13. Purificação da enzima polifenoloxidase do cafeeiro, sua relação com resistencia a pragas e o controle da sintese de seu principal substrato, o acido clorogenico / Coffee polyphenoloxidase purification, its relation with plague resistance and synthesis control of its maim substrate, chlorogenic acid
Polyphenoloxidase - PPO (EC 1.14.18.1 ou EC 1.10.3.2) is an enzyme with broad distribution among plants and catalyzes the hydroxylation of monophenols to o-diphenols and the oxidation of these to o-diquinones. Its function on plants has been related to defense mechanisms against pathogens and plagues. 5-Caffeoylquinic acid, also known as chlorogenic acid (CG

14. Tomato Ve disease resistance genes encode cell surface-like receptors
In tomato, Ve is implicated in race-specific resistance to infection by Verticillium species causing crop disease. Characterization of the Ve locus involved positional cloning and isolation of two closely linked inverted genes. Expression of individual Ve genes in susceptible potato plants conferred resistance to an aggressive race 1 isolate of Vertici

15. Coping with crowds: Density-dependent disease resistance in desert locusts
Parasite transmission generally exhibits some form of positive density dependence. Thus, as population density increases, so too does the per capita risk of becoming infected. Under such circumstances, natural selection should favor individuals that use cues associated with population density to determine the optimal allocation of resources to disease resist

16. Transgenic Tobacco and Arabidopsis Plants Expressing the Two Multifunctional Sorghum Cytochrome P450 Enzymes, CYP79A1 and CYP71E1, Are Cyanogenic and Accumulate Metabolites Derived from Intermediates in Dhurrin Biosynthesis1
Novel cyanogenic plants have been generated by the simultaneous expression of the two multifunctional sorghum (Sorghum bicolor [L.] Moench) cytochrome P450 enzymes CYP79A1 and CYP71E1 in tobacco (Nicotiana tabacum cv Xanthi) and Arabidopsis under the regulation of the constitutive 35S promoter. CYP79A1 and CYP71E1 catalyze the conversion of the parent amino
