Background: Ferulago angulata is an important medicinal plant and endemic to Iran which is an endangered Plant. Objective: The aim of this study was to achieve an efficient method for propagation of this plant and evaluation of essential oil content and composition in habitat. Metthods: Essential oils were extracted by hydrodistillation using Clevenger-type apparatus and its composition was ...

Tree peony (Paeonia ostii) is an ornamental flowering plant that generally recalcitrant to establishment of a mature somatic embryo regeneration system in vitro. Glucose-6-phosphate translocator (GPT) plays important regulatory role embryogenesis plants. In this study, PoGPT1 was cloned, and bioinformatic analysis functional verification the gene were performed. The results showed encoded polyp...

Somatic embryogenesis in Hevea is stimulated when the embryogenesis induction medium contains maltose, rather than glucose, fructose, or sucrose, in equimolarity (Blanc et al., 1999). Kinetic analyses were carried out on various physiological and biochemical indicators over the 8 weeks that the induction phase then expression of somatic embryogenesis can take. Embryogenesis induction in the pre...

Investigations were undertaken on the use of somatic embryogenesis to generate cocoa swollen shoot virus (CSSV) disease free clonal propagules from infected trees. Polymerase chain reaction (PCR) capillary electrophoresis revealed the presence of CSSV in all the callus tissues induced from the CSSV-infected Amelonado cocoa trees (T1, T2 and T4). The virus was transmitted to primary somatic embr...

PIK3CA-Related Overgrowth Spectrum (PROS) refers to rare syndromes, which are characterized by malformations and excessive tissue growth caused somatic mutations in the PIK3CA gene occurring during embryogenesis. This article discusses pathogenesis, clinical picture, diagnosis treatment of these syndromes. Some illustrations used this copied from other resources, rights authors respected not vi...

Abstract Somatic embryogenesis, as a promising biotechnological tool for many conifer trees, has never been applied the Abies nebrodensis species. Although all encouraging results previously obtained by EU LIFE (European program) funded projects in over ten years, critically endangered Sicilian fir remains alarmingly close to extinction. In this study, we reported first protocol of somatic embr...

Abstract Callus formation and somatic embryogenesis in potato varieties are effective ways to obtain an entire plant from a single cell. The implementation of is widely used improving materials creating new biotechnological varieties. In our research, the optimum level 1-naphthaleneacetic acid (NAA) 6-benzyl aminopurine (BAP) was determined callus tissue local Sarnav variety, Desiree variety ta...

ent conccntrations ef 2,4-D, NAA and BAP, large number of somatic cmbryos differentiated When the suspension was cultured for 7 days in the induction medium. The cel]s destined to become somatic embryos divided to form spherical of filamentous proembryos. The fi]amenteus proembryo developed into different shapes of embryos. Somatic embryogenesis began in tlie proembryo stage and preceeded from ...

With the spread of pollinosis caused by sugi (Japanese cedar, Cryptomeria japonica) pollen, use pollen-free somatic seedlings is expected in Japan. However, there a lack knowledge on relationship between abilities during embryogenesis, initial vitro growth traits, and subsequent seedlings. In present study, we provide first basic information embryo maturation efficiency, germination, plantlet c...
