Effects of land use pattern on invasive plant diversity in Guinean savanna ecosystems of Togodo protected area, Togo [PDF]
, 2018 Tropical natural ecosystems host a very diverse flora and fauna and are key ecosystems for global climate and biogeochemical regulation. Unfortunately, in West African landscapes, large areas of savanna and forest have been progressively replaced or ...

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa
Advanced Science, EarlyView.This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

ACTAE regional project Accompanying the Agro-ecological Transition in Southeast Asia 2015 - 2019 Final report [PDF]
, 2019 L'agro-écologie répond à de nombreuses définitions relevant à la fois de dimensions scientifiques, environnementales et sociétales. Selon la littérature, les techniques qui lui sont attribuées concernent l'agriculture de conservation, l'agroforesterie ...

Advanced Science, EarlyView.Nap1l4a is required in erythropoiesis and hypoxia responses via physical interaction with Klf1 and Scl to recruit the histone variant H2A.Z. This facilitates its associated cis‐regulatory element (CRE) remodeling and the consequent chromatin assembly, and activates the transcription of erythroid lineage‐specific genes.

Advanced Science, EarlyView.A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

Advanced Science, EarlyView.BCR sequencing and subclone analysis correlated immunoglobulin (Ig) chain loss in dysfunctional hybridomas with disrupted monoclonal antibody homeostasis. Proteomics‐guided CRISPR/Cas9 editing revealed that the unfolded protein response (UPR) regulates aberrant Ig synthesis.

Economics of soil and water conservation [PDF]
, 2003 The Ethiopian highlands, inhabited by the vast majority of the Ethiopian human and livestock populations, are under continuous threat from soil erosion. Land degradation induced by soil erosion is considered to be among the major factors responsible for ...

, 2021 La dégradation des terres liée à l'intensification agricole, principalement due à la baisse de la fertilité des sols et à l'érosion, est devenue une problématique majeure en Nouvelle-Calédonie. Le contexte insulaire et les spécificités pédoclimatiques rendent en outre les enjeux d'autosuffisance alimentaire, de préservation des agroécosystèmes et de la

Advanced Science, EarlyView.By integrating biomechanical and epigenetic cues, the evolutionarily conserved TPM1 super‐enhancer drives myogenesis via TEAD4‐mediated chromatin looping. This mechanism produces species‐specific outputs (linear TPM1 mRNA in mice and CircTPM1 in bovine) that activate PI3K/AKT mechanotransduction and the MYH10/MYL3 axis to execute cytoskeletal ...
