Our research establishes genetic linkage between the hph-1 mutation and the GTP-CH I structural gene. Our results indicate that these two loci are within an 8 cM region with 95% confidence. This finding lends additional ...

From ovulation to oviposition, the corpora lutea of the oviparous lizards Crotaphytus collaris and Eumeces obsoletus exhibit three stages of luteal development: 1) luteogenesis, 2) luteal maturity, and 3) luteal regression. ...

Treatment of hamsters on the day of birth with the synthetic estrogen and prototypical endocrine disruptor, diethylstilbestrol (DES), induces severe anomalies throughout the female reproductive tract. The disruption ...

The soilborne necrotrophic fungal pathogen Macrophomina phaseolina (Tassi) Goid causes charcoal rot disease in many economically important crops. There are no effective control methods for this disease and no completely ...

GTP cyclohydrolase I catalyzes the initial and rate limiting step of the biosynthesis of tetrahydrobiopterin, the cofactor for aromatic amino acid hydroxylation. The mouse mutant HPH-1, previously generated by chemical ...

Macrophomina phaseolina is a necrotrophic soil-borne fungal pathogen that causes a disease commonly known as charcoal rot. This fungus has the potential to infect over 500 different plant species worldwide including many ...

Three equine CG (eCG) forms with identical amino acid sequences but different mol wt and monosaccharide compositions were isolated from a crude eCG preparation and designated eCG-L (low mol wt), eCG-M (medium mol wt), and ...

In the Syrian hamster, neonatal diethylstilbestrol (DES) treatment and then postpubertal estrogen stimulation induces hyperplasia plus apoptosis (preneoplastic responses) and ultimately neoplasia in the endometrial epithelial ...
