Until now, 83 sucrose transporter genes have been cloned in 31 dicotyledons and 6 monocotyledons.
目前已从31种双子叶植物和6种单子叶植物中克隆到83个蔗糖转运蛋白基因。

Monocotyledons and dicotyledons are so termed because they normally conatin one and two cotyledons respectively although there are exceptions.
尽管有例外的情况出现，我们通常还是根据子叶的数目为一片还是两片而把植物分成单子叶植物和双子叶植物。

The gene transformation by agrobacterium'plasmid is a perfect and effective method of transferring gene in the gene engineering, however, there is a little apply on the monocotyledons plants.
