摘要:
开花是植物生命周期中必不可少的阶段,它决定了植物能否顺利繁殖后代,同时也与人类生活息息相关。植物开花受温度、光照强度、日照长短等外界环境的影响,其中温度的调控尤为重要。近几十年来,国内外学者对温度诱导植物开花的分子机理的研究不断深入,研究结果日新月异,揭示了温度调控植物开花的多条途径。本文系统地总结了温度调控植物开花(主要包括温度传感、春化和环境温度途径)的研究进展,主要对近期的研究热点温度传感器、开花促进因子、开花抑制因子进行了详细的阐述。结果表明:1、植物主要通过响应温度的组蛋白修饰、冷诱导转录因子以及温度感应的关键基因来感知温度,Rea L在已知的春化和环境温度途径的基础上提出了4条温度传感途径:以月(L),以天(S),以小时(C)以及昼夜时钟(D)为单位的路径,简称LSCD调节模型,揭示了VIN3表达中的分布式热传感器输入。2、主要的开花抑制因子有SVP、FLM-β、FLC、FRI-C复合物、SPEN3、KHD1、miR156、PEP1和PEP2,这些负性调节因子的活性被一组促花因子抵消,这些促花因子包括PIF4(在SD条件下)、FCA、PRC2复合物、COOLAIR、COLDAIR、COLDWRAP、miR172和FT。3、FLC的表达受FLC的反义转录物COOLAIR的抑制,并由COLDAIR和COLDWRAP来维持这种抑制,且 FLC还受FT及互作蛋白FD的负反馈调节。最后对该领域的研究成果和发展进行了讨论与展望,认为未来对开花机制的研究应着重从温度依赖的选择性剪接、蛋白质修饰和降解或核小体周围的DNA包裹、对自然条件下环境温度的长期和短期变化作出反应和晚抽薹基因等方面来进行。
Abstract:
Flowering is an indispensable stage in the life cycle of plants. It determines whether plant can successfully produce offspring and is closely related to human life. Plant flowering is under the control of environmental factors such as temperature, light intensity and day length, among which temperature regulation is particularly important. In recent decades, scholars at home and abroad have been deeply studying the molecular mechanism of plant flowering regulated by temperature, the research results have been changing with each passing day, and revealing many paths of temperature-regulated plant flowering. In this review, we systematically summarized the research progress of temperature-regulated plant flowering, including temperature sensing, vernalization and environmental temperature pathways, and described recent research hotspots in temperature sensors, flowering promoting factors and flowering suppressing factors in great detail. First, recent studies revealed that plants primarily through many key genes which associate with histone modifications, cold-induced transcription factors or temperature-sensitive genes to respond to temperature signal. ReaL et al proposed four temperature sensing pathways based on vernalization and ambient temperature pathways: Months (L), Days (S), Hours (C) and Day and Night clocks (D). These pathways together refer to as LSCD adjustment model, revealing the distributed thermal sensor input in VIN3 expression. Second, the main flowering inhibitors including SVP, FLM-β, FLC , FRI-C complex, SPEN3, KHD1, miR156, PEP1 and PEP2 . The activity of these negative regulators is offset by a group of flower-promoting factors. Flower-promoting factors include PIF4 (under SD conditions), FCA, PRC2 complex, COOLAIR, COLDAIR, COLDWRAP, miR172 and FT. Third, the expression of FLC is inhibited by FLC antisense transcript COOLAIR, and this inhibition is maintained by COLDAIR and COLDWRAP, and FLC is also regulated by negative feedback of FT and interacting protein FD. At the end of this paper, we discussed future process can focus on flowering mechanisms that result from temperature-dependent alternative splicing, protein modification and degradation or DNA encapsulation around nucleosomes. More importantly, it needs to pay more attention on genes that response to long-term and short-term temperature changes under natural conditions and genes that related in late twitching.
