalosiphum ...

Effect of gramine on the feeding behavior of the aphids Schizaphis graminum and Rhopalosiphum padi Zúñiga, Gustavo E.; Varanda, Elenice M.; Corcuera, Luis J. (1988)The effects of the indole alkaloid gramine on the behavior of the aphids Schizaphis graminum and Rhopalosiphum padi feeding on barley seedlings and on artificial diets were studied. On barley cv. F. Union, which lacks ...

Marino Cabrera, Hernán; Argandoña Cortés, Victor; Zúñiga Navarro, Gustavo; Corcuera, Luis (1995)To compare the effects of aphid infestation with some effects of wounding and drought-stress, several physiological parameters and metabolite concentrations were measured in infested, mechanically wounded or water-stressed ...

Massardo, Francisca; Zúñiga, Gustavo E.; Ptrez, Luz M.; Corcuerat, Luis J. (1994)DIMBOA, the main hydroxamic acid in maize and wheat, is found mainly as a glucoside in intact maize plants; when the tissue is damaged a β-glucosidase releases DIMBOA from DIMBOA-glucoside. The effects of DIMBOA and its ...

Espinoza, Analia; Contreras, Rodrigo; Zúñiga, Gustavo E.; Herrera, Raul; Moya León, María Alejandra; Norambuena Morales, Lorena; Handford, Michael (Frontiers Media, 2016)White Chilean strawberries (Fragaria chiloensis) are non-climacteric fruits, with an exotic color and aroma. In order to discover genes involved in the development of these fruits, we identified a fragment of a gene encoding ...

Zúñiga Navarro, Gustavo; Corcuera Pérez, Luis (Pergamon-Elsevier, 1987)Water deficit increased susceptibility of barley to the aphid Schizaphis graminum. Proline and glycine-betaine accumulated in the stressed plants. These compounds were incorporated into artificial diets to test their effects ...

Zúñiga, Gustavo E.; Argandoña, Víctor H.; Niemeyer, Hermann M.; Corcuera, Luis J. (1983)The content of two hydroxamic acids, 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) and 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), in cultivated and wild species of Gramineae was determined. Zea mays and Triticum ...

Zúñiga, Gustavo E.; Copaja, Sylvia V.; Bravo, Hector R.; Argandoña, Victor H. (1990)Hydroxamic acids were quantified by HPLC in leaves of one-week-old seedlings and in 30 day-old callus tissues of four wheat cultivars. Leaves accumulated preferentially 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). ...

Venegas, Maximiliano; Barahona, Salvador; González, Ana María; Sepúlveda, Dionisia; Zúñiga, Gustavo E.; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor; Alcaíno Gorman, Jennifer (Frontiers Media, 2020)Xanthophyllomyces dendrorhoussynthesizes astaxanthin, a carotenoid used in aquaculture. Astaxanthin is synthesized from metabolites of the mevalonate pathway, which are also precursors for sterols biosynthesis. The ...
