Morphological Analyses of a Stable Cotton Homeotic Variant (chv1)

Physiological and genetic variations exist richly in the cotton plants regenerated from somatic embryo. A stable homeotic variant (chv1) of cotton from regenerated plants was identified.Using light microscope and scanning electron microscope to investigate the morphological changes in chv1, the results revealed that all the floral organs in the chvl1 plants converted into leaves, meanwhile the placenta and ovules bearing on the basal part in central leaf-like organs can be discerned. ……
