|a Fibre cell initiation and elongation is critical for cotton fibre development. However, little is known about the regulation of initiation and elongation during fibre cell development. Here, the regulatory role of a novel protein GhCFE1A was uncovered. GhCFE1A is preferentially expressed at initiation and rapid elongation stages during fibre development; in addition, much higher expression of GhCFE1A was detected at the fibre initiation stage in fibreless cotton mutants than in the fibre-bearing TM-1 wild-type. Importantly, overexpression of GhCFE1A in cotton not only delayed fibre cell elongation but also significantly reduced the density of lint and fuzz fibre initials and stem trichomes. Yeast two-hybrid assay showed that GhCFE1A interacted with several actin proteins, and the interaction was further confirmed by co-sedimentation assay. Interestingly, a subcellular localization assay showed that GhCFE1A resided on the cortical endoplasmic reticulum (ER) network and co-localized with actin cables. Moreover, the density of F-actin filaments was shown to be reduced in GhCFE1A-overexpressing fibres at the rapid elongation stage compared with the wild-type control. Taken together, the results demonstrate that GhCFE1A probably functions as a dynamic linker between the actin cytoskeleton and the ER network, and plays an important role in fibre cell initiation and elongation during cotton fibre development
