Tomato is an important crop which is grown worldwide and is an excellent experimental system....

Presence of phytochrome in two kinds of tomatoes (Lycopersicon esculentum Mill.), the yellow lutescent strain and cherry tomatoes (L. esculentum Mill. var. cerasiformecv. Red Cherry), was established by measuring the absorption difference spectra of the whole fruit after irradiation with red and with far red light. Phytochrome content was determined in yellow lutescent tomatoes and decreased gr...

Ferredoxin-glutamate synthase was localized in leaves and cotyledons of tomato (Lycopersicon esculentum, cv Hellfrucht früshstamm) seedlings by immunocytochemical methods. The present work established that the enzyme was not only a constituent of chloroplast stroma of the mesophyll cells, but also of the cells of xylem parenchyma and epidermis.
