Characterization of the MeWRKY12–MeSSIV Regulatory Module and MeWRKY12 Promoter Activity in Cassava

Background: Soluble starch synthases are essential for starch formation, but their transcriptional regulation remains poorly understood in cassava. Starch synthase IV (SSIV) is an important enzyme in starch biosynthesis, and this study aimed to investigate the transcriptional reg...

Balancing Prolificacy and Lamb Meat Production: Links Among Litter Size, Prenatal Development, Carcass Traits, and Meat Quality in Sheep

Prolificacy can increase lamb output per ewe, but its productive value depends on the survival, growth, and carcass performance of each additional lamb. This review examines the pathway from genetic control of ovulation to realized litter size, prenatal development, neonatal viab...

Optimized Callus Subculture and Multi-Omics Analysis Reveal Somatic Embryogenesis Bottlenecks in the Cold-Resistant Rubber Tree Clone GT1

The rubber tree (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.) is the predominant global source of natural rubber; however, its cultivation is largely confined to tropical regions due to chilling sensitivity. Although the chilling-tolerant clone GT1 holds considerable promi...

Coffee Anthracnose-Associated Fungi from Wanning, Hainan: Fungicide Sensitivity and Broad-Spectrum Antagonism by Mangrove-Derived Streptomyces sp. CD103

Fungi associated with coffee leaf lesions provide a diverse target panel for evaluating fungicide sensitivity and microbial antagonism. This study evaluated the antagonistic spectrum of mangrove-derived Streptomyces sp. CD103 and fungicide sensitivity in selected lesion-associate...

How climatic, edaphic, and biotic drivers collectively govern large-scale grassland biomass allocation

Abstract The pattern of vegetation biomass allocation is a key mechanism for understanding the carbon sequestration function of grassland ecosystems and their responses to global change. By integrating multi-scale observations and global datasets, this study applied extreme gradi...

Control efficacy of fermentation extracts from Streptomyces violaceusniger 5–6 against postharvest mango anthracnose and associated host defense responses

Mango anthracnose caused by Colletotrichum gloeosporioides is a major postharvest disease. This study evaluated the control efficacy of fermentation extracts derived from Streptomyces violaceusniger 5–6 and investigated their associated antifungal and host-response mechanisms. At...

MdKIM1-MdMYB306 enhances apple resistance to Cytospora mali via brassinosteroid biosynthesis under sufficient potassium status

Potassium (K) supplementation enhances apple (Malus ×domestica) resistance to Cytospora mali, thereby reducing apple Cytospora canker occurrence in the field. Nevertheless, the molecular mechanisms underlying this K-enhanced resistance remain largely unelucidated. Here, we found...

Establishment of a Near-Infrared Spectroscopy-Based Screening Framework for Key Quality Indicators of Cassava Varieties

Cassava is the sixth most important food crop globally, valued for its high starch accumulation in tuberous roots, which supports diverse applications in food processing and industrial production. Quality evaluation is vital for its utilization, yet rapid and efficient assessment...

Rhizosphere Microbiome Characteristics of Grafted Watermelon and Own-Rooted Watermelon Under Continuous Cropping Soil Conditions

Continuous cropping in tropical protected cultivation can impair soil health and increase the risk of soil-borne disease. We conducted a single-season field comparison in Hainan (October 2025–February 2026) to characterize the performance and rhizosphere microbial profiles of the...

Substrate Recognition Analysis in an Ethyl Carbamate-Hydrolyzing Esterase and Semi-Rational Baijiu Flavor Preservation

Ethyl carbamate (EC) is a widely recognized carcinogen present in fermented foods, and enzymatic degradation is a safe and effective strategy for its reduction. An EC-degrading esterase derived from Acinetobacter calcoaceticus (AcECH) was previously identified. However, volatile...

Effects of Dietary Alpinia officinarum Extract on Performance, Immunity, Microbiota, and Aeromonas hydrophila Resistance in Red Claw Crayfish

Plant extracts contain multiple bioactive compounds and have been extensively investigated as alternatives to antibiotic-based feed additives in aquaculture. The present study was designed to evaluate the effects of dietary supplementation with galangal (Alpinia officinarum) extr...

Integrated Transcriptome and WGCNA Analyses Reveal Candidate Regulatory Networks Associated with Shell Hardening in Macadamia integrifolia

To characterize the transcriptomic dynamics underlying shell hardening in Macadamia integrifolia, RNA sequencing was performed on pericarp and shell tissues collected at three key developmental stages. A total of 18 libraries were generated, yielding 125.19 Gb of clean data. Gene...

Assessing Cultivated Land Abandonment in Hainan Island: Spatio-Temporal Differentiation and Driving Mechanism

Cultivated land abandonment poses a growing threat to regional food security and sustainable land resource allocation in tropical island regions, making the accurate identification of its spatio-temporal characteristics and driving mechanisms an urgent research priority. This stu...
