Characterization of three heat-shock-protein genes and their developmental regulation during somatic embryogenesis in white spruce [Picea glauca (Moench) Voss].

abstract：:The total isolation procedure for isolation of auxotrophic and temperature-sensitive mutants was applied to haploid mesophyll protoplasts of Hyoscyamus muticus after treatment with N-methyl-N'-nitro-N-nitrosoguanidine. Twelve variant clones were isolated after screening a total of 29,000 clones. Two are auxotrophic fo...
