Implication

Experimental study demonstrates that APC7 overexpression enhances growth and viral resistance in Arabidopsis thaliana, suggesting a mechanism to overcome growth-defense trade-offs.

Key Points

To investigate the functional role of the AtAPC7 gene and its C-terminal truncation in regulating plant growth, photosynthetic capacity, and resistance to viral pathogens.
Generated transgenic Arabidopsis thaliana plants overexpressing full-length AtAPC7 (APC7 OE) and its C-terminal fragment (APC7-CT OE).
Characterized phenotypic, physiological, and molecular alterations, including vegetative organ growth, flowering time, photosynthetic efficiency, CO2 assimilation, and seed yield relative to Col-0 controls.
Assessed plant susceptibility following challenge with both RNA and DNA viruses.
APC7 OE plants exhibited enhanced vegetative organ growth, earlier flowering, increased photosynthetic efficiency, higher CO2 assimilation, and improved biomass and seed yield relative to Col-0 controls.
APC7-CT OE plants demonstrated significantly reduced susceptibility to both RNA and DNA viruses and maintained improved plant growth compared to controls, mitigating typical growth-defense trade-offs.
