摘要
烟碱是烟草最主要的生物碱,直接影响着烟叶的质量及烟叶的可用性。对烟碱合成代谢调控的研究现状进行了综述,包括论述了环境条件、栽培措施、外源激素、烘烤调制等因素对烟碱代谢的调控效果以及烟碱代谢关键基因的研究进展,并提出烟碱合成的根特异性遗传机理、烟碱代谢相关调控基因的分离鉴定及其同源基因的发现是后续的研究方向。
In tobacco（ Nicotiana tabacum L.）,nicotine is a kind of main alkaloids which directly affects the quality and industrial availability of tobacco leaves. The research status of synthesis metabolic regulation of nicotine is reviewed in the regard of the effects of environmental conditions,cultivating practices,exogenous hormones,and baking modulates on nicotine metabolism regulation,meanwhile progress on key genes in nicotine metabolismis elaborated. It is proposed that the root specific genetic mechanism of nicotine synthetics,isolation and identification of relevant regulation genes of nicotine metabolism and the discovery of homologous genes are the directions of future research.
