Figure 1From: Construction of a plant-transformation-competent BIBAC library and genome sequence analysis of polyploid Upland cotton (Gossypium hirsutumL.)Analysis of BIBACs randomly selected from the Upland cotton cv. TM-1 BIBAC library. The BIBACs were digested with Not I and fractionated on a pulsed-field gel (A) and plotted according to their insert sizes (B). M, lambda ladder PFG marker; V, vector fragment; N, number of random clones analyzed for insert size estimation of the library.Back to article page
