It's quite common to coinfiltrate the Agrobacterium carrying the construct of interest together with another Agrobacterium carrying a silencing suppressor protein gene such as the one encoding the p19 protein from the plant pathogenic Tomato bushy stunt virus (TBSV), or the NSs protein from tomato spotted wilt virus (TSWV). TBSV was first discovered in 1935 in tomatoes and results in plants with stunted growth and deformed fruits. TSWV was discovered in tomatoes in Australia in 1915, and for many years was the only member of what is now known as genus Tospovirus, family Bunyaviridae.
