Defining the Transition from Cell Elongation to Secondary Cell Wall Biosynthesis:Promoter Analyses,Transcript Profiling,and Genomic Analysis of Near-isogenic Germplasms that Differ in Fiber Strength

A distinct set of homoeologous cellulose synthase catalytic subunit(CesA) genes are coordinately up-regulated with the onset of secondary wall formation in cotton fiber as shown by quantitative-RT-
