Fig. 2From: Identification and profiling of upland cotton microRNAs at fiber initiation stage under exogenous IAA applicationDifferences in the initial development of fibers at 0 DPA between control (CK) and IAA treated (IT) plant. a and b show CK ovules surfaces at 80× and 2000× magnification; (c) and (d) show IT ovules surfaces at 80× and 2000× magnification. b and d are the black frame aeras of (a) and C. It was indicated that the number of lint fiber on ovules of IT was much higher than that of CK, and the size of of lint fiber on ovules of IT was much larger than that of CKBack to article page
