Table 2. Fiber differentiation processes on the DPA analyzed in these experiments.^a.

DPA	Fiber developmental processes in G. hirsutum	Fiber developmental processes in G. barbadense
10	rapid elongation	rapid elongation
14	rapid elongation	rapid elongation
17	rapid elongation; early transition stage with shifting gene expression	rapid elongation; early transition stage with shifting gene expression
19 and 21	slowing elongation; the CFML degrades and the winding layer is synthesized during the transition to secondary wall deposition	rapid elongation; the CFML degrades and the winding layer is synthesized during the transition to secondary wall deposition
24	secondary wall synthesis	secondary wall synthesis; rapid elongation
30	secondary wall synthesis	secondary wall synthesis; slowing elongation
35	secondary wall synthesis	secondary wall synthesis

^aBold types highlights a major difference between species, specifically the prolonged elongation period for G. barbadense fiber.
