this study was carried out to investigate the morphological and anatomical aspects of somatic embryogenesis in date palm. lateral bud and shoot tip explants excised from young offshoots were cultured on ms medium with 2,4-d. somatic embryogenesis was in-duced by transferring the calli produced on the same medium without hormones. micro-tome sectioning of paraffin-embedded specimens was carried ...

abstract in this research, the effects of ba with different concentrations (0, 0.5, 1, 1.5, 2, 2.5 and 3 mg/l) in combination with iba (0, 0.01 and 0.1 mg/l) on bud growth and shoot proliferation and tdz with different concentrations (0, 1, 2, 3 and 4 mg/l) in combination with 0 and 0.5 mg/l iba on somatic embryogenesis from different parts of immature cotyledons (proximal, median and distal) w...

We have cloned a SOMATIC EMBRYOGENESIS RECEPTOR KINASE (SERK) gene from Medicago truncatula (MtSERK1) and examined its expression in culture using real time PCR. In the presence of the auxin 1-naphthaleneacetic acid (NAA) alone, root differentiation occurs from the proliferating calli in both the cultured highly embryogenic seed line (2HA) and a low to nonembryogenic seed line (M. truncatula cv...

In plants, complete embryos can develop not only from the zygote, but also from somatic cells in tissue culture. How somatic cells undergo the change in fate to become embryogenic is largely unknown. Proteins, secreted into the culture medium such as endochitinases and arabinogalactan proteins (AGPs) are required for somatic embryogenesis. Here we show that carrot (Daucus carota) AGPs can conta...

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...

Embryogenic callus culture of carrot (Daucus carota L.) was induced from the hypocotyl explants in MS medium supplemented with Casein hydrolysate, 2,4-D and BAP for somatic embryogenesis In vitro cell suspension cultures for high multiplication rate. Embryogenic callus was transferred to liquid basal Murashige and Skoog medium The mature somatic embryos were encapsulated in a Sodium alginate mi...
