摘 要 :利用cDNA芯片技术分析陆地棉显性单基因突变的李氏超短纤维突变体(Li1li1)和其野生型(li1li1)纤维发育4 DPA(day post anthesis)的基因差异表达情况。RT-PCR验证4DPA芯片结果,得到15个差异表达的EST(expressed sequence tag),其中9个下调表达,即野
Abstract:Cotton fibers are single-celled seed trichomes of major economic importance. Numerous investigations at both the ultrastructural and biochemical level have shown that fiber cells develop in four distinct but a little overlapping phases which are initiation, cell elongation (primary wall synthesis),
