Rapid screening of pest resistance genes in maize using a sugarcane mosaic virus vector

Abstract: Spodoptera frugiperda (fall armyworm) is a notorious pest that threatens maize production world-wide. Current control measures involve the use of chemical insecticides and transgenic maize expressing Bacillus thuringiensis (Bt) toxins. Although several additional transgenes have confirmed insecticidal activity in other plants, limited research has been conducted in maize, at least partially due to the technical difficulty of maize transformation. Here, we describe implementation of a sugarcane mosaic virus (SC… Show more

“…The high reproductive rate of this aphid makes in the main pest of sorghum; because it leads to a reduction in productivity caused by the ov of secreted honeydew, which reduces photosynthetic activity, especially by the accumulation of sooty mold on the leaves (Bowling et al, 2016). In addition, the aphid is also a vector of viruses such as: millet red leaf virus (Blackman and Eastop, 1994;Paray et al, 2011), sugarcane yellow leaf virus in sorghum and sugarcane (Schenck and Lehrer, 2000;Boukari et al, 2021) and sugarcane mosaic virus in sorghum (Setokuchi and Muta, 1993;Chung et al, 2021).…”

“…Towards this goal, a modified sugarcane mosaic virus (SCMV) vector was developed in maize for the transient over-expression of defense associated proteins and functional assessment in planta [88]. Potential applications include the expression of non-native genes to explore the production of novel defense chemistries.…”

“…For potato (Solanum tuberosum) root delivery, Bacillus subtilis were recently engineered to secrete StPep1 which significantly reduced galling by the plant pathogenic nematode, Meloidogyne chitwoodi [93 • ]. Similarly, transient expression of ZmPep1 and ZmPep3 via a sugarcane mosaic virus vector activated maize pathways for specialized metabolism and strongly induced resistance against diverse insects [88].…”
