In cotyledon, on one hand, very weak GUS staining was observed in PARF8:GUS, but very strong was found in phyA-209 PARF8:GUS. In the shoot apical meristem, hypocotyle and root tip, on the other hand, phyA-209 PARF8:GUS exhibited weaker GUS activity than PARF8:GUS. Interestedly the same expression patterns of ARF8 resulting from disruption of PhyA have been observed in dark, white-light and far-red-light conditions.

结果表明，无论在黑暗、白光和远红光条件下，PhyA突变均明显提高幼苗子叶和叶片中ARF8的表达水平，但明显降低幼苗下胚轴、茎尖和根尖中的表达水平。

Efficient usage of the main storage material in megagametophyte before it falls off from seedling is important for seed germination of Pinus edulis Engelm.. We examined and compared lipid usage in both megagametophyte and cotyledon with electromicroscopic technique, the length, dry weight, starch content and FBPase activities of each part of the seedling were measured and compared.

采用电镜技术观察了黑暗中萌发中食松子叶和提供营养的雌配子体中脂肪体和与脂肪利用有关的乙醛酸循环体的变化，测量比较了子叶、下胚轴、根的长度、干重、淀粉含量，以及果糖1，6二磷酸酶的活性变化，对贮藏物质脂类、淀粉的利用及与生长的关系进行了分析。
