Yoruba Histories of Marriage and Belonging: Gender, Power and Innovation in Eighteenth‐Century West Africa

Gender &History, EarlyView.
ABSTRACT This article argues that marriage was central to historical change in the Yoruba‐speaking region of West Africa during the eighteenth century. It draws on ìtàn, a distinct oral source, to show that conjugality shaped Yoruba processes of urbanisation and political centralisation, gendered divisions of labour and social innovation and creativity.

The Long Arc of Forest Land Dispossession and Degradation—Firm and State Actions on Sámi Lands in the Wood‐Based Commodity Frontier in Northern Sweden, 1673–1955

Journal of Agrarian Change, EarlyView.
ABSTRACT This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood‐based commodity frontier at the expense of reindeer pastoralists among the ...

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

New Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

MtGRF8 interacts with MtSymCRK and prevents early bacteroid death during Medicago – Sinorhizobium symbiosis

New Phytologist, EarlyView.
MtSymCRK–MtGRF8‐14‐3‐3a, e, h and i functional model in R‐108 nodules. Summary In Medicago littoralis R‐108, Symbiotic CYSTEINE‐RICH RECEPTOR‐LIKE KINASE (MtSymCRK) is required to prevent defense reactions in symbiotic nodules during chronic infection.

EMERGÊNCIA E ESTABELECIMENTO DE PLÂNTULAS DE Guazuma ulmifolia LAM. EM FUNÇÃO DE DIFERENTES TRATAMENTOS PRÉ-GERMINATIVOS

Ciência Florestal, 2016
This study tested the influence of mechanical and thermal scarification methods on emergence and establishment of Guazuma ulmifolia seedlings. Seeds were subjected to pre-germination treatments of (1) mechanical scarification (sandpaper),

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Estudos sobre superação de dormência em sementes de Smilax japecanga Grisebach Studies of Smilax japecanga Grisebach seed dormancy breakage

Ciência e Agrotecnologia, 2003
A propagação sexuada de Smilax japecanga Grisebach é limitada em razão da dormência de suas sementes, as quais levam de 6 a 8 meses para germinar, dificultando, assim, a obtenção de mudas.

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, EarlyView.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Simple Mechanical Scarification Improves Seed Germination of Viola odorata ‘Empress Augusta’ When Combined with Cold Stratification

International Journal of Plant Biology
Viola odorata, commonly known as sweet violet, is valued for both its fragrance and medicinal properties. However, seeds of V. odorata exhibit non-deep physiological dormancy, resulting in poor and inconsistent germination.

Directed Evolution of Plant‐Associated Bacteria Enhances Plant Holobiont Stress Tolerance

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant stress responses are shaped by both the plant genome and its associated microbial communities, which together form the plant holobiont. Given the rapid adaptive potential of plant‐associated microbes, we hypothesised that directed evolution under selective pressure can accelerate the development of holobiont‐level stress tolerance ...
