...Ning Zhai; Xuan Pan; Minhuan Zeng; Lin Xu ABSTRACT In plant tissue culture, callus formation is induced by a high auxin concentration. Among the three cell layers (the outer, middle and inner cell layers) of the callus, pluripotency acquisition in the middle cell layer is required for the potential...

...H. Frederik Nijhout; Emily Laub; Laura W. Grunert ABSTRACT The wing imaginal disks of Lepidoptera can be grown in tissue culture, but require both insulin and ecdysone to grow normally. Here, we investigate the contributions the two hormones make to growth. Ecdysone is required to maintain mitoses...
