Mechanical Stress Elicits Nitric Oxide Formation and DNA Fragmentation in Arabidopsis thaliana
The effect of mechanical stress (centrifugation) on the induction of nitric oxide (NO) formation and DNA fragmentation was investigated in leaf cells of Arabidopsis thaliana. Centrifuged and… Expand

Plant somatic cells have the remarkable ability to regenerate an entire organism. Many species in the genus Kalanchoë, known as “mother of thousands,” develop plantlets on the leaf margins. Using key… Expand
A nitric oxide burst precedes apoptosis in angiosperm and gymnosperm callus cells and foliar tissues.
Leaves and callus of Kalanchoë daigremontiana and Taxus brevifolia were used to investigate nitric oxide-induced apoptosis in plant cells. The effect of nitric oxide (NO) was studied by using a NO… Expand
Effect of different gravity environments on DNA fragmentation and cell death in Kalanchoe leaves.
Different gravity environments have been shown to significantly affect leaf-plantlet formation and asexual reproduction in Kalanchoë daigremontiana Ham. and Perr. In the present work, we investigated… Expand
Factors controlling somatic embryogenesis
Histological and ultrastructural, molecular and elemental distribution changes were investigated during the induction of direct somatic embryogenesis using theCamellia japonica leaf culture system.… Expand
Induction of microspore embryogenesis in Camellia japonica cv. Elegans
Three methods of microspore culture were tested for the induction of microspore embryogenesis in Camellia japonica L. cv. Elegans. Culture was performed on 17 different media consisting of Murashige… Expand
Direct embryo formation in leaves of Camillia japonica L.
SummaryThe culture conditions for direct embryo formation in leaves of Camellia japonica L. were established. An auxin treatment followed by incubation during 11 days in darkness on diluted Murashige… Expand
A scanning electron microscopy and X-ray microanalysis study during induction of morphogenesis in Camellia japonica L.
Abstract A scanning electron microscopy (SEM) study during the induction of direct and indirect morphogenesis (root and embryo formation) from leaves of Camellia japonica L. showed that the induction… Expand
Genetic Differentiation of Portuguese Tea Plant using RAPD Markers
Random amplified polymorphic DNA (RAPD) analysis was used to estimate genetic similarities between Portuguese Ca mel lia sinensis (L.) O. Kuntze (tea plant) ac ces sions and those obtained from the… Expand
Explant region-specific embryogenic competence and plant recovery inCamellia japonica
The culture conditions for direct, indirect, and repetitive embryogenesis were established forCamellia japonica cv. Elegans and cv. Ville de Nantes. Direct embryo production from leaves averaged 15.3… Expand
