Few studies have been done on engineered antibodies for diagnosis of tospovirus infections. The present study was undertaken to develop a single-chain variable fragment (scFv) for specific diagnosis of infection by groundnut bud necrosis virus (GBNV), the most prevalent serogroup IV tospovirus in India. Heavy chain (372 nucleotide [nt]) and light chain (363 nt) variable region clones obtained from a hybridoma were used to make an scFv construct that expressed a ~29-kDa protein in E. coli. The scFv specifically detected GBNV in field samples of cowpea, groundnut, mung bean, and tomato, and it did not recognize watermelon bud necrosis virus, a close relative of GBNV belonging to tospovirus serogroup IV. This study for the first time demonstrated the application of a functional scFv against a serogroup-IV tospovirus. |
