CiPLDδ2 determines postharvest storage stability of pecan by regulating membrane lipid degradation and the antioxidant system

The high oil content, combined with unsaturation, of pecan ( Carya illinoinensis ) kernels renders them prone to oxidation as well as hydrolysis during storage, thereby causing quality deterioration. Previous evidence indicates that Phospholipase D δ2 in C. illinoinensis ( CiPLDδ...

Grassland soil bulk density decreases under grazing exclusion and responds asymmetrically to altered precipitation

Soil structure is a key determinant of grassland health and functioning, with bulk density serving as a widely used proxy. Grazing exclusion is a common restoration practice that often reduces soil bulk density in grasslands by restoring plant productivity and removing livestock...

Aridity regulates scale-dependent effects of multiple resource additions on productivity stability in Eurasian grasslands

Increasing the supply of multiple limiting resources generally reduces biodiversity and community stability in grasslands. Aridity is known to modify biodiversity-stability relationships, yet it remains unclear whether the effects of multiple resource supply on biodiversity and s...

The ABCG transporter OsPDR17 mediates transport of 5,10‐diketo‐casbene and enhances disease resistance in rice

Compound 5,10-diketo-casbene (DKC) is a key macrocyclic diterpenoid phytoalexin contributing to rice resistance against bacterial blight. Although its activity depends on transmembrane transport, the transporter of DKC remains unknown. Using transcriptome profiling and a yeast ex...

Effects of Ammonium-to-Nitrate Ratio and 6-BA Co-Application on the Growth and Development of Blackberry

Cytokinin and nitrogen synergistically regulate plant physiological metabolism and developmental processes; however, their combined application on the growth, yield and fruit quality of blackberry remains unreported. This study aimed to investigate the effects of different ammoni...

Aridity drives carbon redistribution among biomass, soil organic and inorganic pools following forestation

Forestation is widely promoted as a nature-based solution for climate change mitigation through carbon sequestration, yet its net carbon outcomes remain uncertain because water limitation may regulate both total carbon storage and carbon allocation among ecosystem pools. Here, we...

Toward high‐quality genomes: Standards, challenges, and strategies for assembly and annotation

Abstract Genomes provide the fundamental basis for understanding biological systems. Owing to rapid advances in sequencing technologies and assembly methods, the number of sequenced genomes has increased substantially. A high‐quality genome should have high continuity, completene...

Physiological Responses and Absorption Removal Effects of Three Floating Macrophytes to Polystyrene Nanoplastics Pollution

Microplastics exert toxic effects on aquatic plants, thereby impacting ecosystem functions and services. Currently, research on the effects of nanoplastics on aquatic plants has mainly focused on algae, while floating macrophytes have received less attention. To investigate the p...

Creation of rosemary germplasm resources with high glandular trichome density and elevated levels of volatile and non-volatile functional components

Rosemary originates in the Mediterranean region and is a traditional medicinal and aromatic plant. It contains a variety of bioactive components, including both volatile and non-volatile, and exhibits properties such as antioxidant, anti-inflammatory, anti-tumor, anti-fungal, and...

An ABA /auxin regulatory module controlled by nitrogen governs symbiotic organogenesis in the bryophyte species Ricciocarpos natans

Summary During the terrestrialization of plants c. 470 Ma, overcoming nitrogen limitation was a major evolutionary challenge. While nonvascular plants may acquire nitrogen through rhizoids and surface diffusion, symbiotic interactions likely provide an important strategy to overc...

Global rice methane emissions tripled over six decades amid declining emission intensity

Abstract Rice paddies are among the largest anthropogenic sources of methane (CH4), yet substantial uncertainties persist in the long-term magnitude and spatiotemporal dynamics of the emissions. Here we show a spatially explicit global estimate of rice CH4 emissions from 1961 to...

Biocontrol efficacy and possible mechanism of a broad-spectrum antagonistic yeast, Pichia kluyveri NY23, screened from peach fruit via microbiome analysis

Fungus-induced postharvest diseases are the leading causes of fruit loss and waste. Meanwhile, some pathogens also produce mycotoxins, posing a grave risk to public health. Fruit epicarps harbor abundant microbiota, and shifts in these communities are tightly coupled with the occ...

Modular Sensory and Morphological Adaptations Underlying Fresh-Fruit Exploitation in Drosophilid Flies

(1) Background: Drosophilid flies oviposit in damaged or fermenting substrates, whereas D. suzukii prefers to lay eggs in ripening fruits. This ecological shift requires females to recognize fruit-stage cues while overcoming the mechanical barrier imposed by fresh-fruit surfaces....

Population Structure, Morphological Integration and Regional Differentiation of Dactylorhiza fuchsii (Druce) Soó in the Central Highlands of Kazakhstan

Dactylorhiza fuchsii (Druce) Soó is an ecologically sensitive terrestrial orchid and an important indicator of habitat condition, yet its population structure and morphological variability remain poorly studied in the Central Kazakh Uplands. This study evaluated the population si...

Plastome convergence across endoparasitic plant lineages: genome reduction, high AT bias, elevated substitution rates, and functional persistence in Mitrastemon yamamotoi

In heterotrophic plants, the loss of photosynthesis is often associated with plastid genome (ptDNA) reduction, although the extent of genome decay varies widely among lineages and may culminate in complete genome loss. Of the multiple transitions to heterotrophy among angiosperms...

Species Diversity and Elevational Patterns of Saxicolous Lichens in the Eastern Pamir Plateau, China

Saxicolous lichens are crucial elements of alpine ecosystems and are involved in soil formation, rock weathering, nutrient cycling, and environmental monitoring. However, little is known about their distribution patterns and diversity on the eastern Pamir Plateau of China. This s...
