Implication

Transgenic study demonstrates increased seed yield and pathogen resistance in soybean lines, indicating a dual-benefit genetic target for crop enhancement.

Key Points

To assess the effects of overexpressing the terminal region of the anaphase-promoting complex subunit 7 (GmAPC7-CT) on yield performance and pathogen defense in soybean.
Engineered stable transgenic soybean lines overexpressing GmAPC7-CT, a 624-nucleotide sequence encoding a 207-amino acid protein with two tetratricopeptide repeat domains.
Evaluated developmental timelines, pod count, seed number, and seed weight across transgenic and control plants.
Assessed disease susceptibility by quantifying viral RNA load following soybean mosaic virus challenge and measuring the reproduction factor of the parasitic nematode Meloidogyne incognita.
Overexpression of GmAPC7-CT accelerated plant development, with the top three transgenic lines producing up to 43% more pods, 44% more seeds, and a 16% increase in seed weight.
Transgenic lines achieved up to a 70% reduction in susceptibility to both soybean mosaic virus and M. incognita, demonstrated by decreased viral RNA load and nematode reproduction factors.
