And regulation of stem elongation , flower inducement and seeds and fruit development are three very crucial sections in fruit industrial , so it is important to clone the gibberellins biosynthetic enzyme genes and to research on their expressing modes and their regulation roles 而茎的生长，开花的诱导，和果实种子的发育都是果树生产中控制产量和果实品质非常重要的三个环节，因此克隆赤霉素生物合成酶的基因并研究其表达方式及表达调控在果树生产上是非常重要的。
However , glybetaine does not accumulate in many important crop plants such as potato , tomato or rice . among plants glybetaine biosynthetic pathway has been thoroughly characterized in sugar beet and spinach , and biosynthesis is localized in the chloroplast by a two - step oxidation of choline via the intermediate betaine aldehyde . the first enzyme , choline monooxygenase ( cmo ) and the second enzyme are all localized in chloroplast 甘氨酸甜菜碱是由胆碱起始的两部催化反应完成的，第一个酶是胆碱单氧化酶( cmo ) ，已经被纯化，并且它是定位在叶绿体基质中；第二个酶是甜菜碱醛脱氢酶( badh ) ，它也主要定位于叶绿体中。
