The callus induction and plant regeneration of wheat mature embryos under osmotic stress;

In order to study the feasibility of wheat mature embryos as explants for callus induction and plant regeneration,10 different genotypes commom winter wheat(Triticum aestivum)mature embryos were used under different culturing conditions of different medium and different treatment.

Studies on DNA Methylation during Dedifferentiation of Mature Wheat Embryos;

) in Henan Province, We analyzed the expressions of genes related to transcription factor families and their target genes during dedifferentiation of mature wheat embryos at transcriptional level with a Affymetrix wheat GeneChip.

Different expression of gene related to amino acid metabolism were analyzed in order to elucidated their roles in mature wheat embryos dedifferentiation.

) as experiment material to study the process of mature wheat embryos dedifferentiation from morphology, cell structure to gene expression level.

Factors affecting tissue culture responses of mature seeds in tall fescue (Festuca arundinacea Schreb.).Ⅰ.The effects of multiple factors on callus induction;

Using mature seeds of Eucommia ulmoides Oliv.

2mg/L 6-BA were propitious to callus induction from mature seeds; the fresh weight of callus reaches the largest.
