“…It was described that the genes related to metabolism, proteins with binding function, development, and defense were differentially expressed when the soybean was infected with SMV [14]. Also, in previous studies, it was shown that at 10 days after infection with SMV, defense response, and signal transduction related genes in soybean were significantly induced, while energy and photosynthesis genes were repressed [16]. These studies are consistent with the results of our study.…”

“…Plant growth and defense are often negatively correlated because growth and development are affected by the infection of the pathogen [29]. The phenomenon of viral infection leading to dwarfing of plants is often observed [16,30,31]. In our experiments, soybean seedling growth and development was impaired after infection with SMV.…”

“…In the shade, plant growth is more severely damaged, with a reduction of 35.93% of plant height and 8.97% of stem diameter. Similarly, Díaz-Cruz et al studied soybean infected with SMV for 10 dpi and found that the average plant height was reduced to 26% as compared to the control (CK) [16]. This may be an important factor in the reduction of yield in the shade, that is, the growth and development of plants are seriously affected by the virus.…”

“…Previous studies have shown that larger changes in transcriptional levels occurred in soybeans infected SMV at 10 dpi [16]. Therefore, we collected the V2 leaves (the second trifoliolate leaf, newly grown) of soybean plants after treatment for 10 dpi.…”

“…In another study, Díaz-Cruz et al performed a transcriptome analysis of soybean V2 leaf infected with SMV at 10 dpi and found that differentially expressed genes (DEGs) were predominantly upregulated. The host defense responses and signal transduction were significantly induced, while energy metabolism and photosynthesis were repressed [16].…”

Shading in the intercropping system is a major abiotic factor which influences soybean growth and development, while soybean mosaic virus (SMV) is a biotic factor that limits the yield and quality of soybean. However, little is known about the defense response of soybean to SMV in the shade. Thus, in the current study, both intensity and quality (red:far-red, R:FR) of the light were changed to simulate the shaded environment and comparative transcriptome analysis was performed. Morphologically, plant growth was inhibited by SMV, which decreased 35.93% of plant height and 8.97% of stem diameter in the shade. A total of 3548 and 4319 differentially expressed genes (DEGs) were identified in soybean plants infected with SMV under normal light and in the shade. Enrichment analysis showed that the plant defense-related genes were upregulated under normal light but downregulated in the shade. Pathways that were repressed include plant-pathogen interaction, secondary metabolism, sugar metabolism, and vitamin metabolism. In addition, genes associated with signaling pathways such as salicylic acid (SA), jasmonic acid (JA), and ethylene (ETH) were also downregulated in the shade. A qRT-PCR assay of 15 DEGs was performed to confirm transcriptome results. According to our knowledge, this is the first report on soybean response to dual stress factors. These results provide insights into the molecular mechanisms in which soybean plants were infected with SMV in the shade.
