Initiation of somatic embryogenesis from immature zygotic embryos of oocarpa pine (Pinus oocarpa Schiede ex Schlectendal).
The focus of the current project was to establish somatic embryogenesis protocols for the tropical pine species Pinus oocarpa using immature zygotic embryos (ZEs) as explants. Somatic embryogenesis is best supported by mimicking natural seed-embryo developmental conditions, through a tissue culture medium formulation based on the mineral content of the seed nutritive tissue [megagametophyte (MG...
متن کاملEffect of morphological heterogeneity of somatic embryos of Melia azedarach on conversion into plants.
Embryogenic cultures were initiated from immature Melia azedarach (Meliaceae) zigotic embryos. Explants were induced on Murashige and Skoog (1962) medium with 4.54 microM thidiazuron or 0.45 microM dichlorophenoxyacetic acid. After 6 weeks of culture on induction medium, somatic embryos were categorized in four morphological classes based on the presence of single or fused embryos and if they r...
متن کاملDirect somatic lineage conversion.
The predominant view of embryonic development and cell differentiation has been that rigid and even irreversible epigenetic marks are laid down along the path of cell specialization ensuring the proper silencing of unrelated lineage programmes. This model made the prediction that specialized cell types are stable and cannot be redirected into other lineages. Accordingly, early attempts to chang...
متن کاملOptimizing in vitro Growth Conditions for Magnolia 'Ann'
Significance to Industry: Magnolia (M. liliiflora ‘Nigra’× M. stellata ‘Rosea’) ‘Ann’ (NA 28344; PI 326570) is a member of the ‘Little Girl’ series of magnolias that have become widely popular. Magnolia ‘Ann’ is characterized by a desirable combination of traits including prolific and remontant flowering and a shrubby form. Due to difficulties in propagating magnolias from cuttings or grafting,...
متن کاملRecombinant human activin A promotes development of bovine somatic cell nuclear transfer embryos matured in vitro
To improve the culture system of bovine somatic cell nuclear transfer (SCNT) embryos, we studied the effects of activin A on developmental competence of bovine SCNT embryos during the early development stage based on the traditional culture method, and analyzed the expression level of the genes related to blastocyst hatching (Na/K-ATPase, Glut-1) and related to activin A signalling pathway (Act...
