Ants can nest in a wide variety of substracts. This paper shows Syagrus romanzoffiana seed utilization by ants in an Atlantic secondary forest. We report 29 seeds occupied by small-bodied ants, with 27 of them showing at least two ant development stages. Although a large number of seeds were sampled, a low level of ant occupation was observed.

Loss-of-function mutations induced by CRISPR-Cas9 in the TaGS3 gene homoeologs show non-additive dosage-dependent effects on grain size and weight and have potential utility for increasing grain yield in wheat. The grain size in cereals is one of the component traits contributing to yield. Previous studies showed that loss-of-function (LOF) mutations in GS3, encoding Gγ subunit of the multimeric G protein complex, increase grain size and weight in rice.

With climate change projections indicating an increase in the frequency of extreme heat events and irregular rainfall patterns globally, the threat to global food security looms large. Terminal heat stress, which occurs during the critical reproductive stage, significantly limits lentil productivity. Therefore, there is an urgent need to improve lentil's resilience to heat stress to sustain production.

The expansion of irrigated agriculture in semi-arid regions exacerbates the degradation of wetland ecosystems. Precision water recharge can facilitate near-natural restoration of degraded wetlands by alleviating the conflict between wetlands and agricultural water use. However, although the ecological significance of precision water recharge as a nature-based solution for restoring wetland vegetation has been widely acknowledged, the mechanisms driving its role in spikelet development and seed growth in Carex schmidtii Meinsh.

The reconstruction of large-sized soft tissue defects remains a substantial clinical challenge, with adipose tissue engineering emerging as a promising solution. The acellular dermal matrix (ADM), known for its intricate spatial arrangement and active cytokine involvement, is widely employed as a scaffold in soft tissue engineering. Since ADM shares high similarity with decellularized adipose matrix, it holds potential as a substitute for adipose tissue.

High-oleic peanuts are increasingly valued in agricultural production and consumer markets. Nevertheless, limited genomic information hinders the integration of genetic analyses and modern breeding strategies. This study details a chromosome-level genome assembly of Kaixuan 016, a high-oleic peanut variety developed through gamma-radiation-assisted breeding, exhibiting enhanced agronomic traits.
