Blakeslee, Albert Francis, Cartledge, J. Lincoln, Welch, Donald S. (October 1921) Sexual dimorphism in Cunninghamella. Botanical Gazette, 72 (4). pp. 185-219.
Abstract
1.The terms heterothallic and homothallic are distinguished as applied to gametophytic sexual differentiation in the mucors. 2. Types of the evidence in support of sex intergrades in heterothallic mucors are given and criticized. 3. Burger's paper on Cunninghamella, in which he concludes that sexual dimorphism does not exist in this genus, is discussed (1) from the standpoint of his own data, (2) from the standpoint of our experience, and the decision is reached that his conclusion is not warranted. 4. Data on Cunninghamella elegans, Cunninghamella A (an undetermined species), C. echinulata, and C. bertholletiae give a total of 2250 contrasts between a total of 202 races. 5. In C. bertholletiae certain contrast combinations lead to imperfect sexual reactions when zygospores might be expected. 6. In none of the species were races found which reacted as sex intergrades 7. It is concluded that so far as the material investigated is concerned Cunninghamella is sexually dimorphic.
