Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Developing multifunctional luminescent materials with tunable spectra is crucial for plant lighting and information–security applications. To address the critical requirement of plant photosynthesis for blue and red spectral components, a novel lead‐free double perovskite Cs2NaGdCl6: Sb3+, Pr3+ phosphor was designed and synthesized via a ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

, 2009 生物结皮广泛分布于干旱、半干旱区,强烈影响着土壤表层理化特性,进而对种子散布、萌发和定居产生影响。目前关于生物结皮与植物种子萌发关系的研究结论存在争议。该文通过室内人工控制实验,研究了生物结皮对古尔班通古特沙漠5种具不同种子形态特征的荒漠植物白梭梭(Haloxylon persicum)、蛇麻黄(Ephedra distachya)、角果藜(Ceratocarpus arenaarius)、涩芥(Malcolmia africana)和狭果鹤虱(Lappula semiglabra)的种子萌发的影响 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

, 2010 为了筛选九寨沟旅游退化地段林下植被恢复的适宜物种,并揭示乡土植物种子基本性状特征,研究了九寨沟28种观赏性乡土植物种子基本特征(长宽、种皮厚度、千粒重、活力、萌发率)以及低温层积提高种子发芽能力的作用。调查研究结果是:1)28种植物种子中4种为小种子(9.9mg)。小种子均出现萌发,与小种子相比,种子休眠普遍存在于中等大小和大的种子中。2)77%的物种种子活力较高(>72%),但仅有7种常规条件下能萌发;窄叶鲜卑花的萌发率最高,达到80%左右,6种植物的萌发率3%～50%。3)低温层积显著提高了蔷薇 ...
