证明了一种产生遗传马赛克的新方法,该方法涉及自由染色体片段的自发体细胞丢失。影响FC行为的四个基因。在马赛克动物身上进行了优雅的研究。野生动物的完整细胞谱系是已知的,这一事实极大地帮助了这一分析。其中两个突变基因会影响某些感官反应,并阻止某些感觉神经元摄取异硫氰酸荧光素(FITC)。马赛克分析表明,这些突变基因中的一个是细胞自主的,就其对FITC摄取的影响而言,另一个是细胞非自主的。在后一种情况下,围绕正常情况下吸收FITC的神经元突起的非神经元支持细胞的基因型可能是关键。另外两个突变基因会影响动物的运动。镶嵌分析表明,其中一个基因的表达是特定神经元所特有的(腹神经索和背神经索的运动神经元是首选候选),而另一个基因的表达是肌肉细胞所特有的。
A new method for producing genetic mosaics, which involves the spontaneous somatic loss of free chromosome fragments, is demonstrated. Four genes that affect the behavior ofC. eleganswere studied in mosaic animals. The analysis was greatly aided by the fact that the complete cell lineage of wild-type animals is known. Two of the mutant genes affect certain sensory responses and prevent uptake of fluorescein isothiocyanate (FITC) by certain sensory neurons. Mosaic analysis indicated that one of these mutant genes is cell autonomous with respect to its effect on FITC uptake and the other is cell nonautonomous. In the latter case, the genotype of a non-neuronal supporting cell that surrounds the processes of the neurons that normally take up FITC probably is critical. The other two mutant genes affect animal movement. Mosaic analysis indicated that the expression of one of these genes is specific to certain neurons (motor neurons of the ventral and dorsal nerve cords are prime candidates) and the expression of the other gene is specific to muscle cells.
