Ancestral capture of syncytin-Car1, a fusogenic endogenous retroviral

ABSTRACT
Syncytins are envelope protein genes of retroviral origin that have been
captured for a function in placentation. Two such genes have already
been identified in simians, two distinct, unrelated genes have been
identified in Muridae, and a fifth gene has been identified in the
rabbit. Here, we searched for s... 阅读全帖 |

aphids吸完树叶的汁后,排泄了蜂蜜状物质,然后就长真菌了。这个叫sooty mold.
可以经常用高压水枪冲,把上面的aphid冲下来。
要根治,用systematic insecticide. 不过对大树见效比较慢。
控制住aphid后,黑乎乎的东西就停止生长了。一两个月的风吹日晒之后会自然脱落。 |

Aphids are a common pests that can be found on the undersides of your
muskmelon leaves. You’ll know they’re there if you see leaves turning
yellow and crinkling or curling.

Aphids suck the juice from your plant leaves and leave a sticky substance

t*1 发帖数: 124 | 6 I also have trouble with Aphids. Strangely not all plants have this kind of
bugs. Only a certain kind of plants tend to have this problem.
I found if you constantly apply insecticide to the plants, your palnts will
have less aphids, but I don't think it will eliminate all of them. |

Could the first one be aphids? Aphids are roundish and cannot move fast,
although they do crawl. I posted an article on this board a couple of weeks
ago. Please compare your bug with the ones in the first picture.
