喀斯特地质高背景区浅层裂隙土壤Cd剖面分布规律及其影响因素

open access: yesShuitu Baochi Xuebao
[目的] 研究浅层喀斯特裂隙土壤Cd的剖面分布规律,分析不同因素对裂隙中Cd分布的影响状况,为今后研究地下裂隙土壤中Cd的分布规律及Cd污染防治提供科学依据。[方法] 以黔西北典型地质高背景区小流域为研究对象,系统分析浅层裂隙土壤Cd的全量和形态,以及pH、有机质含量、阳离子交换量(CEC)、粒径和团聚体等5种土壤性质指标,通过方差和相关分析阐明裂隙剖面土壤Cd的分布规律及其影响因子。[结果] (1)裂隙土壤的理化因子对Cd分布影响显著;(2)裂隙土壤pH平均为6.70,Cd含量平均为2.99 mg ...

Neutral interactions among non‐native plants are common

open access: yesNew Phytologist, Volume 252, Issue 1, Page 292-309, October 2026.
Global distribution of studies and overall effect of co‐invasion for all metrics of non‐native plant performance combined. Summary Globalization has accelerated the establishment of non‐native plant species, increasing the prevalence of multispecies co‐invasions; yet interactions among co‐invaders remain poorly understood.

TipQuant: a robust algorithm for quantitative analysis of spatiotemporally dynamic activities in tip‐growing cells

open access: yesNew Phytologist, Volume 252, Issue 2, Page 926-935, October 2026.
Tip Quantification enables quantitative analyses over versatile selections of regions of interest. Summary Cell polarity and tip growth rely on the dynamic spatial organization of signaling and structural components. Quantitative characterization of these spatiotemporal dynamics is critical for understanding polarized cell growth, yet manual ...

AUXIN RESPONSE FACTORs: from transcription factors to auxin effectors

open access: yesNew Phytologist, Volume 252, Issue 2, Page 607-613, October 2026.
Molecular evolution of AUXIN RESPONSE FACTOR (ARF) effector function. Summary Signalling pathways have originated and diversified extensively during evolution. Using AUXIN RESPONSE FACTORs (ARFs) as a model, we examine how a plant signalling system evolved through the co‐option of pre‐existing transcriptional regulators, a principle well established in
