Scientists Analyze Gene Expression in RBSDV-infected Maize
March 16, 2012| |
Maize rough dwarf disease is one of the major viral diseases of maize in China. It is caused by rice black-streaked dwarf virus (RBSDV). Previous studies have shown that viral infection of plants might cause distinct disease symptoms through inhibition or activation of host gene transcription. Thus, China Agricultural University scientist Meng-Ao Jia and colleagues analyzed the gene expression profile of maize infected by RBSDV using specialized gene chips to reveal possible expression changes linked to symptom development.
Results of the analysis showed the occurrence of alterations in expression of different resistance-related genes as well as cell wall- and development-related genes. These findings could be used to look for new ways to protect cereal crops against viruses, and reveal the molecular mechanisms involved in the development of specific symptoms in rough dwarf-related diseases.
