Variation of the developmental features of the CFML by genotype. a Calcofluor staining of cross sections of developing and mature cotton fibres of PimaS7 and China10 (G. barbadense), FM966 (G. hirsutum), Krasnyj (G. herbaceum) and JFW15 (G. arboreum). Arrowheads point at enlarged region of the CFML in all cotton lines, arrows point to CFML bulges paired only in the G. hirsutum species. Extra-thickening secondary cell walls are highlighted with a yellow line in the JFW15, 25 dpa and mature panels. b Enlarged CFML regions (arrowheads) displayed variable sizes whereas the CFML bulges (arrows) were smaller than 1 μm and were mainly found in pairs in G. hirsutum. c Paired CFML bulges were also present in G. hirsutum ovules cultured in vitro. d Longitudinal section of 15 dpa FM966 fibres indicating the three dimensional structure of the enlarged CFML regions (arrowheads) and a longitudinal stripe along the fibre in the case of the CFML bulges (arrow). An indicated cross section of these fibres following the yellow line would show the image equivalent to B. Scale bars =10 μm. All images in a panel are at the same magnification
