Many parasites rely on a host body to control spread, such as iron nematodes by force cricket host drowned in the water has entered the water, the infected liver fluke driver ants climb up the grass eaten by cows so as to be in order to achieve the purpose of parasitism.
However, parasites can be plants into zombies, John Innes Institute in Norwich, UK scientists have discovered the mystery.
When the plant is one kind of phytoplasma named (Phytoplasmas) parasitic bacterial infection, they become multi-leaf flower seedlings, they become green petals and a large number of development known as "witches broom" seedlings. This change makes the sterilization plant therefore attracts both sucking insects carry the bacteria go into a new host body.
"These plants look alive, but only to the bacteria in the service." John Innes Institute of Plant Pathology expert Saskia Hogenhout said, "From an evolutionary perspective, the plant is dead and will not breed."
Hogenhout research team has previously confirmed by bacteria called SAP54 protein alone to manipulate its host. This protein with one called RAD23 protein interactions of plants, will make one kind of cell destruction of the target molecule is passed to the cellular waste treatment center - the proteasome. In the previous example, it is being targeted molecules that control flowering. The relevant papers have been published in PLoS Biology.
SAP54 between the plant proteins in the same plant interactions also increase the attractiveness of the leafhopper delivery of phytoplasma. The team found leafhoppers on the plants infected with a leaflike flower production under more eggs. They also confirmed that even if only SAP54 and not the bacteria themselves, can also attract leafhoppers.
Pennsylvania State University plant pathologist David Hughes said that this bacterium can be used simultaneously with a protein that controls the plants and insects, is lovely.
Hogenhout believe that this discovery reveals the relevance of plant growth and immune system mechanisms, which have never been thought and doubted, and is likely to exist in other species body. She also wished to study this association will be able to develop and improve crop yields and new means of expediting resist pests.
She also wished to know what other kinds of bacteria related to the manufacture of zombies plants. For example, one called Puccinia monoica sterilization of rust and make a host into a bright yellow foliage "Passion." These artificial flowers filled with a fungal cell, attract pollinating insects and the cells spread through them to the new uninfected hosts. Nobody knows how they are reshaping the host, Hogenhout said, "find out how things will cool thing!"
