영문 초록

Tissue culture is an important practice for industrial seedling production and germplasm conservation as well as transgenic operation. More and more evidences proved that DNA methylation change is usually involved in dedifferentiation, continuous cultivation and redifferentiation during tissue culture. DNA methylation variation increases with prolonging culture duration and increasing subculture times which might induce abnormal phenotype of propagules. The pattern and level of DNA methylation are significantly influenced by explants, growth regulators ents. DNA methylation change might reflect the growth and development processes and stress response of cells or tissues during tissue culture. Elucidation of epigenetic variation mechanism might help to improve tissue culture and transgene technology especially for the woody plant with high regeneration difficulty and low transformation frequency.
