A strange tale of collaboration between plants, pathogens and insects .

植物、病毒和昆虫的奇特合作。

CUCUMBER mosaic virus is not restricted to its eponymous host. It can also ravage tomatoes—stunting them and causing them to produce contorted tendril-like leaves. Given this devastation, it is surprising susceptible plants continue to exist; natural selection should have produced resistance years ago.

黄瓜花叶病毒能感染不是只有黄瓜。这种病毒也荼毒番茄——病株会长出卷曲的病叶。考虑到病毒的危害,至今还存在易感染植物着实让人惊奇——自然选择应该早在几年前就帮助它们形成了病毒抵抗力。

A paper in this week’s PLoS Pathogens, however, explains the apparent contradiction.

本周,PLoS Pathogens发表的一篇论文解释了这一明显矛盾。

The team that wrote it, led by John Carr of Cambridge University, found that the virus actually helps its host to reproduce. It does so using an unsuspecting accomplice: the bumble-bee.

发表这篇文章的团队由剑桥大学的约翰.卡尔带领,他们发现病毒实际上在帮助宿主繁衍。而达成这种目标借助的不是别的,正是大黄蜂。
