摘  要:GLKs(GOLDEN 2-LIKEs)是一类植物特有的转录因子,靶向调控光合作用相关基因的表达,调控叶绿体的发育、分化并维持其机能,并参与调节果实的营养积累、叶片衰老、免疫反应及逆境胁迫应答等。GLKs受多种激素或环境因子的影响,是植物细胞调控网络的关键节点,也是改造作物光合能力的重要基因。基于国内外在植物GLKs研究中取得的众多进展,文中全面阐述了GLKs基因的生物学功能、分子机制及其育种实践,并构建GLKs介导的信号网络模型,为后期GLKs的理论与应用研究提供借鉴。GLKs(GOLDEN 2-LIKEs)are a group of plant-specific transcription factors regulating the chloroplast biogenesis,differentiation and function maintains by triggering the expression of the photosynthesis-associated nuclear genes(PhANGs).The GLKs also play important roles in nutrient’s accumulation in fruits,leaf senescence,immunity and abiotic stress response.The expression of GLK genes were affected by multiple hormones or environmental factors.Therefore,GLKs were considered as the key nodes of regulatory network in plant cells,and potential candidates to improve the photosynthetic capacity of crops.Since numerous researches of GLKs have been reported in plants,the biological function,molecular mechanism of GLKs genes and its applications in breeding were summarized and a GLK-mediated signaling network model was developed.This review may facilitate future research and application of GLKs.
