Labs abroadThe Utrecht scientists , including the shared - first authors Pim Goossens and Jelle Spooren , obtain that especially the constitution of bacteria on the industrial plant ’s leave changes after infection with sericeous mildew , a fungus - like micro - being . Goossens : " On the above - footing parts of the plant , we found that a very belittled number of bacterial specie was extremely abundant on infected plants and that these bacteria limit the growth of the pathogen on the plant life . “The research worker then liken the bacterial residential area on infect plants in Utrecht with those in laboratories afield . " Hundreds of thousands of unlike species of bacteria exist worldwide " , Goossens says . " But to our great surprisal , we found on the nose the same dominant bacterium on taint plants from research laboratory in Germany and England . "
Protective legacyPlants appear to attract these bacteria from the soil , after which the bacteria accumulate on the leaves , where they can protect the plant . Berendsen : " After the plant die , those bacteria again survive in the land . A new contemporaries of plants directly benefits from that protective bequest as the unspoiled bacterium right away colonize the young plant . "
craw make their own disease - resistant soilThe scientist are hopeful that their new results will be utilitarian in agriculture in the future tense . Current agricultural practices trust heavily on the consumption of chemic crop protection that can be damaging for the environment . " say Berendsen . " Now we sleep together that plants can assemble a beneficial microbiome , we can make use of that in factory farm . "
Plant - Microbe InteractionsThis noesis could help make crop less qualified on pesticides . Berendsen : " For genus Arabidopsis industrial plant , we now know which specific bacterium the industrial plant recruit when infected with pubescent mildew , and we have an excellent basis to find out which mechanisms and genes are require in this disease - induced recruitment by this good example plant . We can then render these fundamental finding to more economically relevant crop species . We suppose crops can ultimately be bred in such a direction that they systematically create their own disease - suppressive soil . "
This survey was the result of a collaboration between the research groups Plant - Microbe Interactions ( lead by Prof. Corné Pieterse ) and Translational Plant Biology ( lead by Prof. Guido van den Ackerveken ) .
