Highlights
● Salinity commonly hindered wheat germination, and using herb-derived carbon dots was an emerging approach to enhancing plant salt tolerance in agricultural production.
● Wolfberry-driven carbon dots (Wo-CDs) were synthesized and applied as a nano-primer to enhance wheat salt tolerance by maintaining reactive oxygen species levels through early oxidative stress conditioning.
● After 4 days of salt stress, Wo-CDs enhanced wheat jasmonic acid content to improve wheat salt tolerance and induced cytokinin biosynthesis to promote wheat germination.

摘要

全球约50%的耕地受到盐渍化威胁，严重制约小麦的发芽、生长。传统改良盐碱地方法成本高、周期长，亟需开发高效、低成本的作物耐盐性提升技术。植物纳米生物技术，特别是种子纳米引发，作为一种新兴策略，因其材料用量少、效果显著而备受关注。然而，利用经济易得的天然材料开发高效纳米引发剂及其作用机制尚不明确。该研究首次以成本低廉的原材料枸杞（成本约0.14元/克）为原料合成了枸杞源碳点（Wo-CDs），并使用其提高了盐胁迫下小麦的发芽率。研究人员进一步揭示了Wo-CDs通过激活早期氧化应激和调控关键激素代谢的双重机制。这种基于天然产物的纳米引发技术具有原料易得、成本低廉、环境友好的显著优势。
