Effect Of Polyamines On Somatic Embryogenesis Via Mature Embryo In Wheat, Murat Aydin, Arash Hossein Pour, Kami̇l Hali̇loğlu, Meti̇n Tosun
Turkish Journal of Biology
Plant tissue culture via somatic embryogenesis plays a key role in wheat genetic transformation studies. Therefore, the production of embryogenic calli with a high regeneration capacity is a prerequisite for efficient plant regeneration. Although immature embryos are the best type of explants for plant regeneration via somatic embryogenesis, the use of mature embryos has remarkable advantages compared to immature embryos as explants. However, the regeneration capacity of mature embryos is still lower than that of immature embryos. Plant regeneration from somatic embryos can only occur when they are mature enough. Moreover, the maturation of somatic embryos and their conversion into …
