The uptake, translocation, and subcellular distribution of oxathiapiprolin and famoxadone in tomato plants were investigated using hydroponic experiments. Oxathiapiprolin and famoxadone mainly accumulated in the tomato roots with limited translocation capacity from the roots to the upper part. The root absorption and inhibitor results noted the dominance of the apoplastic and symplastic pathways in the oxathiapiprolin and famoxadone uptake by the tomato roots, respectively. Furthermore, the uptake process for the two fungicides followed passive and aquaporin-dependent transport. Insoluble cell components (cell organelles and walls) were the dominant storage compartments for oxathiapiprolin and famoxadone. In the protoplast, oxathiapiprolin in the soluble fraction had a higher proportion than that of famoxadone. Finally, the uptake and distribution of the two fungicides by the tomato plants was accurately predicted using a partition-limited model. Thus, this study provides an in-depth understanding of the transfer of oxathiapiprolin and famoxadone from the environment to tomato plants.

番茄植株 (Lycopersicon esculentum Miller) 中氧噻唑啉和法莫沙酮的摄取、易位和亚细胞分布
使用水培实验研究了氧噻唑啉和恶唑沙酮在番茄植株中的摄取、易位和亚细胞分布。氧噻唑啉和法莫沙酮主要在番茄根部积累，从根部到上部的转运能力有限。根吸收和抑制剂结果表明，番茄根吸收氧噻唑啉和法莫沙酮的质外体和共质途径分别占优势。此外，两种杀菌剂的吸收过程遵循被动和水通道蛋白依赖性转运。不溶性细胞成分（细胞器和细胞壁）是氧噻唑啉和法莫沙酮的主要储存室。在原生质体中，可溶性部分中奥沙噻脯林的比例高于法莫沙酮。最后，使用分区限制模型准确预测了番茄植物对两种杀菌剂的吸收和分布。因此，这项研究提供了对氧噻唑啉和恶沙酮从环境转移到番茄植物的深入了解。
