Interpretive Summary:

Technical Abstract: Plants have developed several layers of immunity in order to defend against unrelenting pathogenic attacks. One of these layers is resistance genes. NLR genes are a type of resistance gene, and are involved in pathogen recognition and activation of a hypersensitive response. Genetic data and inferences about NLR proteins have been used to find six predicted NLR proteins in the locus for rhizomania resistance in sugar beets. These predicted proteins were studied using sequence alignment and phylogenetic tree building programs, with the goal of learning more about the evolution and diversity of NLR proteins and how they are involved in the plant’s immune response. The results of the study indicated that the predicted genes were likely fragmented parts of whole genes. The available data was used to generate hypotheses about the genes and begin improving gene models.
