| 中文摘要: |
| 番茄作为重要的蔬菜作物及模式植物之一,在现代农业与科研中具有重要的地位。叶片作为植物发育的营养器官,叶片的颜色会影响光合作用和呼吸作用的效率,与番茄果实产量密切相关。叶片黄化突变具有复杂的分子机制,突变基因可以直接或间接干扰色素的合成和稳定性,进而引起叶片颜色的黄化。本文从叶色突变体类型、叶色突变体的生理研究、叶色突变体形成机制、多组学分析及表观遗传学等几个方面对叶片黄化基因定位与基因功能研究进展进行综述,探讨了目前番茄叶片黄化基因中存在的问题并进行展望,为番茄育种实践提供理论依据和材料。 |
| 英文摘要: |
| Tomatoes, as an important vegetable crop and model plant, play an important role in modern agriculture and scientific research. As a nutrient organ for plant development, the color of leaves can affect the efficiency of photosynthesis and respiration, and is closely related to tomato fruit yield. Leaf yellowing mutations have complex molecular mechanisms, and mutated genes can directly or indirectly interfere with pigment synthesis and stability, leading to yellowing of leaf color. This article reviews the research progress on the localization and cloning of tomato leaf yellowing genes from several aspects, including leaf color mutant types, physiological studies of leaf color mutants, formation mechanisms of leaf color mutants, multi omics analysis, and epigenetics. It explores the existing problems in tomato leaf yellowing genes and provides prospects. These studies will provide theoretical basis and materials for tomato breeding practice. |
