Abstract

The FLO5 gene has been assigned to chromosomes I and VIII in Saccharomyces cerevisiae. According to the results obtained, flocculation of strain STX347-ID (reported as strain FLO5) is the result of two different genes: one of them is allelic to the previously reported FLO1 and located at 4.7 cM from PHO11 and 37 cM from ADE1 on chromosome I. The other was mapped on chromosome VIII at 36.8 cM from PET3 and 30.5 cM from FUR1. This second gene generated a constitutive flocculation phenotype that was not under the control of the fsu3 suppressor. The latter has been reported to suppress certain FLO1 genes.

摘要

FLO5基因已被定位到酿酒酵母的第I和第VIII号染色体上。根据所得结果，菌株STX347-ID（报告为FLO5菌株）的絮凝是两个不同基因作用的结果：其中一个与先前报道的FLO1等位，位于第I号染色体上距PHO11 4.7厘摩、距ADE1 37厘摩处。另一个定位在第VIII号染色体上，距PET3 36.8厘摩、距FUR1 30.5厘摩处。这第二个基因产生了一种组成型絮凝表型，不受fsu3抑制子的控制。据报道，后者可抑制某些FLO1基因。
