Nucleotide compositions of soluble (sRNA), whole-cell, and in one instance particulate and nonparticulate, RNA of embryos, cotyledons (dark and light-grown), leaves, stems, and roots of Gossypium hirsutum were compared. Evidence of substantial differences in the overall compositions of the RNAs was not obtained. However, a tendency for some plant parts to differ, particularly in sRNA composition, and that of the cotyledons (including particulate and nonparticulate RNA) to change during the formation of chlorophyll, was indicated by small but statistically significant shifts in certain nucleotide components.
比较了棉花胚胎、子叶(黑暗和光照生长)、叶片、茎和根的可溶性(sRNA)、全细胞和在一个实例中的颗粒和非颗粒 RNA 的核苷酸组成。没有获得 RNA 整体组成存在实质性差异的证据。然而,某些植物部分(特别是 sRNA 组成)存在差异的趋势,以及子叶(包括颗粒和非颗粒 RNA)在叶绿素形成过程中发生变化的趋势,表明某些核苷酸成分有较小但具有统计学意义的变化。
