InterventionCaloric restriction
Alternate Name
OrganismAsplanchna brightwelli
Aging PhenotypeLife-span extension
Allele TypeN/A
StrainUnknown
DescriptionReduction of the paramecium concentration to below 100/mL results in dietary restriction and life-span extension of approximately 15% in the rotifer Asplanhna brightwelli (Sawada and Enesco, 1984). Food restriction by increasing the interval between feedings also extends life-span (Verdone-Smith and Enesco, 1982).
Gene Function
Other PhenotypesFood restriction increases the length of the reproductive period (Verdone-Smith and Enesco, 1982).
The rate of nuclear division in the gastric glands and vitellarium of the rotifer, as determined by daily nuclear counts, is retarded by dietary restriction (Verdone-Smith and Enesco, 1982).
