Effect of overexpression of citrus 9-cis-epoxycarotenoid dioxygenase 3 (CsNCED3) on the physiological response to drought stress in transgenic tobacco
9-cis-epoxycarotenoid dioxygenase (NCED) encodes a key enzyme in abscisic acid (ABA) biosynthesis. Little is known regarding the regulation of stress response by NCEDs at physiological levels. In the present study, we generated transgenic tobacco overexpressing an NCED3 ortholog from citrus (CsNCED3) and investigated its relevance in the regulation of drought stress.. Read More»

Physical location of the carotenoid biosynthesis genes Psy and �²-Lcy in Capsicum annuum (Solanaceae) using heterologous probes from Citrus sinensis (Rutaceae)
Carotenoids are responsible for a range of fruit colors in different hot pepper (Capsicum) varieties, from white to deep red. Color traits are genetically determined by three loci, Y, C1, and C2, which are associated with carotenogenic genes. Although such genes have been localized on genetic maps of Capsicum and anchored in Lycopersicon and Solanum, physical mappin.. Read More»

TcCYS4, a cystatin from cocoa, reduces necrosis triggered by MpNEP2 in tobacco plants
In Brazil, most cocoa bean production occurs in Southern Bahia. Witches’ broom disease arrived in this area in 1989 and has since caused heavy losses in production. The disease is caused by the basidiomycete fungus Moniliophthora perniciosa, a hemibiotrophic fungus that produces the necrosis and ethylene-inducting protein (MpNEP2) during infection; th..

Phosphate-induced-1 gene from Eucalyptus (EgPHI-1) enhances osmotic stress tolerance in transgenic tobacco.
Environmental stresses such as drought, freezing, and high salinity induce osmotic stress in plant cells. The plant response to osmotic stress involves a number of physiological and developmental changes, which are made possible, in part, by the modulation of the expression of specific genes. Phosphate-induced-1 gene (PHI-1) was first isolated from phosphate-treated.. Read More»

Proteomic response of Moniliophthora perniciosa exposed to pathogenesis-related protein-10 from Theobroma cacao
TcPR-10, a member of the pathogenesis-related protein 10 family, was identified in EST library of interactions between Theobroma cacao and Moniliophthora perniciosa. TcPR-10 has been shown to have antifungal and ribonuclease activities in vitro. This study aimed to identify proteins that are differentially expressed in M. perniciosa in response to TcPR-10 through a proteomic analysis. The funga.. Read More»
