Unlocking the genetic potential of sugarcane: gene discovery for molecular breeding

Sugarcane is a globally important crop for sugar production and bioenergy generation. However, its highly complex allopolyploid genome has greatly hindered conventional breeding, making cultivar development a lengthy and labor-intensive process that often requires more than a dec...

Nutrient cycling, environmental outcomes and mitigation pathways in sugarcane agroecosystems: A comparative synthesis of Brazil and Australia

Sugarcane is a major tropical crop with strong potential to support climate-smart agriculture through efficient nutrient cycling, improved nitrogen use efficiency, biofuel production and enhanced soil carbon dynamics. However, environmental outcomes vary substantially across prod...

NpSCI2A, a potato inhibitor I protein from a wild sugarcane relative, negatively regulates drought tolerance by targeting subtilases

Drought severely limits sugarcane productivity. The wild relative of sugarcane, Narenga porphyrocoma , is highly drought-tolerant and represents a valuable source of stress-resistance genes. We identified NpSCI2A , encoding a s potato inhibitor I that is significantly downregulat...

Integrative transcriptome and metabolome analyses to uncover rice panicle branch albinism

Chloroplast development is essential for photosynthesis and overall plant viability. While leaf and whole panicle albinism has been extensively studied as a model for chloroplast biogenesis, the genetic mechanisms underlying tissue-specific chloroplast development in reproductive...

SaMYC2 acts as a key transcriptional activator of terpenoid biosynthesis and is subject to feedback regulation by SaGNAT01 in Santalum album L.

Santalum album L. (sandalwood) is an economically important tree species valued for its heartwood essential oil, which is primarily composed of terpenoids. However, the transcriptional regulatory mechanisms governing terpenoid biosynthesis in sandalwood remain poorly understood....

The worth of diffusion-weighted imaging for quantifying liver iron concentration in transfusion-dependent thalassemia patients

Background Magnetic resonance imaging (MRI) is currently the primary method for evaluating liver iron concentration (LIC); however, most techniques necessitate intricate data post-processing. Consequently, the development of simple quantitative methods is highly desirable. Purpos...

Structural and metabolic basis of pepper (Capsicum spp.) fruit glossiness formation shown by microstructure and metabolomics analyses

Glossiness is a key appearance trait of pepper fruits, which directly affects their market price and consumer purchasing preference. Elucidating the structural and metabolic basis underlying glossiness formation is of great scientific and economic value. In this study, we quantit...

Straw Return and Tillage Management Strategies Reshape Soil Functionality and Enhance Maize Productivity

Long-term intensive maize cultivation under subtropical double-cropping systems has resulted in increased compaction and declining fertility. Although conservation tillage and straw return have been widely adopted to improve soil quality, their combined effects on soil physicoche...

Effects of Supplementation with Different Concentrations of Selenium on Fruiting Bodies and Substrate Microbial Community Dynamics in Pleurotus ostreatus Cultivation

To investigate the effects of substrate selenium on mushroom growth, nutritional quality, and associated microbial community structure, the thermo-tolerant Pleurotus ostreatus cultivar “Daye 39” was used as the experimental material. Sodium selenite was applied at gradient concen...

Integrated physiological, transcriptomic and metabolomic analyses characterize treatment-associated autumn shoot self-pruning and maturation in Wogan mandarin

Autumn shoot maturation is important for citrus canopy management and subsequent reproductive development. We compared five foliar treatments but interpret their effects as treatment-specific because the salts were not equimolar and KH₂PO₄ supplied both K and P. Water (CK), 0.3%...

A Gapless T2T Genome and Population-Scale Resequencing of Adzuki Bean Reveal Centromere Evolution and Accelerate Molecular Breeding

Abstract The adzuki bean (Vigna angularis) is an economically and nutritionally significant legume species. Using a multi-strategy sequencing approach, a gapless, telomere-to-telomere (T2T) genome assembly of an elite cultivar, Jihong 16 (JH16), was generated. The genome size was...

Differences in rhizosphere microbial communities between Fusarium wilt-resistant and susceptible watermelon cultivars

ABSTRACT To elucidate genotype-associated differences in rhizosphere microbial community assembly, this study compared the microbiomes of three Fusarium wilt-resistant and three susceptible watermelon cultivars using amplicon sequencing. Results revealed distinct bacterial and fu...
