Organogenesis and neoformant plantlet production were studied by culturing the different parts of mature embryo including radicle and proximal and distal parts of cotyledon of Mission and Kroneiki cultivars. Different parts of embryos were cultures in OMc medium containing growth regulators, such as indole butyric acid (IBA) and 2-isopentenyl adenine (2-ip) or IBA and naphthalene acetic acid (N...

Several reports have suggested that mesenchymal glycosaminoglycans (GAG) may be involved in the regulatory role of epithelial differentiation. Some researchers have pointed out that exogenous GAG affects extracellular GAG accumulation. We have therefore examined the effect of added GAG on two typical processes of avian skin differentiation: keratinization and feather formation. Glycosaminoglyca...

Origanum acutidens (HAND.-MAZZ.) IETSWAART is a promising ornamental plant that can be widely used in landscape management. It is endemic to Eastern Anatolian region of Turkey. Tissue culture has not been used to micropropagate it. The study reports stem node explants from one-week-old seedlings of the plant for successful micropropagation. The stem nodes were cultured on MS medium containing 0...

viously reported (Paine et al., 1979b), in the loss of 60% of their total nucleotide content, which is due to a loss of NAD+ and NADH (referred to as NAD throughout) (Table 1). Culture of hepatocytes for 24 h in media containing hyperphysiological concentrations of known precursors of NAD (Ijichi et al., 1966; Blake et al., 1967) shows that only culture medium containing nicotinamide is able to...

The present investigation was carried out to study the In vitro shoot multiplication and callogenesis in Gladiolus. For this purpose, cormel, meristem and leaf explants were chosen. Different concentrations of BAP i. e., 0.5, 1.0, 1.5, 2.0 or 2.5 mgL (2.22, 4.44, 6.66, 8.88 or 11.10 μM) were supplemented to MS medium. Both cormel and meristem explants showed maximum multiplication on MS medium ...

Background: Nitric oxide is a free radical that recently has emerged as a key signaling molecule in regulating important physiological processes in plants. Objective: In this work, sodium nitroprusside (SNP) was utilized as the donor of nitric oxide to investigate the effects of exogenous nitric oxide on essential oil, rosmarinic acid and antioxidant activity of in vitro-cultured Melissa offi...
