Special Issue Information

Dear Colleagues,

Oilseed crops, including rapeseed (canola), soybean, sunflower, peanut, etc., serve as a primary source of edible oils in many regions. With the growing global demand for vegetable oils and the need for sustainable agricultural practices, the primary objectives of genetic improvement in oilseed crops are to enhance yield potential, improve oil content, modify oil composition, increase resistance to biotic and abiotic stresses, and adapt varieties to diverse environmental conditions. Modern biotechnology tools, particularly genetic engineering, genome editing techniques, and GWAS, have revolutionized the field of crop improvement. These technologies allow scientists to precisely modify specific genes associated with important agronomic and quality traits. In addition, genetic improvement efforts also focus on genetic resource screening, evaluation, and utilization. We developed this Special Issue to provide a collection of the current and new progress in oilseed crop research.

Antimony (Sb), a toxic metalloid, inhibits plant growth and threatens human health. Yellow Stripe-Like (YSL) proteins play crucial roles in metal ion transport and cellular homeostasis. While the OPT gene family has been characterized in some species, its genome-wide organization and functional involvement in Sb stress response remain unexplored in Brassica juncea. Here, we identified 47 high-confidence BjOPT genes and combined transcriptomic approaches to elucidate their regulatory roles under Sb stress. Phylogenetic tree, conserved motifs, and gene structure analyses consistently distinguished the BjOPT and BjYSL subfamilies. Comparative and collinearity analyses indicated that OPT genes in Brassica species (including B. rapa, B. nigra, and B. juncea) expanded independently of whole-genome triplication events. Transcriptomic profiling revealed significant enrichment of differentially expressed genes (DEGs) related to key biological processes (oxidative and toxic stress response, metal ion transport, and auxin efflux) and pathways (glutathione metabolism, MAPK signaling, and phytohormone transduction), highlighting their roles in Sb detoxification and tolerance. Notably, three BjYSL3 (BjA10.YSL3, BjB02.YSL3, and BjB05.YSL3) genes exhibited strong up-regulation under Sb stress. Heterologous expression in yeast demonstrated that both BjA10.YSL3 and BjB02.YSL3 enhance Sb tolerance, suggesting their potential role in transporting Sb–nicotianamine (NA) or phytosiderophore (PS) complexes. These findings advance our understanding of Sb tolerance mechanisms and provide a basis for developing metal-resistant crops and phytoremediation strategies. Full article
