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...

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...

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...

Full-length transcriptome atlas of Panax vietnamensis var. fuscidiscus reveals novel genes and alternative splicing in tissue-specific biosynthesis of ocotillol-type saponins

Panax vietnamensis var. fuscidiscus is the only known Panax species that accumulates exceptionally high levels of ocotillol (OCT)-type ginsenosides, particularly majonoside R2. However, the molecular mechanisms underlying OCT-type ginsenoside biosynthesis remain largely uncharact...
