Narrowing the search for greenbug resistance in wheat
The study identified 692 differentially expressed genes between resistant and susceptible groups. Among them, 122 genes were known to be associated with biotic stress responses such as insect feeding, he said.
The resistant group activated more genes related to early defense signaling, which minimizes the feeding damage, Reddy said. In the susceptible lines, more genes related to cell wall stability and basal defense were activated, indicating the greenbugs had caused significant damage during feeding.
Combining this new knowledge with other approaches of gene identification will help the researchers identify and confirm gene-specific markers for greenbug resistance, and then this technology can be utilized by wheat geneticists and breeders, he said.
