To date quantitative trait loci (QTLs) conferring root architectural characteristics have been identified in some plants, offering hopes for molecular improvement of this trait.
迄今已在一些植物上定位到了部分控制根构型的数量性状座位，为该性状的分子生物学改良提供了基础。
The computation will be simplified, since the variable gain K would not appear in the equation of the root loci.
由于根轨迹方程中未出现可变增益K，从而使计算大为简化。比传统的伊文思法要简便准确得多。
