Advances in studies on the responses of plant root morphology and anatomical structure to waterlogging stress(植物根系形态和解剖结构响应渍水胁迫的研究进展)

open access: yes浙江大学学报. 农业与生命科学版
Waterlogging is a common abiotic stress constraining crop production globally. Under waterlogging stress, the content of O2 in the soil reduces dramatically, causing hypoxic or even anoxic conditions to plants.

Politicizing Disaster: Examining the Effect of Ideology on Media Framing of the Itaewon Crowd Crush Disaster in South Korea

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.
ABSTRACT Using the Itaewon Crowd Crush Disaster as a case study of an emerging large‐scale disaster, we examine how ideology is related to media framing. Emerging large‐scale disasters and crowd crushes are useful for examining the role of ideology in media framing because they do not have the same ingrained ideological biases as other disasters ...

Sign Language as “Mother Tongue Orphan”: A Challenge to Raciolinguistic Multiculturalism in Singapore

open access: yesAmerican Anthropologist, Volume 127, Issue 3, Page 517-528, September 2025.
ABSTRACT This article examines the contested status of “sign language” in Singapore by exploring deaf people's experiences of the “Mother Tongues”—the state's designation for the official languages of Mandarin, Malay, and Tamil—with a particular focus on the relationships that deaf Chinese Singaporeans have with Mandarin.

Uncovering the Nanozostera japonica species complex suggests cryptic speciation and underestimated seagrass diversity

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2086-2097, September 2025.
Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.

滴喷灌施肥方式对土壤养分空间分异及茶苗根系生长的影响

open access: yesShuitu Baochi Xuebao, 2022
探究滴灌和喷灌对土壤理化和生物学性状及茶苗根系生长的影响,为科学灌溉施肥提供理论依据。土壤培养设置土施(SA)、喷施(FA)和滴施(DA)3种施肥方式,15,30,45,60天后,选取培养钵表土中心点为参照,根据距中心点水平和垂直方向距离差异,将培养土壤划分3个空间区域,观测pH、电导率、养分和生物学性质;茶树盆栽试验设置2个氮水平和土施、喷施、滴施3种施肥方式共6个处理,观测茶苗根系生长和形态。土培试验结果表明,FA与SA处理不同空间土壤区域无明显差异,而DA与FA之间差异明显,60天后离中心点水平5

Altered nutrient cycling functionality in seagrass meadows under a simulated future marine heatwave event

open access: yesNew Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.
Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Simple sequence repeats and their expansions: role in plant development, environmental response and adaptation

open access: yesNew Phytologist, Volume 247, Issue 2, Page 504-517, July 2025.
Summary Repetitive DNA is a feature of all organisms, ranging from archaea and plants to humans. DNA repeats can be seen both in coding and in noncoding regions of the genome. Due to the recurring nature of the sequences, simple DNA repeats tend to be more prone to errors during replication and repair, resulting in variability in their unit length ...

Investigating the mechanisms linking revenue recycling to increased political acceptability of carbon pricing

open access: yesReview of Policy Research, Volume 42, Issue 4, Page 1050-1075, July 2025.
Abstract This paper analyzes the causal relationship between the carbon tax's revenue recycling measures and political acceptability. The Irish carbon tax reform of 2019 forms the basis of the study. The findings are based on deductive content analysis and semi‐structured, elite interviews with key politicians, climate policy advisors, and other ...
