后生植物

This Review discusses current advances in our understanding of the origin, biogenesis, and mode of action of plant miRNAs and draws comparisons with their metazoan counterparts.

本文对植物miRNAs的生物起源和作用模式进行了讨论，并对与它们配对的后生动物进行了对比。

The contemporary radiations of phytoplankton and benthic metaphyte probably made a significant contribution to the Early Cambrian explosion of animals.

这一时期浮游微生物和后生植物的共同繁盛可能为早寒武世"澄江生物群"的爆发奠定了生态基础。

Scalariform thickening A type of secondary wall formation consisting of interlaced helical bands of thickening giving a ladderlike formation. It allows for very little further extension, and is found in tissues such as metaxylem tracheids and vessels, which do not elongate after maturation.

梯纹加厚：是植物细胞次生壁的一种形态结构，壁由加厚过程中相互交错成梯状形态的螺旋带形成，其可延伸性很小，多存在于后生木质部管胞和导管等一些成熟后便不再延伸的管状分子中。

Therefore, the appearance of macroscopic algae not only improved the environment and played an essential support for the growth and propagation of the metazoan which depended on oxygen, but also provided a new food source that served as a new basis in the ecosystem for metazoans evolution and development.

因此，陡山沱期的宏体植物不仅改善了环境，为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持，而且作为生态系统中的必要基础，为宏体后生动物的快速发展和演化提供了一个新的食物源。

These results indicate that oxylipin biosynthetic genes were present in the last common ancestor of plants and animals, but were subsequently lost in all metazoan lineages except Placozoa, Cnidaria and Cephalochordata.

另外，比较研究表明，羟脂生物合成基因存在于植物和动物的最后共同祖先中，但在演化过程中在除少数几个后生动物分支以外的所有动物身上都丢失了。

Gene silencing is a kind of epigenetic phenomenon discovered in transgenic plants in recent years.

基因沉默是近几年来在转基因植物中发现的一种后生遗传现象。

On the section, the Wenghui Biota can be redivided into Globusphyton,Sectoralga-Longifuniculum,Cucullus,Beltanelliformis,and Baculiphyca- Gesinella Communities, from below to above. The change and evolution of these communities show the relation the biota and microenvironment, and indicates the relationship macro-plants with metazoans.

在时间纵向上可依次分为Globusphyton ， Sectoralga-Longifuniculum ， Cucullus ， Beltanelliformis ，Baculiphyca-Gesinella等5个群落，反映出生物群落与环境的相关性以及宏体后生动物与植物之间的相关性和规律性。

This influx of terrestrial carbon is not apparent in carbonates older than 850 Myr, so we infer an explosion of photosynthesizing communities on late Precambrian land surfaces.

这样一个产生氧和植物的事件，甚至可能要对从前寒武纪的一个实质上为微生物的世界向寒武纪的一个后生动物世界的关键过渡负间接责任。

The discovery of the diverse-shaped macrofossil assemblages from the Jiucheng Member in eastern Yunnan indicates the diversification and radiation of metaphytes during the latest Ediacaran Period.

滇东地区旧城段形态多样的宏体藻类化石的发现，进一步表明埃迪卡拉纪末期存在后生植物的多样化发展。

The macro-organisms, including macro-plants, metazoans and trace fossils, 30 species of 23 genera and 4 macroalgal holdfasts, which are collected from Southeast Zhongqing and Northwest Guizhou, are described herein.

宏体生物广泛地生活于扬子地区伊迪卡拉纪陡山沱期古海洋中，描述了产自渝东南和黔东北伊迪卡拉系陡山沱组的宏体生物(包括宏体植物、后生动物和遗迹化石)共30属，23种，4个不明固着器，其中包括4个新属，5个新种，2个新修正属和1个新修正种。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
