Red light, mediated by the photoreceptor phytochrome, induces maize leaf unrolling as well as leaf expansion. Protoplasts prepared from maize leaves still in the rolled condition swell in a red-far red photoreversible manner indicating that phytochrome mediates this phenomenon. To determine if proto

Protoplasts from dark-grown wheat (Triticum aestivum L.) maintained at a constant osmotic potential at 22ยฐC, were found to swell upon red irradiation (R) and the effect was negated by subsequent far-red light (FR), indicating phytochrome involvement. Swelling only occurred when Ca(2+) ions were pres
Transient gene expression was studied in isolated protoplasts of barley (Hordeum vulgare L. cv Himalaya) transformed by electroporation. Two plasmid constructions were used, both of which contained the gene coding for neomycin phosphotransferase II (nptII) as a reporter gene. In one plasmid the repo
The present paper is part of a research program which aims at a quantitative analysis of the effects of light and gibberellic acid (GA3) on growth of the first foliage leaf in durum wheat (Triticum durum Desf.). Since leaf growth is the combined result of the increase in cell number (cell division)
