摘要
氮代谢是烤烟体内最重要的代谢途径之一,包括氮的吸收、同化和分配。氮是构成蛋白质、核酸、叶绿素、辅酶、维生素以及烟碱、烟气致香物质的组成成分,对烟叶的产量和质量起着关键作用。然而很难将含氮化合物含量调控在一个适宜的范围,为此,了解烤烟含氮化合物在体内的运输和积累机制尤为重要。本研究围绕国内外对烤烟氮素的吸收、同化和烤烟含氮化合物运输积累的研究进展进行综述,重点介绍了烤烟含氮化合物的运输和积累。这为如何结合当前的研究现状来推动烤烟含氮化合物的研究提供了有价值的线索,同时展望了烤烟氮代谢今后的研究方向。
Nitrogen metabolism is one of the most important metabolic pathways in flue-cured tobacco,including nitrogen absorption,assimilation and distribution.Nitrogen is a constituent of proteins,nucleic acids,chlorophyll,coenzymes,vitamins,nicotine,and smoke aroma substances,and plays a key role in the yield and quality of tobacco leaves.However,it is difficult to control the content of nitrogen-containing compounds in an appropriate range.For this reason,it is particularly important to understand the transport and accumulation mechanism of nitrogen-containing compounds in flue-cured tobacco.This study reviews the research progress of nitrogen absorption and assimilation of flue-cured tobacco and the transportation and accumulation of nitrogen-containing compounds in flue-cured tobacco at home and abroad,focusing on the transportation and accumulation of nitrogen-containing compounds in flue-cured tobacco.This provides valuable clues for how to combine the current research status to promote the research of flue-cured tobacco nitrogenous compounds,and at the same time prospect the future research direction of flue-cured tobacco nitrogen metabolism.
