M. xanthus是一种社会原核微生物，形成子实体和粘孢子。对M.分离出在结果形态发生中有缺陷的黄曲霉，并研究了这些突变体的成对混合物中的协同相互作用。某些成对的这些有果实缺陷的突变体混合在一起时可以结果。类似地，某些在标准结果条件下不能形成孢子的突变体在野生型或其他不形成孢子的突变体存在下可以形成粘孢子。成对的条件性非孢子形成突变体之间的协同作用模式定义了至少3组，可能是4组突变体，使得一组的成员不能彼此协同，但可以与其他组的成员协同。
M. xanthus, a social procaryotic microorganism, forms fruiting bodies and myxospores. A collection of mutants of M. xanthus that are defective in fruiting morphogenesis were isolated and synergistic interaction in pairwise mixtures of these mutants was studied. Certain pairs of these fruiting-defective mutants can fruit when mixed together. Similarly, certain mutants that cannot sporulate under standard fruiting conditions can form myxospores in the presence of wild-type or other nonsporulating mutants. The pattern of synergism between pairs of conditional nonsporulating mutants defines at least 3 and probably 4 groups of mutants, such that members of a group cannot synergize with each other but can synergize with members of other groups.
