句中的that好象应该删去呀
that是什么用法?

that 作同位语,代替the publication by Science of Syngeta's rice genome article"represents a very serious threat to genomics research,这是固定的,不能去掉。
相似的有:fact,news ,......

THAT在这里是同位语从句的标志吧~~?

不能省略的,这里的THAT连词, the publication by Science of Syngeta's rice genome article"represents a very serious threat to genomics research ".是句子,如果没有THAT就成破句了

不能删除,

THAT作宾语从句的引导词.

that是一个词,它能在一些问题里出现!如Is that a appie?等
