In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...
In vitro regeneration of two cultivars of carnation, namely, ‘Nelson’ and ‘Impulse’ was studied through direct somatic embryogenesis. Somatic embryos were formed directly on petal explants cultured on Murashige and Skoog (MS) medium containing different concentrations (0.2, 0.5, 1, 2, 4, 6 mg 1-1) of picloram. Maximum embryogenesis was obtained with 1 and 2 mg/l picloram. Globular shaped embryo...

to produce embryogenic callus and somatic embryos, tendril explants were collected and cultured in ms medium supplemented with various concentrations of hormones. after one month most of explants produced callus. the highest percent of embryogenic callus obtained in ms medium supplemented with 4.5 µm bap and 1µm 2,4-d. production of somatic embryos was depended on genotype and medium. yaghouti ...
Background: At the outset of the somatic cell nuclear transfer (SCNT) process, the chromatin structure of the somatic cell which governs its state of differentiation undergoes dramatic changes, called reprogramming, and is compelled back to the embryonic stage. However, the overall epigenetic makeup of the resultant cloned embryos has been acknowledged far different from the fertilized embryos....
Somatic embryogenesis is affected by several factors. In this research project, we studied the effect of explant size, wounding and desiccation treatments on somatic embryogenesis and their conversion into plantlet among three genotypes of soybean. The explants were sampled from immature embryos of soybean in three different sizes (3, 5 & 7 mm) with wounding treatment on half of each, and then ...

somatic embryos of persian walnut were transformed with two strains of agrobacterium tumefaciens i.e. lba4404 and c58, and two plasmids, namely, pbi121 with nptii and gus genes for improving the transformation protocol, and p6u-ubi-fvti plasmid containing the hpt and fld genes. the transformation frequency was 10%. pcr and rt-pcr analysis proved the presence and expression of the genes. the tra...
somatic embryogenesis was initiated in c. sativus l. from shoot meristems on ls medium containing bap (2×10-5 m)+naa (2×10-5 m). various stages of somatic embryogenesis were observed in the same medium and the development was asynchronous. somatic embryo development proceeded through well recognized sequences (globular to embryoids) with clearly discernible bipolar regions. matured embryos coul...
