Genetics and regulation of carotene biosynthesis

Pure and Applied Chemistry, 1979
Abstract Colour mutants are conspicuous and convenient genetic markers, but there have been few studies on the genetics of carotene biosynthesis. Recent work with the fungus Phycomyces has identified two main structural genes: carB , responsible for phytoene dehydrogenase, and carR , responsible for lycopene cyclase.

Genetic regulation of cerebellar development

Nature Reviews Neuroscience, 2001
The cerebellum is one of the first brain structures to begin to differentiate, yet it is one of the last to achieve maturity — the cellular organization of the cerebellum continues to change for many months after birth. This protracted developmental process creates a special susceptibility to disruptions during embryogenesis and makes the cerebellum ...

Genetic regulation of thymic involution

Mechanisms of Ageing and Development, 2005
In this review, we have summarized our work using combined complex statistical genetics, bioinformatics, and functional genomics to determine the genetic basis of the age-related thymic involution in C57BL/6J X DBA/2J recombinant inbred mice and the parental B6 and D2 mice. We have shown that these mice provided a valuable genetic model that can permit

Genetic regulation of androgen action

The Prostate, 1996
The androgen receptor (AR) belongs to the superfamily of nuclear receptors that employ complex genetic mechanisms to guide the development and physiological functions of different target tissues. Upon interaction with its cognate hormone, AR activates or represses gene transcription through association with specific DNA elements and/or proteins.

Genetic and epigenetic regulation of aging

Current Opinion in Immunology, 2009
Many age-associated conditions, such as the decrease in regenerative capacity of tissues, appear to be determined by a decline in the function of specific somatic stem cells. Although it is obvious that the genotype determines the average lifespan of different species, the variation in lifespan of individuals within a species seems to be more affected ...

GENETIC REGULATION OF BACTERIAL VIRULENCE

Annual Review of Genetics, 1989
In this review, we concentrate on genetic control of bacterial virulence. We limit this review to several systems that illustrate common molecular themes in control of virulence properties rather than presenting a comprehensive review of this extensive ...

Genetic regulation of self‐incompatibility

Critical Reviews in Plant Sciences, 1993
Abstract Self‐incompatibility is a cell‐cell recognition system in higher plants that is based on the ability of the pistil to discriminate “self‐pollen from “non‐self"‐pollen. In the simplest systems, this recognition response is controlled by a single locus — the S‐locus — with multiple alleles. Pollination of a pistil with pollen bearing an S‐allele

Genetics and Regulation of Nitrogen Fixation

Annual Review of Microbiology, 1981
The genetics and regulation of N2 fixation has only recently begun to be understood. Breakthroughs from a variety of laboratories have yielded both techniques and ideas that will be useful for understanding genetic and regulatory mechanisms of microbial N2 fixation.

Genetic regulation of thyroid development

Current Opinion in Pediatrics, 2001
Normal thyroid function is essential for development, growth, and metabolic homeostasis. The prerequisites for an euthyroid metabolic state include a normally developed thyroid gland, a properly functioning system for thyroid hormone synthesis, and sufficient iodine intake. Defects in any of the essential steps in thyroid development or thyroid hormone

Are Genetic Tests Adequately Regulated?

Science, 1999
T he Human Genome Project has engendered genohype, from early pronouncements that our destiny is in our genes to recent declarations that new discoveries will minimize or prevent the appearance of disease phenotypes altogether. With claims like these, it is no wonder that companies have sprung up to identify the presence of susceptibility-conferring ...
