Dr. Miyaji Naomi, who is currently a researcher at Iwate Biotechnology Research Center) and Arjina Akter, who is a Ph.D. student in the same doctorate program with their colleagues, elucidated that the alterations to gene expression induced after infection of Japanese mustard spinach by white rust disease were different in disease-resistant cultivar and disease-susceptible cultivar.
resistance mechanism in Japanese mustard spinach through future research.
Plants grow, adapt and respond to the environment by controlling the expression of a variety of genes. To date, in a variety of plant species, it has become clear that resistance is induced in response to disease by the control of gene activity. between cultivars which are strongly resistant to white rust disease and cultivars susceptible to the disease .and white rust disease susceptible cultivar, and the gene expression before and after infection was analyzed. Genes were identified which increased/decreased in the level of expression as a result of infection by white rust disease fungus, and the commonality of these genes across the cultivars was investigated.
Next, by classification of known genes whose expression was altered by infection by the white rust disease fungus, the researchers were able to predict what kind of expression response was occurring in each variety. Many of the genes whose expression was altered in the resistant cultivar were classified into categories related to protective responses or categories related to salicylic acid.
