SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.
Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...

CHINA’S LAND FINANCE AS ACTIVE MODE OF LAND DEVELOPMENT AND INFRASTRUCTURE DELIVERY: Reality, History and Prospects

open access: yesInternational Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.
Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Non‐Passerine Birds in Zoos: A Global Approach on Distribution Patterns of Threatened Birds in Zoological Institutions 动物园中非雀形目鸟类:全球动物机构中受威胁鸟类的分布模式研究

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.
Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...

DNA Barcoding Reveals Cryptic Diversity and Informs Conservation Priorities in Chinese Firmiana Species (Malvaceae) Using Genome Skimming Data DNA条形码揭示中国梧桐属 (锦葵科) 隐存多样性及保护优先级:来自基因组浅层测序数据的证据

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.
Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

霍乱弧菌新发菌株中vipAvipBclpV对T6SS转录调控

open access: yes, 2022
目的探索霍乱弧菌新发菌株H1的六型分泌系统(T6SS)存在的转录调控机制。方法本研究以转录组测序为基础,分析H1株分别由于vipA敲除(H1ΔvipA),vipB敲除(H1ΔvipB)和clpV敲除(H1ΔclpV)时T6SS基因簇的转录水平,并对其差异基因进行了基因本体论(GO)富集和京都基因与基因组百科全书(KEGG)富集。结果发现H1ΔvipA有22个差异基因(FDR<0.01,|log2FC|≥1),其中有18个属于T6SS基因簇;并且除vipA外,其转录水平均呈上升趋势 ...

Hydrocortisone Aceponate for Chronic Otitis: Long‐Term Efficacy

open access: yesVeterinary Dermatology, Volume 36, Issue 6, Page 870-878, December 2025.
Effective management of otitis externa (OE) requires addressing all contributing factors to prevent chronicity and recurrence. Evidence on the long‐term efficacy of topical corticosteroids in preventing recurrence and secondary infections remains limited. This retrospective noncontrolled study evaluated the efficacy of hydrocortisone aceponate (HCA) in
