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»

Leaf carbon assimilation and molecular phylogeny in Cattleya species (Orchidaceae)

    V. Andrade-Souza, A.-A.F. Almeida, R.X. Corrêa, M.A. Costa,\M.S. Mielke and F.P. Gomes

We examined leaf CO2 assimilation and how it varied among species within the orchid genus Cattleya. Measurements of CO2 assimilation and maximum quantum yield of PS II (Fv/Fm) were made for mature leaves of nine species using a portable system for photosyn­thesis measurement and a portable fluorometer. Leaf area was measured with an area meter, and the specific leaf mass was determined. DNA.. Read More»

Changes in protein profile detected in seedlings of Caesalpinia peltophoroides (Fabaceae) after exposure to high concentration of cadmium

    L.M.C. Gomes A.S. Gesteira A.-A.F. de Almeida A.V. de Castro L.O. Dias C.P. Pirovani F.P. Gomes

Sibipiruna (Caesalpinia peltophoroides Benth) is a tree of the Brazilian Atlantic Forest. It is a flowering ornamental tree widely planted throughout Brazil and indicated for restoration of degraded areas. We examined protein profile changes in leaves of seedlings of C. peltophoroides grown in nutrient solution under greenhouse conditions, after exposure to cadmium (Cd; 32 mg/L). A two-dimensio..
