Also, fiber serves as an excellent single-celled model for studying fundamental biological proc esses, such as cell elongation and differentiation Plant primary cell walls consist of mainly pectin, hemicellulose and cellulose, and are deposited during the cell expansion phase.

同时，棉纤维细胞也是研究细胞伸长、分化和细胞壁合成等重要生物学现象的理想系统。植物初生细胞壁主要由果胶、半纤维素和纤维素等多糖组成。

The regulation of cell cycle in eukaryote is an important research field in cell biology.

细胞周期调控研究已成为当前生物学领域的一大热门课题，对哺乳动物和酵母细胞周期调控的研究已经非常深入且日臻成熟；植物细胞周期调控研究起步相对较晚但近些年来在该领域也取得了很大的进展。

This is a review of recent studies on the relationship between fire and invasive plant species.

在植物外来种与火生态因子的作用研究中发现，火与外来种的关系随物种生物学特性、火作用的时间、频度、强度不同而不同，火有时会有效地抑制外来种的生长和入侵，有时会促进一些外来种的生长和入侵。

Pigments potent and air temperature are are more important than other factors. The color changing of foliage trees leaf resulted from these comprehensive factors, We must fully respect them in landscape design. Meanwhile, we should make of the bionomics and ecologic habitus of these trees, and make sure to let them show vivid colors and the most beautiful landscape effictiveness in urban environment, ensure the landscape designs more scientific and artistic.

观叶树种的叶色是在许多因素综合作用下发生变化的，在利用观叶树种进行园林景观设计时必须充分考虑影响观叶树种叶色的各种因素，同时对观叶树种的生物学特性和生态习性有深入的了解，使其在城市环境中达到最鲜艳的颜色，产生最佳的景观效果，使园林植物造景更具科学性和艺术性。

Institute of Botany, the Chinese Academy of Sciences, Beijing 100093Abstract Plasmodesma is a supracellular structure of plant organism. It provides a direct cell-to-cell cytoplasmic pathway for material transport and message transference, and converts the colonies of independent cells into an interconnected symplast system.
