Shuitu Baochi Xuebao, 2022 为探究不同植物根-土复合体抗剪强度的差异性及各因素对其的影响程度, 选取汶川县针叶林、阔叶林、灌丛、草地4种不同植被覆盖区为研究区, 通过野外制取16种优势植物根-土复合体和无根裸土原状试样并开展室内快剪试验。分析了汶川县典型植物根系对土体抗剪强度和抗变形能力的增强作用, 运用灰色关联法分析影响复合体抗剪强度的因素。结果表明: (1)16种植物根系均能在一定程度上提高土体抗剪强度和抗变形能力, 且主要通过提高土体黏聚力增强其抗剪强度; 根-土复合体黏聚力均大于裸土, 其增幅为6.09%~153.27%,

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 ...

Shuitu Baochi Xuebao目的为探究不同灌草植物根系生物力学特性的差异性及其相互关系。方法选取黄土高原地区6种常见的水土保持灌草植物，系统研究其根系形态、化学成分和抗拉力学特性及其相互关系。结果1）6种灌草植物根系直径（D）主要以细根（<2 mm）为主，根长密度（RLD）、根表面积密度（RSAD）和根生物量密度（RMD）不同土层深度分布呈显著差异性（p<0.05）；白羊草的D、RLD、RSAD和RMD与其他5种植物存在显著差异性（p<0.05）。2）6种植物根系平均抗拉强度（Tr），白羊草根系平均Tr分别是苔草、

New Phytologist, Volume 250, Issue 2, Page 762-787, April 2026.Summary B‐box (BBX) proteins were initially characterized as transcription factors connecting light signaling to the regulation of flowering time and seedling photomorphogenesis. However, over the last decade, increasing evidence has shown that they integrate light and hormone signaling, modulating multiple physiological processes during plant life. In

New Phytologist, Volume 250, Issue 2, Page 1313-1329, April 2026.Summary With current climate trajectories, tree populations will encounter novel selection pressures that risk local extinction if they are unable to acclimate or adapt. Within a reciprocal transplant experiment with Quercus macrocarpa L. established across a latitudinal gradient, we asked: (1) Is there genetic variation within populations?

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 486-498, March 2026.Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

Shuitu Baochi Xuebao, 2017 为探讨草本植物根系对崩岗洪积扇土壤抗剪强度的影响，以巨菌草（Pennisetum sp.）和宽叶雀稗（Paspalum wettsteinii）为研究对象，采用WinRHIZO根系分析系统对根系特征进行定量分析，并采用原位剪切试验测定崩岗洪积扇各土层的抗剪强度。结果表明：（1）根系能够改善土壤的结构及水分状况。（2）2种草本植物根系均主要分布在0—5 cm土层，该层巨菌草根系各参数值是该草种根系均值的3.1~4.39倍，宽叶雀稗的则为2.23~2.57倍；随着土层深度的增加，巨菌草根系参数呈对数函数减小，

Catalysts for change: Museum gardens in a planetary emergency
PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 401-410, March 2026.Natural history museums are often seen as places with indoor galleries full of dry‐dusty specimens, usually of animals. But if they have gardens associated with them, museums can use living plants to create narratives that link outside spaces to inside galleries, bringing to life the challenges facing biodiversity.
