Isolation of a cDNA clone for a cytokinin-repressed gene in excised cucumber cotyledons.

abstract：MAIN CONCLUSION:The analysis of early generations of triticale showed numerous rearrangements of the genome. Complexed transformation included loss of chromosomes, t-heterochromatin content changes and the emergence of retrotransposons in new locations. This study investigated certain aspects of genomic transformations...
