Cotton provides us the most important natural fibre. High fibre quality is the major goal of
cotton breeding, and introducing genes conferring longer, finer and stronger fibre from G
ossypium barbadense to G ossypium hirsutum is an important breeding strategy. We
previously analysed the G. barbadense fibre development mechanism by gene expression
profiling and found two homoeologous fibre‐specific α‐expansins from G. barbadense, Gb
EXPA 2 and Gb EXPATR. Gb EXPA 2 (from the DT genome) is a classical α‐expansin, while …
