Antioxidant enzyme activity in germination of Dalbergia spruceana seeds under different temperatures
Land use changes by human activities have been the main causes of habitats and wildlife population degradation. In the Tehuantepec Isthmus in Oaxaca, the tropical habitat of the porcupine Sphiggurus mexicanus has been subject to vegetation and land use changes, causing its reduction and fragmentation. In this study, we estimated vegetation cover and land use (δn) change rates and assessed habit...
Uterine muscle contraction is dependent on external Ca2+ and Ca2+ release from cytoplasmic storage sites. In this study, the mechanism of Ca2+ mobilization in uterine muscle cells by glycoside, dalsaxini, isolated from the root of D. Saxatilis was investigated in the rat. Uterine muscle contractility stimulated by dalsaxin was concentration dependent (ED50 0.13 mg/ml) and was significantly atte...
The motile zoospores of the damping-off pathogen Aphanomyces cochlioides aggregate on host plants (e.g., sugar beet, spinach) guided by the host-specific plant signal cochliophilin A before infection. To assess the potential role of secondary metabolites in nonhost resistance, acetone extracts of 200 nonhost traditional medicinal plants from Chinese and Bangladeshi origins were tested for the m...
The pantropical genus Dalbergia includes more than 250 species. Phylogenetic studies of the group are scarce and have only included two or three species distributed in Mexico. We obtained herbarium samples Mexican, Central American, South American (sourced from MEXU). In addition, sequences GenBank accessions were used to complement study. Using internal transcribed spacer ( ITS ), matK rbcL 38...
