| 摘 要： | 利用土钻法对不同封育年限下石灰岩山地植被细根生物量进行对比研究。结果表明院封育5 年林分细根
生物量为6.6287 t/hm2，封育10 年林分细根生物量为2.3063 t/hm2，封育20 年林分细根生物量为3.1316 t/hm2，封育
30 年林分细根生物量为2.8316 t/hm2；不同封育年限下细根生物量均随着土层深度的增加而降低，0~10 cm 土层的细
根生物量明显高于其他两个土层；不同封育年限细根生物量年动态变化均呈现双峰型。

Research progress of degradome sequencing method for plants |

| Abstract: | miRNA target identification has been one of the study hotspots in plants. Recently, a high-throughput
technique known as degradome sequencing has made it possible to sequence mRNA cleavage products on a large-scale.
Computational methods now exist to use these data to find targets of conserved and newly identified miRNAs. This
technology has been applied to study the regulation modes of miRNAs on their target genes during plant growth,
development and environmental stress responses. In this paper, the protocols, analysis tools and application examples of
degradome sequencing in plants were reviewed to provide useful knowledge background for studying gene regulation
network. |
