Artificial selection for modified phenotypes has occurred since the dawn of agriculture and is responsible for many commercially available fruits and vegetables today. Clarkia tembloriensis is a California wildflower expressing fasciation in certain populations when grown under abnormal environmental conditions in a laboratory setting. This makes it an excellent model organism to study the effect of abnormal environmental conditions on the expression of fasciation. In this investigation, shoot apex morphology and anatomy were observed throughout the development of wild-type plants and those expressing fasciation via scanning electron microscopy (SEM) and light microscopy. These observations revealed morphological and anatomical abnormalities of shoot apical meristem (SAM) development including an enlarged ring-shaped meristem, abnormal organs, and callus tissue. Comparing these observations with current literature for genetic and hormonal interactions in the SAM of plants, it is proposed that ring fasciation and callus formation in Clarkia tembloriensis occur as a result of abnormal environmental conditions via abnormal signaling of phytohormones and other developmental regulators which function in maintenance of meristem size and organ initiation. 2019-11-26 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1574731415182166 http://rave.ohiolink.edu/etdc/view?acc_num=miami1574731415182166 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
