PHYSIOLOGICAL CHARACTERIZATION OF A HIGH‐PIGMENT MUTANT OF TOMATO [PDF]

open access: yesPhotochemistry and Photobiology, 1992
Abstract— A high‐pigment (hp) mutant, which shows exaggerated phytochrome responses and three other genotypes of Lycopersicon esculenrum Mill. cv. Ailsa Craig: the aurea (au) mutant deficient in the bulk light‐labile phytochrome (PI) pool, the au, hp double mutant, and their isogenic wild type, were used in this study.

Tissue Pigment Manifestations of Adaptation to High Altitudes

American Journal of Physiology-Legacy Content, 1957
Studies on the pigment content of muscle and organ tissues of sea level and altitude (14,900 ft.) guinea pigs have demonstrated a significant increase in myoglobin in several skeletal muscles, heart and liver in sea level animals kept in the altitude for an average of 75 days. Smaller increments were indicated for the myoglobin and cytochrome c levels

Pigmentation Due to Phenothiazincs in High and Prolonged Dosage

Journal of Occupational and Environmental Medicine, 1965
Seventy-eight patients receiving abnormally high doses of chlorpromazine and related phenothiazine derivatives for prolonged periods developed pigmentary changes in the exposed areas of the skin after exposure to specific bands of sunlight. Histochemical studies suggested that this color was melanin or a melanin-like substance. The phototoxic action of

The high calcium content of retinal pigmented epithelium

Experimental Eye Research, 1975
Abstract The concentration of calcium was measured in isolated retinal pigmented epithelial cells, erythrocytes, whole retina, and rod outer segments of bullfrogs. The tissues were solubilized in an organic base and calcium was determined by flameless atomic absorption spectrophotometry.

High biological variability of plastids, photosynthetic pigments and pigment forms of leaf primordia in buds

Planta, 2011
To study the formation of the photosynthetic apparatus in nature, the carotenoid and chlorophyllous pigment compositions of differently developed leaf primordia in closed and opening buds of common ash (Fraxinus excelsior L.) and horse chestnut (Aesculus hippocastanum L.) as well as in closed buds of tree of heaven (Ailanthus altissima P.
