Shuitu Baochi Xuebao, 2007 利用自然降雨影响下的农田为试验样地,分析了降雨前后土壤颗粒组成与养分含量的变化,探讨了流失泥沙颗粒组成与养分的变化特征。结果表明,在降雨后,西瓜地与油菜地表土颗粒组成呈现粘粒与粉粒含量减少,砂粒含量相对增加的趋势;土壤养分含量都有不同程度的下降,其中水解氮与速效磷下降的幅度很大,西瓜地与油菜地水解氮降雨后降幅分别为9.67%和7.99%,速效磷的降幅分别为9.20%和8.76%;全氮养分降幅很小,西瓜地与油菜地分别为2.17%和1.54%;流失泥沙细小颗粒含量与养分含量随时间基本都呈降低的变化趋势 ...

CRISPR/Cas9 mediated genome editing and construction of sgRNA efficiency testing system in C. elegans [PDF]
, 2015 CRISPR/Cas9做为第三代人工核酸内切酶，由于其操作简单、特异性强、及效率高的特性，目前已被广泛用于多种生物的基因组编辑。CRISPR/Cas9介导的基因编辑技术不仅可以用于基因敲除，而且也可以用于精确的基因插入，成为基因功能研究非常有前途的工具。在短短的两年里，已有二十几篇文章先后报道了在秀丽隐杆线虫中利用CRISPR/Cas9对不同基因进行的精确编辑。 本研究中，我们利用CRISPR/Cas9系统，通过Cas9切割导致DNA断裂诱导同源重组，在对dpy-13基因敲除的同时，成功进行了1 ...

Rare Metals, EarlyView.ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...

ELEMENT DISTRIBUTION IN MANGROVES AND SALT-TOLERANT MECHANISM [PDF]
, 2003 对福建九龙江口的秋茄、白骨壤、桐花树、海南东寨港的海莲及广西英罗湾的红海榄 5种红树植物各器官K、Na、Ca、Mg和Cl等元素的分布特征进行了研究 ,并与陆生植物福建武夷山的甜槠进行比较。结果表明 :(1)红树植物体内存在一有效的盐分重新分配机制 ,各器官之间盐分含量差别较大 ,而甜槠植物体内Na分布相对比较均匀 ;(2 )这 5种红树植物主要是通过积累盐分来抵御生境高盐引起的渗透胁迫 ;(3)根系拒盐是所有红树植物最重要的排盐机制 ,在满足细胞渗透调节的前提下 ...

Methods in Ecology and Evolution, EarlyView.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that
