摘要

细胞分裂对生物体的生长和修复受损组织非常重要。通过对水稻突变体的筛选，发现了矮小的 korpokkur（kor）突变体，其编码的一种新型蛋白质可能参与了水稻的有丝分裂（包括细胞分裂）。KOR 基因在有丝分裂期表达，KOR 基因缺陷会诱导细胞出现两个核。对 kor 突变体的分析表明，KOR 基因在水稻叶片初生期开始后的一段时间内促进细胞分裂，并维持细胞的正常形态，尤其是在非分裂组织中。此外，kor 突变体从幼叶期向成叶期的过渡出现延迟。未来的研究将揭示有丝分裂缺陷与在 kor 突变体中观察到的其他特征之间的关系。

Rice KORPOKKUR gene is expressed in mitotic cells and regulates pleiotropic features during vegetative phase.

Cell division is important for organisms to grow and repair damaged tissues. A mutant screen in rice has identified dwarf korpokkur (kor) mutants that code for a novel protein potentially involved in mitosis including cytokinesis in rice. The KOR gene is expressed during the mitotic phase and a defect in the KOR gene induces cells with two nuclei. Analysis of kor mutants suggests that the KOR gene promotes cell division in the rice leaf primordia for a period after initiation, and maintains proper cell morphology especially in non-meristematic tissues. Additionally, kor mutants showed a delayed transition from juvenile phase to adult phase. Future research will shed light on the relationship between the mitotic defect and other features observed in the kor mutants.

期刊介绍： Plant Biotechnology is an international, open-access, and online journal, published every three months by the Japanese Society for Plant Biotechnology. The journal, first published in 1984 as the predecessor journal, “Plant Tissue Culture Letters” and became its present form in 1997 when the society name was renamed to Japanese Society for Plant Cell and Molecular Biology, publishes findings in the areas from basic- to application research of plant biotechnology. The aim of Plant Biotechnology is to publish original and high-impact papers, in the most rapid turnaround time for reviewing, on the plant biotechnology including tissue culture, production of specialized metabolites, transgenic technology, and genome editing technology, and also on the related research fields including molecular biology, cell biology, genetics, plant breeding, plant physiology and biochemistry, metabolic engineering, synthetic biology, and bioinformatics.
