Incidence of epigeal nest-building termites in Brachiaria pastures in the Cerrado - doi: 10.4025/actasciagron.v33i1.7075

open access: yesActa Scientiarum. Agronomy, 2011
This study aimed to determine the number of termite epigeal nests and estimate the soil turning capacity of termites in cultivated pasture environments and in a native vegetation area.

WTAP Transcriptional Suppression by KLF9 Drives Osteoclastogenesis via M6A‐Mediated Regulation of CSF1R Signaling in Estrogen‐Deficient Osteoporosis

open access: yesAdvanced Science, EarlyView.
Scheme of the KLF9/WTAP/YTHDF2/m6A/CSF1R regulatory axis in osteoclastogenesis and estrogen‐deficient osteoporosis. WTAP‐mediated m6A modification of Csf1r mRNA governs osteoclastogenesis via a YTHDF2‐mediated pathway. Pathological upregulation of KLF9 drives Wtap transcription, leading to increased m6A deposition on the 3’‐UTR of Csf1r mRNA.

Annual carbon balance of an intensively grazed pasture: magnitude and controls [PDF]

open access: yes, 2009
Soil carbon (C) is important because even small changes in soil C can affect atmospheric concentrations of CO₂, which in turn can influence global climate.

AARS1‐Mediated H3K27 Lactylation Rewires Glycolysis to Sustain Aggressive and Recurrent Bladder Cancer

open access: yesAdvanced Science, EarlyView.
AARS1 drives PI3K–AKT–mTOR‐dependent glycolysis in bladder cancer, promoting lactate accumulation, increased lactylation, H3K27la enrichment at the HK2 promoter, and HK2 transcription. HK2 reinforces glycolysis, sustaining a metabolic–epigenetic program associated with tumor progression, recurrence, and metastasis.

Transposable Element Dynamics Drive the Genomic Evolution and Phenotypic Diversification of Allotetraploid Common Carp

open access: yesAdvanced Science, EarlyView.
By integrating 516 whole‐genome resequencing datasets and 236 transcriptomes of allotetraploid common carp, this study establishes the first population‐scale atlas of transposable element (TE) variation in teleost species. TE bursts, relaxed purifying selection, and lineage‐specific loss of ancient insertions shape genome evolution and phenotypic ...

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

open access: yesAdvanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.

Horse Welfare and Natural Values on Semi-Natural and Extensive Pastures in Finland: Synergies and Trade-Offs

open access: yesLand, 2017
In several regions in Europe, the horse is becoming a common grazer on semi-natural and cultivated grasslands, though the pasturing benefits for animals and biodiversity alike are not universally appreciated.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Evaluating the mineral nutrient status of fresh pasture herbage using laser-induced breakdown spectroscopy [PDF]

open access: yes, 2014
Comprehensive determination of the mineral nutrient status of pasture or horticultural crops currently requires leaf or herbage samples to be harvested and taken to a laboratory for analysis, which is both labour-intensive and time-consuming.
