Intermediary forms of microbodies, glyoxyperoxisomes, are most likely synthesized at the stage of replacement of glyoxysomes by peroxisomes during the greening of fatstoring cells of cucumber cotyledons. This hypothesis is supported by three lines of results: 1. The levels of both glycollate oxidase and malate synthase are increased in the microbody fractions upon illumination of cotyledons. 2. Both peroxisomal and glyoxysomal marker enzymes are localized in organelles which exhibit the same buoyant densities. 3. De novo synthesis of malate synthase takes place even when irradiation already leads to a drastic increase of glycollate oxidase. The amount of malate synthase synthesized is almost identical in the light-induced system and in the dark control.
微体的中间形式，即乙醛酸过氧化物酶体，很可能是在黄瓜子叶贮脂细胞绿化过程中，乙醛酸体被过氧化物酶体替代的阶段合成的。这一假说得到了三方面结果的支持：1. 子叶光照后，微体部分的乙醇酸氧化酶和苹果酸合酶水平均升高。2. 过氧化物酶体和乙醛酸体的标记酶都定位于具有相同浮力密度的细胞器中。3. 即使光照已导致乙醇酸氧化酶急剧增加，苹果酸合酶仍会从头合成。在光诱导系统和黑暗对照中合成的苹果酸合酶量几乎相同。
