Abstract: | Background Anthracnose, caused by Colletotrichum dematium, is a serious threat to the production and quality of mulberry leaves in susceptible varieties. Control of the disease has
been a major problem in mulberry cultivation. Some strains of Burkholderia cepacia were reported to be useful antagonists of plant pests and could increase the yields of several crop plants. Although B. cepacia Lu10-1 is an endophytic bacterium obtained from mulberry leaves, it has not been deployed to control C. dematium infection in mulberry nor its colonization patterns in mulberry have been studied using GFP reporter or other reporters.
The present study sought to evaluate the antifungal and plant-growth-promoting properties of strain Lu10-1, to clarify its
specific localization within a mulberry plant, and to better understand its potential as a biocontrol and growth-promoting
agent. |
