The extent of viral infection significantly shapes disease susceptibility. Yellow mosaic disease induced by the begomovirus pathogen mungbean yellow mosaic India virus (MYMIV), revealed varying infection levels in both compatible and incompatible interactions across three distinct species such black gram, green gram, and rice bean. Differential gene expression analysis focused on MYMIV coat protein () and replication protein () highlighted elevated expression in the susceptible green gram genotype SML1082 compared to the black gram genotype KUG253. Conversely, showed higher expression in black gram than green gram, illustrating complex infection mechanisms among compatible MYMIV- interactions. A novel infection pathway, termed "Lack of Efficient Assembly (LEA)," has been hypothesized in MYMIV- interactions. Additionally, a whitefly-mediated artificial transmission model for begomoviruses, named Transparent Airflow Stress-free Container (TASC), has been designed and demonstrated for the efficient transmission of MYMIV. This study enhances the understanding of begomovirus infection dynamics in diverse species, offering insights into disease management strategies.

病毒感染的程度显著影响疾病易感性。由双生病毒病原体绿豆黄花叶印度病毒（MYMIV）引起的黄花叶病，在黑豆、绿豆和饭豆这三种不同物种的亲和与非亲和互作中均表现出不同的感染水平。针对MYMIV外壳蛋白（）和复制蛋白（）的差异基因表达分析表明，与黑豆基因型KUG253相比，易感绿豆基因型SML1082中的表达升高。相反，在黑豆中的表达高于绿豆，这说明了亲和性MYMIV互作之间复杂的感染机制。在MYMIV互作中已假设了一种新的感染途径，称为“缺乏有效组装（LEA）”。此外，还设计并展示了一种用于双生病毒的粉虱介导人工传播模型，名为透明气流无应激容器（TASC），用于高效传播MYMIV。本研究增进了对双生病毒在不同物种中感染动态的理解，为疾病管理策略提供了见解。
