日本研究人员近日发表论文说,他们发现某些蚜虫的体色会因体内一种细菌的作用而由红变绿。研究人员指出,这一变化有利于它们躲避天敌瓢虫的袭击。日本理化学研究所研究员土田努率领的研究小组发现,这种细菌是在蚜虫体内定居的寄生细菌之一。寄生细菌对生物生存和适应环境非常重要。据悉这是首次发现能够改变生物身体颜色的寄生细菌。 Japanese researchers recently published a paper saying they found that the body color of certain aphids could turn from red to green due to the action of a bacterium in the body. The researchers pointed out that this change will help them to evade the predators ladybug attacks. A team led by researcher Tsuchihiro Tsuneo of the Japan Institute of Chemistry and Chemistry found that the bacteria was one of the parasitic bacteria that settled in aphids. Parasitic bacteria are very important for living and adapting to the environment. It is reported that this is the first time that parasitic bacteria can be found that can change the color of biological body.
