In this study, the leaves of Kalanchoe fedtschenkoi were consecutively macerated with hexane, chloroform, and methanol. These extracts used to assess bioactivities plant. The antimicrobial activity was tested against a panel Gram-positive -negative pathogenic bacterial fungal strains using microdilution method. cytotoxicity K. investigated human-derived macrophage THP-1 cells through MTT assay....

Mitochondrial NAD-malic enzyme (ME) and/or cytosolic/plastidic NADP-ME combined with the cytosolic/plastidic pyruvate orthophosphate dikinase (PPDK) catalyze two key steps during light-period malate decarboxylation that underpin secondary CO(2) fixation in some Crassulacean acid metabolism (CAM) species. We report the generation and phenotypic characterization of transgenic RNA interference lin...

The life cycles of two plant species in the Mediterranean chaparral, the evergreen Arbutus andrachne and the deciduous Rhamnus lycioides, were studied, as were the cycles of two stenophagous whitefly species that live on them, Trialeurodes lauri and Dialeurolobus rhamni, respectively. Trialeurodes lauri is univoltine, diapausing from June to March corresponding to the plant’s leaf dormancy. The...

background: thymus is a widely used medicinal plant in food and pharmaceutical industries. among different species of thymus, t. vulgaris is used more than other species in therapeutic dosage forms. objective: this study was conducted to differentiate various thymus species by tlc fingerprint. methods: in order to identify and differentiate various species of thymus, tlc fingerprints of essenti...

the genus thymus is perennial medicinal plants belong to the lamiaceae familythat is used for different propose in pharmaceutical industry. environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. the purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

In vitro studies of dark (14)CO(2) fixation with isolated cell aggregates of Kalanchoë fedtschenkoi showed that malate synthesized after 20 sec is predominantly (85 to 92%) labeled at carbon 4, while after 20 min only 65 to 69% of the radioactivity was located in this position. The intramolecular labeling pattern of malate could not be changed by supplementing the cells with carboxylation react...
