作为研究不定器官发生的工具，以下胚轴愈伤组织介导的根再分化为指标表型，筛选到3个拟南芥温度敏感突变体，分别命名为rrd1、rrd2和rrd4。对这些突变体的表型进行了表征，特别考虑到它们的组织培养反应。这些结果表明，RRD1和RRD2基因参与了细胞活跃增殖所需的一些基本过程，而RRD4基因参与了下胚轴外植体愈伤组织启动过程中细胞增殖能力的获得步骤。
As tools for studying adventitious organogenesis, three temperature-sensitive mutants of Arabidopsis thaliana, designated rrd1, rrd2, and rrd4, were isolated by screening with callus-mediated root redifferentiation from hypocotyl explants as an index phenotype. Phenotypes of these mutants were characterized with special regard to their tissue-culture responses. The obtained results suggest that the RRD1 and RRD2 genes participate in some fundamental processes required for active cell proliferation and that the RRD4 gene is involved in the acquisition step of competence for cell proliferation during callus initiation in hypocotyl explants.
