The IKU2/RLK7–MAPK–MINI3 signaling module controls endosperm cellularization timing to determine seed size in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The phosphorylation status of the WRKY transcription factor WRKY10/MINI3, controls the timing of endosperm cellularization in Arabiopsis, thus regulating final seed size, offering a molecular understanding that could inform future agricultural breeding strategies. ABSTRACT Seed size is a critical factor in determining crop yield.

Local Elites in Chile's Pisco Valley: Dispossession, Legal Mobilisation and Intertwined Citizenship

Journal of Agrarian Change, EarlyView.
ABSTRACT In countries in the Global South, citizenship is often closely tied to access to water and land ownership. In Latin America, the literature has primarily explored social mobilisation and identity reconfiguration in response to development‐driven processes of land and water dispossession affecting peasants, rural and Indigenous communities ...

Patrones de variación espacio-temporal de grupos funcionales alimentarios en arroyos serranos de Córdoba, Argentina

Ecología Austral, 2010
La estructura trófica de las comunidades bentónicas está condicionada por la disponibilidad de recursos alimenticios, los cuales a su vez varían en función del tamaño del arroyo, la cobertura y el tipo de sustrato.

Heat stress induces organelle alterations in Macrocystis pyrifera gametophytes

Journal of Phycology, EarlyView.
Abstract Kelp, brown macroalgae in the order Laminariales, provide ecosystem services vital to ocean biodiversity. However, kelp forests worldwide are declining due to abiotic stressors such as ocean warming. In this study, we present results from high‐resolution confocal microscopy and in vivo imaging system imaging using protocols developed to ...

What Is the Ideal Time to Provide Corrective Feedback? An Approximate Replication of Li, Zhu, and Ellis (2016)

Language Learning, EarlyView.
Abstract This replication study examines feedback timing in vocational language learners and verifies the hypothesis that the advantage of immediate over delayed feedback found in the original study (Li, Zhu, & Ellis, 2016) is due to practice opportunities in immediate feedback.

Periodontitis‐Associated Bacteria and Their Connection to Proinflammatory Biomarkers in Periodontal Pockets: A Clinical Microbiological Study

Oral Diseases, EarlyView.
ABSTRACT Background This study examines the relationship between the microbial load of selected periodontitis‐associated bacteria (PAB) and proinflammatory biomarkers in gingival crevicular fluid (GCF) from patients with periodontitis. Methods GCF and subgingival biofilm samples were collected from the deepest periodontal pocket of each quadrant of 515
