It is suggested that this chromosomeregion can be a candidate for fine mapping of QTLs related to root and grain yield traits.
因此，此染色体区段可能作为一个玉米根系与产量相关性状相关QTL精细定位的候选区域。

Centromere is the primary constriction on the chromosome, a region at which the sister chromatids are held together.
着丝点是染色体的主缢痕，在这个地方姐妹染色单体连在一起。
